Embasaurus (meaning "Emba lizard") is a genus of theropod dinosaur from the Early Cretaceous period. It is known from two vertebrae found in the Neocomian Sands of Kazakhstan. [2] [3] As it is known only from fragmentary remains, Embasaurus is considered by some to be a possible nomen dubium . It was named after the Emba River, and it is believed to have lived during the Berriasian stage, around 140 million years ago. According to the Theropod Database, a personal website designed by Mickey Mortimer, further research may suggest that Embasaurus may be a basal tyrannosauroid. [4] George Olshevsky, however, considered Embasaurus to be a megalosaurid, closely related to Magnosaurus , Megalosaurus , and Torvosaurus . [1]

The type species, Embasaurus minax, was described by the Soviet paleontologist Anatoly Riabinin in 1931. [4] [5]
