The heaviest Dromaeosaurids / dromaeosaurs – Top 10

Weight, dimensions, size of raptors (Dromaeosaurids / dromaeosaurs)

The Dromaeosauridae are a family of theropod dinosaurs. They were small to medium-sized, two-legged carnivores that were probably closely related to the birds (Aves). These feathered dinosaurs were characterized by a narrow muzzle, long arms reinforced with curved claws, a stiffened tail and an enlarged crescent-shaped claw on the foot.

Dromaeosaurids were small to medium-sized animals. The size ranged from 47 to 63 centimeters (1.5 – 2.1 ft) in length and 200 to 600 grams in weight with Microraptor zhaoianus to over six meters in length with Achillobator and Utahraptor. According to studies by paleontologists led by Alan H. Turner, the generally small body dimensions of the basal species, i.e. those at the beginning of the development line, suggest that the common ancestor of all dromaeosaurids was only about 65 centimeters (2.1 ft) long and 700 grams heavy.

Raptors are well-known dinosaurs from the movies titled Jurassic Park and Jurassic World.

Today we present the world’s largest list of raptors (Dromaeosaurids) ranked by weight. Soon we will present a list of the longest raptors (dromaeosaurs).
