Lexovisaurus Dinosaur

Lexovisaurus Dinosaur - 2

Origin

Lexovisaurus belongs to the category of spinous dinosaurs and is a primitive form of prehistoric animal that lived in the Mesozoic era in the Middle Triasic about 164 million years ago.

The skeleton of this dinosaur was reconstructed on the basis of just a few fossils found in England and northern France. Based on their study, it was concluded that this animal would very much resemble the dinosaur Kentrosaurus who lived in the Upper Jurassic.

However, considering the way the two rows of bone plates were arranged from the front of the head to the middle of the back, as well as the appearance of the two pairs of thorns that were tilted to the top of the rib, some researchers resembled this creature with the Jurassic Stegosaurus higher.

In 1957, paleontologist R. Hoffstetter described this species in detail and called it Lexovisaurus durobrivensis. The length of an adult Lexovisaurus was estimated at 5 m and the weight at about one tonne.

The back plates were larger than those in the neck, they suspect they were not caught by the skeleton of the animal, but were implanted in thick and scaly skin, forming a shield that protected much of the body. The plates were covered with rich thick vascular skin – through which the dinosaur was able to control heat exchanges with the environment.

The spines on the tail were very long and sharp, like very dangerous huge horns, they could cause serious wounds any time on the predatory dinosaur’s body. In the shoulder area, on the sides, the animal had a pair of long thorns protecting the vulnerable flanks of the body.

The posterior members were very long and strong, they had broad thighs with large muscle inserts, and slightly smaller anterior limbs were well developed to help support the massive body of the animal. Walking was quadrupled, the dinosaur’s usual position was bent by the shorter limbs. The elbows were strong, ending with thick fingers and hooves.

The head was small, the elongated toe has jaws provided with small and sharp teeth, which often do not cope with the crushing process. That’s why the dinosaur used to swallow stomach stones with sharp edges – called gastrolites – to help crush the stomachs in the stomach and ease digestion.

When the stones were being thrown, they were thrown out and replaced with new ones, gathered from the banks of the rivers.

During the breeding period, the females dug holes into the ground and deposited a certain number of eggs, eliminated by the cloaca – an organ in the posterior part of the body. The eggs were covered with plants to be kept at the constant temperature required for tampering.

Lexovisaurus’s Food

These herbivorous animals lived in hundreds or even thousands of flocks in forested areas near watercourses and fed with all sorts of plants at the ground level.
