Paleontologists have analyzed the body profiles of Ediacaran-Cambrian organisms by using trace fossils as proxies for body fossils.
A reconstruction of...
Paleontologists have hypothesized for decades that a major animal group called Ecdysozoa must be older than the Cambrian period, but until now its origins...
Quaestio simpsonorum is part of the Ediacara Biota, which preserves the oldest evidence for complex, macroscopic animals.
Close up of Quaestio simpsonorum...
Geologists from Virginia Commonwealth University and elsewhere have found new evidence of bolide impact signatures within specimens from the Massive Australian...
An ultra-weak geomagnetic field between 591 and 565 million years ago (Ediacaran period) coincided with a significant increase in the oxygen levels in...
Paleontologists have examined how Tribrachidium, Rugoconites, and Obamus — three relatively common members of the Ediacaran biota (550 million years...
The oldest animals appear in the fossil record among Ediacaran biota communities. In new research, paleontologists from the Australian National University...
Mass extinctions are well recognized as significant steps in the evolutionary trajectory of life on Earth. In new research, geobiologists from Virginia...
Protocodium sinense is the first and oldest green alga species from the Ediacaran period (635-539 million years ago) to be preserved in three dimensions,...
The 635-million-year-old pyritized fungus-like microfossils found in the Ediacaran-period Doushantuo Formation in China provide direct fossil evidence...
Paleontologists have described the first three-dimensional preservation of soft tissue in Namacalathus hermanastes, a skeletal metazoan (multicellular...
Ikaria wariootia, a wormlike creature that lived more than 555 million years ago (Ediacaran period) in what is now Australia, is the earliest bilaterian,...
Paleontologists from the University of Missouri have discovered the well-preserved digestive tracts in the fossils of microscopic animals called cloudinomorphs....
Complex animals evolved from single-celled ancestors, before diversifying into 30-40 distinct anatomical designs. When and how this major evolutionary...
The first complex organisms emerged during the Ediacaran period (635-541 million years ago). Ediacaran fossils are as ‘strange as life on another planet’...
A team of paleontologists from the University of California, Riverside and the South Australian Museum has discovered the fossils of two soft-bodied animals...
According to a team of paleontologists at the University of Edinburgh, UK, the first complex animals lived millions of years earlier than previously thought.
Reconstruction...
Pre-Cambrian microfossils discovered in rocks in southern China hint that complex multicellular life may have appeared as early as 600 million years ago.
