Cthulhu calls from the ancient depths – and this time researchers only gladly express their name.
Researchers from Yale University, Oxford, University of Leicester, Imperial College in London and University College London have identified fossil fuels for 430 million years as a new species associated with live sea cucumbers. They called the creature Solasin cthulhu, after H.P. The Lovecraft, Cthulhu, Monster Monster
The study, which was announced by the discovery, appeared on April 10 in the journal "Proceedings of Royal Society B". the bottom of the ocean and the delight of food. The creature was small, the size of a large spider. It was found in Herefordshire, Lahresthete, in the United Kingdom, a site that has proven itself as a treasure trove of ancient, ancient marine animals. and sea stars – with the preservation of which of the tissues, "said co-author of the study Yale's paleontologist Derek Briggs. – This new species belongs to the extinct group, called officioceticoids. With the help of high-resolution physico-optical tomography, we describe the species in 3D, revealing the internal elements of the aqueous vascular system that were previously unknown in this group and, indeed, in almost all fossil echinoderms. "
The 3D-reconstruction process involves grinding of minerals, layer-by-layer and photographing at each stage. This results in hundreds of snapshots that are digitally reconstructed into "virtual fossils."
Thus, the researchers were able to distinguish the inner Solasin water vessel system and to determine that it is more closely associated with sea cucumbers than with sea urchins.
"The aqueous vascular system manages the tentacular structures that they used to move and seize food," Briggs said. "The feet of the tube of live echinoderms are naked, but they are sown in officioisotheids.
Researchers argue that the existence of Solasin suggests that the skeleton of sea cucumber changed gradually during the compilation of the plan of his body.
