I visited a small Paleozoic (Silurian) coral reef in Indiana the other day. No earth-shattering, jaw-dropping discoveries, but it's an interesting spot with dolomitized fossils. Here's a google earth view of the center of the reef. A nice mollusk, if anyone knows what species, let me know. It shattered when I tried to extract it, but I was able to glue it back together as you can see here. Sphaerexochus romingeri cephalon After extraction.. I believe this is a Platyceras: To be continued..

Hello, I can't seem to ID this fossil found in Silurian reef rock, Chicago area. I made some slices. Any help appreciated.

A Devonian coral site in Louisville, Kentucky, USA

Hey all! First time poster. Found a few fossils along the Milwaukee River in Milwaukee, Wisconsin. Looking online, it appears this area was a Devonian Reef. I don't have a lot of experience in fossils besides plants, so any ID or commentary is helpful. A few of these I just found as pieces in big piles along a rock formation, I tried to put up a ruler for scale. For the one piece in situ, I didn't have anything handy, but it wasn't more than a few cm across. Thanks!

Recently I've been revisiting some local Silurian outcrops. I have a love/hate relationship with these outcrops as they are incredibly difficult to work with, however I secretly enjoy that aspect as well. The fossils represent the Homerian stage just before the Mulde Event, so roughly 422 - 426mya (if I'm not mistaken). For whatever reason, in the Racine formation, Gravicalymene celebra are almost always complete in the molting position and other species usually found disarticulated. The trick is extracting them without destroying them. Sometimes they are found enrolled, though much less common. I have only found two enrolled from this location over the past few years. 1) enrolled Calymene 2) Gravicalymene celebra 3) " 4) " 5) " 6) Sphaerexochus romingeri 7) Pentamerid brachiopod 8) favosites blastoid? 9) Dalmanitid pygidium 10) partial Dalmanites cephalon Close up snaps Sphaerexochus romingeri I believe this is a crinoid cup judging by the shape, but not sure. If anyone has any ideas... and the drum roll... Three species on one plate, Encrinurus pygidium, Dalmanites cephalon and a Calymene on the bottom . Unfortunately, due to the nature of the rock and my lowly prep skills, the only survivor is the Dalmanites. I somehow managed to restore both eyes with the original pieces for a nice "eye-popping" specimen. Thanks for looking . Also, in case you're curious, this entire collection is the result of four trips, not one. About 4-5hours per trip , so about 18-20 hours of collecting. and many more prepping. Cheers

Hi all just sorted out some old fossil and found this fossilised seabed. I found it 20 years in a river in South Wales can't remember where it was. This was before I was interested in fossils or natural history. The fossil over years is going a chalky lighter shade , if that makes any sense. What can I protect it with . Also what traces of fossils can you see in it. Kindest regards Bobby

Hello. I found this "thing" on the ocean floor while diving in the Philippines. It looks kind of like a tooth of a marine animal, probably not a shark. Any ideas?

I spotted an interesting fossil within a rudist reef of edwards group limestone near ozona, Texas Cretaceous Albian. This outcrop appears to be dolomitized Left of the chapstick cap. Thanks, George
