Predatory Dinosaurs of the World
Entrambi avevano furcule [altrimenti note come ossa dei desideri], covavano le uova, possedevano ossa cave ed erano ricoperti di piume. Se gli animali come Velociraptor fossero vivi al giorno d'oggi, la nostra prima impressione sarebbe semplicemente quella di uccelli dall'aspetto strano.
The more that we learn about these animals the more we find that there is basically no difference between birds and their closely related dinosaur ancestors like velociraptor. Both have wishbones, brooded their nests, possess hollow bones, and were covered in feathers. If animals like velociraptor were alive today our first impression would be that they were just very unusual looking birds.
