True to some degree, but I wouldn't call them fully functional. They would have been more like semi-mobile grappling hooks. Mmh... I'm not really convinced about that; if i look at the hand of a typical derived dromeosaurid like Deinonychus, Velociraptor and such, i see well-developed fingers, robust claws and other elements which suggest me that in life it was quite, ehr, dexterous (not as a monkey like us, obviously, but more like a parrot or any other bird who uses his feet like they'd be hands). There is a good chance their fingers were fused together I think. |

Certainly not as dexterous as a parrot foot. Parrots have a reversed hallux which is opposable to the other digits and so it's good at grasping. The only dromaeosaurid known to have had a semi-opposable digit is Bambiraptor. www.tandfonline.com/doi/abs/10.1671/0272-4634%282006%2926%5B897%3ACOFFBD%5D2.0.CO%3B2 |
