"If true, these organisms would be among the first animals in the fossil record, dating back to at least 571 million years ago — the age of the oldest frond fossils. That's about 30 million years before the Cambrian explosion, when many of today's animal groups first burst onto the scene. The date is consistent with other evidence that suggests animals appeared more than 635 million years ago.

The mysterious frond fossils, which have been found around the world, date to the Ediacaran period, which spanned from 635 million to 542 million years ago. The fossilized imprints suggest that the organisms were soft and squishy and that some sported fronds that branched outward like seaweed, study co-author Jennifer Hoyal Cuthill, a paleobiologist at the University of Cambridge in England, wrote on The Conversation. Even 60 years after the discovery of these organisms, researchers (...)"

"Prof Valley's team was able to tease apart the carbon-12 from the carbon-13 within each fossil and measure the ratio of the two compared to a known carbon isotope standard and a fossil-less section of the rock in which they were found.

He said: "The differences in carbon isotope ratios correlate with their shapes.

"If they're not biological there is no reason for such a correlation. Their C-13-to-C-12 ratios are characteristic of biology and metabolic function," Prof Valley, said, based on this information, the researchers were also able to assign identities and likely physiological behaviours to the fossils locked inside the rock."

"the world’s oldest fossils, dating back some 3.77 billion years (and possibly as far back as 4.28 billion years). The remarkable find, detailed yesterday in the journal Nature, is comprised of a series of microscopic filaments and tubes that researchers believe were formed by bacteria that thrived on iron. If proven true, the fossils would be the oldest direct link to life on Earth—but not everyone is on board with the stunning discovery."

Previous evidence has suggested it took a long time for animals in the seas to bounce back."

"1.56 billion year-old fossils from China were multi-cellular organisms
Four distinct shapes of eukaryotes were found in mudstone deposits
Researchers think they probably used photosynthesis for energy"

"WHAT IS EUKARYOTIC LIFE?
Every complex organism living on the Earth is made of eurkaryotic cells from plants to animals and even fungi.
These cells have genetic material that is bound within a membrane along with other organelles such as mitochondria or chloroplasts.
They are thought to have first emerged on Earth when prokaryotic cells such as bacteria began incorporating other cells into them.
They were thought to have first emerged between 1.6 billion and 2.1 billion years ago but may not have started forming complex organisms until much later."
