Life in the Precambrian may have been much livelier than previously thought
Nashville TN (SPX) May 22, 2017
The Garden of the Ediacaran was a period in the ancient past when Earth's shallow seas were populated with a bewildering variety of enigmatic, soft-bodied creatures. Scientists have pictured it as a tranquil, almost idyllic interlude that lasted from 635 to 540 million years ago. But a new interdisciplinary study suggests that the organisms living at the time may have been much more dynamic than experts have thought. Scientists have found It extremely difficult to fit these Precambrian species int ... read more
