Coelurosauravus (name meaning "Hollow Lizard") is a genus of basal diapsid reptile that originated during the Late Permian Era in what is now Madagascar. Small, gliding, lizard-like reptiles that resembled green iguanas or other modern-day lizards, the average length of the specimens was 40 centimeters (16 in) and the body was long and flat, suitable for gliding. It had specialized wing-like structures allowing it to glide, similarly to the modern-day Flying Dragon from South-east Asia.

In the episode "Desert Community Water Hole", a great number of Coelurosauravus was brought back to the park. However, due to their small size, they are one of the few creatures that roam freely around the park.


Era & DiscoveryEdit

Coelurosauravus lived in Madagascar during the Late Permian era, from 260–250 million years ago. Because of its small size, it was low on the food chain. It lived alongside creatures like Diictodon as well as Inostrancevia, Rhinesuchus, Scutosaurus.

Coelurosauravus was originally known from a single species, C. elivensis, which was named in 1926 based on fossils from the Sakamena Formation of Madagascar. Many other genera of weigeltisaurids have been lumped into Coelurosauravus since its original discovery.

Most notable of these was Weigeltisaurus jaekeli, originally described from Germany in 1930. This European species is now known from numerous specimens found in Germany (and one in England), of which some were very well preserved.

In 1987, Weigeltisaurus jaekeli was synonymized with Coelurosauravus as a second species, Coelurosauravus jaekeli. However, a 2015 study reinstated Weigeltisaurus as a separate genus for "Coelurosauravus" jaekeli.

Physical AttributesEdit

Coelurosauravus measured almost 2 feet in length (approximately the same size as a human arm but slightly larger) with a long, streamlined body resembling that of some modern lizards. Coelurosauravus' body possessed two large, wing-like structures, which allowed it to achieve powered flight and gliding around its environment in the air.

Due to the arid Permian climate of their home time, Coelurosauravus would be unused to the 21 Century's cooler, seasonal climate, and preferred high temperatures. Much like bats, they were dangerously vulnerable to freezing temperatures.

Behavior & TraitsEdit

Coelurosauravus appeared to live in small flocks together in their home time, although some of them could be more solitary or stray off. They also communicated with varying chirping vocalizations, and they apparently had an unusually long memory span for reptiles (over a year at least).
