[31], Carnotaurus was the first theropod dinosaur discovered with a significant number of fossil skin impressions. [L][M][N] A 2016 study found that only Pycnonemosaurus, at 8.9 m (29.2 ft), was longer than Carnotaurus; it was estimated at 7.8 m (25.6 ft). Carnotaurus/Gallery | Dinosaur Wiki | Fandom.

A hummocky surface with grooves, pits, and small openings is found on the sides and front of the snout and indicates a scaly covering, possibly with flat scales as in today's crocodilians. The skeleton, dubbed Ebenezer, was donated to the museum. [53] Among the marine reptiles is the plesiosaur Sulcusuchus erraini of the family Polycotylidae.

Perhaps the weirdest and most noticeable feature of Carnotaurus is the pair of horns growing over the dinosaur’s eyes. This would have provided additional space for a caudofemoralis muscle larger than in any other theropod—the muscle mass was calculated at 111 to 137 kilograms (245 to 302 lb) per leg. [AM][7] Stephen Czerkas (1997) suggested that these structures may have protected the animal's sides while fighting members of the same species (conspecifics) and other theropods, arguing that similar structures can be found on the neck of the modern iguana where they provide limited protection in combat. and provide fossil replica and reliable scientific research data for museums.

Carnotaurus (meaning "meat (eating)-bull", referring to its distinct bull-like horns) was a large predatory dinosaur, with horns vaguely resembling a bull's. http://thegeekgroup.org/ - Carnotaurus has a lot more going for it than just being the meat-eater with the horns!

Majungasaurus was bipedal, with a long tail to balance out the head and torso, putting the center of gravity over the hips. [42] Carnotaurus may therefore have fed mainly on relatively small prey, but also was able to hunt large dinosaurs. [AU][47] Scientists calculate that Carnotaurus had a top speed of up to 48–56 km (30–35 mi) per hour. [1][AB] Reliable information on the shape of the teeth is therefore limited to replacement teeth and tooth roots that are still enclosed by the jaw, and can be studied using CT imaging. These processes were the highest points of the spine, towering above the unusually low spinous processes. The front end of the olfactory tracts and bulbs were curved downwards, a feature only shared by Indosaurus; in other abelisaurids, these structures were oriented horizontally. Carnotaurus was a lightly built, bipedal predator, measuring 7.5 to 9 m (24.6 to 29.5 ft) in length and weighing at least 1.35 metric tons (1.33 long tons; 1.49 short tons).
