Fossilized Brains of Ancient 'Sea Monster' Discovered in Greenland
The discovery of not just one, but 15 fossilized brains from a 520-million-year-old marine predator is helping scientists understand how ancient brains evolved into the complex command centers they are today.
The creature in question, Kerygmachela kierkegaardi — a bizarre, oval-shaped water beast that had two long appendages on its head, 11 swimming flaps on each side and a skinny tail — isn't new to science, but its brain is, said study co-lead researcher Jakob Vinther, a United Kingdom-based paleontologist.
