Abstract While some Upper Paleozoic basins in central-western Argentina have been extensively studied, others have poorly understood biostratigraphy. The current biozone heterogeneity between basins could be an artefact of incompletely sampled invertebrate fossil assemblages preventing precise correlations. Here, we therefore provide a taxonomic assessment of brachiopods recovered from fossil-bearing

Abstract A review of the Southern Hemisphere Mesozoic tribosphenic mammal fossil record supports the hypothesis that Tribosphenida arose in the Southern Hemisphere during the Early Jurassic, around 50 million years prior to the clade’s reliably dated first appearance in the Northern Hemisphere. Mesozoic Southern Hemisphere tribosphenic mammals are known from Australia, Madagascar, South America and

Abstract Koreatriassothemis elongatus gen. et sp. nov. is the first representative of the odonatan superfamily Triassolestoidea described from the Upper Triassic of the Republic of Korea. Despite close similarities with the genera Pseudotriassothemis and Triassoneura, exact affinities within Triassolestoidea remain uncertain, thus discoveries of more complete triassolestoid fossils are required to

A new species of Attinopora (Bryozoa, Cinctiporidae) from the early Miocene of Atlantic Patagonia Alcheringa (IF 1.3) Pub Date : 2022-10-20 Juan López-Gappa, Leandro Martín Pérez
Abstract Cinctiporidae is a family of cyclostome bryozoans that ranged from the Paleocene to Recent; however, they also include a questionable record from the Upper Cretaceous of South Africa. Most cinctiporids occur in the Paleocene to Pleistocene strata of New Zealand and the Chatham Islands, with only two living species now found in New Zealand. This study confirms the presence of cinctiporid bryozoans

A new Cretaceous fossil mammal locality from the Bass Coast of southeastern Australia Alcheringa (IF 1.3) Pub Date : 2022-10-20 Thomas H. Rich, Melissa Lowery, Michael Hall, Lesley Kool, Joseph Bevitt, Matt White, Patricia Vickers-Rich
Abstract Mesozoic mammals from the polar regions of Australian Gondwana are exceptionally rare. The recovery of a partial jaw attributable to the australosphenid Ausktribosphenos nyktos from a new locality along the Bass Coast of Victoria is, therefore, significant because it comes from an uppermost Barremian to lowermost Aptian grit with abundant plant material that differs lithologically from other
