Allosaurus was a biped with three pointed toes on each foot, and each toe had a claw on the end. Virtually any bird has a very similar footprint. Thus, the footprints of Allosaurus and other theropod dinosaurs look like giant chicken tracks.
Chicken
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.

Allosaurus is the most common meat eating dinosaur fossil in the areas where it lived. Sometimes an animal's lifestyle makes it disproportionately likely or unlikely to fossilize, but since Allosaurus is so common in the fossil record, they were probably relatively common when they existed.
