Researchers studying the soft-bodied Ediacaran biotas of the world generally accept that there are three distinct assemblages. The 575–560-million-year-old (Ma) Avalon Assemblage is best known from ...

A geological row is brewing over the first new geological period in 120 years to receive an official name. This month the International Union of Geological Sciences announced that its International ...

Evidence from biomarkers and molecular clocks points to the existence of sponges tens of millions of years before their earliest fossil remains. Fossils from South Australia may narrow that gap.

Owing to the lack of temporally well-constrained Ediacaran fossil localities containing overlapping biotic assemblages, it has remained uncertain if the latest Ediacaran (ca 550-541 Ma) assemblages ...

The 550-million-year-old fossil Tribrachidium heraldicum is one of the most enigmatic critters from the Ediacaran. With its circular, three-lobe form, it doesn't resemble any modern organism. The ...

Paleontologists have revealed the fossilized remains of a curious creature that is not only one of Earth's oldest animals, but may even be the first to have ever been mobile. Dubbed Quaestio ...

May 19 (UPI) --The Garden of the Ediacaran was livelier than previously thought, study suggests. Researchers believe several Precambrian species used currents to move and eat. Until recently, ...

Tribrachidium heraldicum, one of the most enigmatic critters from the Ediacaran fauna. A new study has for the first time precisely dated some of the oldest fossils in the world, helping to track a ...

Algae? Fungi? Some other type of plant? The Ediacaran organisms, ancient life forms that were common on in the Earth's oceans half a billion years ago, have puzzled scientists for decades. Now two ...
