Interesting, l'emmy. Apparently Foraminifera classification became important to geologists trying to make sense of layers of sedimentary rock that might contain oil. Of course, there are also many extant forms - Dad used to sample the top layer of mud in local bays - he would use a dye which stained their protoplasm pink, so he could spot the living ones in the sample...

That's really cool Jim. :cheers: I didn't get a chance to look at them in lab. We did look at the related diatoms which are also cool.

Check out Radiolarians as well - they have amazing silicon shells...

Who needs religious delusions when life on Earth, both past and present, has millions of examples of awesome?

Oh yeah, the Radiolarians are nice. I enjoyed watching Euglena swim around. But when it comes to truly bizarre and fascinating protists, I'm going with the Amoebozoans, and the slime molds specifically.

You don't get many Myxomycete fossils though.

Why are papers from 1992 still behind the pay-walls of multiple archive sites that also want to force you to accept cookies simply to search their lists?! :lay:

Take this YECs...

'Mindblowing' haul of fossils over 500m years old unearthed in China
Image

A “mindblowing” haul of fossils that captures the riot of evolution that kickstarted the diversity of life on Earth more than half a billion years ago has been discovered by researchers in China.

Paleontologists found thousands of fossils in rocks on the bank of the Danshui river in Hubei province in southern China, where primitive forms of jellyfish, sponges, algae, anemones, worms and arthropods with thin whip-like feelers were entombed in an ancient underwater mudslide.

The creatures are so well preserved in the fossils that the soft tissues of their bodies, including the muscles, guts, eyes, gills, mouths and other openings are all still visible. The 4,351 separate fossils excavated so far represent 101 species, 53 of them new.

“It is a huge surprise that such a large proportion of species in this fossil assemblage are new to science,” said Robert Gaines, a geologist on the team from Pomona College in Claremont, California. The fieldwork was led by Xingliang Zhang and Dongjing Fu at Northwest University in Xi’an, 700 miles (1,127km) south-west of Beijing.

The fossilised organisms date back to 518m years ago when life on Earth experienced a massive burst in diversity known as the Cambrian explosion. The event, at the dawn of animal life, marked the arrival of all manner of unusual creatures. Many went extinct as evolutionary dead-ends, but others went on to form the first sturdy branches of the tree of life...

So far, researchers have identified 101 animal species in the remains, and more than half of them are brand-new to science.

Just goes to show that science once again has no idea what is has found. This is yet more proof of the great flood described in the bible. How else could these sea creatures end up on land?

I think God must've placed YECs on Earth to test my patience.

I think they were originally intended as comic relief, but things got out of hand.
Yeah well that's just, like, your opinion, man.

Bone is apatite and organic matter. The organic marrow obviously decomposes

Calcite
https://english.fossiel.net/information ... %20fossils
The early thinking was that bone turned to sedimentary rock. But this is because bone has a lot of empty space filled with tiny pockets of matter. It turns out that the bones do get heavier, but original apatite (calcium phoshate) remains.
