Megalosauridae was a family of relatively primitive tetanuran theropod dinosaurs, order Saurischia. They were small-to-large carnivores with sharp teeth and three claws on each hand. Some members of this group were Megalosaurus, Eustreptospondylus and Torvosaurus. Megalosaurids first appear in the Middle Jurassic and seemed to have been displaced and replaced by other theropods by the Early Cretaceous; their fossils are known from Europe, North America, South America and Africa. They are considered by most researchers (Sereno 2005, Olshevsky 1995, Holtz 2004, etc.) to be close relatives of the spinosaurs.

- Megalosaurids were an advanced family within Megalosauroidea (though fairly primitive within Theropoda) that included medium- to large-sized theropods from the Mid- to Late Jurassic Period. They are close relatives of the Early & Late Cretaceous spinosaurids. Megalosauridae is one of the many theropod families split between the Wind and Fire Attributes.

| abstract
| - Megalosaurids were a family of tetanuran theropod dinosaurs, order Saurischia. They were small-to-large carnivores with sharp teeth and three claws on each hand. Some members of this group were Megalosaurus, Eustreptospondylus and Torvosaurus. Megalosaurids only lived in the mid-to-late Jurassic Period and have representatives found in Europe, North America, South America and Africa to date. They are considered by most researchers (Sereno 2005, Olshevsky 1995, Holtz 2004, etc.) to be close relatives of the spinosaurs. Like Megalosaurus itself, the family Megalosauridae, coined by Huxley in 1869, had traditionally been used as a 'wastebasket' group, which included a wide variety of unrelated species (such as Dryptosaurus, Ceratosaurus and Indosaurus). Because of this traditionally polyphyletic use, some scientists, such as Paul Sereno (2005), reject the family name Megalosauridae in favor of Torvosauridae (Jensen, 1985), despite the fact that Megalosauridae has priority under the ICZN rules governing family-level names in zoology. Similarly, Sereno and others reject the use of the superfamily name Megalosauroidea in favor of Spinosauroidea.
