Diplodocus

The first skeleton of Diplodocus longus (Jurassic, 140 million years) was found in 1897 in Como Bluff, Wyoming. Fossil bones of this animal are common, except for the skull. The skull was very small compared to the huge size of the animal,which could reach up to 27 m. Instead of how Diplodocidae were always portrayed, with their necks high up in the air, it is now widely believed that the animal could only keep his head very low to the ground (for grazing), and that the very long tail served as a counterbalance for the long neck.
