Researchers identified the creatures by their “degenerated” color and “extremely long” beak, according to a study.
About 31 to 41 serrations were on the front edges, and 29 to 33 were on the back. At least the second and third teeth of the premaxilla had serrations, but the fourth tooth did not. The teeth were covered in a thin layer of enamel, 0.1 to 0.15 mm (0.0039 to 0.0059 in) thick, which extended far towards their bases. The alveoli were elliptical to ...

The hand claws of Megaraptor were very long and strongly curved, with the claw of the first finger measuring 35 cm (14 in). The claw of the third finger was the smallest, only 6.5 cm ...
