Did You Know? 17 Incredible Lewisuchus Facts


Share this article

Lewisuchus Admixtus is a prime example of a silesaurid dinosauriform.

The Lewisuchus belongs to a family of early archosaurs that are a sister group of the dinosaurs. The fossil of the Lewisuchus was recovered from the Chanares Formation in Argentina.

The first fossil specimen of this creature from Argentina consisted of only a partial skull while the new specimens consisted of cranial bones, a femur, and lower forelimbs. Finding this creature was one of the amazing discoveries that could lead to more answers about the origin of dinosaurs and about the evolution of dinosaurs.

What was the Lewisuchus' habitat?

Not much is known about the world of the Lewisuchus, however, most of the land in Pangaea near oceanic bodies during the Upper Triassic and Late Triassic Period consisted of alluvial plains. The locality and strata of La Rioja Province in Argentina where the specimen samples have been uncovered also show signs of being near the ocean.

An unnamed skull of Lewisuchus was once mistaken to be a part of the fossil specimen of another Late Triassic archosaur but later evidence showed the matrix to contain two taxa.
