Finally scientist provide an Answer, What is Tully Monster, For more than half a century, scientists scratched Have Their Heads over the nature of an outlandishly bizarre creature dubbed the Tully Monster That About 307 million flourished years ago in a coastal estuary in what is now northeastern Illinois.But on Wednesday Researchers Announced They Have finally solved the mystery.
They Analyzed Numerous fossils of the creature, named Tullimonstrum gregarium, and it was determined to not a segmented worm or a free-swimming slug, as hypothesized eleven, but rather a type of jawless fish called a lamprey."I would rank the Tully Monster just about at the top of the scale of weirdness," Said paleontologist Victoria McCoy of Britain's University of Leicester, WHO Conducted the study while at Yale University.It boasted a torpedo-shaped body, and jointed, trunk-like snout ending in a claw-like structure studded with Two rows of conical teeth, and Its Eyes Were in September on the ends of a long rigid bar Extending sideways from the head. Up to About 14 inches (35 cm) long, it had a the vertical tail fin and a long, narrow dorsal fin.A sophisticated reassessment of the fossils was determined to it a vertebrate, with gills and a stiffened rod, or notochord, That functioned as a rudimentary spinal cord and supported ITS body.
The notochord with previously been identified as ADH the gut."I've always loved detective work, and in paleontology it does not get much better Than This," Said James Lamsdell paleontologist of the American Museum of Natural History in New York. "Our re-study of the specimens have shown That it is a very strange lamprey, a group of eel-like vertebrates That live in rivers and seas today."Tullimonstrum shared ITS shallow marine environment with fish as well as sharks Including jellyfish, shrimp, amphibians and horseshoe crabs."It fed by grasping things with the proboscis (snout) and scraping bits With its tongue off.
We do not know what it ate or if it was a predator or scavenger," McCoy Said.It is called the Tully Monster in honor of amateur fossil-hunter Francis Tully, WHO first found it in Illinois coal-mining pits in 1958 and Brought it to experts at the Field Museum in Chicago."This puzzle has-been gnawing at paleontologists," Said Field Museum paleontologist Scott Lidgard, Whose museum holds 1,800 specimens of Tullimonstrum, the official state fossil of Illinois. "I was blown away When the results started coming in."The research was published in the journal Nature.
