Megalosaurinae

Nopcsa 1928

Les Megalosauridae sont un clade de dinosaures théropodes Tetanurae basaux ayant vécu du Jurassique moyen au Jurassique supérieur (Tithonien) sur l'ensemble des continents mis à part l'Océanie et l'Antarctique où leurs ossements n'ont pas encore été découverts. Les dernières études cladistiques qui ont été faites sur ces théropodes les rapprochent des Spinosauridae dont ils partagent la caractéristique anatomique d'avoir une griffe surdimensionnée au premier doigt de chaque main. Les membres les plus connus de ce clade sont le Megalosaurus découvert dans le Jurassique moyen (Bathonien) d'Angleterre et premier dinosaure à avoir été décrit et nommé dans la littérature scientifique, et Torvosaurus, dinosaure carnivore du Jurassique supérieur (Kimmeridgien-Tithonien) des États-Unis. Les Megalosauridae semblent avoir disparu à la limite Jurassique/Crétacé et semblent avoir été remplacés par d'autres théropodes au Crétacé inférieur, en témoigne l'absence totale de leurs restes au Crétacé.
