Fukuiraptor ("thief of Fukui") was a medium-sized carnivore of the Early Cretaceous (Barremian) that lived in what is now Japan. Scientists first thought it was a member of the Dromaeosauridae, but after studying the fossils they then believed it was related to Allosaurus (which is classed in a different family) in the family Neovenatoridae.[1] However, more recently, another analysis has proposed that all megaraptorans are actually tyrannosauroids, which would reclassify Fukuiraptor as a tyrannosauroid coelurosaur.[2]

The type specimen is the skeleton of an individual about 4.2 metres long. It is thought that this specimen was not mature and an adult may have been larger. However, the other individuals recovered from the same locality are all juveniles that were smaller than the holotype (Currie & Azuma, 2006), in the smallest case less than a quarter of the holotype's size.
