Megalosaurus

Megalosaurus (meaning "Great Lizard") is a genus of large meat-eating theropod dinosaurs of the Middle Jurassic period of Southern England. Although fossils from other areas have been assigned to the genus, the only certain remains of Megalosaurus come from the late Middle Jurassic of the Oxfordshire. The earliest possible fossils of the genus came from the Taynton Limestone Formation. One of these was

the lower part of a femur, discovered in the 17th century. It was originally described by Robert Plot as a thighbone of a Roman war elephant, and then as a biblical giant. The first scientific name given for it, in the 18th century, was Scrotum humanum, created by Richard Brookes as a caption; however, this is not considered valid today.
