Examples of fuxhianhuiid had been found before, but not as well preserved

Scientists have found the fossil of the 520-million year old fuxhianhuiid. While specimens of this ancient creature have been found before, previous fossils were all found in the head-down position, with their delicate internal organs obscured by a large carapace or shell.

The discovery sheds light on how some of the earliest ancestors of today's animals may have evolved.

LOS ANGELES, CA (Catholic Online) - The fuxhianhuiid lived nearly 50 million years before animals first emerged from the sea onto land, during the early part of the Cambrian explosion. The recent discovery is one of the earliest animal fossils ever found, according to a new study.

The fuxhianhuiid has primitive limbs under its head, as well as the earliest example of a nervous system that extended past the head. The fuxhianhuiid 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.

"Since biologists rely heavily on organization of head appendages to classify arthropod groups, such as insects and spiders, our study provides a crucial reference point for reconstructing the evolutionary history and relationships of the most diverse and abundant animals on Earth," study co-author Javier Ortega-Hernández says. An earth scientist at the University of Cambridge, Ortega-Hernández said in a statement "This is as early as we can currently see into arthropod limb development."

Ortega-Hernández and his colleagues had begun excavating in a fossil-rich region of southwest China around Kunming called Xiaoshiba. The team unearthed several specimens of fuxhianhuiid where the bodies had been flipped before fossilization. Researchers had unearthed an amazingly preserved arthropod, as well as eight additional specimens.

These primeval creatures probably spent most of their days crawling across the seabed trawling for food and may have also been able to swim short distances. The sea creatures, are believed to be the earliest arthropods or jointed animals, probably evolved from worms with legs.

The discovery sheds light on how some of the earliest ancestors of today's animals may have evolved.

"These fossils are our best window to see the most primitive state of animals as we know them - including us," Ortega-Hernández said in a statement.

"Before that there is no clear indication in the fossil record of whether something was an animal or a plant - but we are still filling in the details, of which this is an important one."
