Scientists have unearthed fossils of animals that are believed to have lived 520 million years ago. This fossil is a creature of the sea, which is the earliest animal fossils ever discovered by researchers.
Reported Nbcnews, Friday (01/03/2013), sea creatures or "monster" is called Fuxhianhuiid arthropods. It has a primitive limbs, the animals 'old' is the possibility of using his limbs to push the food into his mouth.
Animals moving past by way of crawling on the ocean floor could open up new horizons for researchers on the evolution of arthropods. Arthropods include crustaceans and insects.
"Our study provides an important reference point for reconstructing the history of animal evolution. Addition, the study also reveals the relationship of the animal's most diverse and abundant on Earth," said researcher Javier Ortega-Hernández.
He further said, this fossil shows into early arthropod limb development. These findings have been reported in the journal Nature.
Fuxhianhuiid believed to be living nearly 50 million years before the first animals emerged from the sea to the mainland. Paleontologists have discovered fossils Fuxhianhuiid previously, found the delicate internal organs are covered by a skin of magnitude.
"This fossil is a 'window' our best to look at the most primitive animals," he said. Before this fossil was found, he said, there is no clear indication in the fossil record of the evolution of animals and these findings represent an important thing.
