What are preadators of the ammosaurus?

Ammosaurus, a genus of dinosaur from the Late Jurassic period, likely faced predation from larger carnivorous dinosaurs of its time, such as Allosaurus and Ceratosaurus. Additionally, smaller theropods could have posed a threat to juvenile ammosaurus. Environmental factors and competition for resources could also have influenced its survival. However, specific evidence about its predators is limited due to the fossil record.
