My Yearly Trip to Southern Iowa

[minnbuckeye]

It has become a yearly ritual to slip away to Southern Iowa to collect geodes. When in the area, I take an additional afternoon to play around in the Burlington limestone looking for crinoids but gladly accepting whatever comes my way. Here are some of my finds. Usually I label the pictures, but due to time constrains, I am posting unlabeled pictures this time.

 

I threw in a piece of styolith since I have seen a few topics where there was questions about what it was.

Nice haul, Mike! 

Very productive visit, lots of top quality finds, good lot of crinoids and brachiopods and I rather like those bryozoans as well! 

Thanks for sharing.

Exochops burlingtonensis  appears to be a good match with a pygidial rib count of at least 9 ribs on one of your partial specimens.

 

Congrats!
