Deadly, gigantic, and hungry, the Carcharodontosaurus was one of the most fearsome predators of the mid-Cretaceous. This massive theropod is sometimes nicknamed “The Moroccan T. Rex,” though it was actually related to the even larger Giganotosaurus. Carcharodontosaurus is estimated to have grown as large as 44 feet long with a weight of 16 tons, with a terrifying set of serrated teeth to match, which it used to dominate the Kem Kem river delta.

This specimen is a complete crown of a real, fossilized Carcharodontosaurus tooth from the Kem Kem fossil beds of Morocco.
The specimen is enclosed in a handsome, glass-topped riker box case. A small information card is also included.
Carcharodontosaurus Tooth Sizes:

As you might expect, Carcharodontosaurus teeth vary in size, width, and color. For convenience we've grouped teeth into similar sizes by length and "visual weight" in order to assign then to categories:
- Small - 1" to 1.5" (approximately 2.5cm to 3.8cm)
- Large - 1.5" to 2" (approximately 3.8cm to 5cm)
Both sizes ship in a glass-topped riker box case measuring 4 1/2" x 3 1/2". All teeth include a small information card that also serves as the certificate of authenticity.
Please note: All teeth will show some sign of repair. In addition, to protect the specimen during transit every Carcharodontosaurus tooth is individually wrapped.
On receipt, simply open the top of the case and unwrap the tooth and then arrange the tooth inside the case as pictured here on the site. We also recommend placing the bubble wrap under the soft, white lining of the case. This extra padding will keep the tooth snug in the case after the lid is secured.

The new specimen is as long or longer than any skull of Tyrannosaurus rex, which has always been referred to as the largest known terrestrial carnivore." ~ Philip J. Currie

Fossils from Carcharodontosaurus were first discovered in 1924 when two teeth were found in Algeria. Other fossils were uncovered in the region but ended up destroyed due to fighting from World War II. In 1995, parts of a new skull were uncovered in Morocco, which put estimates to the creature’s head at almost 5 feet long. Housed in this massive skull were powerful jaws of serrated teeth measuring up to 8 inches in length. These teeth helped Carcharodontosaurus tear and shred its meals while it was on the hunt, and the size of its maw allowed it to easily grab and trap prey.

The huge teeth are also what give Carcharodontosaurus its mouthful of a name. The species was named after the discovery of the teeth, which resembled that of the great white shark, a member of the genus Carcharodon. Carcharodon sharks, in turn, take their names from the Greek for “jagged teeth,” karcharos and odōn.
Ancestors of Carcharodontosaurus are believed to have radiated out from Africa in the early Cretaceous period before becoming isolated around 90 million years ago. The cousins to Carcharodontosaurus encompass a wide variety of dinosaurs, from the comparably smaller Allosaurus to the semi-aquatic Spinosaurus, and the massive Giganotosaurus, all of which were dangerous predators in their own right.
Giganotosaurus in particular shared quite a close relation with Carcharodontosaurus, with a similar shape, size, and diet. The two were primarily separated by the ocean between Africa and South America.

Some Carcharodontosaurus remains have been found within hunting proximity of other predator families like abelisaurids and spinosaurids. How did these apex theropods manage to coexist with each other? While it’s very likely the carnivores fought with each other over territory, they also had very different teeth structures. Because of this, it's thought that the dinosaurs fulfilled unique ecological niches, meaning there would be less rivalry for food.

This specimen comes from the Kem Kem Beds in Morocco. During the Cretaceous Period, this region was part of a vast river system. In recent years members of the Spinosaurus family have been found in many parts of the world including Europe, South America, and even Australia.
