By contrast, troodontids evolved a longer metatarsus for speed and a more precise, but weaker grip, suggesting they were swift but probably took relatively smaller prey."
"Dromaeosaurids evolved towards stronger, slower feet, suggesting a stealthy ambush predatory strategy, adapted for relatively large prey. "Troodontids and dromaeosaurids started out looking very similar, but over about 60 million years, they evolved in opposite directions, adapting to different niches," said Fowler. Such behavior intriguingly contrasts with that of their closest known relatives, a very similar group of small carnivorous dinosaurs called troodontids. " Velociraptor and Deinonychus also have a very short, stout metatarsus, suggesting that they had great strength but wouldn't have been very fast runners." "When we look at modern birds of prey, a relatively short metatarsus is one feature that gives the bird additional strength in its feet," Fowler said. Fowler)Īll in all, Velociraptor and its kin do not seem adapted to simply running after prey. Deinonychus (C) has an unusually long outer toe and a short inner toe, more suitable for grasping. Dinos adapted for running and walking tend to have a large middle toe with side toes that are shorter and about equal in length, like A ( Gallimimus) and B ( Allosaurus). Dinosaur feet are adapted for different purposes.
