Found this at Railroad Buttes today. To me, it really looks like dino bone, but I'm in whatever category of rockhound is "below" novice! If anyone can help me ID this, you'll help with a mystery as deep to me as Darryl (aka Bigfoot)!

It looks like conglomerate - small quartz pebbles cemented by calcite, iron oxide (yellow to orange colour?) or silica.

Could also be a fossil. Coral or sponge base. I have similar pieces that the local natural history museum director identified for me. He said they were the base, AKA, unseen part of the coral/sponge. Basically the roots. Another thought is Spotted Chalcedony. The two are very similar.

Basically the roots. Another thought is Spotted Chalcedony. The two are very similar. The corral base is an interesting thought as well. I did find it in the same location as several horn corral. Three horn corral on the same little hillside - that's a first for me to find that many so close to each other. Not that those came from this particular base necessarily, if it is a base. However it would put the two types of fossils in very close proximity to each other as this was found on the same hillside...

(My wife talked me into going...not the other way around! ) These two I would definitely say are conglomerate. I'm sure you're probably right on the first one as well, but it just looks completely different than these two. All three were picked within a hundred yards or so of each other.

I guess we both had a similar experience, however I was like "cool!", and ate it right up

I guess we both had a similar experience, however I was like "cool!", and ate it right up Yeah, normally I had no problem eating "gross" things...my favorite book as a kid was "How to Eat Fried Worms!" for gosh sakes! LOL But for some reason, that one struck a chord and I just couldn't get over that particular thought. LOL

Frogs were everywhere in Pierre SD when I lived there as a child.
Perhaps my childish mind thought I was eating the frog's eggs and reducing their population... Who knows. Glad I'm an "adult" now (sorta)
