54 million years world’s most unique creature’s fossil fuel found! Have connection with humans

A study was done on the fossil of an organism of 54 million years old in China. Surprisingly, this creature was completely different. There was no back part of it, from where he could pass stool.

Its name has been named ‘Angry Minion’. Now according to a new study published in Nature, it has been found that this organism is not the ancestor of humans.

Member of deuterostomes

According to the ‘Daily Star report, when the research was first done in China, it was said that the 54 million-year-old micro-fossil named Sacorhytus coronarius was the first known member of the deuterostome species. A group of animals that are related to vertebrates like us. In such a situation, it was believed that it could be the ancestor of humans.

Part of arthropod species

However, researchers now say that this tiny creature from China is part of the same evolutionary group as arthropods, which includes insects and crustaceans. Philippe Donoghue, a professor at the University of Bristol and co-author of the study, says that earlier research suggested that Sacorhytus was an early member of our evolutionary lineage. A group of animals is called deuterostomes.

3D model identification

But we had specimens that were better preserved, so we knew immediately that earlier research had misinterpreted it, he said. The researchers now used hundreds of X-ray photographs and powerful computers to create 3D models of the creature, which helped them better understand its subtle features.

Size is one millimeter

Donoghue said Sacorhytus is only about a millimeter in size and looks like a small wrinkled ball with a tuft of thorns and rings of teeth around it. I like to describe it as an Angry Minion.

The first holes were called gills

The holes around its mouth were first interpreted as gill holes. However, closer analysis revealed that the holes were the bases of the backbone, which were broken during the preservation of the fossils. Professor Shuhai Xiao, a paleobiologist in the Virginia Tech College of Science’s Department of Geology, said that we are back in search of the oldest animal with a secondary mouth.

The mouth does all the work

However, scientists now believe that Sacorhytus is an ecdysozoan, a group that includes arthropods and nematodes. In the embryo of the deuterostomes, space is first made for bowel movement, which later becomes the mouth. Whereas, Sacorhytus has a hole, which acts as both.
