The ancestor of the mosasaur came from the land and was a small lizard, the ancient coastal lizard. In 1989, the discovery of Dallas lizard fossils also allowed scientists to find information about their evolution. Scientists have reconstructed this fossil. These are creatures dating back 95 million years. Because they were threatened by the most ferocious dinosaurs on earth, they chose a relatively safe place: the ocean. After 3 million years, they gradually evolved into the Dallas lizard. Six million years later, they gradually evolved from a small meter-long lizard to a 15-meter-long giant mosasaur. This is what scientists speculate about the evolution of mosasaurs.
In the development process of Mosasaurus, warm sea water played an important role. The rich food sources contained in seawater have provided an excellent living environmentto Mosasaurus, and the battle for dominance of the ocean began. Mosasaurs wiped out all their competitors in the ocean in 5 million years. It can be said that they are the most successful predators among sea creatures and deserve to be the lords of the ocean in ancient times.
The strong jaws and sharp teeth are enough to cut prey in half.
About 70 million years ago, the Earth's continent was still ruled by the Tyrannosaurus rex. However, the area ruled by the Tyrannosaurus rex could only be land, as the ocean at that time was ruled by another terrifying creature. the Canglong. Some people who know something about Mosasaurus will realize how scary Mosasaurus is, but there are also people who don't know much about Mosasaurus. How terribly deadly was the Canglong that once dominated the ocean? THEMosasaurus that once dominated the ocean?According to scientific research, it is believed that the predecessor of the mosasaur was the cliff lizard, which means that the mosasaur evolved from the cliff lizard. The cliff lizard has been around for about 80 million years and is about less than a meter long. Its main habitat is the coast. However, with the gradual growth of dinosaur power, it caused serious damage to the habitats of other animals. Threatened, the cliff lizard had no choice but to survive in the ocean to protect itself. At first, cliff lizards only fed in shallow seas. Over time, they gradually adapted to life in the ocean and their bodies began to change rapidly in the water and their toes transformed into webbed feet. During the evolutionary process which lasted about 10 million years, the cliff lizard evolvedgradually transformed into a mosasaur.
Mosasaurs were the main predators of the oceans during the Mesozoic era. For example, among mosasaurs, Hoffmann's mosasaur is recognized as the longest animal, with a body length of up to 17.1 meters. Mosasaurus belongs to a group of carnivorous reptiles with a very huge head, strong jaws and sharp teeth, and resembles a crocodile with fins. Although mosasaurs were relatively large, unlike other large, bulky animals, mosasaurs were extremely agile. According to research on Mosasaurus, the Canglong's tail is half of its body length, and the swinging of the tail can provide a huge thrust to the Mosasaurus. Coupled with fins, the Mosasaurus' swimming speed can reach 50 km/h.
About 85 million years ago, the mosasaur's primary habitat was on the sea floor of the mer western interior, in the wilderness of Kansas, United States. At that time, the Earth's climate was relatively warm, there were no large-scale ice sheets, and about 80% of the Earth's surface was covered by oceans. It wasn't until the late 1830s that the bones of an unknown giant beast were first discovered in North America.
The sharp teeth of Mosasaurus are conical, curved and barb-shaped, and the torque generated by the jaws when biting is sufficient to split the prey in two. They drove out their adversaries in nearly 100,000 years and eventually became the dominant lords of the oceans in that time. Although Mosasaurus dominated for a while and was famous for about a million years, the history of Mosasaurus on earth is relatively short.
