2 Ma Junlong
Ma Junlong
For Marjunosaurus, their bloodiest thing is cannibalism. Evidence of cannibalism comes from the tooth marks on their fossilized bones, which perfectly matched the size and clearance of the teeth of the dragons. MaJunlong is about 20 feet long and once lived on the plains of Madagascar 70 million years ago. According to the researchers, there were also small and thin plant-picking counterparts at that time. Research data shows that Ma Junlong not only feeds on the same kind of people who pick plants, but sometimes also feeds on their own family members. Cannibalism between dinosaurs is relatively common compared to other animals, but there is little evidence.
"Eocarcharia dinops" dragon
Under the eyebrows of the "Eocarcharia dinops" dragon is a huge brow bone. When confronted against the same kind, this thick brow bone can be used to violently hit the opponent and can also be used to attract the opposite sex. Their blade-like teeth can bite any living prey to death and dismember various parts of their bodies. In the Sahara Desert of Africa, fossils of the 110 million-year-old "Eocarcharia dinops" dragon have been found, including a nose like a pig's mouth. The dinosaur was about 7 feet tall and about 25 feet long. They often strike with another carnivorous animal, preying on long-necked herbivorous Nigerian dragons.
Norfleur Dragon
The multi-toothed Norphler dragon could use its protruding foreground teeth to stab at its prey like a spear, and then tear it apart with its blade-like hind teeth. This arrangement of teeth is rare in carnivorous dinosaurs. Scientists believe that this dinosaur, which is similar in size to the German Shepherd, lived in the southern part of the Gondwana supercontinent about 65 million to 70 million years ago, and mainly fed on fish, lizards and other animals. The first part of the English name Masiakasaurus knopfleri means "vicious lizard".
Utah casts a sickle dragon
Utahosaurus transformed from carnivorous to herbivorous. Scientists don't yet know why this bird-like-looking dinosaur gave up its carnivorous habits. However, their meat-tearing teeth have degenerated to cutting leaves, and their internal organs have swelled enough to allow plants to ferment in them. The Utahosaurus walked on two feet and stood about 4.5 feet (about 1.4 meters) tall. From head to tail, it is about 13 feet (about 4 meters) long. Their claws are long and sharp, about 4 inches (about 10 centimeters) long. The Utah dragon lived 125 million years ago in the early Cretaceous period and is active in what is now Utah, USA.
Duck-billed dinosaurs
For duck-billed dinosaurs, no plant was spared. Duckbill dinosaurs were large skeleton dinosaurs with a mouth like a duck's beak, and they could wipe out all the plants they passed by. Their skulls are large, with more than 300 teeth used to tear plant fibers. In its jawbone, there are also hundreds of teeth that can be replaced. This dinosaur lived about 75 million years ago in the late Cretaceous period, and its habitat was located in the west of a huge shallow sea that separated North America at that time. Adult duck-billed dinosaurs can reach 30 feet (about 9 meters) long and their heads are about 3 feet long.
