Neptunus: The ancient large sea creature was 17 meters long/the tail was half the length.

Tylosaurus is a mosasaur, an ancient reptile of the order Squamata. It lived at the same time as most dinosaurs and originated at the end of the Cretaceous period. It is related to modern snakes or lizards. similar to that of Plesiosaurus, Liopleurodon, etc. It was the largest mosasaur at that time, with a body length of up to 14-17 meters.

Neptunus is one of the largest carnivorous reptiles. Its body length can reach 14 to 17 meters and its weight can reach around 10 tons, of which its tail makes up the majority. body length. Half, which also grants him enormous swimming power, giving him a very powerful hunting ability. As a result, Tylosaurus became one of the most powerful predators of its time.

The general appearance of Neptunus is very similar to that of a modern monitor lizard or crocodile,somewhat similar to Liopleurodon, but the difference is that its limbs are all fin-shaped, mainly to be able to swim better and faster. The neck of Neptunus is very short and thick, the body is slender, especially the tail is extremely thin, the mouth is very large and wide, the corners of the mouth are split on the sides of the cheeks, the teeth are small but dense, and the bite force is extremely strong.

Neptune was the main predator in the ocean during the Cretaceous period, so it could not only eat a few small mosasaurs and plesiosaurs, but also prey on many sharks, even the fossil of a flightless evening. The bird was found in his stomach. It can be said that it had a wide range of feeding habits, so it lived mainly in shallow waters and near the banks. When hunting, in addition to using extreme swimming speedAlthough fast and gnawing, Tritonosaurus also used its long jaw bones to strike, thereby stunning its prey.

The first Tylosaurus fossils were discovered in 1869, when Edward Drinker Cope discovered fossil fragments in western Kansas, United States, including Three vertebrae and a skull fragment was eventually preserved in the Harvard Museum. At that time, it was once considered a platydon among mosasaurs. However, it was not until the complete fossil was discovered again in 1872 that it was finally identified as Tylosaurus.
