North America, Morrison Formation
The Late Jurassic was the age of giant long-necked dinosaurs, and none is perhaps better known than the sauropod Diplodocus, a surprisingly gracile member of a family which produced many of the largest land animals that ever lived
Diplodocus carnegii pictured here grew to lengths of twenty five metres and probably browsed on ferns, cycads and bennettitales that grew along the forest margins. It shared its world with many other classic dinosaurs including Apatosaurus, Stegosaurus, Camarasaurus and the formidable carnivore Allosaurus.
The discovery in 1990 of partial skin impressions of an undescribed diplodocid from the Morrison formation would seem to indicate this dinosaur may have possessed a row of short keratinous spines along all or part of its tail and back.
