Streptospondylus

Streptospondylus (meaning "reversed vertebra") is a genus of tetanuran theropod dinosaur known from the Middle Jurassic period of France, 161 million years ago. It was a medium-sized predator.

Discovery and naming
Streptospondylus was one of the first dinosaurs collected and is the first described, though not named. From about 1770, a certain abbey Bachelet, an amateur naturalistliving in Rouen, began to collect fossils. These included some theropod vertebrae and limb elements found near Honfleur. In 1776 abbey Jean-François Dicquemare working in Le Havre reported some similar bones, interpreted by him as the remains of dolphins and porpoises.
