Datos curiosos
Kaijutitan is the latest known basal titanosaur, meaning it lived near the end of the time when early titanosaurs existed.2
Its neck vertebrae had bifid (split) neural spines, a feature that evolved several times among sauropods but is rare in titanosaurs.2
The fossil includes part of the skull, which is very unusual for large titanosaurs because their skulls are rarely preserved.2
Kaijutitan lived about 89 to 86 million years ago, during the Coniacian stage of the Late Cretaceous.4
Its bones were found scattered in an area of about 20 square metres, suggesting the carcass fell apart before being buried.2
The species name maui honors the Museo Municipal Argentino Urquiza (MAU), where the fossil is stored.1
