Collection methods and comments
| Reason for describing collection: | taxonomic analysis | Collection dates: | 2007-2008 |
| Taxonomic list comments:"The bed contains both isolated bones and skeletons of amphibian juveniles (mainly Karpinskiosauridae; Bulanov, 2010), which are deformed and disarticulated to a varying degree. The remains of juvenile temnospondyls occurred much less often in the bed, as with isolated bones of their adults, which were mostly detected in the roof of the bed. The presence of predatory and herbivorous therapsids, as well as the diapsid reptiles in the assemblage of the locality was inferred from the presence of a few isolated small teeth, jaw fragments, and individual postcranial elements, but the incompleteness of the remains precluded their taxonomic identification. Moreover, dentary fragments identified as those of Kinelia sp. were detected in Monastyrskii Ovrag-D" (Bulanov, 2020) | |
