“Lightweight Lizard” discovered in 1920 by Janensch. It was around 6 meters (20ft.) in length and less than 250kg in weight (like its name means it was light built). Lived during Late Cretaceous Period, around 145 million years ago in Tanzania. Elaphrosaurus is only known from a single nearly complete skeleton and no skull had ever been found.
An Elaphrosaur is seen on Isla Nublar, chasing Derek and Abby’s jeep. However, The humans fire a flare gun at the animal, which causes it to break off it’s pursuit.
