Halszkaraptor (/ˈhɑːlʃkəræptər/; meaning "Halszka's seizer") is a genus of waterfowl-like dromaeosaurid dinosaurs from Mongolia that lived during the Late Cretaceous period. It contains only one known species, Halszkaraptor escuilliei. The type specimen (holotype) has been compared to the bones of extant crocodilians and aquatic birds, and found evidence of a semiaquatic lifestyle,[1] while some researchers question about semiaquatic ecology.[2][3] A phylogenetic analysis revealed it was a member of the basal subfamily Halszkaraptorinae, along with Mahakala and Hulsanpes.
