DINOSAURS!

by: John Neal

Dilophosaurus

• This is one of the more diverse early Jurassic carnivores.

• The ceratosaurs, the group that dilophosaurus belonged to, went extinct at the end of this period.

Velociraptor

• This “raptor” dinosaur was made famous in the movie Jurassic Park. However, the size was twice the real size.

• An amazing find was found in the Gobi Desert with this small carnivore fighting a Protocerotops .

Miasaura

• This is one of the best known duck-billed dinosaurs.

• This is the only hadrosaur proven to have cared for their young.

Stegosaurus

• The scientist who first found Stegosaurus thought the plates laid down flat.

• This dinosaur was once thought to have had a second brain in it’s hip. We now know this is incorrect.

Acrocanthosaurus

• This is one of the rarest American dinos.

• This species had a fleshy sail on it’s back.

• This was a large land carnivore.

Einiosaurus

• This cerotopsin had a forward pointing horn used for an unknown purpose.

• The name of this dinosaur means “buffalo lizard”.

• This is only one of the many kinds of horned dinosaurs.

Dromeciomimus

• The family of dinosaurs that this belonged to are called the ornithomimids.

• This might have been the fastest of all dinos.

• Nobody knows what this ate.

Tyrannosaurus Rex

• This is one of the few dinosaurs known by its first and last scientific names.

• Despite the reputation, this wasn’t the largest land carnivore ever.

Seismosaurus

• This was one of the famous sauropods, which are known for their remarkably long necks.

• This was probably the longest dinosaur ever.

• About half of this dino is tail.

Utahraptor

• This is the largest known dromeosaur, or “raptor” dinosaur.

• The only reason this was found is because the finder eats faster than his daughter and wife.

Parasaurolophus

• This duck-bill had a backward pointing crest which may have supported a flap of skin.

• This is a rare hadrosaur.

Giganotosaurus

• This is the world’s largest carnivorous dinosaur.

• Giganotosaurus was 40 feet long.

Amargasaurus

• This sauropod had a double row of spikes jutting out of its neck and back.

• This was an herbivore.

Titanosaurus

• Unlike most sauropods, the titanosaurs lived in the Cretaceous period.

• This species lived in Asia and South America, so these were thriving. Close relatives are found on every continent except North America and Antarctica.

Argentinasaurus

• This is the largest land animal ever to have lived.

• You can see a skeleton of this creature at the Fernbank Museum.

• This was over 100 feet long and weighed 60 tons.

Dilong

• This strange dino may not look like it, but this was a close cousin of t-rex.

• This tyrannosaur had simple feathers, or “protofeathers”.

Ankylosaurus

• This powerful dinosaur had a lump of bone that was as big as both of your fists combined. This was used as a defensive weapon.

Spinosaurus

• The original skeleton was destroyed in World War Two.

• This was the T-Rex chasing villain of Jurassic Park Three.

• This dinosaur was up to 60 feet long!

Brachiosaurus

• This was once considered to be the tallest dinosaur. Now the tallest is sauroposiden.

• Brachiosaurus was 40 feet tall.

• This was an herbivore with a big belly.

Dromeosaurus

• This was the original “raptor” dinosaur.

• This was a little bit bigger than its cousin, velociraptor.

• Like its cousin, it was a carnivore.

Sauropelta

• This dinosaur had large spikes protruding out of its shoulders.

• This was an herbivore.

• Sauropelta was 17 feet long.

Centrosaurus

•There have been Bone Beds of Centrosaurus that have included over 200 individuals.•The centrosaurus was a 17 foot long herbivore that traveled in huge herds.

Lophostroepheus

• This was the largest carnivorous dinosaur of its time.

• This dino had many smaller cousins, such as coelophiysis.

• This dinosaur had an elongated neck to reach out and grab prey.

Lesothosaurus

• This is a very poorly understood dinosaur. All we know is that it is a bipedal (two-legged), small plant-eating dino.

• Though this was mostly an herbivore, this may have scavenged meat every now and then.
