Dinosaurs, Cretaceous dinosaurs, Cretaceous era, and Cretaceous period

Adasaurus

The Adasaurus is closely related to the Dromaeosaurus. It was equiped with the same razor sharp claw on each of its hind feet.

Achelousaurus

The Achelousaurus is a quadrupedel herbivore which means that it walked on all four legs as opposed to two legs.

Afrovenator

The Afrovenator name means African Hunter.

Agujaceratops

When the Agujaceratops was first discovered paleotologists thought that it was a Chasmosaurus until years later, when they realizes its a totally new species

Alamosaurus

The Alamosaurus was first discovered in 1922 Charles Gilmore. He found a pelvic bone and a shoulder bone.

Altirhinus

Altirhinus got its name in 1998 from the latin word altus(high) and the Greek word rhinos (nose).

Animantarx

Fossil finding of the Animantarx suggest that the dinosaur was this was know to be in a floodplain environment.

Ankylosaurus

The estimated length of the Ankylosaurus is 9 meters (30 ft).

Buitreraptor

Buitreraptor lived about 90 million years ago.

Carcharodontosaurus

Cercharodontosaurus lived 90 to 100 million years ago.

Carnotaurus

The closest relatives of Carnotaurus are the Aucasaurus, Majungasaurus, and Rajasaurus.

Centrosaurus

The Centrosaurus belongs to the sub-family Centrosaurinae which was named after the dinosaur.

Chirostenotes

The Chirostenotesis thought to be an omnivore meaning that it eats meat as well as plants.

Corythosaurus

Corythosaurus' had a beak and not a mouth. there was no teeth in the front, but rows of them in the back of the jaw.

Deinonychus

The Deinonychus was about 11 feet in length with a skull about the size of 16.5inches.

Dromaeosaurus

Dromaeosaurus is from the Dromaeosaurinae group. This dinosaurs such as theUtahraptor, Achillobator, and Adasaurus were in the same group.

Falcarius

The Falacarius got its name from the word sickle. Falcarius in Latin means sickle cutter, which scientists have used to describe its awkward clawed hands.

Gallimimus

Gallimimus are thought to be very fast because they were very Ostrich-like, but there is not much evidence that this is true.

Giganotosaurus

Giganotosaurus was discovered in 1993 by Ruben Carolini.

Hesperonychus

The Hesperonychus is known from a partial skeleton found by Elizabeth Nicholls.

Iguanodon

Many Iguanodon fossils were found in many far apart locations such as Europe, Asia, Canada, USA, and Africa.

Monoclonius

The Monoclonius is of the Ceratopsia group.

Nanotyrannus

Most paleontologists now are convinced that Nanotyrannus was actually a juvenile Tyrannosaurus and not a separate genus of dinosaur.

Nigersaurus

There has been mentionings that the Nigersaurusmay have been responsible for dinosaur extinction by exhausting to plant life and causing starvation.

Olorotitan

Olorotitan fossils have been found with nearby fossils of turtles, crocodilians, theropod dinosaurs, and nodosaurid dinosaurs.

Pachycephalosaurus

The Pachycephalosaurus Large helmet on its head was originally thought to be for competition with bumping heads. This thought has been frowned upon because they would've easily been injured this way.

Parasaurolophus

The long tube-like crest on the Parasaurolophus is not known what its purpose is for sure. Some say that it was for thermoregulatory functions to control its temperature.

Polacanthus

Polacanthus was first discovered in 1865 by William Fox. The same year it was named by a man by the name of Richard Owen.

Rapator

The Rapator was found in the Griman Creek Formation at New South Wales, Australia. The first time it was described was in 1932.

Suchomimus

Suchomimus had a very high sail along its back that was probably used to let out body head and have advanced controlling of its temperature.

Stygimoloch

The Stygimoloch name means in Greek "horned devil from the river of death" and it walked upright on its two feet.

Tarchia

The Tarchia is is currently the geologically youngest known of all the Asian ankylosaurid dinosaurs.

Torosaurus

Torosaurus are from the dinosaur group "ceratopians" which means bird-hipped. This group of dinosaurs had a lot in common with bird such as a beak instead of a mouth.

The name Triceratops actually means "Three horned face." It was named by Othniel Charles Marsh on the third try. He first named it Bison alticornis, then Ceratops, to finally later called it Triceratops.

Troodon

The name Troodon is Greek for Wounding tooth. This refers to the dinosaurs teeth which had apically oriented serrations. This was very rare with other theropods

Tsaagan Mangas

The Research of the Tsaagan Mangas is based on only a single skull fossil because there has never been any findings since.

Tsintaosaurus

scientists argue of the purpose of the Tsintaosaurus' horn-like crest.

Tyrannosauropus

Fossils were found with a Protoceratops & Raptor that seem to have been fighting when they were quickly killed. The claw of the raptor was in the others' stomach.

Tyrannosaurus

The Tyrannosaurus was thought to be the biggest Carnivore ever to exist, but its not. The Giganotosaurus is actually the biggest.

Utahraptor

To help it balance on one foot while kicking, the Utahraptors' tail stiffened.

Velociraptor

Fossils were found with a Protoceratops & Raptor that seem to have been fighting when they were quickly killed. The claw of the raptor was in the others' stomach.

Cretaceous Period Dinosaurs

Click on any of the pics or names above to learn specifically about that particular dinosaur of this period. The Cretaceous life is the time period of 135 to 65 million years ago. This was the last period of the dinosaur evolution chain. For reasons unknown today, all dinosaurs became extinct at the end of this Era. There is a lot more dinosaur species in the Cretaceous period than the other two dinosaur periods. The discoveries of fossils are typically in much better quality than the other two prehistoric time lines and due to less deterioration. The most famous dinosaurs known of the Cretaceous period is the massive Tyrannosaurus and the fearsome Velociraptor.
