Monstrous 430 million-year-old sea cucumber discovered
Researchers have discovered an exceptionally well preserved fossil in 430 million-year-old rocks representing a new species of primitive sea cucumber, which they have named Sollasina cthulhu due to its resemblance to the sea deity from H. P. Lovecraft’s fictional universe.
“In terms of its morphological characteristics, Sollasina cthulhu was characterized by the presence of 45 tentacle-like tube feet, a body composed of many hard plates, and a mouth surrounded by five large ‘teeth,’” Imran Rahman, lead author of the study from the University of Oxford, told Newsweek. “We created the reconstruction through a process called serial grinding,” he said. “This involved painstakingly grinding away the fossil, a few hundredths of a millimeter as a time, taking photographs of each exposed surface with a digital camera. This allowed us to build up a dataset of hundreds of ‘slices’ through the fossil, which were then digitally reconstructed as a ‘virtual fossil’ on a computer.
