Monsters that roamed the Earth during the Jurassic period remain fascinating and mysterious to this day. Although scientists have uncovered countless facts about these creatures, there are still many questions that remain unanswered to this day.
Often what we see on television programmes and films and read in books we accept as granted. However, what we see and hear from others may not be as reliable as we are made to believe. National Geographic has compiled five most popular myths about dinosaurs.
Dinosaurs dragged their tails on the ground
Up until a certain point in time it was believed that dinosaurs were very large reptiles. This is why it was considered that they dragged their tails on the ground when they moved about. A lot of research into dinosaurs has been done since 1970. Scientists have concluded that dinosaur were able to move their tails rather well. How else would some of them be able to reach running speed of 40 km/h with body weight of seven tons?
It was always sunny on Earth ruled by dinosaurs
The thought of dinosaurs often evokes an image of hot climate and lush jungles. It is worth keeping in mind that these animals populated all of Earth’s territories for 160 million years. This means they inhabited different climates and different locations. Large dinosaurs were slow, cold-blooded creatures. As it turns out, however, the Tyrannosaurus actually had cold and warm blood. The Spinosaurus was a carnivore that lived in water.
All dinosaurs were enormous because the world was different back then
Dinosaurs came in different shapes and sizes. This allowed them to survive for such a long time. It turns out that the Tyrannosaurus was not the largest monster. A skeleton of an ancient creature was found in Morocco: a 15-metre-long creature with large spines on its back. This monster was the Spinosaurus: an amphibious carnivore and the most brutal of ancient carnivores. According to some theories, the size of animals at the time depended on the Earth’s gravitational pull and air quality – there was more oxygen.
T-Rex roar was similar to that of a lion
Powerful roars are a sign of royalty, no? Everyone who has seen the Jurassic Park remembers the infamous T-Rex roar. Unfortunately, the sound that came from the T-Rex in that film was nothing more than the imagination of the film’s creators. Scientists continue researching reptiles and birds, hoping to understand their ‘speech’ and how dinosaurs communicated with one another. Maybe they sounded more like crocodiles or ostriches? We may never learn the truth, and it is highly unlikely that there is a 65-million-year-old audio tape lying somewhere in the ground.
Large dinosaurs had a second brain in their tail
This is an incredibly silly claim. The Stegosaurus had a large cavity just above their rear legs, which contained a large bundle of nerves. Palaeontologists of the 19th century believed these dinosaurs had a hind brain that coordinated leg and tail movements. However, it is common for vertebrates to have an extension in their spinal cord, which coordinates arm and leg movements without an auxiliary brain.
