Dimetrodon, which lived before dinosaurs, which includes Triceratops and Allosaurus,
had even existed.
No descendants of Allosaurus exist today. However, birds evolved from other carnivorous dinosaurs, which were relatives of Allosaurus. Thus, the closest living relatives of Allosaurus are birds. All birds are equally related to Allosaurus.
Dimetrodon was a mammal-like reptile that lived during the Permian period, which was before the dinosaurs came. It had a large saill on its back, probably to warm its body up. It walked on 4 legs and hd a tail.
Probably the allosaur Allosaurus Fragilis, becuase of its lighter build. Allosaurs came in many sizes, some as big as T Rex.
Triceratops didn't have anything on its back. However, it did have a large round frill that came off the back of its head and covered its neck.
