Ceratosaurus, at first glance, looked like a fairly typical theropod, however its skull was quite large in proportion to the rest of its body and possessed a prominent nose horn formed from protuberances of the nasal bones.

In addition to the large nasal horn, Ceratosaurus possessed smaller hornlike ridges in front of each eye, similar to those of Allosaurus, these ridges were formed by enlargement of the lacrimal bones.

Marsh ( 1884 ) considered the nasal horn of Ceratosaurus to be a " most powerful weapon " for both offensive and defensive purposes, and Gilmore ( 1920 ) concurred with this analysis.

Rowe and Gauthier ( 1990 ) went further, suggesting that the nasal horn of Ceratosaurus was " probably used for display purposes alone " and played no role in physical confrontations.

A recent study by Robert Bakker suggested that Ceratosaurus generally hunted aquatic prey, such as fish and crocodiles, although it had potential for feeding on large dinosaurs.

This evidence is debatable, and Ceratosaurus tooth marks are very common on large, terrestrial dinosaur prey fossils.

Ceratosaurus is also featured in episodes of Jurassic Fight Club where it is seen as a rival to Allosaurus and preying on Stegosaurus.

There was a bony knob on its nose and multiple hornlets and ridges, similar to Ceratosaurus.

* Ceratosaurus nasicornis ( now on display at the Smithsonian ) is excavated in 1883, and later named and described by Marsh ( March 19, 1884 ).

Uniquely among theropods, Ceratosaurus possessed dermal armor, in the form of small osteoderms running down the middle of its back.

The classification of Ceratosaurus and its immediate relatives has been under intense debate recently.

While considered distant from birds among the theropods, Ceratosaurus and its kin were still very bird-like, and even had a more avian tarsus ( ankle joint ) than Allosaurus.

The holotype specimen of Ceratosaurus nasicornis, USMN 4735 was found with its left metatarsals II to IV fused together.

A Ceratosaurus battles a Triceratops in the 1966 remake of One Million Years B. C .. Ceratosaurus is also featured in The Land That Time Forgot ( 1975 ) where it battles a Triceratops, and its sequel The People That Time Forgot ( 1977 ) in which Patrick Wayne's character rescues a cavegirl from two pursuing Ceratosaurus by driving the dinosaurs off with smoke bombs ( after having failed to frighten them off by firing shots in the air once the Ceratosaurus attention had been shifted to Patrick Wayne's party of explorers ).

David B. Norman ( 1985 ) estimated that the maximum length of Ceratosaurus was.

Ceratosaurus reached lengths of 6 to 8 m ( 20 to 27 feet ), was around 2. 5 m ( 8 feet ) tall, and weighed between 500 kg and 1 tonne.

Some form of armor appears to have been necessary, as Stegosaurus species coexisted with large predatory theropod dinosaurs, such as Allosaurus and Ceratosaurus.

An assessment supported by a particularly large Ceratosaurus specimen from the Cleveland-Lloyd Quarry ( UMNH 5278 ), discovered in the mid-1960s, which may have been long assuming similar proportions to the holotype.

More recently, a Ceratosaurus made a brief appearance in the film Jurassic Park III in which it is repelled from attacking the main characters by a large mound of Spinosaurus dung.

* The T-Rex has three fingers and more closely resembles a large Ceratosaurus along with the Raptors.

Ceratosaurs are members of a group of theropod dinosaurs defined as all theropods sharing a more recent common ancestry with Ceratosaurus than with birds.

Marsh named the following dinosaur genera: Allosaurus ( 1877 ), Ammosaurus ( 1890 ), Anchisaurus ( 1885 ), Apatosaurus ( 1877 ), Atlantosaurus ( 1877 ), Barosaurus ( 1890 ), Camptosaurus ( 1885 ), Ceratops ( 1888 ), Ceratosaurus ( 1884 ), Claosaurus ( 1890 ), Coelurus ( 1879 ), Creosaurus ( 1878 ), Diplodocus ( 1878 ), Diracodon ( 1881 ), Dryosaurus ( 1894 ), Dryptosaurus ( 1877 ), Labrosaurus ( 1896 ), Laosaurus ( 1878 ), Nanosaurus ( 1877 ), Nodosaurus ( 1889 ), Ornithomimus ( 1890 ), Pleurocoelus ( 1891 ), Priconodon ( 1888 ), Stegosaurus ( 1877 ), Torosaurus ( 1891 ), Triceratops ( 1889 ).

This dinosaur also appears in the television documentary When Dinosaurs Roamed America, a Ceratosaurus makes a few appearances as a predator, killing Dryosaurus and eating it, a different one is shown chasing the same Dryosaurus but is later killed and eaten by an Allosaurus.

Ceratosaurus is known from the Cleveland Lloyd Dinosaur Quarry in central Utah and the Dry Mesa Quarry in Colorado.

The preserved fauna consists of almost all dinosaurs with the majority being carnivorous dinosaurs including Allosaurus ( material from at least 44 individuals make up almost 67 % of all remains ), Torvosaurus ( 1 ), Ceratosaurus ( 1 ), Stokesosaurus ( 2 ), Marshosaurus ( 2 ), and possibly an Ornitholestes.

The somewhat more advanced ceratosaurs ( including Ceratosaurus and Carnotaurus ) appeared during the Early Jurassic and continued through to the Late Jurassic in Laurasia.

According to the latest and most accepted theory, Ceratosauria includes the Late Jurassic to Late Cretaceous theropods Ceratosaurus, Elaphrosaurus, and Abelisaurus, found primarily ( though not exclusively ) in the Southern Hemisphere.

They examined a single foot bone referred to Ceratosaurus and found that it had a stress fracture.

Ceratosaurus is present in stratigraphic zones 2 and 4-6 of the Morrison Formation.

Ceratosaurus nasicornis skeleton restoration by O. C.

The type species, described by O. C. Marsh in 1884 and redescribed by Gilmore in 1920, is Ceratosaurus nasicornis.

Relatives of Ceratosaurus include Genyodectes, Elaphrosaurus, and the abelisaurs, such as Carnotaurus.

Ceratosaurus lived alongside dinosaurs such as Allosaurus, Torvosaurus, Apatosaurus, Diplodocus, and Stegosaurus.
