Isisaurus
The type specimen of "Isisaurus colberti", ISI R 335/1-65, was originally described and named as "Titanosaurus colberti" by Sohan Lal Jain and Saswati Bandyopadhyay in 1997, the specific name honouring Edwin Harris Colbert, but was placed in its own genus, by Wilson and Upchurch, in 2003. It had a short, vertically directed neck and long forelimbs, making it considerably different from other sauropods. The humerus is 148 centimetres long. Based on this specimen, "Isisaurus" would have grown to about 18 meters (60 feet) in length and weighed about 14,000 kg (15 tons).
