Abstract
La asociación fósil de la Formación de Tagatiya Guazu (Grupo ediacárico de Itapucumi, Paraguay) representa una oportunidad única para investigar los parámetros paleoecológicos y contribuir con información taxonómica sobre las asociaciones de Cloudina en Gondwana SW.
Highlights
Cloudina is one of the main index fossils of the Ediacaran Period commonly occurring in carbonate platform settings as in situ clusters or loosely packed parautochthonous bioclastic deposits in close association with microbial facies
Reassessing the taphonomy of in situ Cloudina assemblages from the Tagatiya Guazu Formation, Ediacaran Itapucumi Group, Paraguay
One of the greatest issues concerning the interpretation of Cloudina palaeobiology is related to the preservational quality of the fossils, which varies according to distinct rock matrixes, in some cases precluding the precise interpretation of its tridimensional morphology
Summary
Cloudina is one of the main index fossils of the Ediacaran Period commonly occurring in carbonate platform settings as in situ clusters or loosely packed parautochthonous bioclastic deposits in close association with microbial facies. Reassessing the taphonomy of in situ Cloudina assemblages from the Tagatiya Guazu Formation, Ediacaran Itapucumi Group, Paraguay. Size distribution of tubes in autochthonous Cloudina assemblages has demonstrated to be a useful, and sometimes the only approach possible to define taxonomic characters and assess information on the structure of palaeocommunities, modes of reproduction and ontogeny.
