Facts about Dinosaurs



The word dinosaur comes from the Greek language and means ‘terrible lizard’. The word was coined by English paleontologist Richard Owen in 1842 and was meant to refer to the dinosaur's impressive size rather than their scary appearance.

Dinosaurs ruled the Earth for over 160 million years, from the Triassic period around 230 million years ago through the Jurassic period and until the end of the Cretaceous period around 65 million years ago.

The time period from 250 million years ago until around 65 million years ago is known as the Mesozoic Era. It is often referred to as the Age of the Dinosaurs because most dinosaurs developed and became extinct during this time.

Scientists believe that the event leading to the extinction may have been a massive asteroid impact or huge volcanic activity. Events such as these could have blocked out sunlight and significantly changed the Earth’s ecology.

Dinosaur fossils have been found on every continent of Earth, including Antarctica.

Fossils help us understand what the dinosaurs were like. Information can be gathered from sources such as fossilized bones, footprints, stomach stones, feces, internal organs, soft tissues, eggs and feathers.

Scientists have no idea what color or colors the dinosaurs were.

Over 1000 different species of dinosaurs have been named and the list continues to grow as new fossils are discovered.

Some of the largest fossilized dinosaur eggs ever discovered were found in China in the mid 1990’s. The eggs are over 60cm (2ft) long and 20cm (8in) wide.

Thomas Jefferson found the first dinosaur fossil in the Americas and expostulated that giant creatures once roamed the Earth.

Dinosaur fossils have been known for a long time in human history but it wasn’t until the early 19th century that they were formally recognized as the dinosaurs we know about today.

In 1824, the first dinosaur was given a name. It was called the Megalosaurus.

In 1858, one of the first almost complete dinosaur skeletons was discovered in New Jersey, USA. What made this discovery special was that it was a bipedal dinosaur, meaning one that moved on two legs. Most scientists had previously thought that all dinosaurs moved on four feet. The discovery dramatically changed views and led to a huge increase in dinosaur interest among those living in the USA.

In 1868 the bones of a Hadrosaurus were used to create the first ever mounted dinosaur skeleton.

A person who studies dinosaurs is known as a paleontologist.

In 1888, Harry Seeley proposed a way of classifying dinosaurs into two groups by looking at their hip structure, these groups are called Saurischia (lizard hipped) and Ornithischia (bird hipped). The two groups can be further broken down into sub-groups such as families, sub-families and so on.

Rather than being carnivores (meat eaters), the largest dinosaurs such as the Brachiosaurus and Apatosaurus were actually herbivores (plant eaters).

To help fight meat eaters such as the Allosaurus or Spinosaurus, many plant eaters had natural weapons at their disposal. Examples of this include the spikes on the tail of the Stegosaurus and the three horns attached to the front of the Triceratops’s head shield.

Pterodactyls are not dinosaurs. They were flying reptiles that lived during the age of dinosaurs but by definition they do not fall into the same category. The same goes for water based reptiles such as Plesiosaurs.

Birds descended from a type of dinosaurs known as theropods.

Despite being long extinct, dinosaurs are frequently featured in the media. One of the more memorable examples of this is Michael Crichton’s 1990 book Jurassic Park. Adapted to movie in 1993, the story features cloned dinosaurs brought to life with the help of DNA found in mosquitoes trapped in amber.

Here are some of the most famous types of dinosaurs.

Tyrannosaurus rex

The word Tyrannosaurus comes from the Greek words meaning ‘tyrant lizard’, while the word ‘rex’ means ‘king’ in Latin. Tyrannosaurus rex is often abbreviated to T-Rex and lived in an area of the Earth that now makes up western North America.

Tyrannosaurus rex lived in the late Cretaceous Period, around 66 million years ago.

Tyrannosaurus rex walked on two legs, balancing its huge head with a long and heavy tail that sometimes contained over 40 vertebrae. It measured up to 13m (42ft) in length, 4m (13ft) at the hip and could weigh up to 7 tons. The skull of a Tyrannosaurus rex alone measured up to 1.5m (5ft) long. And, Tyrannosaurus rex had small arms that were extremely powerful and featured two clawed fingers. Finally, because of the lack of concrete evidence, it is difficult for scientists to work out how fast T-Rex could run, with estimates ranging from as low as 17kph (11mph) to as high as 70kph (43mph). Average estimates suggest a maxium speed of around 40kph (25mph).

