Abstract

Cretaceous-Paleogene flysch represents the youngest formation in the Budva Zone. Although the Maastrichtian-Lower Eocene age of these rocks has been well documented in the literature, trace fossils are only mentioned as abundant and not described. In the present paper, only a small number of ichnotaxa from Mide locality has been described, including Lorenzinia carpathica (ZUBER), Nereites irregularis (SCHAFHAUT), Scolicia plana KSI??KIEWICZ and Paleodictyon latum VIALOV & GOLEV. They confirm deepsea environment.

Highlights

Cretaceous-Paleogene flysch formation of the Budva Zone stretches along the Montenegrian coastal region from the cities of Herceg-Novi towards Budva and Bar, from where it passes along the southern side of Rumija mountain into Albania
Since Eocene flysch sediments are more common in the South Adriatic Zone of the Montenegro coastal region, which is underlying the Budva Zone, it is more likely that these ichnofossils originate from these sediments
Four ichnotaxa: Lorenzinia carpathica (ZUBER), Nereites irregularis (SCHAFHÄUT), Scolicia plana KSIĄŻKIEWICZ and Paleodictyon latum VIALOV & GOLEV have been identified from the Cretaceous-Paleogene flysch of the Budva Zone

Summary

Introduction

Cretaceous-Paleogene flysch formation of the Budva Zone stretches along the Montenegrian coastal region from the cities of Herceg-Novi towards Budva and Bar, from where it passes along the southern side of Rumija mountain into Albania. Four ichnotaxa: Lorenzinia carpathica (ZUBER), Nereites irregularis (SCHAFHÄUT), Scolicia plana KSIĄŻKIEWICZ and Paleodictyon latum VIALOV & GOLEV have been identified from the Cretaceous-Paleogene flysch of the Budva Zone. Scolicia plana KSIĄŻKIEWICZ from Mide locality was found on the lower bed-surface of sandstone layer. It was previously described as Subphyllochorda striata KSIĄŻKIEWICZ. UCHMAN (1998) has described the link between this form and Scolicia plana KSIĄŻKIEWICZ, that is described from an upper surface of layers and considers them the same ichospecies Both forms represent traces made by irregular echinoids. New finding of Lorenzinia carpathica (ZUBER) in the Cretaceous-Paleogene flysch formation of the Mide locality indicates that the specimen described by GRUBIĆ (1961) found between the the locations of V. Even though incipient Paleodictyon has been found in recent sediments on the deep-sea floor (RONA et al, 2009), it is still unknown what kind of organism produce this trace fossil
