Tanystropheus longobardicus Silesaurus with an estimated age ofDuring the Middle Triassic, the coastal ecosystems of the supercontinent Pangaea hosted a diverse and, in many cases, morphologically unusual reptilian fauna. Prominent among these forms is Tanystropheus longobardicus , a basal archosauromorph whose unique anatomy has been the subject of extensive paleobiological and functional debate. This reptile is mainly characterized by an extremely elongated neck composed of disproportionately long cervical
