I live across the street from the Middle fork reservoir here in Richmond, Indiana and earlier today I was looking where the poor off is where the reservoir releases the water and it's a waterfall. I found this. I don't know what it is. Trying to get some help to figure it out

Any suggestions on this tiny bone? I found it while dissolving chunks of matrix from the lower Cretaceous Mackunda Formation collected in western Queensland, Australia. The matrix is rich in shells, crustaceans, fish and shark teeth but terrestrial species are known from the formation. It doesn't look like any of the fish bones I've seen from here so am considering bird? They've been found in the neighbouring Toolebuc Formation by @Mike from North Queensland so it seems possible! Thanks for any input:)

Yesterday I got home from a two week trip to Richmond, QLD where we collected from lots of different Early Cretaceous localities. I still have so much to go through and prep, photograph, etc. but here are a few things that I thought were worth photographing. A jewel beetle(?) from the Allaru Formation east of Richmond. I'm told this is the first Albian insect from Australia and the first from the Eromanga Basin, but there do seem to be a couple of other insects known from here (a dragonfly wing from the Toolebuc Formation and a scorpionfly wing). It was a really unexpected find since this site is known for things like bivalves, ammonites, belemnites, fish and marine reptiles. When viewing the rock it's in from the side it appears to be in between layers of Inoceramus. Will take some better photos with scale at some point but the specimen is about 15mm long. A plate of brittle stars from a property south of Richmond (Mackunda Formatiom) A really pretty shark tooth from the same location as the brittle stars. This is the only specimen I've seen from here with so many cusps. A small section of articulated ichthyosaur (Platypterygius australis) paddle bones from the Allaru Formation east of Richmond. Another from the same site as the previous specimen, a fish skull (Pachyrhizodus?). The other side of this specimen is still encased in limestone so I hope it will prep out well, this side is quite weathered. Will post some more tomorrow!

Last weekend I finally made my way up to the famous St. Leon road cut. Also known as South Gate Hill in some literature. I made the 2.5 hour drive to Lawrenceburg Indiana after work last Friday and stayed overnight so that I could be up with the sun and on my way Saturday morning. The site itself is another 20-30 minutes from the hotel. By 6am I was out the door and on the road. After a quick gas station stop I found myself at the mile long road cut. Most people come here to hunt in the butter shale of the exposed Liberty Formation for Flexicalymene rollers. I was no exception. Trilobites are not common in my immediate area so they were top on my list of things to find here. The butter shale is easy to spot. A creamy light gray layer exposed at the top of the second tier. I made my way there and following the advice of @Nimravis (Who sadly couldn’t make the trip to hunt with me. Missed you Ralph!) I got down on my hands and knees and put my nose to the ground. Most of the trilobites found here are quite small. The ones that I found were maybe a centimeter. I was lucky enough to come away with 2 complete rollers and 1 that was complete minus a bit of damage to the cephalon. Plus other trilo-bits. Including the usual Isotelus chunks found throughout the Ordovician of the area. A pile of Isotelus fragments. After I adjusted my focus away from trilobites I was able to see that the site had plenty more on offer. Brachiopods are everywhere here. I’ll let the pictures speak for themselves. Sorry for the lack of scale. The plastic ruler in the below picture fell out of my pocket very early in the day. I never found it. I can provide estimated sizes if requested, and will certainly have scale in the photos of the specimens I took home. This block was about a meter long. I found some nice examples of horn coral here too. Orthoconic nautiloids can be found here as well. Those were all the pictures I took from the field. All the ones worth sharing anyway. I stayed till after lunch, but all the climbing around and lack of food (forgot my packed lunch at the hotel )forced me away. After a bite to eat I also hit up a road cut in Lawrenceburg that I had read about. It was only 5 minutes from the hotel so I decided to check it out. The exposure was impressive in size, but not nearly as fossiliferous as St. Leon. Mainly consisting of Strophomenid brachiopods and some chunky bryozoans. Still I came away with a few finds and was glad that I took the time to look it over. The St. Leon road cut lived up to the hype and was well worth the visit. I definitely will be back. I’ve been short on time this week and haven’t gotten my finds that I brought home cleaned up enough for their photo shoot, but I plan on adding pictures of them as soon as I can as there was much more to see than pictured here. I also had plans to drive over to the AA highway, but I ended up having to head home earlier than expected. Oh well… Maybe that will be my next trip worthy of a report.

Found this fossil in my yard. I am located at the southern edge of the Cincinnati arch in Madison county Kentucky. Most of the rocks are Ordovician Limestone in this area. Can anyone tell me about this fossil?

On Dec. 31st, I had the opportunity to stop in Richmond, Indiana on my drive from Columbus, Ohio to Plainview, Mn. It was pouring rain with occasional claps of thunder when I arrived so I had to pull into Wal-Mart and purchase an umbrella before stepping out to look at the rock hillside. The finds were many, but I am not good at IDing this tubular "thing". There was one on each side of the rock. I did not see any more at this site. It was found in what I think is Whitewater Formation, upper Ordovician. Scaphite? Tentaculite? Tiny Cephalopod? Worm Borrow? Can anyone help to give it a name?? Thanks!! Mike

Found near Richmond IN. 2-1/4" long, 1-1/2" wide. I know it's rough, but it's definitely something. (The pictures don't do it justice) Any ideas?
