Other dinosaurs that shared this environment with Suchosaurus included the iguanodontians Barilium and Hypselospinus, as well as the dubious species Megalosaurus dunkeri and an unnamed maniraptoran. They coexisted with the plesiosaur Hastanectes, the crocodyliform Goniopholis and the mammals Loxaulax, Aegialodon, Laolestes, and Spalacotherium.
