is the first ever sauropod
dinosaur known to have lived in what is now
Japan. The holotype individual of Fukuititan
seems to have been
fairly small in terms of overall sauropod sizes, and may be a
reflection of living upon a smaller land mass. Based upon similarity
between the caudal (tail) vertebrae, Fukuititan
considered as possibly being related to Borealosaurus
which in turn has been considered as a potential relative of
Fukuititan translates as ‘Fukui titan’ a combination of being named after Fukui prefecture and the Ancient Greek titan which is commonly used for naming sauropod dinosaurs of the titanosaurid lineage. The species name nipponensis more simply means ‘from Japan’. Fukuititan likely shared the same habitat as other dinosaurs such as the hadrosaur Fukuisaurus and the megaraptoran theropod Fukuiraptor, while remains of Psittacosaurus also seem to be within the formation. Aside from these more derived fossils, indeterminate fossils of dromaeosaurs, other sauropods and ornithopod dinosaurs are also known, as well as dinosaur eggs and track ways of various kinds of dinosaurs.
