Description
Masillaraptorids have long legs, which may indicate they had a terrestrial lifestyle, foraging on the ground similar to modern caracaras. They have large pygostyles, suggesting they would have likely had long tail feathers. This, in addition to their long ulnae, suggests they were capable of well-developed flight. Their beaks are similar to those of extinct phorusrhacids and extant caracaras.[3]
