More than a century ago, paleontologist Charles Doolittle Walcott discovered some very strange fossils in Canada. This finger-sized animal was completely alien to what we have around us today. It looked like a lobster’s tail, had five eyes, and had a nozzle-like stem at one end. This 508-million-year-old creature courtwhich seemed like an isolated expression of an evolutionary riot dating back to the Cambrian period, before the mass extinction wiped out such oddities. It has been discovered that it has survived tens of millions of years longer than previously thought.
Last year, Harvard paleontologist Joanna Wolfe and her colleagues described the second specimen found so far. you will dreamFound in Utah, this creature obabinia and lived in the same era.But the day the discovery was announced, Wolfe saw a photograph taken by his research colleague Stephen Pates that would fundamentally change the history of these creatures. found 1 obabiniaWelsh rock-like creature about 40 million years younger than the first two specimens. This strange animal would have lived at a time when more modern-looking animals such as snails, cephalopods and corals were on the rise.
“My first reaction was that it couldn’t really happen,” says Wolfe. The fossils were poorly preserved and not immediately identifiable. However, the discovery and analysis of another, higher quality fossil revealed obabinia Finally persuaded Wolfe.She, Pates, and other researchers recently made the discovery Nature Communications.
At first glance, the new fossil resembles gray stone stains. But up close, they share some distinct features. obabinia. Wolf and her colleagues called animals Myeridulin (Welsh for “raspberry nose”) for its pointed proboscis.
It was a surprise to find such a specimen in Wales. “Fossils from the Landlin Dodwells area have been studied for decades, but were thought to contain only fossils of trilobite-like shells,” said the London Museum of Natural History. Paleontologist Rich He Howard said. No one was looking for small, soft-bodied creatures. Such fossils are invaluable in understanding the origin and early life of groups such as arthropods and their soft-bodied precursors.
Myeridulin We were alive during the Ordovician period because the Earth’s oceans were beginning to resemble something a little more familiar to us today. Various other Cambrian strange creatures are now known to have lived beyond the mass extinction into that new era. “There are a lot more questions now about how the opabinoids survived and what environments and life histories they were restricted to,” says Wolfe. It also has rocks that are 40 million years old.
