Elaphrosaurus (Lightweight lizard)
Werner Janensch - 1920
Estimated 6.2 meters long
E. bambergi (type)
Tanzania - Tendaguru Formation. Possibly also USA - Morrison Formation
Late Jurassic, 154-150 million years ago
Elaphrosaurus, meaning “lightweight lizard,” is a genus of theropod dinosaur that lived during the Late Jurassic period, approximately 154 to 150 million years ago, in what is now Tanzania.
Elaphrosaurus was a relatively small and lightweight theropod dinosaur, with a long neck and tail, and slender, agile legs. Its overall body plan suggests that it was a fast runner and a highly active predator, likely feeding on small to medium-sized animals.
The discovery of Elaphrosaurus has provided important insights into the diversity and evolution of theropod dinosaurs during the Late Jurassic period, a time when many of the major groups of dinosaurs were evolving and diversifying. Its physical characteristics suggest that it was a highly specialized and successful species, adapted to its environment and ecological niche.
Despite its importance, relatively few fossils of Elaphrosaurus have been found, making it a relatively poorly known dinosaur. Nonetheless, it remains a fascinating and important species for scientists and dinosaur enthusiasts alike, offering important clues into the complex ecosystems and evolutionary processes of the Late Jurassic period in Africa.
