Halszkaraptor (/ ˈ h ɑː l ʃ k ə r æ p t ər /; 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.

Sep 15, 2024 · Halszkaraptor was a small theropod with a distinctive body shape. Its head was approximately 2.8 inches long, set atop a neck that extended nearly 7.9 inches – effectively half the length of its body (not counting the tail).

Halszkaraptorinae is an extinct basal ("primitive") subfamily of Dromaeosauridae (or possibly Unenlagiidae) that includes the enigmatic genera Halszkaraptor, Natovenator, Mahakala, and Hulsanpes. Halszkaraptorines are definitively known only from Late Cretaceous strata in Asia, specifically in Mongolia.

Dec 8, 2017 · The new creature’s name— Halszkaraptor escuilliei —honors Escuillié for his role in discovering the fossil, and is a tribute to the Polish paleontologist Halszka Osmólska responsible for...

Halszkaraptor, although bizarre among paravians, possesses many features that can be traced back to more basal maniraptorans. It is therefore reinterpreted as a transitional form between non-paravian maniraptorans and more derived dromaeosaurids.

Sep 9, 2015 · Halszkaraptor is without doubt one of the most interesting dromaeosaurid dinosaurs ever discovered.‭ ‬Although a dromaeosaurid dinosaur,‭ ‬Halszkaraptor seems to have lived more like a modern day semi aquatic bird.‭

Nov 11, 2019 · Rather than being a semiaquatic piscavore, Halszkaraptor was a basal dromaeosaurid showing transitional features. The dinosaur lineage including birds and close relatives is known as the...

Jul 20, 2020 · That’s what happened when Halszkaraptor was announced in 2017: a duck-sized, long-necked, heavy-boned “raptor” dinosaur that may have lived in and around the water and hunted fish by diving and quickly extending its neck. Why do we think it was semi-aquatic?

Feb 25, 2020 · In Halszkaraptor, the platyrostral condition is acquired by the remarkable anteroposterior elongation and dorsoventral flattening of the prenarial region of the premaxilla, which also results in the posterior placement of the narial region relative to the snout anterior tip.

Dec 8, 2017 · The new dinosaur, named Halszkaraptor escuilliei, is a strange new anomaly in the dinosaur world. It walked on two legs on land, with postural adaptations similar to short-tailed birds (like ducks), but used its flipper-like forelimbs to maneuver in water (like penguins and other aquatic birds), relying on its long neck for foraging and ambush ...
