A huge cemetery was found in Britain. According to researchers, the creatures that lived in the Jurassic period are as strange as if they came from another planet. Science alert Scientific portal.
Experts have found the remains of tens of thousands of primates at the site. Creatures that once lived are all spiny-skinned.echinoderms). The group still has a large number of members, including the spiny starfish, for example. Fossils have inherited all stages of an animal’s life cycle for future generations – standing on CommunicationPublished by the Natural History Museum in London.
The inhabitants of the bottom of the Jurassic Sea were eventually destroyed by a huge natural disaster, which is not yet fully known. The disaster that occurred 167 million years ago may have been a massive earthquake that caused a landslide and buried primates.
What we see is actually Jurassic Pompeii” . said to the BBC Neville Hollingworth is an amateur fossil researcher who was touring with his wife around the Cotswolds in the UK when he found the unparalleled finds.
According to Tim Ewen, a paleontologist at the Natural History Museum in London, the animals took a defensive stance when they died, as evidenced by the fact that their arms were retracted. They were properly submerged in the sediment that buried them alive.” he added.

Depending on the age of the site, the animals found here may have lived in the middle of the Jurassic period (200-145 million years ago). It’s huge nowadays sauropod bloodthirsty theropod The planet trembled in the footsteps of the dinosaurs and great changes took place in the seas. The extinction occurred at the end of the decimated watery Triassic, and the vacated ecological niches began to be filled with spiky-skinned limbs.
Animals with radial symmetry grabbed their prey with their barbed arms.
Some species continued to change position, while others waited until the prey became close to it and only then was it struck.
According to the researchers, the sea covering the area was relatively shallow, with a depth of 20-40 meters. The seafloor remains under study are now located in central England, but 200 million years ago they were further, near North Africa, and the sea water was much warmer than it is today. In addition to the bodies of local animals, the sediment layer also preserved the remains of petrified wood and pollen. The latter could provide additional information on paleoclimate change.
Scientists can learn more about the evolution of the thorny tribe by studying the fossils that are now found.
