Fossil hunters discover a giant lair of a predatory worm



Paleontologists at the National Taiwan University believe that at a depth of 6.5 feet it was once home to a worm-like predator that will emerge from the seabed to plant sea creatures and drag them alive into its lair.

Experts working in northeastern Taiwan have reconstructed large L-shaped holes from 23 million years ago from seabed layers using fossil traces – geological features such as traces of traces, holes and cavities of plant roots found preserved in rocks that experts used to draw conclusions about the behavior of ancient beings.

Using 319 specimens, the experts reconstructed traces of fossils of dugout – called Pennichnus beautiful!

; which was 6.5 feet long and about an inch in diameter and is said to have morphological evidence that the tunnels were home to giant sea worms, such as the modern beetle worm.

The eunice aphroditois is an aquatic predatory worm that ranges in length from 4 inches to 10 feet and lives in burrows that it creates in the ocean floor. The bobbin worm takes its name from the case of Lorena and John Wayne Bobbitt, in which Lorena cuts off her husband John Wayne’s penis with a kitchen knife.

Living mainly in the Pacific Ocean, beetle worms hide in long, narrow holes in the seabed and move up to catch unsuspecting fish, large mollusks and other worms before pulling them, still alive, back to their dens.

In a study published in the journal Scientific Reports, the report’s authors note that the withdrawal of an ancient worm and prey into the sediment could have caused “feather-like” structures preserved in Pennichnus formosae.

They found a high concentration of iron in the upper part of the hole and believed that the worm could have released mucus to strengthen the wall of the hole.

“We hypothesize that about 20 million years ago, on the southeastern border of the Eurasian continent, ancient bobbit worms colonized the seabed in anticipation of an ambush for transient food,” the report said.

“When the prey approached the worm, it exploded from its burrow, grabbing and dragging the prey down into the sediment. Under the seabed, the desperate prey escaped to escape, leading to further disturbance of the sediment around the hole,” they described.
