Hyolitha, a rather strange animal, covered in a shell, this animal, witnessed the Cambrian period, also known as the “explosion of life”, which in turn gave birth to various species of animals.
This animal lived on the seabed some 500 million years ago. And it was, at first hand, a witness to the Cambrian period, the so-called “explosion of life”, which suddenly originated several species of animals. This finding was made after it had been determined that hyolitha did not belong to Family of mollusks, but rather to the group of lofoforados, which are invertebrate animals that use tentacles to feed themselves, the BBC reports.
This marine creature acquired its place in the tree of life thanks to a study published by the journal Nature, which was attended by paleontologists from the University of Toronto. “They [hyolitha]appeared in the fossil record about 530 million years ago, and survived up to 250 million years ago.
However, its origin has been unknown for 175 years, when they were discovered, “said Joseph Moysiuk, one of the scientists responsible for the discovery.
“Finding out that we can position them in the tree of life solves the long mystery about what these animals really are and what their origin is,” Moysiuk told the BBC.
According to the scientist, the unusual anatomy and incomplete history of these creatures were the great barrier to the discovery of the true animal group to which they belong.
According to El Mundo, research from the analysis of the soft tissues of the species revealed that they used a pair of large, curved structures to manage to rise to the surface of the sea.
The experts also consider that this work came to create a paleontological debate and to emphasize the importance of soft tissue preservation to solve the evolutionary history of other species.
