Halszkaraptorinae

Cau et al. 2017

Halszkaraptorinae is an extinct basal ("primitive") subfamily of Dromaeosauridae that includes the enigmatic genera Halszkaraptor, Natovenator, Mahakala, and Hulsanpes. Halszkaraptorines are definitively known only from Late Cretaceous strata in Asia, specifically in Mongolia. It is debated among researchers whether the group had a semiaquatic lifestyle.
