Scientists have recently discovered a rare and important hagfish fossil that involves the presence of protected waste 100 million years ago.
Stupid, fiery hugfish – still around today – strange, eil-like, carribean-eating fish that lick meat from dead animals using structures like their live tongue. But their most popular feature is sticky Kim which he fires for protection.
And now, scientists know that the bugfish virus is strong enough to release fossils in microbes, which detect significant evidence in fossilized hagfish skeletons dug in Lebanon. This new discovery is being inspired by the researchers to redefine the relationship between the hinges of animals with other ancient fish and all animals with backbones.

Hagfish fossils are unclear, and this template – an "obscure fossils hangfish" – is exceptionally detailed by preserving a soft tissue, scientists have reported in a study published in the National Proceedings of the National Education of Sciences today (January 21). PNAS).
The fossil era is up to the Cretaceous period (145.5 million to 65 million years ago), and the length is 12 inches (31 centimeters). Researchers named it Tethymicin tiporostem: Tethymicin "Tethys" (in reference to Tetheus) and from the Greek Latin word "méxininos", which means "delicate fish". Tepirostrome The authors of the study wrote that "translates as a tape snout" and that it refers to the elaborate nose of the fish.
Hagfish is around 500 million years old, although there are no signs of it as fossils, primarily because there is a lack of hard skeleton in their long, lean body, a major study author, Tatsuo Miishita, postdoctoral fellow of the Organonical Biology Department and Anatomy at the University of Chicago .
"Basically, it's like swimming sauce," Miyasta told Live Science. "It has many muscle-backed bags in it, there is no bone or hard tooth inside them, so it's really hard to save fossil record in them."
When threatened, modern haighfishes produce a kind of brain from special lymph glands shared with their body. Keratin Fibers – The material that makes our fingernails and hair – in respiratory encounter waters, they spread and expand shrimp globe to approximately 10 times its original size up to 10,000 times in a second study, published in a second study of research published in the journal Royal on January 16 Society Interface
Hagfish waste is a sticky mess that sticks to hunters by clamping their gills, and this weak defense is also effective on land, as many unfortunate motorists were learning in 2017. Fierce, Goo Haguefish trash temporarily closes the highway part of Oregon. Overturned a truck and dumped the hangfish payload – 7,500 pounds (3,400 kilograms) – on the road.
And now, scientists know that this loose conservation was made 100 million years ago, perhaps itchyrosis, placersaurus and ancient sharks are used to prevent cretaceous marine hens, Miyashita said.
PNASS study writers used the scratchotron scanning to investigate the Hagfish residue – a kind of imaging technique that bombes objects with highly energized and polarized particles – and they find chemical signatures of carotene fibers centered on more than 100 locations. Extract
His presence in fossil indicates that during this period, ancient Hagfish had already developed their soft superpower, according to the study.
Mian said that this rare discovery also gives a strange picture that this strange animal, garbage-producing fish is included on the tree of life, probably will help solve the scientific debate for centuries.
Hugfish is so odd that they have 'odd ones' on the fish family tree & # 39; As seen, the only residents of the lone branch, Miyashi said. Because their remnants are very small, it is unclear that long before the hangfish was separated from the common ancestors and they shared with all other fish (and then, all the millionaires).
But new fossils show that the 100f of hugfish was significantly similar to the Hufffish, which suggests that their special features are slowly accumulating over time. If so, instead of being more primitive "cousins" to other fish, the hugfish should be grouped with long-bodied lamps, as the study writers noted. Miyasta said, to clarify this relationship, scientists develop a more detailed picture of how backbones are developed.
He added, "How we think about our ancestors 500 million years ago, where we keep hugfish makes a difference."
