Since the first studies on dinosaurs, representations and understandings of these prehistoric creatures have constantly evolved. What we know or think we know about them is often shaped by recent discoveries and new interpretations of available data. Here, we’ll explore six facts about dinosaurs that you probably thought were true but are actually incorrect.
1. T-Rex: Hollywood got it right and wrong
O Tyrannosaurus rex, one of the most famous dinosaurs, is often portrayed in films with its huge teeth ready to devour the protagonists. However, recent studies indicate that O t-rex probably had lips that covered its teethinstead of exposing them like crocodiles.
Furthermore, although some fossils show evidence of feathers, the largest and most recent t-rex did not have this feature. In this regard, points for the cinema.
2. Tiny Velociraptors
Contrary to the popular image of big, ferocious velociraptors, these dinosaurs were actually quite small. And when we say small, we mean really small, something the size of a turkey.
Contrary to what was shown in films, these animals did not hunt in packs and their claws — contrary to what the film Jurassic Park made us believe — they were not used as weapons. Instead, these dinosaurs likely had hunting behavior that more closely resembles that of recent predators, which shows that it was not the effective and deadly hunter we saw on screen.
3. Mosasaurus and its shark tail
Mosasaurs, giant marine reptiles, are often depicted with a narrow, lizard-like tail, which makes sense since it is an aquatic reptile. However, Recent fossils suggest that these animals had a large tail similar to that of sharkswhich could allow for faster swims for longer periods of time.
This discovery challenges the previous idea that mosasaurs had locomotion similar to that of terrestrial reptiles and leads us to rethink their adaptation to the aquatic environment. One thing is certain: they were much more dangerous than we imagined.
4. Real appearance of megalodon
For decades, megalodon has been portrayed as a gigantic great white shark, thanks to films like Megashark. However, more recent research suggests that this representation is mistaken.
Although no complete skeleton of Megalodon has been found, studies based on fossilized teeth and vertebrae indicate that it was most similar to the mako shark (Isurus oxyrinchus) than with the great white shark, being therefore longer and thinner than previously thought.
5. Woolly mammoths: not all are brown
Woolly mammoths, often depicted with reddish-brown fur, have recently been discovered in a variety of colors. Based on studies of DNA extracted from mammoth bones, it was discovered that These animals could have dark brown, light red or blonde fur..
6. Diplodocus and creep feeding
Diplodocus, known for their long necks, are often pictured munching on treetops like giraffes. However, recent studies suggest that these dinosaurs chewed most of their food close to the ground, feeding on low vegetation.
This challenges the previous idea that diplodocus had an exclusively arboreal diet and makes us reconsider their ecology and feeding behavior.
These examples highlight the importance of continued research and reassessment of evidence for accurately understanding dinosaurs and other extinct species. As new discoveries are made and new techniques are developed, our view of the past evolves and expands our knowledge of the prehistoric world.
