'Terror Beasts': New Extinct Predators Discovered in Greenland

The Timorebestia, which lived over 500 million years ago, were among the largest swimming animals of their time and could provide insights into early animal ecosystems.

• Scientists have discovered a new group of extinct predators, nicknamed 'terror beasts' or Timorebestia, in Greenland.
• The Timorebestia, which lived more than 500 million years ago, were among the largest swimming animals of their time, growing up to 30cm in length.
• The creatures had a distinct head with long antennae and massive jaw structures, as well as fins on the sides of their body.
• The discovery is based on 13 fossils found in North Greenland, some of which contained evidence of food, specifically bivalved arthropods, called Isoxys.
• Experts believe that the Timorebestia were the dominant predators in the oceans before arthropods took over, and their discovery could provide insights into the evolution of early animal ecosystems.
