"Half-Billion-Year-Old 'Terror Beast' Worm Fossils Unveiled in Greenland"

Scientists have discovered fossils of a giant carnivorous worm, Timorebestia koprii, in northern Greenland, which thrived during the Early Cambrian period over 518 million years ago. These 'terror beasts' were top predators of their time, reaching over 30 centimeters in length, and are related to modern-day arrow worms. The findings from the Sirius Passet fossil locality provide new insights into ancient ocean ecosystems and the evolution of carnivorous animals. The research, which also uncovered well-preserved anatomical details like digestive and nervous systems, was published in the journal Science Advances.
