You thought Tyrannosaurus Rex had tiny arms? Well, T. Rex looked like Stretch Armstrong next to Carnotaurus, which possessed such puny front limbs its forearms were only one-quarter the length of its upper arms that it may as well have had no forelimbs at all.

One of the most distinctive things about Carnotaurus is where this dinosaur lived: South America, which was hardly well-represented in the giant theropod department during the late Cretaceous period about 70 million years ago.

Oddly enough, the largest-ever South American theropod, Giganotosaurus , lived a full 30 million years earlier; by the time Carnotaurus came on the scene, most of the meat-eating dinosaurs in South America only weighed a few hundred pounds or less.

During the Mesozoic Era, the vast majority of horned dinosaurs were ceratopsians : the plant-eating behemoths exemplified by Triceratops and Pentaceratops.

To date, Carnotaurus is the only meat-eating dinosaur known to have possessed horns, six-inch protrusions of bone atop its eyes that may have supported even longer structures made of keratin the same protein that comprises human fingernails.

These horns were likely a sexually selected characteristic, wielded by Carnotaurus males in intra-species combat for the right to mate with females.

Not only is Carnotaurus represented in the fossil record by a single, nearly complete skeleton; paleontologists have also recovered fossil impressions of this dinosaur's skin, which was somewhat surprisingly scaly and reptilian.

We say "somewhat surprisingly" because many theropods of the late Cretaceous period possessed feathers, and even T.

Carnotaurus was a lightly built, bipedal predator, measuring 7. As a theropod, Carnotaurus was highly specialized and distinctive.

It had thick horns above the eyes, a feature unseen in all other carnivorous dinosaurs, and a very deep skull sitting on a muscular neck.

Carnotaurus was further characterized by small, vestigial forelimbs and long, slender hindlimbs. The mosaic was interrupted by large bumps that lined the sides of the animal, and there are no hints of feathers.

The distinctive horns and the muscular neck may have been used in fighting conspecifics. According to separate studies, rivaling individuals may have combated each other with quick head blows, by slow pushes with the upper sides of their skulls, or by ramming each other head-on, using their horns as shock absorbers.

The feeding habits of Carnotaurus remain unclear: some studies suggest the animal was able to hunt down very large prey such as sauropods , while other studies find it preyed mainly on relatively small animals.

Carnotaurus was well adapted for running and was possibly one of the fastest large theropods. Carnotaurus was a large but lightly built predator.

Carnotaurus was a highly specialized theropod , as seen especially in characteristics of the skull , the vertebrae and the forelimbs.

Both the pelvis and hindlimb bones were long and slender. The skull, measuring The teeth were long and slender, [13] as opposed to the usually very short teeth seen in other abelisaurids.

These slender bones, supporting the tongue musculature and several other muscles, are rarely found in dinosaurs because they are not connected to other bones and therefore get lost easily.

The vertebral column consisted of ten cervical neck , twelve dorsal , six fused sacral [Y] and an unknown number of caudal tail vertebrae.

These processes were the highest points of the spine, towering above the unusually low spinous processes. The end of each caudal rib was furnished with a forward projecting hook-shaped expansion that connected to the caudal rib of the preceding vertebra.

The forelimbs were proportionally shorter than in any other large carnivorous dinosaurs, including Tyrannosaurus.

There were no carpalia in the hand, so that the metacarpals articulated directly with the forearm. The fingers themselves were fused and immobile, and may have lacked claws.

Carnotaurus was the first theropod dinosaur discovered with a significant number of fossil skin impressions.

Still, the surface texture of much of the right side of the skull is very different from that of the left side, and probably shows some features of the scalation pattern of the head.

This mosaic was divided by thin, parallel grooves. The bumps probably represent clusters of condensed scutes , similar to those seen on the soft frill running along the body midline in hadrosaurid "duck-billed" dinosaurs.

Carnotaurus is one of the best-understood genera of the Abelisauridae , a family of large theropods restricted to the ancient southern supercontinent Gondwana.

Abelisaurids were the dominant predators in the Late Cretaceous of Gondwana, replacing the carcharodontosaurids and occupying the ecological niche filled by the tyrannosaurids in the northern continents.

Though relationships within the Abelisauridae are debated, Carnotaurus is consistently shown to be one of the most derived members of the family by cladistical analyses.

Carnotaurus is eponymous for two subgroups of the Abelisauridae: the Carnotaurinae and the Carnotaurini. Paleontologists do not universally accept these groups.

The Carnotaurinae was defined to include all derived abelisaurids with the exclusion of Abelisaurus , which is considered a basal member in most studies.

