Hello everyone I went on a commercial dino dig tour Summer 2022 of the Hell Creek formation in the Butte County, South Dakota area and found lots of bones and spitter teeth and had a great time. These two were in my unknown/unidentifiable pile and I've recently done some cleaning/prep to them and was requesting some help with possible IDs. The first item (on the left in most of the images) looks like a broken rooted ceratopsian/triceratops tooth to me with ridges and enamel showing. The second item (on the right in most of the images) looks a little like a scute with a raised round/circular area in the center and a lot of what looks like scratch marks on the opposite surface. I'm a newbie to the Hell Creek and these guesses may be off. Let me know if you would like any additional angles or detail for help with the ID. Thanks a bunch for looking

I'm rather embarrassed but i need some ID help on something I purchased a few years ago. My chagrin is because I usually am very good at labeling purchases or at least taking a pic of a label if the seller does not provide one. I have this piece of shale that has some fossil claw or fin marks on it that I recall are swimming traces. The shale comes from the Triassic or Jurassic of the Newark Supergroup in Pennsylvania. Any help is appreciated!

A new open-access paper asks if claws alone leave trace marks on bone. I would have thought this one was a given, but I guess it's still good to test it. Rothschild, B. Bryant, B., Hubbard, C., Tuxhorn, K., Kilgore, G., et al. 2013. The power of the claw. PLoS ONE 8, 9: e73811. Do members here have fossils that preserve marks attributable to claws? Let's see 'em!
