Latest Anomalocaridid Stories
What?! A 500-million-year-old brain suggests that brains actually evolved before heads.
Anomalocaridids, the early ancestors of modern-day day shrimp, were massive creatures that grew to be more than six feet long and looked more like baleen whales than the crustaceans they would eventually evolve into, researchers claim in a new study.
An international team of scientists has identified the what they call "an exquisitely preserved" brain in the fossil of a group of animals known as anomalocaridids, or "abnormal shrimp."
Several large marine animals have evolved from fearsome predators to become gentle giants that use filtering appendages to ingest food, and new research has revealed a similar evolution in a group of predators that roamed the oceans 520 million years ago during the Early Cambrian.

Paleontologists working on fossils from Kangaroo Island in South Australia have discovered that the Earth's first apex predator had highly acute vision that rivaled or exceeded that of most living insects and crustaceans.
Hurdia victoria was originally described in 1912 as a crustacean-like animal. Now, researchers from Uppsala University and colleagues reveal it to be just one part of a complex and remarkable new animal that has an important story to tell about the origin of the largest group of living animals, the arthropods.
A missing link in the evolution of the front claw of living scorpions and horseshoe crabs was identified with the discovery of a 390 million-year-old fossil by researchers at Yale and the University of Bonn, Germany.
