500-Million-Year-Old Sea Creature With Limbs Under Its Head Unearthed

Scientists have unearthed a stunningly preserved arthropod, called a fuxhianhuiid, in a flipped position that reveals its feeding limbs and nervous system.

 

Scientists have unearthed extraordinarily preserved fossils of a 520-million-year-old sea creature, one of the earliest animal fossils ever found, according to a new study.

The fossilized animal, an arthropod called a fuxhianhuiid, has primitive limbs under its head, as well as the earliest example of a nervous system that extended past the head. The primitive creature may have used the limbs to push food into its mouth as it crept across the seafloor. The limbs may shed light on the evolutionary history of arthropods, which include crustaceans and insects.
