Utahraptor was one of, if not the largest and heaviest of all dromaeosaurids, with the largest assigned specimen BYUVP 15465 having a femoral length of 56.5–60 cm (22.2–23.6 in). [8] [9] Utahraptor is estimated to have reached 6–7 metres (20–23 ft) in length and somewhat less than 500 kg (1,100 lb), comparable in weight to a polar bear.

Unenlagia (meaning "half-bird" in Latinized Mapudungun) is a genus of dromaeosaurid theropod dinosaur that lived in South America during the Late Cretaceous period. [1] The genus Unenlagia has been assigned two species: U. comahuensis, the type species described by Novas and Puerta in 1997, [1] and U. paynemili, described by Calvo et al. in 2004.

As a result, they portrayed the film's dinosaurs with the size, proportions, and snout shape of Deinonychus. [2] The 20-foot-long (6.1 m) Utahraptor is commonly considered to be a close match to the film's dinosaurs, which are much larger than either Deinonychus or Velociraptor were in life. [82] [83]
