For decades, scientists have puzzled over a significant gap in the fossil record of Earth's earliest animals, with genetic ...

Exceptionally preserved fossils from the Ediacaran period challenge what scientists thought was possible in sandstone. In the fossil record, creatures without hard shells or skeletons, such as ...

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 ...

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 ...

Scientists believe that the Earth is currently in the midst of its sixth major extinction event, but a new study suggests that’s not the case – it may actually be the seventh. Scientists have found ...

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, ...

In Earth's fossil record, soft-bodied organisms like jellyfish rarely stand the test of time. What's more, it's hard for any ...

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 ...

Figure 3: Isotropy plots from the H14 surface for each size-class of Fractofusus, providing a visualization of specimen positions relative to one another. As with other Ediacaran macrofossils, there ...
