I found this along the Whitewater River in Southeast Indiana and trying to id looking at my book. I'm a newbie and trying my hand at prepping using a needle vise, but the more I uncover the more I find. Wondering if you could shed some light on what all is in this "rock". Thanks so much, meanwhile I'll keep pecking away and try to clean this up a little more!

On this dreary first day of the New Year, I was poking around in some of the fossils I picked up on the Whitewater River in Franklin County Indiana and trying to id them. The fossil on the right hand side is shaped like a Horn Coral which I find alot but it shares the same crenelated surface as the fossil in the middle which isn't shaped like a Horn Coral. Could the middle fossil be Cystiphylloides? The piece on the left I have no clue, it's really porous and may be just a rock, but I see a small mold of a shell in it? Appreciate you help and want to wish everyone a Happy New Year!!

Last week, after checking the weather wunderground numerous times, I decided to drive 3.5 hours from Chicago to St. Paul Stone Quarry. It was the last "open house" day according to the ESCONI website. I arrived at 7:45, the first and only person there. Shortly thereafter, after a brief safety instruction, I followed the manager to the collecting site, heaps and heaps of Waldron shale. Even though I dressed in layers, I still had to take breaks and warm up in the car for a few minutes, but I much rather prefer collecting in cold weather as opposed to hot summer sun with mosquitoes, any day. It didn't take too long to start finding fossils. Here are just a few of my finds: Eospirifer Platystrophia brachiopods with pyrite Platyceras niagarense encrusted with strophomenid, bryozoa and pyrite. front: back: Partial Dalmanitid Trilobite in matrix When prepping, it's really wonderful how the waldron "butter" shale just crumbles apart around the predictable morphology of an enrolled trilobite. The trip just wouldn't seem complete without a short drive east to the Cincinnati Arch roadcuts. I first went to South Gate and found a flexicalymene eroding right out of the cut. It is interesting to see the comparisons here. The trilobite on the left is from St Paul (Silurian) and has beautiful pyritized eyes. The one on the right is from South Gate (Ordovician). Both trilobites have 21 articulated segments; does this make them both the same age as "adults"? Interesting to note the difference in size, being 40 million years apart, same species.. Thanks for looking!
