The prenarial portion of the cranium of a slendersnouted phytosaur
(YPM VPPU 007920), with an associated osteoderm and bone fragments, was found by PEO, Bob Salvia and A.
participating in a summer paleontology field class with Mesalands Community College found a crocodile-like phytosaur
skull, which is approximately 220 million years old.
Already, Parker and his team have discovered the bones of an extinct, crocodile-like animal called Doswellia, previously known to exist in only Texas and Virginia; as well as the complete skull of a phytosaur
, another river-dwelling, crocodile-like carnivore.
They say about 1,400 skeletal elements have been recovered, including two skulls and a plethora of bones of the crocodile-like phytosaur
Redondasaurus and limb bones from a new form of a large, heavily armored aetosaur.
Permanent exhibits include casts of a Coelophysis and phytosaur
Previous field class participants have recovered numerous fossils in the field area, including two skulls of the crocodile-like phytosaur
Redondasaurus, armor plates and postcrania from a new heavily armored aetosaur, remains of a large predatory rauisuchian, and several hip and limb bones of one of the earliest dinosaurs.
In addition to the mastodon, other 'residents' of the gallery will include Coelophysis, Phytosaur
, Camarasaurus, Seymouria, Triassic specimens, Parasaurolophus T-Rex and Platybeladon.
It's not a dinosaur; it's a HUGE phytosaur
, bigger and meaner than today's crocodiles
Dawn of the Dinosaurs is a highly interactive, cutting edge exhibit hall of paleontology that features living fossils, the most complete database of research into Coelophysis, a wall of phytosaur
skulls and an interactive sculpture that allows visitors to explore the evidence scientists use to identify evolutionary trends.
Fossil vertebrates from this locality include metoposaurs, phytosaurs
, trilophosaurs, and pterosaurs, which are represented primarily by isolated teeth and jaw fragments.
Representing a broad range of depositional environments, ranging from perennial lacustrine to fluvial and aeolian settings, and documented by hundreds of fossils, these assemblages lack any of the characteristic Late Triassic faunal elements, most conspicuously metoposaurid temnospondyls, phytosaurs
, procolophonids, and diverse non-crocodylomorph and non-dinosaurian archosaurs, all of which are known from older assemblages in the Fundy basin and elsewhere.
Stretching along six miles of parkland (and extending as far as Utah), the huge formation contains remains dating back 220 million years, from crocodile-like phytosaurs
to armored, plant-eating aetosaurs.
