Dinosaurs were once a reptile 230 million years ago but suddenly disappeared all at the end of the Cretaceous Period 65 million years ago, becoming a mystery in the evolutionary history of life on Earth. There are also many types of dinosaurs, among which there are very peculiar dinosaurs, do you know which ones?
1. Mamenchisaurus: The long neck is used to win the favor of the opposite sex
Known as the giraffe in the dinosaurs, Mamenchisaurus was a herbivorous dinosaur with a neck and tail twice as long as its body. While many people believe that long-necked animals, including giraffes, evolved to obtain food from taller trees, paleontologists say Mamenchisaurus’s long necks originated from mate selection.
2. Carnotaurus: With bull horns and unusually short forelimbs
Carnotaurus was a ferocious-looking dinosaur, but it was also a species that puzzled paleontologists. It looks fierce, 25 feet long, with protrusions like bull horns, jaws like a box, and sharp teeth exposed. However, despite its large shoulder blades, its forelimbs are very small. Phil Manning, a British paleontologist, said: “Carnotaurus is one of the most peculiar-looking dinosaur species.”
3. Parasaurolophus: Its skull looks like a banana
Paractenosaurus is a dinosaur that appeared in the sci-fi movie “Jurassic Park”. It is one of the most peculiar species in the dinosaur kingdom. It has a banana-shaped crown structure. The banana-shaped crown has been hotly debated among scientists, with some arguing that it could have improved Paractenosaurus’ ability to smell, or helped regulate body temperature. Others believe that this crown can transmit sound signals.
4. Triceratops: Its horns are tools for courtship and territorial establishment
Triceratops had three horns on their heads, and this peculiar structure has become a topic of controversy among scientists. Scientists generally believe that triceratops’ horns could hold their necks, or be deadly weapons in combat. But at present, many people think that these three horns are just tools for showing off and establishing dominion during the courtship period…
5. Spinosaurus: An example of showing off wild evolution
About 60 feet long, Spinosaurus was one of the largest carnivorous dinosaur species, even bigger than the fearsome Tyrannosaurus rex. But what paleontologists have been puzzled by is the function of the 5-foot-long fin-like protrusions on the back of Spinosaurus. Paul C. Sereno, a paleontologist at the University of Chicago, said: “The sail-like fin can increase its weight and make it easier to smell by its prey, but the structure is not an advantage for it. So I think this body structure is just a body show, It’s trying to prove: ‘Hey! I can have 5-foot sail fins, I’m fit, I’m bigger than you!’
6. Epidexipteryx-It is a close relative of birds, but cannot fly
Living in the Jurassic period, with a body length of more than 40 centimeters, it belongs to the bird-wing class, representing one of the closest dinosaurs to birds. Epidexipteryx is petite, about the size of a pigeon. But because it has no flying feathers, “Epidexipteryx” does not have the ability to fly.
7. Suzhousaurus: Hairless giant turkey
The currently known fossils were found in Gansu Province, China. Fossils include partial skull and upper limb fossils, confirming that they belong to the Therizinosauroidea. According to scientists, Suzhousaurus lived in the early Cretaceous period. Suzhousaurus may be the most bizarre-looking dinosaur ever discovered, looking like a giant hairless turkey.
8. Gryposaurus: Fighting with nose
Gryposaurus is a dinosaur of the hadrosaurs. Lived about 83 million to 75 million years ago. Gryposaurus has a hooked nose, a “cockscomb” on its head, and its mouth is a duck’s mouth. Although the claws of Gryposaurus are longer than that of ordinary dinosaurs, in fact, it mostly uses its nose when fighting.
9. Microraptor: One of the smallest known dinosaurs
Microraptor is a small Dromaeosauridae discovered in Liaoning Province, China, Existed in the early Cretaceous Barremian, about 130 million to 125.5 million years ago. Nearly 10 complete fossils have been found so far. Microraptor is one of the smallest known dinosaurs, measuring 55 to 77 centimeters in length. In addition, Microraptor was one of the first dinosaurs to be found to have feathers and wings.
10. Tanystropheus: The neck is half the length of the body
Tanystropheus is a reptile that lived in the Middle Triassic, with a body length of about 6 meters. The main feature is the extremely long neck, which is 3 meters long, longer than the body and tail combined.
Since dinosaurs are ancient prehistoric creatures, most dinosaurs are “peculiar” to humans…peculiar appearance, habits, characteristics…We have also been amazed by new discoveries about dinosaurs.
