A low-diversity Peruvispira-dominated gastropod assemblage from the Permian Ratburi Group of Central Thailand

Permian gastropods from Thailand have been extensively studied over the last few years. The earliest known fossil collection was recovered in 1967 but has never been figured or described. Here, we document this historically important gastropod assemblage excavated from the upper-Lower to Middle Permian Ratburi Group of Khao Mang Lat in the Ban Kao District of Kanchanaburi Province, Central Thailand. The material comprises approximately 200 specimens, almost all of which represent a new species, Peruvispira kanchanaburiensis sp. nov. (Goniasmatidae), together with a single individual of Orthonychia sp. (Orthonychiidae = Platyceratidae). This exceptionally low-diversity community is unusual in comparison to Permian gastropod faunas reported from elsewhere, and could reflect either a low temperature palaeoenvironmental setting or priority effects resulting from early establishment of planktotrophic larvae within the local habitat.

Thailandina and Neothailandina and their family Thailandinidae salvaged: a valid taxonomic group of peculiar Permian fusuline Foraminifera

The fusuline genera Thailandina Toriyama and Kanmera, 1968 and Neothailandina Toriyama and Kanmera, 1968 were established by Toriyama and Kanmera (1968) based on material from the Khao Phlong Phrab section of the Permian Rat Buri Limestone in central Thailand that is currently assigned to the Khao Khad Formation of the Saraburi Group (Ueno and Charoentitirat, 2011). These fusuline genera are peculiar in having parachomata and replaced tests by secondary mineralization. Moreover, Neothailandina was described to have a test with transverse septula, considered to be characteristic for Neoschwagerinidae. Based on these remarkable test features, Toriyama and Kanmera (1968) newly introduced the subfamily Thailandininae to accommodate these two new genera and assigned it to the Neoschwagerinidae, despite the lack of septula in Thailandina. Later, Kobayashi et al. (2010) argued that Thailandina and Neothailandina are just a mixed grouping of several known genera of schwagerinids, verbeekinids, and neoschwagerinids that are too altered by recrystallization to be recognizable, and rejected the taxonomic validity of these two genera as well as Thailandininae.The Khao Phlong Phrab section represents one of the standard late Cisuralian−Guadalupian (late early−middle Permian) fusuline successions in the eastern Paleotethys (Zhang and Wang, 2018) and contains not only Thailandina and Neothailandina but also abundant schwagerinid, verbeekinid, and neoschwagerinid fusulines (Toriyama, 1975; Fig. 1). I investigated the original specimens described by Toriyama and Kanmera (1968) and Toriyama (1975) from the section that are housed in the Department of Earth and Planetary Sciences of Kyushu University, Japan. I found that most of the grounds for Kobayashi et al.'s (2010) arguments to regard the thailandinin genera as taxonomically invalid are not supported by observations on these specimens as explained in the account that follows. In this taxonomic note, I propose that Thailandina and Neothailandina, and their family Thailandinidae, should be retained as valid taxonomic groups.

Integrated techniques for the structural assessment of cultural heritage masonry buildings: application to Palazzo Cocchi-Serristori in Florence

PurposeThis paper aims to contribute to the discussion of the experimental campaigns on Cultural Heritage buildings. By adopting integrated procedures it is possible to limit the invasiveness of the destructive techniques leading to reliable results. The purpose is the proper definition of the structural system, which represents the starting point of the following analysis's phases, not treated in this work. A methodology based on normative references and acknowledged non-destructive and partial destructive strategies has been conceived. The latter aims to an accurate comprehension of the structural information.Design/methodology/approachAn integrated approach for the structural assessment of cultural heritage buildings is presented. The methodology defines an interdisciplinary procedure based on normative references, non-destructive and minor-destructive techniques. A funnel-shaped workflow is developed to characterize the structural system of the buildings. The non-destructive campaigns are widely extended. Then, in-depth analysis concerning partial demolitions and minor-destructive tests are performed. The dynamic identification of the building is executed to detect its global response. The final validation of the assumed mechanical values is obtained by comparing the experimental modes coming from the ambient vibrations and the analytical modes of the structural modelling.FindingsThis research belongs to the Protocol signed between the Municipality of Florence and Department of Earth's Science and Department of Architecture of the University of Florence for the seismic vulnerability assessment of relevant and strategic buildings.Research limitations/implicationsThe descripted methodology is targeted for monuments and special buildings where the use of destructive techniques is not possible or unrecommended.Social implicationsSocial implications are related to the conservation of Heritage buildings. The latter deals with: (1) risk assessment of the targeted buildings towards different hazard sources (e.g. earthquakes, floods); (2) knowledge path developed through non-invasive diagnostic campaigns oriented to the conservation of the manufact. Furthermore, the paper encourages towards the recognition of non-destructive techniques and ambient vibration tests for the achievement of higher knowledge levels.Originality/valueThis paper defines a funnel-shaped procedure defining hierarchical roles between the different available strategies. The originality of this contribution is firstly related to the methodological flowchart. It is targeted to limit the invasive tests and consequently achieving accurate levels of knowledge. Secondly, some novelty can be found in the adoption of improvement parameters from a regional database adopting a Bayesian approach.

