This is the anterior end of the left dentary (lower jaw) of Ceratosaurus.It has two beautifully preserved teeth exposed showing the taxonomically characteristic, longitudinal grooves along the inner surfaces. Ceratosaurus is a rare, predatory dinosaur of the late Jurassic Period. There is only one of these flesh-eaters in the Cleveland-Lloyd Quarry; however, at least five others are known from various Morrison Formation exposures in the Colorado Plateau and Wyoming. Ceratosaurus is also known from the Tendaguru beds of Tanzania in east Africa.
