Masillaraptoridae is an extinct family of stem-group falconiform birds from the Eocene of Europe.

Two genera have been named: Danielsraptor, from the London Clay of England, and Masillaraptor, from Messel Pit in Germany.

[1][2][3] Masillaraptorids had long legs, which may indicate that they had a terrestrial lifestyle, foraging on the ground similar to modern caracaras.

This, in addition to their long ulnae, suggest that they were capable of well-developed flight.
