Hope it is sciencey enough for you.
>>So far, says Gehling, about 60 genera and a couple of hundred species of Ediacara flora and fauna have been found on every continent except Antarctica. They have very distinctive patterns, some of which are similar to those of Cambrian fossils.
“Others look like nothing we’ve seen since,” he says.
Many appear to be quite flat, shaped like leaves, fronds or mats. This could be because they were indeed flat — maximising their surface area and the amount of oxygen and nutrients they could absorb from seawater.
But it could also be the case that their soft body did not allow their three dimensional shape to be preserved, says Gehling.
Some scientists have characterised Ediacaran fossils as failed experiments in multicellular life but Gehling rejects this idea.
“I particularly hate that phrase,” he says.
Gehling points to Dickensonia — the creature first identified by Sprigg — found in multiple fossil beds throughout the Flinders Ranges as well as in Russia.
“They were enormously successful by any measure in the sense there must have been billions of them in the ocean in the Ediacaran,” says Gehling.
Yes they went extinct, he says, but that’s no reason to write them off.
“You wouldn’t call dinosaurs a failed experiment,” says Gehling.
