Here's a few more.
These are crinoid stems, some branching corals and what-not, again found in the Imperial Valley, CA.
Some more corals. Many are highly agatized, and come in shades of white and yellow, to browns and purples. They have very distinctive patterns, and make beautiful (though small) slabs. Big enough for a single cab, anyway.
Three views of a section of branching coral, isolated from the host rock and polished. 7/8" long, 7/16" widest diameter.
Not sure on all of these. There are two bivalves, I believe they are called "kittens paws", the four to the right may be the ends of top fossil in next photo (whatever it is?!) Bottom center is a very flat, agatized snail, don't know what kind. Top left is a ball of fossils, and below that is a shell of some type.
Some of these are well preserved, with awesome colors and individual cells visible. I believe these are some type of coral? Maybe the top two are something totally different?
The grey one has been polished on the flat lap, the red one has been polished in cross section, so you can see the internal structure.
To the left is a not so well preserved echinoderm (Sea urchin, I think. You can see the bumps where the spines attached) from Painted Gorge area, further to the south near Plaster City. The top grey one is full of fusulinids. They are only about 1/4" in size, max, so you really need a loupe or magnifying glass to see the details. I will have to see if I can get some close-ups of this one. The ones on the right and center are unknowns, some type of small oblong critters, or eggs or? And the last one, I believe, is part of a crab claw.
Unsure what these are in the next two photos, but pretty sure they are some type of animal. They have a fibrous structure which tapers to a point at one end. When cut in cross section, it looks like a lot of pinholes.
I believe that these are a type of sponge. The top center one has been polished.
Again, thanks for looking! And if you would like to see a close up of any one fossil by itself, just let me know and I will do my best to oblige you.