Cambrian helcionelloids (univalved molluscs) from the Korean Peninsula: systematic revision and biostratigraphy

Helcionelloids from the Korean Peninsula are revised based on a re-examination of type specimens and new material collected from the Cambrian Mungyeong Group of South Korea. The fauna comprises Coreospira rugosa, Hampilina goniospira, Dorispira pacifica, cf. Igorella coreanica, and Helcionelloid indet. Coreospira and Hampilina are distinguished from other helcionelloids by their angular junction between dorsal and lateral surfaces, and from each other by the presence or absence of a rounded ridge along the junction, respectively. The Korean helcionelloids range stratigraphically from the base of Maochuangian to the lower Hsuchuangian using the chronostratigraphical scheme from North China; this correlates with upper Stage 4 to the lower Wuliuan Stage. Unusual septal features, such as complex suture lines in Hampilina and a central circular structure in the simple convex septa of Coreospira, occur in the apical region of the Korean helcionelloids, and could have implications for univalved molluscan evolution.

Research on climate change adaption in cities, funded by ERCA

There is growing global concern over climate change and research is being conducted to investigate the impact this phenomenon will have on the world. To support this research the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) has developed the d4PDF, the world's largest collection of simulation data about climate change. Professor Masaru Inatsu, from Department of Earth and Planetary Science at Hokkaido University, is working alongside Associate Professor Tetsuya Takemi, from Kyoto University, and Professor Hiroyuki Kusaka, from University of Tsukuba, in collaboration with a number of research partners from other leading research groups, to use this data to enable a better understanding of the impact of extreme weather on major cities in Japan.

Numerical modeling for coastal environmental monitoring: oil spills simulation along the lower Adriatic coasts

The Mediterranean Sea is one of the high-risk areas for oil spills. In fact, along the coasts, there is a total annual traffic of about 200.000 large ships. In particular, oil traffic in the Mediterranean represents about 20% of the world’s maritime hydrocarbon traffic and amounts to over 360 million tons per year. Over the years, numerous environmental disasters have occurred caused by the sinking of oil tankers and which had a devastating impact on the entire coastal ecosystem. Among the most important disasters that occurred in the Mediterranean, there was the one caused by the Haven oil tanker sinking in the sea near Genoa in April 1991 where about 144.000 tons of crude spilled out in the sea. This study reports the simulation results of potential hydrocarbon beaching due to spills of petroleum products at sea and attributable to maritime accidents or accidents on offshore oil platforms. In particular, the lower Adriatic area was analyzed where, on the coastal strip, there is an important ecosystem preserved by the Regional Natural Park of the Coastal Dunes (BR). The study is part of the research project “SIAT - Integrated UAV / UTV system with remote control for the pollutants dispersion assessment in the coastal environment for remediation” in collaboration with the Department of Earth and Geoenvironmental Sciences of the University of the Bari, Serveco Srl and LETG (Littoral, Environnement, Teledetection, Geomatique CNRS) in Rennes, which aims to develop new monitoring and analysis technologies of the anthropic impact on coastal systems.

Geogymkhana-Alicante (Spain): Geoheritage Through Education

In recent years, the dissemination of geoheritage has made great strides in Spain, both at the legislative and outreach levels. As part of these efforts, the Department of Earth and Environmental Sciences at the University of Alicante organizes various activities to promote and enhance the learning of geology and the geoheritage of Alicante Province (Spain). One of these activities is Geogymkhana-Alicante, a key initiative for secondary schools that combines scientific, playful, and didactic elements. Organized annually since 2012, around 8000 students from 74 secondary schools have participated. The Geogymkhana consists of 10 guided stops along a 3 km-long coastal itinerary near Alicante city. These high-quality easily accessible outcrops are relatively close to numerous secondary schools, thereby allowing students to learn about their local geoheritage. The Geogymkhana is run by about 50 staff, including professors, undergraduate geology students, and other support staff from the university. Diverse pedagogical strategies create an enjoyable, yet scientifically sound, educational itinerary. Some stops (such as the “Miocene Strata” or “Discontinuous Geological Record”) comprise mainly explanations, whereas other stops (such as “Geological Time Race” or “Human Stratigraphic Superposition”) are based on games and dynamic activities. In short, Geogymkhana-Alicante is an effective tool to spread geoheritage knowledge amongst secondary school students. Moreover, it offers an inspiring model for implementation in other locations.

