The first two fingers had absurdly large unguals (claws); in Megaraptor the first claw was larger than the entire ulna. Unlike the large unguals of many ...
Biggest 'Megaraptor' Ever Discovered. If you've seen Jurassic Park, you know how scary velociraptors are -- and even if you haven't, they were dinosaurs with really sharp teeth, so that alone is ...
The fossils provide unique insights into an ancient Australian ecosystem dominated by powerful “megaraptor” dinosaurs measuring 6-7 metres in length. Two of the new megaraptor species are the ...

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.