The largest tooth of any carnivorous dinosaur found to this date is that of a T-Rex. It is estimated to have been around 30cm (12in) long when including the root.

When Tyrannosaurus rex was around the age of 14, its body size would increase rapidly, putting on around 600kg (1300lb) a year over the next 4 years.

There is also strong debate about whether Tyrannosaurus rex was a predator or scavenger. It had small arms which would have made it hard to grip prey, suggesting it may have been a scavenger. On the other hand, evidence in favor of it being a predator includes its forward pointing eyes which give better depth perception and make it easier to hunt.

Triceratops

The name ‘Triceratops’ comes from the Greek language, with ‘tri’ meaning three and ‘keratops’ meaning horned face.

Triceratops lived in the late Cretaceous Period (around 65 million years ago).

The Triceratops is one of the most easily recognizable dinosaurs due to its large body, unique frill and three horns. It needed its three horns to try and protect itself from the Tyrannosaurus Rex which lived during the same time period.

It is believed that fully grown Triceratops were about 8m (26ft) in length, 3m (10ft) in height and weighed anywhere between 6 to 12 tons.The skull of a Triceratops alone could grow over 2m (7ft) in length.

The Triceratops was a plant eating (herbivore) dinosaur. And, it had anywhere between 400 and 800 teeth, although only a small percentage of these were in use at any one time as they were constantly replaced throughout its lifetime.

Allosaurus

The name Allosaurus means ‘different lizard’.

Allosaurus lived around 150 million years ago in the late Jurassic Period.

Allosaurus was first described by Othniel Marsh in 1877 and become one of the first well known dinosaurs. Marsh also named and gave the first description of theApatosaurus (Brontosaurus) in that same year.

Most Allosaurus fossils have been found in the Morrison Formation, a distinctive band of sedimentary rock found in the western United States.

Allosaurus had a large skull and walked on two legs. Its body and head were balanced by a long and heavy tail. Like the Tyrannosaurs rex, the Allosaurus had short arms. It had three fingers that were each tipped with sharp, curved claws. And, research suggests that the average length of an Allosaurus was around 8.5 metres (28 feet) and that it weighed around 2.3 tons.

Iguanodon

The name Iguanodon means ‘Iguana tooth’.

Iguanodon lived in the early Cretaceous Period, around 125 million years ago.

The Iguanodon was first discovered in 1822 by English geologist Gideon Mantell.

The Iguanodon was a plant eater (herbivore).

It could easily shift between moving on two limbs or four.

The Iguanodon weighed around 3.5 tons and reached around 10 metres (33 feet) in length.

Iguanodon had a thin skull and long tail.

The largest collection of Iguanodon fossils were found in a Belgian coal mine in 1878. More than 35 skeletons were excavated, greatly helping scientists develop a better understanding of the dinosaur.

Scientists estimate the Iguanodon’s maximum speed would have been around 24kph (15mph).

Sauropods

The name Sauropod comes from the Greek language and means ‘lizard foot’.

Sauropods are a type of dinosaur that typically grew to enormous sizes.The biggest dinosaur ever is believed to be a Sauropod called Amphicoelias. This gigantic dinosaur could have reached as long 60 metres (200 feet) in length and weighed up to 120 tons.

Studies suggest that Sauropods reached heights of up to 18m (60ft), lengths of up to 34m (110ft) and weights of up to 100 metric tons. Only the Blue Whale manages to compete with the Sauropods when it comes to size, and it lives in the water rather than on land like the Sauropods did.

Sauropods first appeared on the scene in the Triassic Period (around 200 million years ago) and became quite common late in the Jurassic Period (around 150 million years ago).

Sauropod fossils have been found on every continent of Earth, even in Antarctica.

The Sauropods became extinct around 65 million years ago.
