There have been many such creatures in the ancient history of the earth which became extinct and we never came to know about them. Similar was found in the Limestone Quarry of ‘Treasure’ in the Coswalds region of Britain. Archaeologists have found a deposit of fossils here. Buried here were sea creatures of the Jurassic period, which today seem like aliens. Millions of such invertebrates were found here, which do not have a backbone.
16.7 crores ago event
These include the ancestors of organisms such as today’s starfish, sea cucumber, sea urchin and sea lilies. According to the researchers, this whole life ended together due to some mysterious disaster. It is believed that these creatures were buried in a landslide due to an earthquake-like event about 167 million years ago and today their fossils have been found preserved at the same stage of their life.
trying to save myself
The discovery was made by fossil finders Neville Hollingworth and his wife Sally during a hike. Tim Evin, an archaeologist and senior curator at the Natural History Museum in London, told the BBC that the creatures may have been trying to defend themselves but were buried alive under the sediment. Due to which event this happened, it is not yet known, but researchers say that if instead of being buried under the soil like this, they would have died normally, then their fossils would not have been found.
it was time for change
The site dates back to the Jurassic period (20–145 million years ago) when there was a period of sea change. More than half of the aquatic life died out in a catastrophic event at the end of the Triassic period, and echinoderms began to flourish. Arms came out of their bodies in sets of five, which used to catch the passing prey. Of these, creatures like starfish and sea cucumber used to go to the bottom and sea lilies stayed in one place and waited for prey.
