Dinosaurs have been depicted in many different forms from past to present. Even when dinosaur fossils were just found very similar to iguana was thought.

Thanks to the fact that we now have access to so many fossils what they look like we know very little. So how were they depicted if there weren’t enough fossils?

Who are these dinosaurs?

Dinosaurs originated 233-243 million years ago. living members only Arcosaurus is a group of reptiles that are birds. Where they live, how many species they have, how they disappeared and their place in the ecosystem have always been the subject of research for science.

The ground will make the mass vibrate It has been documented that there are 1,000 species of dinosaurs of this size. While there weren’t as many fossils as we could find of them, they were thought to be somewhat different from their current depictions.

Based on the first jaw fossil found, it was thought to be a large reptile.

One about 2 meters long found in 1824. jaw fossilIt is taken to Oxford Geological Engineer William Buckland for examination. Buckland claims it belongs to a large reptile, based only on the jaw fossil.

Based on this fossil, it was named Megalosaurus. carnivorous dinosaur, is shown in the figure above. According to the fossils we have reached today, the actual appearance of the megalosaurus is as in the picture below:

It was estimated to resemble a giant iguana.

Dedicated to fossils, British geologist Dr. Gideon Algernon Mantell described this creature using the found dental fossils. a small lizard It shows the iguana as a giant shape. Therefore, the owner of the teeth is called “Iguanodon”. “iguana equipment” gives his name.

When the bones found later were examined, the dinosaurs were horned animals It is thought to be a finger, but in the picture that emerged with the discovery of other fossils, the bone they thought was horn was actually a finger.

Depicted dinosaur species with upward spines: Hylaeosaurus

When the first fossil remains of Hylaeosaurus were found in the 1830s, to thorny bones thought to have. With the remains later completed, it appears that his spiky bones were actually sideways.

These bones, Hylaeosaurus because it is herbivorous It was developed in such a way that other carnivorous dinosaur species could not come close.

“Deinos+Sauros”, which means “terrible lizard”.

1842, the British comparative anatomist Lord Richard Owen; It comparatively examines Megalosaurus, Iguanadon and Hylaeosaurus. In his examination he sees serious similarities, especially in the foot and hip bones.

So in Greek deinos (terrible) + sauros (lizard) combining the names we know as “dinosaur”.
