Upper Cretaceous, 70 mya
|Balaur bondoc displaying its double |
sickle claws in a kicking action
The specimen is unique: unlike most other dromaeosaurs, it had two sickle claws on each foot, not just one. It had a reduced and presumably nonfunctional third finger, consisting of only one rudimentary phalanx.
The specimen was discovered in 2010. Balaur lived on a large prehistoric island called Hateg Island. Seventy million years ago, sea levels were much higher than they are today. Europe was an archipelago of islands.
