Monster Mystery: Scientists solve the decades-long puzzle-like alien creature
#Cosmoread: In 1958, amateur fossil collector Francis Tully is very strange that the scientists also found a prehistoric creature called a monster. Some so-called animal “Tully Monster” is a worm and others calling it a shell-less snail classified as confused with researchers ever since.
But now, more than 1,200 Tully monster (Tullimonstrum gregarium) an analysis of fossils has uncovered the true identity of the monster. This is a 307-million-year-old jawless fish, a creature in the lineage leading to modern-day lampreys, the researchers found.
“This is a very unusual animal,” study co-author Scott Lidgard, Field Museum of Natural History in Chicago, curator of invertebrate paleontology.
In 1966 it is formally described by scientists, and in 1989, the Illinois state government designated it as fossils. But experts still could not make head or tail of it. They also have a race, a big picture about 30 broad category that includes subcategories, and nearly every living thing on earth could not place it in the original show.
Over the years, researchers have found thousands of specimens in Illinois Tully monster. Many of them digital, Field Museum scientists have been scanned into the electronic database, there are plenty of samples, while the new study was to examine the undertaking.
“In fact, no one knew what it was,” said study co-author Derek Briggs, professor of geology and geophysics at Yale University and the Yale Peabody Museum of Natural History curator of invertebrate paleontology, said in a statement. “Fossils is not easy to explain, and they vary
quite a bit. Some people thought it strange, maybe swimming molluscs. We decided to throw it all possible analytical technique.”
The researchers combed through the database and also the fundamental radiation mapping, a technique that uses a powerful light source within a fossil used to determine the chemistry.
Although soft-bodied, Tully Monster used its tail to a vertebrate that is likely to propel themselves in the water. In addition, the analysis showed that the “monster jawless fishes that are still around today with a unique combination of symptoms are associated with primitive gills [and] the rows of teeth,” said Paul Meyer, the Field Museum of Fossils invertebrates collections Manager, said in a statement.
It is also “marks a notochord, chordate animal that is present in the back with flexible rodlike structure – including vertebrates like us,” Mayer said.
Big eyes and pointy teeth of a predator fish was likely, study lead author Victoria McCoy, who conducted the research as a graduate student at Yale and now at the University of Leicester in the United Kingdom said. However, it is not clear when the animal becomes extinct when it was first developed, she said.
