Latest Ediacaran Stories
An unusual new fossil discovery of one of the earliest animals on earth may also provide the oldest evidence of muscle tissue – the bundles of cells that make movement in animals possible.
New three-dimensional reconstructions show how some of the earliest animals on Earth developed, and provide some answers as to why they went extinct.
Scientists at the University of California, Riverside have discovered a fossil of a newly discovered organism from the "Ediacara Biota" — a group of organisms that occurred in the Ediacaran period of geologic time.
The Cambrian Period is a time when most phyla of marine invertebrates first appeared in the fossil record.
Mysterious multicellular fossils believed to be ancient sea creatures may actually be some of the earliest land-dwelling organisms, according to a paper published online on Wednesday in the journal Nature.
Paleontologists have discovered the oldest organism with a skeleton in Australia.
The fossilized trail of an aquatic creature suggests that animals walked using legs at least 30 million years earlier than had been thought.
The rise of oxygen and the oxidation of deep oceans between 635 and 551 million years ago may have had an impact on the increase and spread of the earliest complex life, including animals, according to a study reported in the Proceedings of the National Academy of Sciences online Early Edition during the week of February 25 - 29.
By Shen, Bing Xiao, Shuhai; Dong, Lin; Zhou, Chuanming; Liu, Jianbo ABSTRACT- Upper Neoproterozoic successions in the North China and nearby Chaidam blocks are poorly documented. North China successions typically consist of a diamictite unit overlain by siltstone, sandstone, or slate.
Scientists interested in ancient life have a wealth of fossils and impressions frozen in rocks that they can study from as far back as 540 million years ago - when animals with shells and bones began to become plentiful. But evidence of complex life older than 540 million years is scant and difficult to study.
The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...
