Eustreptospondylus oxoniensis, June 10, 2012:
Thursday, 26 December 2013
Eustreptospondylus is known from a single disarticulated skeleton of a juvenile or subadult from the marine deposits of the Middle Jurassic Oxford Clay of England. This medium size theropod is the best known megalosaurid from the northern hemisphere, and the second most complete theropod skeleton known from Western Europe (Baryonyx being first). The fact that it was discovered in marine sediments indicate that it may have been a coastal predator whose carcass was washed ashore. Although the estimated length of the juvenile skeleton is 4-5 meters, the adults were probably much larger.