The protégé effect in the retention of underrepresented minority undergraduate teaching assistants in geoscience: Preliminary indications from Newark, New Jersey

A summer scholars institute to introduce urban underrepresented minority (URM) high school students to applied geosciences at Rutgers University in Newark, New Jersey, had the unanticipated effect of markedly increasing (a) retention of undergraduate URM geoscience majors who served as teaching assistants in the institute and (b) recruitment of URM college students to the geoscience program. A study of the URM teaching assistants shows that they felt responsible to serve as positive role models for the URM high school students. As a result, the teaching assistants became committed to succeeding in college and in careers in the geosciences. This attitude is attributed to the protégé effect. The camaraderie of the teaching assistants formed the basis of a self-supporting learning/social community of URM geoscience majors within the Department of Earth and Environmental Sciences at Rutgers University that attracted URM students from other majors. The recruitment of high school students had no impact on department enrollment until at least 3 years later. As a result of this retention and recruitment, the percentage of URM students in the department increased to approximately 50% and enrollment doubled in 3 years. Using the protégé effect is a potential best practice for increasing diversity in the geosciences, especially in urban areas.

Phylogenetic placement of fossil gobies: An integrative approach

Event Abstract Back to Event Phylogenetic placement of fossil gobies: An integrative approach Christoph Gierl1, Martin Dohrmann1 and Bettina Reichenbacher1* 1 Ludwig Maximilian University of Munich, Department of Earth and Environmental Sciences, Palaeontology & Geobiology , Germany Gobioidei (gobies) comprise one of the most diverse groups of vertebrates, encompassing more than 2200 species in 320 genera, which can be found in freshwater, brackish, and marine habitats. Their high adaptiveness is indicated in surprising ways, e.g. guardian gobies sharing shelter with a shrimp, or mudskippers with a markedly amphibious lifestyle. Compared to the gobies’ modern diversity, their fossil record is rather sparse, currently amounting to approximately 70 otolith-based species and around 30 skeleton-based species. The systematic assignment of these fossils is often problematic, because most of them preserve few of the characters that define extant genera and even families, and no phylogenetic framework incorporating morphological data has yet been developed. Here we address this issue in an effort to more accurately assign fossils and better understand the evolutionary history of the gobioids. We have assembled a morphological character matrix comprising all currently recognized recent gobioid families, each represented by at least two species, and including eight fossil species from the Oligocene and early Miocene. We analyzed this matrix in combination with published molecular sequence data using a Bayesian approach. In the inferred total-evidence phylogeny, all extant families were recovered as monophyletic. Most of the fossil taxa were placed in the tree in accordance with their tentative assignments in previous studies based on comparative morphology alone. Our results support resurrection of the Oligocene family †Pirskeniidae and indicate that †Eleogobius and †Paralates are also best classified as separate extinct families. The integrative approach established here will be an invaluable tool for future interpretations of gobioid fossils.

Different levels of amphibious adaptation in three mudskipper species from the Persian Gulf: Insights from skeleton and otolith characteristics

