I know next to nothing about radioactivity-- enough to know licking fossils is inadvisable, although I'll admit that wasn't terribly disappointing news. What I'm wondering is whether specimens not radioactive enough to endanger a person are capable of damaging other specimens. Is there a need to segregate displays here, or am I just confused about the mechanics of this? My specific reason for asking is that at the moment I'm planning for my current favorite mineral specimen (which I am babying forever), an almandine garnet from Broken Hill, New South Wales, Australia, to share a small shelf area with a tooth from the phosphate deposits in Oulad Abdoun Basin, Morocco and a few dinosaur bone pieces from the Hell Creek Formation of Montana (one from Dawson County) and Lance Creek Formation of Niobrara County, Wyoming. The shelf is not enclosed, by the way. Thanks for your help!

Hi TFF community, I recently purchased this small piece of Hadrosaur rib section originating from the Lance Creek Formation, Weston County, Wyoming. My question isn't to identify the Hadrosaur species (as its likely an Edmontosaurus sp. however if anyone can say with confidence then please do let me know!). My question is to ask if anyone can give more information or speculation towards what these curious scratch marks could be. The listing mentioned them possibly coming from a juvenile dromaeosaurid however I have my doubts based on the size of the markings but that's just my armature assumption. The markings show 3 scratches moving down the rib section, all of which are evenly spaces at 2.5mm away from each other and are in the classic theropod foot position. I've done some quick research towards the small flighted bird species that hail from the Lance Creek Formation but cant find much to match the size of these marks. I understand that these markings may also just be random damage that has been caused during the time this fragment has been buried, but opinion from others will be greatly appreciated. The fossil is 42mm x 24mm approx. I've also attached a microscopic look of the middle marking at 40x magnification if that helps. Thank you all for your time and help

Hi, I am considering to buy this tooth for my collection. According to the seller it is a Leptoceratops from the Lance Creek formation, North-Central Niobrara County, Eastern Wyoming. As I am not very familiar with such teeth I would like to check with you guys here. Thank you very much in advance for your help.

Hi again everyone Here is Bone likely from Hadrosaur (as far as seller told me) from Lance creek formation . It look like to be a partial section of Metatarsal bone ? what do you think guy??? Thank you in advance !
