Dinosaur ancestor Postosuchus vertebra
Very nice Postosuchus trunk vertebra. Postosuchus was one of the largest carnivorous reptiles during the late Triassic. It was a member of the family of the archosaurs, the ancestors of modern crocodilians as well as the lineage that includes non-avian dinosaurs. Postosuchus lived in what is now North America during the Late Triassic. Where Postosuchus was a closer relative to crocodilians, he had very short forelimbs relative to the hind limbs, which suggest that he may have been committed to bipedal locomotion like later bipedal dinosaurs. Comes with a custom made stand.
