 Halszkaraptorinae

Halszkaraptorinae is a basal ("primitive") subfamily of Dromaeosauridae that includes the enigmatic genera "Halszkaraptor", "Mahakala", and "Hulsanpes".A comparison of the fossils of "Halszkaraptor" with the bones of extant crocodilians and aquatic birds revealed evidence of a semiaquatic lifestyle.
