A large tomb has been discovered in Britain. The discovery suggests that creatures that lived during the Jurassic period were as bizarre as they came from another planet, according to researchers. Scientific warning Science Portal.

Experts found the remains of tens of thousands of animals at the site. All creatures that once lived are spinal cord colored (Echinoderma) This group still has a large number of members, including the spiny-skinned starfish for example. Fossils have acquired all stages of the animal life cycle for offspring – Stands CommunicationPublished by the Museum of Natural History in London.

The inhabitants of the Jurassic Sea were eventually wiped out by a major natural disaster, which is not yet fully known. The catastrophic landslide 167 million years ago may have been a major earthquake that buried the animals.

What we see is really a Jurassic Pompey “ said To the BBC Neville Hollingworth is an amateur fossil researcher.

According to Tim Evin, an archaeologist at the Museum of Natural History in London, the animals took a defensive stance when they died, evidence that their hands were retracted. They were properly immersed in the sediment buried alive. “ He added.

Depending on the age of the site, the animals found here may have lived between the Jurassic period (200-145 million years ago). This is the biggest in this era sauropoda And bloodlust Theropoda The planet trembled at the footsteps of the dinosaurs, and great changes took place in the ocean; Extinction occurred at the end of the Triassic extinct aquatic life, and vacant ecological spaces began to be filled with limp limbs with sharp skin.

Animals with radial symmetry caught their prey with sharp hands.

Some species kept changing their position, while others waited for prey to approach and then only fall down.

The sea, which covers the area, is relatively shallow, about 20-40 meters deep. The seabed under study is now in central England, but 200 million years ago it was even farther closer to North Africa, and seawater was warmer than it is today. In addition to the bodies of native animals, the sedimentary layer also preserved fossil wood remains and pollen. The latter can provide additional information on ancient climate change.

Scientists can learn more about the evolution of the thorny tribes by studying the fossils now found.
