Lametasaurus (; ), is a chimeric genus of dinosaur known from the Lameta Formation of Jabalpur, India. The type species is L. indicus. The weight estimate of Lametasaurus, on the basis of the robust tibia, is , similar morphology can be seen in the tibia of Pycnonemosaurus, which indicates similar weight estimates.

==History of discovery== Between October 1917 and 1919 Charles Alfred Matley excavated fossils near Jabalpur. In 1921 he reported the find in the "Carnosaur Bed" of what he considered to be two megalosaurians, theropod dinosaurs. In 1923/1924 he named one of these as the type species Lametasaurus indicus. The generic name refers to the Lameta Formation, dating from the Maastrichtian, the specific name refers to India. However, Matley no longer identified it as a theropod but as a member of the Stegosauria instead, which concept at the time also included the armoured dinosaurs today assigned to the Ankylosauria; at first Matley had seen it as a stegosaurian in the modern sense and even intended to name it as a species of Omosaurus. The type specimen consisted of a number of dermal scutes, a sacrum of at least five sacral vertebrae( in length), a pair of ilium(left ilium is in length with the acetabular portion, including the pubic and ischial processes, being about long and wide), a tibia( cm long with the distal breadth being ) and teeth. In 1933 Matley and Friedrich von Huene described some more remains collected by Barnum Brown, thought to have been part of a tail club; later this was shown to be a large osteoderm.
