Exquisite fossils from the Ediacaran

| 2 Comments

The description of our site in the right sidebar says that “The Panda’s Thumb is the virtual pub of the University of Ediacara,” and the University of Ediacara (U of E) is “an online virtual University dedicated to the study of the origins of life in the cosmos.”

At the U of E site, Chris Nedin explains where the name “Ediacara” came from

The name “Ediacara” (pronounced Edi-ak-ra) comes from the Ediacara fauna, the first example of multicelled metazoans found in the fossil record. The significance of the fauna was first realized by geologists in South Australia, who found abundant fossils at the Ediacara Hills in the Flinders Ranges, about 650 km north of Adelaide. They realized that not only did the fauna contain jellyfish, soft corals and possibly worms and proto-arthropods, similar to modern forms, but that the fauna was significantly older than any other animal fossils yet found (600-540 million years old), even predating the Cambrian explosion. Whilst debate still continues as to the exact nature of the fauna, few now doubt that at least some of the forms represent examples of modern animal groups. The origin of the metazoa and thus all animal groups must now be placed even further back in time, and may never be found, since it is thought that the precursor organisms were miofaunal - tiny worm-like organisms living in the interstitial spaces between sand grains and thus having little chance of fossilizing.

“Ediacara” thus represents not only a major milestone in the history life on Earth, but also in the history of the Internet, being - as it is - the worlds first virtual university.

Apropos of this explanation, here’s a really neat story from the internet today. See here for the whole story and some neat pictures.

Great - this is the only post ever on the Panda’s Thumb with no comments!

But I fixed that, didn’t I. :)

Aw, Jack. I think they’re purty!
