Fosterovenator (meaning "Foster's hunter") is a genus of ceratosaur dinosaur known from the Late Jurassic Morrison Formation of Wyoming. The holotype is YPM VP 058267A, B, and C, a tibia with an articulated astragalus. An additional specimen is known, the paratype YPM VP 058267D, a fibula of a larger individual.[1]
The holotype remains were discovered in 1879 by Arthur Lakes at Como Bluff, Wyoming, and consist of a nearly-complete right tibia with a co-ossified astragalus, probably of a juvenile. The paratype consists of a complete right fibula measuring 27.5 cm (10.8 in) in length and belonging to a much larger individual. The overall shape of the known material is similar to that of Elaphrosaurus.[1] However, ceratosaurian affinities of Fosterovenator (at least of the paratype) have been questioned.[2]
