Beautiful. Used to be able to hunt them all the time but don't have anywhere left to go. Congratulations.
I need someone’s cell number so I can send a picture of a piece I found years ago. Have no clue what it is but would love too. Message me and I’ll give you mine, I can’t post a pic here. Shawn
Posting these for Rockhousehunter:
These lost a lot of detail when resized. Someone else may have better luck with them but I think that is about the best I can do.
Thanks Mudd, I appreciate ya. Anybody have any guesses as to what this is. I've talked to tbob about it a little bit.
Im not trying to say for certain, but if the piece is perfectly cylindrical or nearly so it might be a piece of a drill core pulled from a from coal or other geological exploration. If you found it in coal country. I cannot tell enough about the thing from the picture.
found this awhile back (hide scraper )
Figured it out finally, how to post pics I mean.
Used to find a lot of leaf imprints in the fossils we broke out of drill cores. Similar to the things in your pictures. Specifically fern imprints like the top pic. Again, my best guess
Sounds reasonable to me. Does a drill core have the grooved lines going around them like this thing does?
Again, I cannot certify that is a core drill piece.
But Yes, there can be grooves , as it is a rotary metal drill that cuts the cores. Could hundreds/thousands of lineal feet of 2-3 inch diameter cores from the drilling; round cylindrical pieces that have been pulled in cores to the surface; and those core pieces will show every layer (dirt, rock, shale etc etc) for the length of the core that is pulled. (you can identify layers like some of those layer cakes in the food forum) .
Sometimes those cores are pulled in a solid 3+ foot piece or longer. Sometimes they stay solid for the length, other times they break at weakest layers. In the coal world they are trying to find an idea of seam thicknesses , type of strata overlaying the coal seams ( roof strength) and what strata types underly to coal seams . In surface mining old days you did not want to pay to move a huge amount of overburden and then find out the coal seam had pinched out or thinned out to an uneconomical mining ratio of dirt /rock to coal. So the core drilling went around the proposed mining area in advance of the dirt operation to make sure the coal/dirt ration conditions were profitable. Around old contour mining benches in pre-reclamation mined benches it is not uncommon to find stack of these cores laid out . Fossil hunters pick through them to find the shale pieces with good fern or other imprints. More than you wanted to know probably.
