Fossil hunters find giant hunter lair

National Taiwan University palaeontologists believe that this 6.5-foot-tall turret was once a worm-like predator, which ambushed seas from the seashore and drew sea creatures, taking them alive.

Experts working in northeastern Taiwan reconstructed large-sized L-shaped bridges up to 23 million years ago from the seas using trace fossils – track marks found in rocks, burrows, and root cavities of the plant. The kind of geological features that experts use. To conclude on the behavior of ancient beings.

Using 319 specimens, experts reconstruct a trace fossil Dugout – Dub Penichanus Formosse – which was 6.5-feet long and around an inch in diameter, and morphological evidence suggests that the tunnels were home to giant marine insects, like modern marine insects.

Bobbit worm, or sand striker (Eunice aphroditis), is an aquatic predator Bristol worm that ranges in length from 4 inches to 10 feet and lives in the burr that forms it in the seabed. The bobbet worm takes its name from the Lorena and John Wayne bobbit case, in which Lorena cuts off her husband John Wayne’s penis with a kitchen knife.

Living primarily in the Pacific Ocean, bobbet insects hide in long, narrow platforms in the ocean and move upstream to pull out unsuspecting fish, large mollusks and other worms, before they can be pulled, still The living, return to their dense part.

In the study published in the journal Scientific Reports, the report authors noted that retreating of an ancient worm and hunting down sediment may have preserved a “wing-like” structure in Penichus formosae.

They identified a high concentration of iron in the top part of the burr, and believe that the worm may have secreted mucus to strengthen the debris wall.

The report authors wrote, “We estimate that about 20 million years ago, on the southeastern border of the Eurasian continent, ancient bobet insects colonized the seafloor sitting ambush for seafood.”

“When the prey came close to a worm, it came out of its burr, taking the prey down and into the sediment. Beneath the seafloor, the desperate prey instigated the escape, causing further disturbances of sediment around the Buru opening. . ” He described.
