Rajasaurus cf. namadensis

Rajasaurus cf. namadensis

​

The chimera Lametasaurus from the Maastrichtian Lameta Formation in Jabalpur, India was split into several other dinosaurs during the 20th and 21rst centuries. The pelvis and isolated hindlimb bones in 2003 were suggested to belong to Rajasaurus based on similarities in the holotype. Among these was a large uncatalouged tibia around 58 cm long. This is significant as the alleged large size of the elements suggests a length of 9 meters and 2 tonnes. The problem is that the fossils were destroyed and never properly cataloged. That puts the titan Rajasaurus into question, as these elements can not be tested.

Big Brazilian Abelisaurid

The São Paulo Abelisaur (URC R-44) comes from the late Cretaceous Adamantina formation in Brazil. It mainly consists of a fragmentary right premaxilla, but it apparently came from a ginormous animal. Its skull was estimated to be about 120cm (based on Abelisaurus). If it had similar proportions, it would have been roughly over 10 meters long and potentially 3–5 tonnes. There are other possible giant abelisaurid elements from the same general area that also indicate animals of massive sizes. A fragmentary femur (75cm preserved) and isolated teeth (10cm) were described in 1913 but are now lost. Until more info is released, it's difficult to confirm such a size, but giant abelisaurs were clearly present there.
