I think we need a fossil thread for posting articles about new discoveries and important older ones. In recent years there have been a number of new Cambrian and Precambrian fossil deposits discovered and many new species described.

It would be great to see discussion, but hair-brained debate is pointless.

New 'king' of fossils discovered on Kangaroo Island

quote:
"We decided to name this new species of trilobite Redlichia rex (similar to Tyrannosaurus rex) because of its giant size, as well as its formidable legs with spines used for crushing and shredding food—which may have been other trilobites," says James Holmes, Ph.D. student with the University of Adelaide's School of Biological Sciences, who led the research.

The preservation of trilobite soft parts such as the antennae and legs is extremely rare. The new species was discovered at the Emu Bay Shale on Kangaroo Island, a world-renowned deposit famous for this type of preservation. The findings have been published in the Journal of Systematic Palaeontology by a team of scientists from the University of Adelaide, South Australian Museum and the University of New England.

Good idea - Will promote to new topic and pin
I try to avoid having a bunch of micro "Links and Information" topics, but having one focused on new fossil discoveries seems to be a good idea.

Going to promote to "Links and Information" forum and pin the topic in the "Links and Information" forum index.

Perhaps members could mine past new fossil discoveries from past topics and plug into this new topic.

Remember - "Links and Information" topics are NOT for debating the link's content. For such, a new "Biological Evolution" topic is called for.

Or something like that©.

Two New Fossil Fungi Discoveries
Two stories about fossil fungi that I ran across a while ago.

One billion year old fungi found are Earth's oldest

quote:
Scientists have unearthed fossilised fungi dating back up to one billion years, in a discovery that could reshape our understanding of how life on land evolved, research showed Wednesday. For decades, the earliest known fungi—organisms such as mushrooms, mould and yeast—was thought to have appeared on earth around half a billion years ago.

But recent fossil specimens unearthed in Canada and analysed using the latest dating technology appear to push back fungi's arrival to the earliest reaches of life on land.


Fossils may be earliest known multicellular life: study

quote:
Fossils accidentally discovered in South Africa are probably the oldest fungi ever found by a margin of 1.2 billion years, rewriting the evolutionary story of these organisms which are neither flora nor fauna, researchers said Monday. If verified as both fungal and multicellular, the 2.4 billion-year-old microscopic creatures—whose slender filaments are bundled together like brooms—could also be the earliest known specimens of the branch of life to which humans belong, they reported in the journal Nature Ecology & Evolution.

quote:
Up to now, the first fossil trace of eukaryotes—the "superkingdom" that includes plants, animals and fungi, but not bacteria—dates to only 1.9 billion years ago.

Earth itself is about 4.6 billion years old.

The ancient fungus-like life forms, found in fossilised gas bubbles 800 metres (2,600 feet) underground in South Africa's Northern Cape Province, are remarkable not just for their age but their origin, the researchers said.


quote:
It screamed 'life'

"My attention was drawn to a series of petrified gas bubbles, and when I increased the magnification of the microscope, I was startled," he recalled.

The bubbles were "filled with hundreds of exquisitely preserved filaments that just screamed 'life'," he wrote by email.

The plot thickened when Rasmussen realised that the surrounding lava was not 2.2 billion years old, as previously thought, but 2.4 billion years old.

That extra 200 million years was significant because it straddles a critical threshold in Earth's geological history called the Great Oxidation Event—a rapid and massive outpouring of oxygen into the atmosphere.

Re: Two New Fossil Fungi Discoveries
So if humans evolved from fungus why do my toes still itch?

Edited by Adminnemooseus, : No reason given.


Eschew obfuscation. Habituate elucidation.
