The Ediacaran Period /iːdiˈækərən/, named after the Ediacara Hills of South Australia, is the last geological period of the Neoproterozoic Era and of the Proterozoic Eon, immediately preceding the Cambrian Period, the first period of the Paleozoic Era and of the Phanerozoic Eon.
The Ediacaran Period's status as an official geological period was ratified in 2004 by the International Union of Geological Sciences (IUGS), making it the first new geological period declared in 120 years. Although the Period takes its name from the Ediacara Hills where geologist Reg Sprigg first discovered fossils of the eponymous Ediacara biota in 1946, the type section is located in the bed of the Enorama Creek within Brachina Gorge in the Flinders Ranges of South Australia, at 31°19′53.8″S 138°38′0.1″E / 31.331611°S 138.633361°E / -31.331611; 138.633361.
The Ediacaran Period overlaps, but is shorter than the Vendian Period, a name that was earlier, in 1952, proposed by Russian geologist and paleontologist Boris Sokolov. The Vendian concept was formed stratigraphically top-down, and the lower boundary of the Cambrian became the upper boundary of the Vendian.

Catching the second Ediacara wave: ecology and biology of the Ediacara Biota as recorded in South Australia Prof. Mary L. DROSER University of California, Riverside, USA Monday 11 July, 9:30 am – Inaugural Session – Ediacaran Mary was born in New York but spent summers as a kid playing in tide pools, fascinated by the marine invertebrates.

Although the rise of animal life on Earth has fascinated humanity for centuries, tracing its origins to an exact point in history has proven difficult. The Ediacara Biota—approximately 555 million years old—are recognised as the first known macroorganisms. Yet their assignment to the animal kingdom remains controversial, with some scientists believing animal life didn’t take off until the Cambrian “explosion”, around 20 million years later. New research conducted jointly by the University of Adelaide and the South Australian Museum, however, aims to resolve the debate. Comprehensive comparisons are being conducted between Ediacaran records and those from Kangaroo Island’s internationally significant Emu Bay Shale Cambrian fossil site, with findings tested against modern marine invertebrate...

'The Ediacaran Man' is the story of one of Australia's unsung scientific heroes. Geologist Reg Sprigg discovered that period in time about 500 million years ago when single cell life went multi-cellular, and he did it in a remote and arid region of South Australia. For years he fought against great odds to prove his work to be correct. This documentary is the story of Sprigg's life and his amazing discoveries. It is based on the book 'Rock Star: The story of Reg Sprigg - an outback legend' by Kristin Weidenbach.

The Ediacaran Biota and the development of modern marine ecosystems A Marine Life Talk at the National Oceanography Centre by Alex Liu Life in the modern oceans is abundant and diverse, but it hasn't always been that way. For almost three billion years following the initial evolution of life, the only inhabitants of the marine realm were microscopic, and largely microbial. Then, some 580 million years ago, large and complex organisms suddenly appear in the fossil record. Known as the Ediacaran Biota, these enigmatic and unusual life-forms, bearing little resemblance to any organisms seen before or since, seemingly dominated the planet for around 40 million years. This domination ended with the 'Cambrian Explosion' around 540 million years ago, when modern animal groups can first be rec...
From Snowball Earth to the Cambrian Explosion: recent research advances from China Prof. Maoyan ZHU State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, Nanjing, PR China Tuesday 12 July, 9:00 am – Cambrian Title: "From Snowball Earth to the Cambrian Explosion: recent research advances from China" Maoyan is a research professor at the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences (NIGPAS).

Mike Paulin, PhD of the Department of Zoology, University of Otago, New Zealand. Abstract: Suspension feeding and grazing animals with no nervous systems existed during the Ediacaran period, from c635Ma to the onset of the Cambrian explosion c543Ma. The two surviving Ediacaran phyla, poriferans and placozoans, have no neurons but can sense, recognize and move in relation to external threats and opportunities. Spikes are expensive -- they each cost about 106 ATP molecules -- so why buy a spiking neuron when you've been getting along just fine without them for 90 million years? Fossil evidence indicates spiking neurons evolved when animals started eating each other, about 550Ma. Unlike their predecessors who swept nutrients continuously from the environment, carnivores play an episodic gam...
Professor Derek E.G. Briggs, from the Department of Geology and Geophysics, Yale University, and Director, Yale Peabody Museum of Natural History told Tilde Cafe attendees about the remarkable information that is being uncovered in the last couple of decades, some which even includes information on soft tissue, shedding light on the Cambrian explosion, and also the Ordovician period.
The best documentary to watch high and sober. The Earth might seem solid beneath our feet but five billion years ago there was no sign of the planet we call home. Instead there was only a new star and a cloud of dust in our solar system. Over millions of years, a series of violent changes led to the formation of our world and, eventually, the creation of life. In this photorealistic CGI epic, see how a boiling ball of rock transformed into the blue planet we know today. Explore every aspect of our world; learn how water first arrived on Earth, discover the vital role oxygen played as life forms began to evolve, and find out how land mammals evolved into dinosaurs and other giant beasts, before becoming extinct 65 million years ago. Cutting-edge imagery also reveals how humans first bega...

I'm off on the road every night
Tryin'a grind to eat
And off on my stove, with' a light
Bustin' down a ki
If Baskin & Robin's got thirty-one flavors
Then I got sixty-two
My two newest flavors
Chocolate-wood, and pearly white blue
We got that green-kiwi baby
It's so sweet and delicious
And gaurunteed to get'cha high
Everytime ya lick it

We sold up all the blocks
We stack up all the rocks
We work around-the-clock

We keep 'em fresh
So let me tell ya how we cook them thangs
We get ounce of sugar
Mix it in a pipe
Add a cup of milk, some chopped ice
And keep it topped
We put it in the deep-freezer, let it hard rock
You gotta bust in on the floor, cause it's a hard block
Now get yo ice-cream scooper
So you can skeet them goods
And when you hit the hood
Keep yo hands up on the wood
