2 years, 9 months ago2 years, 9 months ago@shaun-rhoads and @smudge-smith I know I’m 11 months late, but the North American Buffalo, or bison, isn’t extinct. There are thousands that live in Yellowstone Park alone.

2 years, 10 months ago2 years, 10 months agoThank you for tagging me @smudge-smith ! Greetings @christy-olsen ! I concur the @smudge-smith that this is not a fossil. It does look like sandstone or a similar clastic rock that has been weathered into a unique by the current of the river. It does posses a pleasing aesthetic value, so I would at least keep it for that reason.

3 years, 2 months ago3 years, 2 months agoHi @chase-grim. I can see why you might think this is Lepidodendron. However, I’ve never seen one this small. I think @smudge-smith is right in that this is probably a sponge.

3 years, 2 months ago3 years, 2 months agoHi @rebecca-barnett and @smudge-smith. Where was this collected? Having the site can help narrow the ID because it can tell us what literature to look into if it has already been published. From a quick glance it looks like conifer leaves on a branch like @a-trilobite suggested.

3 years, 2 months ago3 years, 2 months agoHi @ryan-burns@smudge-smith. Wood is best ID’ed from the cross section but I don’t think this is wood. I see a lot of grains so I think this is just loosely compacted sandstone.

3 years, 2 months ago3 years, 2 months ago@chloe-geddes, @smudge-smith I agree with @jim-barkley. To add on to it a little more, this looks like a Mazon Creek nodule which puts it at about 309 Ma (mid-Pennsylvanian which is part of the Carboniferous). Mazon Creek nodules come from the Francis Creek Shale Member of the Carbondale Formation.

3 years, 4 months ago3 years, 4 months ago@smudge-smith it looks similar, but ammonites are all sorts of colors, many are smooth, and if it was a snail shell it would be hollow. I’m sticking with ammonite.

3 years, 5 months ago3 years, 5 months ago@smudge-smith there are quite a few creatures in Walking With Dinosaurs which are now known to have been smaller. like Liopleurodon, remember him? he was actually only about 7 meters long.

3 years, 5 months ago3 years, 5 months ago@smudge-smith it includes Quetzalcoatlus, who would probably be the big one on the left. it does not include Ornithocheirus though, which is in a different family. also, Ornithocheirus is now known to have been smaller than previously thought.
