Early and middle Paleozoic gastropod protoconchs generally differ strongly from their corresponding adult morphologies, that is, most known protoconchs are smooth and openly coiled, whereas the majority of adult shells are ornamented and tightly coiled. In contrast, larval and adult shells of late Paleozoic gastropods with planktotrophic larval dev...

The Pennsylvanian Buckhorn Asphalt Quarry contains the best-preserved Palaeozoic mollusc fauna in the world. Early impregnation of mixed siliciclastic–carbonate rocks (mudstones, pack to grainstones, shell beds, and conglomerates) with hydrocarbons prevented aragonite destruction (“Impregnation Fossil Lagerstätte”). The exceptional preservation com...

Paleontology is a small subject at universities. In Germany, there less than 50 professorships scattered across different locations. The fragmentation makes it difficult to develop common visions and research priorities. Over the last few decades, Paleontology has been transforming from a largely descriptive subject to a predictive science with und...

The Late Palaeozoic Ice Age (LPIA, Famennian to Wuchiapingian) witnessed two transitions between ice- and greenhouse conditions. These alternations led to drastic alterations in the marine system (e.g., sea-level, habitat size, sea-surface temperature) forcing faunal changes. To reassess the response of the global marine fauna, we analyze diversity...

The fossil-rich deposits from the Finis Shale (Graham Formation) at the "spillway section" near Jacksboro (North-Central Texas) are dated as early Virgilian (early Gzhelian; Late Pennsylvanian) in age. The Finis Shale is part of a cyclothem and represents the shallowing upwards sequence at this outcrop. The shale deposits are capped by phylloid alg...

The Late Paleozoic Ice Age (LPIA) was a phase of major climatic changes in Earth's history and serves as an analogue to today's conditions of globally increasing ocean temperatures, continuously melting ice caps, and rising sea-levels. Better understanding of the effects of the LPIA on macroevolutionary patterns can help in predicting the consequen...

The uppermost Pennsylvanian succession of North Central Texas is united as Cisco Group, each of the six formations included represents an almost complete megacycle of transgression and regression. The lowermost of these six cycles is known as the Graham Formation, with the Finis Shale, a complete second order cycle, near the base. The Finis Shale C...

The Late Paleozoic Ice Age (LPIA), a phase of major climatic changes, is commonly considered a phase of sluggish turnover rates. Using a large compilation of occurrence data, we re-assess turnover rates and diversity patterns of marine benthic taxa during the LPIA. We compare dynamics in the Paleozoic (here: brachiopods) and the modern evolutionary...

With 1429 animal species, the Triassic Cassian Formation in the Dolomites, Southern Alps (Italy), yields the highest species richness reported from any spatially constrained pre-Quaternary formation known to science. The high preserved diversity is partly attributable to a high primary diversity governed by the tropical setting, increasing alpha di...

Fossil groups are used for biochronological dating of rocks for decades. This manuscript presents a quantitative approach to appraise and compare the quality of selected taxa as biostratigraphic markers. Based on species occurrence of ammonites, bivalves, and planktic and benthic foraminifers we evaluate the potential of these to rank them quantita...

Many conservation lagerstätten feature excellent fossil preservation, but the environmental conditions responsible for the preservation, such as anoxia or hypersalinity, are often not favorable for highly diverse communities. Concentration lagerstätten contain abundant fossils that are commonly not well preserved, which inhibits taxon identificatio...
Article
The mid-Pennsylvanian (Desmoinesian–Virgilian) deposits from the Buckhorn Asphalt Quarry Lagerstätte near Sulphur, Oklahoma, are characterized by siliciclastic–carbonate rocks. One of these deposits is the ‘cephalopod coquina’ that contains a large amount of orthocerid and coiled nautiloid, and ammonoid shell remains. These were used for a detailed...

Many Palaeozoic reef environments were dominated by stromatoporoids and it has been proposed that skeletal mineralogy of such hypercalcifying reef builders mirrors the mineralogy of non-skeletal CaCO3 through time. However, the original skeletal composition of stromatoporoids is not well understood, with different authors arguing for an original co...

Bioerosion, i.e., chemical and mechanical degradation of largely carbonate skeletal material, was studied in detail in shells of Nautilus for the first time. Nautilus typically lives along slopes of coral reefs in water depths between 300-400 m, with a range of 100-700 m and occurs in the Indo-Pacific Ocean exclusively. After death of the animal it...

INTRODUCTION Deposits of the Pennsylvanian (Upper Carboniferous) Buckhorn Asphalt Quarry in southern Oklahoma, USA, are of mixed siliciclastic-carbonatic composition; however, crucial is the high content of hydrocarbons, that intruded the sediments during or only shortly after deposition. These hydrocarbons impregnated not only the deposits but mor...
