Abstract: | Chroniosuchians are basal tetrapods nesting within the paraphyletic anthracosaurs and were so far only well known from the
Permian and Triassic of Russia. In this study, we present evidence for their existence in the upper Middle Triassic of Germany,
based on diagnostic osteoderms and vertebrae from the Kupferzell and Vellberg localities in southern Germany. The finds are
most similar to Synesuchus, a Middle Triassic bystrowianid chroniosuchian from the Northern Ural Pechora region. They demonstrate that by Middle Triassic
time, chroniosuchians were much more widespread than previously thought. |