Event Abstract Back to Event Different levels of amphibious adaptation in three mudskipper species from the Persian Gulf: Insights from skeleton and otolith characteristics Mehdi Ghanbarifardi1, Carolin Gut2, Zeinab Gholami2, Hamid Reza Esmaeili3, Christoph Gierl2 and Bettina Reichenbacher2* 1 University of Sistan and Baluchestan, Department of Biology, Faculty of Sciences, Iran 2 Ludwig Maximilian University of Munich, Department of Earth and Environmental Sciences, Palaeontology and Geobiology, Germany 3 Shiraz University, Department of Biology, College of Sciences, Iran Mudskippers are amphibious gobies (Teleostei: Gobioidei) that have served as models for the specialised physiology and behaviour of fishes out of water. Here we present new data on the skeletons and otoliths of three endemic mudskipper species from the Persian Gulf, i.e. Boleophthalmus dussumieri, Scartelaos tenuis and Periophthalmus waltoni, supplemented by one specimen each of Periophthalmodon schlosseri and Pn. freycineti from a museum collection. The species investigated are known for their different levels of amphibious adaptation, which allowed us to examine whether their skeletal and otolith characters might also reflect associated functional constraints. Based on X-ray and SEM imaging, we show here that the five species studied share three exceptional characters. One concerns the principal caudal rays, one relates to the caudal endoskeleton, and one to the otolith. A relationship between character innovation and degree of amphibious adaptation can be suggested for two of these traits. Our data also reveal that the Periophthalmodon and Periophthalmus species have three further exceptional characters of the caudal endoskeleton in common. Moreover, three additional unique traits, two related to the caudal endoskeleton and one to the otolith, were identified in Ps. waltoni. Following previous work on mudskipper locomotion, we suggest that the particular traits of the principal caudal rays and caudal endoskeleton developed in response to the extra stresses imposed on the tail when the fish moves about on land or is performing terrestrial jumps (skipping). The unique characters related to the otoliths may be linked to specialization in intraspecific acoustic communication via the wet substratum of emerged mudflats, but further work is needed to support this assumption. Our new data may also facilitate recognition of fossil species of mudskippers – which are currently unknown – as both skeletons and otoliths have good fossilization potential.

Palaeobiological features of the coralomorph Amsassia from the Late Ordovician of South China

Lee, M., Elias, R.J., Choh, S.-J. & Lee, D.-J., 25 May 2018. Palaeobiological features of the coralomorph Amsassia from the Late Ordovician of South China. Alcheringa 43, 18–32. ISSN 0311-5518.Amsassia yushanensis sp. nov. occurs in the Late Ordovician Xiazhen Formation at Zhuzhai, Jiangxi Province of southeastern China. This species is characterized by typical phacelocerioid organization of modules comparable with the other Amsassia species described in recent literature. Bipartite fission, in which a parent module divided into two parts, is by far the most common type of increase in this species; tripartite and quadripartite types of axial fission do occur but are relatively uncommon. Processes of module division are similar to those of A. shaanxiensis and A. koreanensis, and also occurred in tetradiids. In A. yushanensis, restoration of coralla was occasionally accompanied by recovery of a damaged or injured module or group of modules probably following an influx of sediment, as observed in some favositoid corals. Amsassia superficially resembles Lichenaria, a representative genus of the most primitive stock of tabulate corals of Ordovician age, and has likely been mistakenly identified as Lichenaria in the North China Platform. Available information suggests that the validity of a reported occurrence of Lichenaria in the South China Platform is also questionable.Mirinae Lee [mirinae.lee@kopri.re.kr] Division of Polar Earth-System Sciences, Korea Polar Research Institute, 21990, Incheon, Republic of Korea; Robert J.

A mosasaur fauna (Squamata: Mosasauridae) from the Campanian (Upper Cretaceous) of Hannover, northern Germany

Hornung, J.J., Reich, M. & Frerichs, U., February 2018. The mosasaur fauna (Squamata: Mosasauridae) from the Campanian (Upper Cretaceous) of Hannover, northern Germany. Alcheringa 42, 543-559. ISSN 0311-5518. Isolated teeth and a humerus from the Campanian of Hannover indicate a considerable local diversity of mosasaur taxa. The lower Misburg Formation (lower Campanian of the Lehrte West Syncline) yields Clidastes sp. (Mosasaurinae), Prognathodon sp. (Mosasaurinae), ?Hainosaurus sp. (Tylosaurinae) and an unidentified mosasaurid. It further confirms the presence of the genus Clidastes in northern central Europe and also proves the early Transatlantic distribution of a basal member of Prognathodon during the lower Campanian. ?Hainosaurus sp. is similar to roughly contemporaneous material of Hainosaurus sp. from southern Sweden. The upper Misburg Formation (upper upper Campanian) shows a different taxonomic composition with Tylosaurus sp. (Tylosaurinae), a second indeterminate species of Prognathodon and ?Platecarpus sp. The limited material of Prognathodon sp. shows closest affinities to P. lutugini (Yakovlev) from eastern Europe. The records of Tylosaurus and ?Platecarpus are among the stratigraphically youngest of these taxa. Facies and lithology of the Misburg Formation indicate that the mosasaurs lived in an open marine, mid-sublittoral environment with a water-depth around 70–100 m. In the contemporaneous chalk facies, deposited in somewhat deeper waters, as well as in shallow littoral deposits, mosasaurs are very rare and of lower diversity. Jahn J.
