“These gut contents oddly represent the first recorded skeletal remains of ornithopods from the Winton Formation and may represent a new species.”ĭigital dissection of Confractosuchus sauroktonos in (a) dorsal aspect (c) ventral aspect (c) left lateral aspect (d) close-up of pectoral region with ventral osteoderms removed (in ventral aspect) (e) abdominal contents showing ornithopod remains. “Collectively, the ornithopod remains comprise three dorsal vertebrae, two sacral centra, three distal caudal centra, both proximal femora, left tibia, and several other elements all presumably from a single individual,” they said. The researchers also found the partly digested remains of a juvenile ornithopod dinosaur in the crocodile’s stomach. “The other, Isisfordia duncani, comprises multiple semi-articulated and partially complete skeletons.”

Matt White, a paleontologist with the Australian Age of Dinosaurs Museum of Natural History and the Palaeoscience Research Centre at the University of New England, and his colleagues. “ Confractosuchus sauroktonos represents only the second crocodyliform discovered from the Winton Formation,” said Dr. The animal’s fossilized remains - a near-complete skull with dentition and postcranial skeleton missing the tail and hind limbs - were discovered on Elderslie Station, near the north western margins of the Winton Formation, in 2010. It belonged to Eusuchia (literally, true crocodiles), a clade that includes living crocodilians and their closest relatives.

This list of ornithopod type specimens is a list of fossils serving as the official standard-bearers for inclusion in the species and genera of the dinosaur clade Ornithopoda, which includes the line of herbivorous dinosaurs culminating in the duck-billed hadrosaurs.
