Extending the footprint record of Pareiasauromorpha to the Cisuralian: earlier appearance and wider palaeobiogeography of the group

Lorenzo Marchetti, Sebastian Voigt, Eudald Mujal, Spencer Lucas, Heitor Francischini, Josep Fortuny & Vincent Santucci
Pareiasauromorpha is one of the most important tetrapod groups of the Permian. Skeletal evidence suggests a late Kungurian origin in North America, whereas the majority of occurrences come from the Guadalupian and Lopingian of South Africa and Russia. Pareiasauromorpha footprints include the ichnogenus Pachypes, that is, however, unknown from strata older than late Guadalupian. A revision of several Pachypes-like footprints from the Cisuralian–Guadalupian of Europe and North America confirm the occurrence of this ichnogenus and...

Data from: A new dissorophoid temnospondyl from the Allegheny Group (Late Westphalian, Carboniferous) of Five Points, Mahoning County, Ohio (USA)

Rainer Schoch, Amy Henrici & Robert Hook
A small temnospondyl skull from the Upper Carboniferous Allegheny Group of Five Points, Ohio, is referred to a new dissorophoid, Palodromeus bairdi n. gen n. sp. The complete skull with mandibles is preserved in counterparts. It is characterized by (1) elongated slit-like choana, (2) postfrontal, postorbital, and supratemporal bearing a distinct ridge, and (3) reduced parietal only two-thirds the length of the frontal. Phylogenetic analysis confirms a dichotomy between amphibamiforms and olsoniforms and places Palodromeus...

A tiny new Middle Triassic stem-lepidosauromorph from Germany: implications for the early evolution of lepidosauromorphs and the Vellberg fauna

Gabriela Sobral, Tiago R. Simões & Rainer R. Schoch
The Middle Triassic was a time of major changes in tetrapod faunas worldwide, but the fossil record for this interval is largely obscure for terrestrial faunas. This poses a severe limitation to our understanding on the earliest stages of the diversification of lineages representing some of the most diverse faunas in the world today, such as lepidosauromorphs (e.g., lizards and tuataras). Here, we report a tiny new lepidosauromorph from the Middle Triassic from Vellberg (Germany),...
