Named By: S. J. Nesbitt, R. B. Irmis, S. G. Lucas & A. P. Hunt - 2005.
Classification: Chordata, Reptilia, Crocodylomorpha, Sphenosuchidae.
Species: R. quayensis (type).
Size: Skull at least 60 centimetres long. Total length about 3.8-4 meters long.
Known locations: USA, New Mexico - Redonda Formation.
Time period: Norian/Rhaetian of the Triassic.
Fossil representation: Partial skull and partial post cranial skeletal fossils.
is a genus of sphenosuchid crocodylomorph that lived in the USA during
the later stages of the Triassic. Only the anterior (forward)
portion of the skull is known, though estimates of the complete
skull result in a reconstructed length of at least sixty centimetres,
and when combined with the post cranial remains, result in a total
estimated length of just under four meters. Redondavenator
been a predator of other relatively large animals, with speculation
that the genus may have evolved to fill an ecological niche left vacant
and not yet filled by dinosaurs.
Care should be taken not to confuse Redondavenator with Redondasaurus, a large phytosaur that is also named after the Redonda Formation like Redondavenator also is.
