[11] [12] Large size appears to have evolved at least twice among dromaeosaurids; once among the dromaeosaurines Utahraptor and Achillobator, and again among the unenlagiines (Austroraptor, which measured 5–6 m (16–20 ft) long).

Dakotaraptor is exceptionally large for a dromaeosaurid, with an estimated adult length of 5.5 m (18 ft). [1] In 2016, other estimations suggested a length of 4.35-6 m (14.3-19.7 ft) and a weight of 220-350 kg (485-772 lbs). [10] [11] This approaches the size of one of the largest known dromaeosaurids, Utahraptor. [12]
Production on Jurassic Park began before the discovery of the large dromaeosaurid Utahraptor was made public in 1991, but as Jody Duncan wrote about this discovery: "Later, after we had designed and built the raptor, there was a discovery of a raptor skeleton in Utah, which they labeled 'super-slasher.' They had uncovered the largest ...
