Masillaraptoridae is an extinct family of stem-group falconiform birds from the Eocene of Europe. They are noted for their relatively long legs. Two genera have been named: Danielsraptor, from the London Clay of England, and Masillaraptor, from Messel Pit in Germany.{{Cite journal |last=Mayr |first=Gerald |date=January 2006 |title=A new raptorial bird from the Middle Eocene of Messel, Germany |url=http://www.tandfonline.com/doi/abs/10.1080/08912960600640762 |journal=Historical Biology |language=en |volume=18 |issue=2 |pages=99–106 |doi=10.1080/08912960600640762 |bibcode=2006HBio...18...99M |s2cid=34895565 |issn=0891-2963|url-access=subscription }}{{Cite journal |last=Mayr |first=Gerald |date=2009-05-20 |title=A well-preserved second trogon skeleton (Aves, Trogonidae) from the middle Eocene of Messel, Germany |url=http://dx.doi.org/10.1007/s12549-009-0001-9 |journal=Palaeobiodiversity and Palaeoenvironments |volume=89 |issue=1–2 |pages=1–6 |doi=10.1007/s12549-009-0001-9 |bibcode=2009PdPe...89....1M |s2cid=73722121 |issn=1867-1594|url-access=subscription }}{{Cite journal |last1=Mayr |first1=Gerald |last2=Kitchener |first2=Andrew C. |date=2022-07-08 |title=New fossils from the London Clay show that the Eocene Masillaraptoridae are stem group representatives of falcons (Aves, Falconiformes) |journal=Journal of Vertebrate Paleontology |volume=41 |issue=6 |language=en |pages=e2083515 |doi=10.1080/02724634.2021.2083515 |s2cid=250402777 |issn=0272-4634|doi-access=free }}
