Dinosaurs

Dinosaurs were the dominant vertebrate animals of terrestrial ecosystems for over 160 million years, from the late Triassic period until the end of the Cretaceous period

Some Kinds of Dinosaurs

There are different kinds of dinosaurs. Her are some:

Albertosaurus Brachiosaurus Compsognathus Diplodocus Giganotosaurus Iguanodon Tyrannosaurus Spinosaurus

Albertosaurus Albertosaurus is a genus of

tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period. It may have been at the top of the food chain in its local ecosystem. even relatively large for a theropod, Albertosaurus was much smaller than Tyrannosaurus.

Brachiosaurus

Brachiosaurus was a genus of sauropod dinosaur that lived during the Late Jurassic Period and possibly the Early Cretaceous Period. It was one of the largest animals known to have walked the earth. It has become one of the most famous of all dinosaurs and is recognized worldwide.

Compsognathus

Compsognathus was a small, bipedal, carnivorous theropod dinosaur The animal was the size of a turkey and lived around 150 million years ago. Although not recognized as such at the time of its discovery, Compsognathus is the first dinosaur known from a reasonably complete skeleton.

Diplodocus

Diplodocus is a genus of diplodocid sauropod dinosaur whose fossils were first discovered in 1877 by S. W. Williston. It lived in what is now western North America at the end of the Jurassic Period.

Giganotosaurus

Giganotosaurus is a genus of carcharodontosaurid dinosaur that lived 93 to 89 million years ago. It is one of the largest known terrestrial carnivores, slightly larger than Tyrannosaurus, but smaller than Spinosaurus.

Iguanodon

Iguanodon is a genus of ornithopod dinosaur that lived roughly halfway between the first of the swift bipedal hypsilophodontids and the ornithopods' culmination in the duck-billed dinosaurs

Tyrannosaurus

Tyrannosaurus is a genus of theropod dinosaur. The famous species Tyrannosaurus rex commonly abbreviated to T. rex. Fossils of T. rex are found in a variety of rock formations dating to the last three million years of the Cretaceous Period.

Spinosaurus

Spinosaurus is a genus of theropod dinosaur. They lived in what is now North Africa, from the Albian to early Cenomanian stages of the Cretaceous period
