Rahiolisaurus is a genus of abelisaurid theropod dinosaur which existed in India during the Late Cretaceous period. It was described in 2010, based on fossils recovered from the Lameta Formation in the Indian state of Gujarat. These fossils include elements from at least seven different individuals and are believed to have been from the Maastrichtian stage, sometime between 72.1 and 66 million years ago. Despite representing a variety of different growth stages, all recovered fossils from the locality indicate a single type species, Rahiolisaurus gujaratensis.
Rahiolisaurus was initially described as a large-sized abelisaurid and around 8 m (26.2 ft) long,[1] although the specimen (ISIR 557) that this estimate was based on was later estimated to be 6.3 metres (20.7 ft) in length.[2] It shares many similarities with another Indian abelisaurid, Rajasaurus, but includes differences such as an overall more gracile and slender-limbed form.[1]
