OVERVIEW OF EARLY LIFE ON THIS PLANET
Team of paleontologists says tiny creatures like the soft spongeliving at least 550 million years ago, nearly 10 million years earlierthan such a life form that supposedly never existed.
American scientists from the University of California Riverside said the soft-bodied organisms evolutionary transition into a reinforced-bones, marks a major innovation for the animal.
Fossil bones, discovered in South Australia, including type ofancient dwellers on the sea floor known as Coronacollina acula. The Latin name means "little hill framed needle."
Cone-shaped creature that seemed a portly size of about 3 to 5 cmin length, but there is such a thorn in his body like a needle, calledspicules. The team of scientists believe spicules are used to prop up the thimble-like animal, which was not able to move itself.
Team of paleontologists said they now know there are animals withbony body parts separately prior to the rapid changes in the well-known animals in the Cambrian period, from 542 to 488 millionyears ago. Coronacollina acula previously lived in the Ediacaranperiod.
Overall hundreds of fossil specimens that they found, according to scientists, it seems Coronacollina happy to live in groups.
According to the research team of University of CaliforniaRiverside, the discovery of Ediacaran fossil bones of the era thatgave new insights into the evolution of life, especially the earliestforms of life on this planet. This research report published in the journal Geology.
