Tambatitanis

Tambatitanis (meaning "Tamba giant", after Tamba, the name given to the northwest of Kansai, Japan ) is an extinct genus of titanosauriform dinosaur from the Early Cretaceous (probably early Albian ) of Japan. It is known from a single type species, Tambatitanis amicitiae, which is known from the Sasayama Group. It was probably around 14 m long and its mass was estimated at some 4 t. It was a basal titanosauriform and possibly belonged to the Euhelopodidae. The holotype was collected between 2006 and 2010.
