One classification subdivides the group into the Spinosauroidea and Avetheropoda, the latter consisting of the Carnosauria (allosaurs and their close relatives; allosaurids flourished from the late Jurassic to the late Cretaceous period, in places as far apart as North and South America, Europe and Africa) and the Coelurosauria.
