Fun facts

Fukuititan was named in 2010 by scientists Yoichi Azuma and Masateru Shibata, who worked at the Fukui Prefectural Dinosaur Museum.1

The only known fossil of Fukuititan was found in an area of 150 square metres, and all the bones are thought to belong to one animal.1

Fukuititan had a stalk-like epipophysis on its neck vertebrae, a feature that helps tell it apart from other titanosauriforms.1

Its teeth had an elongated crown with a weak or absent labial groove, and no lingual concavity.3

Fukuititan is the first relatively complete titanosauriform skeleton found in Japan.3

Some scientists think the holotype specimen was an immature individual, so its adult size is uncertain.1
