The fossils, found recently in southwest China, are known as "bilaterians" because they are creatures with completely symmetrical, or bilateral, bodies, each with a front and rear, right and left sides, as all true animals have.

Scientists estimate the creatures were alive between 580 million and 600 million years ago -- more then 50 million years before the period known as the "Cambrian explosion," when within a few million years most of the major groups of animals first appear in the fossil record.

The microscopic oval-shaped creatures, looking like flattened turtle shells, are less than 180 microns long, barely the width of four human hairs.

Each has a mouth, an anus, and a pair of pits in its body that could have been sense organs capable of detecting changes in its environment, like light or darkness, said David Bottjer of the University of Southern California, a member of the Chinese and American team that made the discovery.

Your question is not well explained, the oldest death animal should be a fossil of a trilobite or something like that, and the oldest animal alive, may be the white turtle, they can live up to 200 years, GOD BLESS!

The oldest animal alive is, I think, a tortoise in Australia Zoo, QLD.
It was brought back from the Galapagos Islands by Darwin, so it is at least 175 years old.
Her name is Harriet.
