Lewisauris

Lewisauris is a genus of small, extinct theropod dinosaurs discovered in the Late Cretaceous period. Fossils of Lewisauris have been found in North America. This genus is known from limited skeletal remains, primarily consisting of jaw fragments and some postcranial elements. Based on the available evidence, Lewisauris is estimated to have been a relatively small dinosaur, likely measuring around one to two meters in length. Its diet is believed to have been carnivorous, though specific details are not well understood due to the fragmentary nature of the fossils.

The classification of Lewisauris has been subject to some debate among paleontologists. It is generally placed within the Coelurosauria, a diverse group of theropod dinosaurs that includes birds. Some studies suggest it may be related to other small, agile theropods found in similar geological formations. The discovery of Lewisauris contributes to our understanding of the diversity of small predatory dinosaurs that inhabited North America during the final stages of the Mesozoic Era. Further fossil discoveries would be necessary to provide a more complete picture of Lewisauris' anatomy, behavior, and evolutionary relationships.
