This is Peteinosaurus. A flying reptile that has evolved extra-long fingers to support their delicate wing membrane.
— Allen, about Peteinosaurus

Peteinosaurus (name meaning "Winged Lizard") is a genus of basal pterosaur that originated during the Middle to Late Triassic period in what is now North America and southern Europe. Though only a foot wide of a wingspan, this was one of the very earliest pterosaurs.

In the Series 2 premiere "Birth of a New Blood", a flock of Peteinosaurus were brought back to the park from Late Triassic Arizona 225 million years ago. Due to their small size, they are one of the few animals that are allowed to roam free.


Era & DiscoveryEdit

Peteinosaurus lived during the Late Triassic period, 225-208 million years ago, making it the first pterosaur ever to evolve. By the time they took to the skies, flying reptiles were becoming new masters of the skies. However, by the end of the Triassic, Peteinosaurus vanished from the face of the Earth, having been replaced by other pterosaurs, such as Anurognathus. Peteinosaurus was first discovered in 1978.

Physical AttributesEdit

Peteinosaurus was a comparatively small pterosaur of the characteristic long-tailed Rhamphorhynchids, at around 40-60 cm (1-2 ft) in wingspan. Its diet would have consisted largely of insects, such as Dragonflies, due to its tiny but very sharp needle-like teeth.

A small, primitive member of the Pterosaur family, Peteinosaurus were flying reptiles that evolved extra-long fingers to support their delicate wing membranes. A jaw full of needle-sharp teeth make short of their insect prey. Petienosaurus evolved strong, lightweight bones for flight and, like the dinosaurs, they were fast and deadly.

Behavior & TraitsEdit

A small species of Pterosaur, Peteinosaurus often lived by the beach sides and also up in trees close to rivers, especially in large numbers. They also scavenged off of dead and dying larger animals but only hunted insects, like dragonflies. When they risk a cooling bath in water, the constantly check for danger.
