Carnivore: A 3-foot-long creature with a monster-like chin.

"kdspe" and "kdspe" and "kdsps" bobit worms are colloquial terms of giant Euvies and marine worms that still exist today. These creatures can grow up to 10 feet (3 meters) long. They bury most of their bodies under the sand and wait for their prey to venture past, so that they can shoot out of the hole in a sneak attack. It is a new worm that lived in Devonian 400 million years ago. It only knows from its lower jaw that its length exceeds 0.4 inch (1 cm). On February 2 1 day, researchers reported in the journal Science Report that the size of the chin showed a huge number. [Photo: Ancient sea monsters are one of the largest arthropods]

"The huge size of animals is an attractive and ecologically important feature, which is usually related to advantages and competitive advantages," Matserikson, a paleontologist at Lund University in Sweden who is in charge of the research, said in a statement.

The dead metal worm fossils came from an isolated outcrop in Rabbit Ridge near Moosonee Town, Hudson Bay, Ontario, Canada. 1994, Derek Armstrong, a researcher at the Geological Survey of Ontario, came to the outcrop by helicopter and spent several hours collecting rocks. Since then, these samples have been kept in the Royal Museum of Ontario.

It is a giant marine worm 400 million years ago, named after a paleontologist and a late metal bassist. (Luke Parry) Examined three mudstone and strange stones, and found many jaw fossils, most of which were preserved as empty crevices, and the jaw had left traces in the mud before rotting. Some specimens also preserved a part of the original jaw, and the researchers wrote:

The characteristics of the jaw are "definite" with those of any known genus or species. They named this new animal Webster Ann Steni Ji. Armstrong pays tribute to those who collect fossils in the wild; Webster Roplin pays tribute to Alex Webster, the bassist who obituaries Man-eating Bodies. As the researchers explained in their papers on new species, Webster is a "giant" in bass, just as W.armstrongi is a giant in worms.

"In addition to our interests in evolution and paleontology, the three authors of this paper are all interested in music, and they are all music lovers," said Luke Parry, the author of the research report from Bristol University.

The unique giant Cubeba highlights its giant characteristics in Paleozoic. The researchers wrote that the specimens found in Ontario were probably buried by a sudden influx of sediments. They also say that worms may lose their jaws in their lifetime. The researchers wrote that although the jaw is consistent with the terrible ambush predator, this modern worm-called polychaete-has a variety of diets and eating habits, so W.armstrongi's lifestyle remains mysterious.

But it is clear that W.armstrongi is a contemporary heavyweight animal. Other worms from ancient polychaetes have jaws as long as 0.08 inch (2 mm). Eriksson said:

"This new species shows a unique case of polychaete gigantism in Paleozoic."
