The braincase of a small sauropod dinosaur (Reptilia: Saurischia) from the Upper Cretaceous Lameta Group, central India, with review of Lameta Group localities

The greater part of the braincase of a small sauropod dinosaur from the Upper Cretaceous Lameta Group near Dongargaon, Central India, is described. The braincase most closely resembles that of Antarctosaurus septentrionalis, the only other sauropod from the Lameta Group for which a substantial portion of braincase has been described. Differences between the two braincases are regarded as too great, however, to consider them as belonging to the same genus or species and the Dongargaon braincase is referred to the suborder Sauropoda as indeterminate. A variety of vertebrates, including fish, turtles, and dinosaurs, are now known from the Lameta Group near Dongargaon and the fauna as a whole is considered to be Santonian to Maastrichtian in age and to indicate a probable continental facies. A review of the Lameta Group localities of India is also given.
