Nice. Looks a lot like the Devonian stuff that we find in Michigan especially near Alpena (Jugglerguy's stomping grounds).

yeah the trilobites and crinoid stuff looks familiar for Michigan and Ohio Too. Those spiral ones are really cool. they remind me of some kind of pasta noodles.

I like going to Dale Hollow Lake when the water is down. There is some very nice agatized crinoid materal. Even the crinoids are agatized in places on the lake. They are a bluish-gray color. There is also places to collect geodes and other fossils. Haven't been in several years but it should still be a good place to go.

I used to see most of those when I was a kid spelunking in Tennessee caves. They were protruding out of the cave walls where the limestone dissolved away and left them exposed. And those do look like the Alpena fossils. Must be the same age. Those fossils much older from a much higher altitude ocean than the coral I find. But the bedrock is under the coral is made of micro fossils and much older than the coral, probably the same age as these Tennessee fossils. In Florida the old bedrock is precipitates of plankton,diatoms, algae etc. The spirals are archimedes bryozoans. cool

Nice stuff ... very cool of your friend to send those to you.
Looks a lot like the stuff I come across in Illinois.