Below is a cladogram published by Canale and colleagues in As a result, the upward curvature of the upper jaw is artificially exaggerated in the holotype.

This sculpture, ordered by the museum during the mids, is probably the first life restoration of a theropod showing accurate skin.

Originally, the rocks in which Carnotaurus was found were assigned to the upper part of the Gorro Frigio Formation , which was considered to be approximately million years old Albian or Cenomanian stage.

Carnotaurus is the only known carnivorous bipedal animal with a pair of horns on the frontal bone. Greg Paul proposed that the horns were butting weapons and that the small orbita would have minimized the possibility of hurting the eyes while fighting.

They calculated that the neck musculature was strong enough to absorb the force of two individuals colliding with their heads frontally at a speed of 5.

He also noted an enhanced rigidity and strength of the spinal column that may have evolved to withstand shocks conducted by the head and neck.

Other studies suggest that rivaling Carnotaurus did not deliver rapid head blows, but pushed slowly against each other with the upper sides of their skulls.

Gerardo Mazzetta and colleagues propose that the horns might also have been used to injure or kill small prey. Though horn cores are blunt, they may have had a similar form to modern bovid horns if there was a keratinous covering.

However, this would be the only reported example of horns being used as hunting weapons in animals. Analysis of the jaw structure of Carnotaurus by Mazzetta and colleagues , , suggests that the animal was capable of quick bites, but not strong ones.

Elasticity of the jaw would have allowed Carnotaurus to swallow small prey items whole. In addition, the front part of the lower jaw was hinged, and thus able to move up and down.

When pressed downwards, the teeth would have projected forward, allowing Carnotaurus to spike small prey items; when the teeth were curved upwards, the now backward projecting teeth would have hindered the caught prey from escaping.

These researchers also noted analogies with modern Komodo dragons : the flexural strength of the lower jaw decreases towards the tip linearly, indicating that the jaws were not suited for high precision catching of small prey but for delivering slashing wounds to weaken big prey.

As a consequence, according to this study, Carnotaurus must have mainly preyed upon large animals, possibly by ambush.

Robert Bakker found that Carnotaurus mainly fed upon very large prey, especially sauropods. As he noted, several adaptations of the skull—the short snout, the relatively small teeth and the strong back of the skull occiput —had independently evolved in Allosaurus.

These features suggest that the upper jaw was used like a serrated club to inflict wounds; big sauropods would have been weakened by repeated attacks.

Mazzetta and colleagues , presumed that Carnotaurus was a swift runner, arguing that the thigh bone was adapted to withstand high bending moments while running.

The ability of an animal's leg to withstand those forces limits its top speed. The running adaptations of Carnotaurus would have been better than those of a human, although not nearly as good as those of an ostrich.

In dinosaurs, the most important locomotor muscle was located in the tail. This muscle, called the caudofemoralis , attaches to the fourth trochanter , a prominent ridge on the thigh bone, and pulls the thigh bone backwards when contracted.

Scott Persons and Phil Currie note that in the tail vertebrae of Carnotaurus , the caudal ribs did not protrude horizontally "T-shaped" , but were angled against the vertical axis of the vertebrae, forming a "V".

Therefore, Carnotaurus could have been one of the fastest large theropods. These muscles, called the longissimus and spinalis muscle, were responsible for tail movement and stability.

To maintain tail stability in spite of reduction of these muscles, the caudal ribs bear forward projecting processes interlocking the vertebrae with each other and with the pelvis, stiffening the tail.

As a consequence, the ability to make tight turns would have been diminished, because the hip and tail had to be turned simultaneously, unlike in other theropods.

Ever since its starring role in the late, unlamented Steven Spielberg TV show Terra Nova , Carnotaurus has been rising quickly in the worldwide dinosaur rankings.

When he unearthed its single, well-preserved fossil from an Argentinean fossil bed, in , the famous paleontologist Jose F.

Bonaparte was struck by this new dinosaur's prominent horns. He eventually bestowed the name Carnotaurus, or "meat-eating bull," on his discovery—one of the rare instances in which a dinosaur has been named after a mammal another example is Hippodraco , the "horse dragon," a genus of ornithopod.

We say "somewhat surprisingly" because many theropods of the late Cretaceous period possessed feathers, and even T.

Rex hatchlings may have been tufted. This isn't to say that Carnotaurus lacked any feathers at all; to determine that conclusively would require additional fossil specimens.

It is also estimated that these dinosaurs were fairly fast. Some computer models suggest that the Carnotaurus could travel at a speed of about 35 miles per hour.

This would make it significantly faster than a running human and make it almost as fast as a cougar.
