Tim.shrek Posted November 7, 2018 Share Posted November 7, 2018 Hi All, hoping you can tell me what these may be from. Found near Hamilton, KY. I have included multiple pictures with a ruler as well. Let me know if you have any questions. Found on a creek. Link to comment Share on other sites More sharing options...
Kane Posted November 7, 2018 Share Posted November 7, 2018 I would guess that the first specimen is not a fossil, the second one is an intriguing impression that I can't quite make out, and the final one a significantly eroded "deer heart clam" (at least by appearance, as I am not intimately familiar with the formation from which this was collected). I'll tag @Herb on these. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Tim.shrek Posted November 7, 2018 Author Share Posted November 7, 2018 Thanks. The first two pics are the same one top and one bottom. The last three are the same as well. I never even hear of a deer heart clam until just now. Would they be porous as this one appears to be? Link to comment Share on other sites More sharing options...
DPS Ammonite Posted November 7, 2018 Share Posted November 7, 2018 The last rock is not a bivalve internal mold or dear heart. A close up photo might be revealing; a bone is possible. Does the rock fizz in acid? The top rock has possible shell. My goal is to leave no stone or fossil unturned.

Herb Posted November 8, 2018 Share Posted November 8, 2018 Possible bryozoan on shell fragment?? the other looks like worn rock to me.

Innocentx Posted November 8, 2018 Share Posted November 8, 2018 The first one is quite organized with shapes repeating along it's length. @Tim.shrek some close up photos of the surface of this one would be helpful in determining what it might be, if there are pores or striations or etc. "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...
Naf Posted November 8, 2018 Share Posted November 8, 2018 Does the first one feel like it could be clay? It sort of looks like a fragment, more specifically the bowl, of a clay pipe with a spur from sometime prior to the 20th-century. The ribbed design is a pretty common feature, but is usually found on the exterior; there were thousands of different regional variations though so its not an exact thing. http://suffolkarchaeology.co.uk/news/a-group-of-19th-century-clay-tobacco-pipes-from-college-street-bury-st-edmunds Link to comment Share on other sites More sharing options...
Tim.shrek Posted November 8, 2018 Author Share Posted November 8, 2018 Definitely not clay, feels like stone, but I believe it to be bone (but I could absolutely be wrong). The inside where the ridges are is concave, I have also attached a pic of what appears to be gnaw marks on it - but like I said this is stone like - I have found bones in the past but this is definitely not like it. I also took more closeups of the deer heart like thing. I was told someone found ground sloth bones and the like somewhere around there as well.

Plax Posted November 8, 2018 Share Posted November 8, 2018 Second item possibly the broken off and worn end of a large long bone. Link to comment Share on other sites More sharing options...
Innocentx Posted November 8, 2018 Share Posted November 8, 2018 @Tim.shrek. Your last group of photos are revealing a heart shaped bone fragment. The arrow points to foramen. This one probably an opening for blood vessel, maybe nerve. I still can't quite make out the other.

jdp Posted November 8, 2018 Share Posted November 8, 2018 Second item is the end of a long bone, probably a humerus, of a large mammal. First item is definitely bone, but I can't tell whether it is a chunk of jaw preserving the alveoli of the teeth or whether it is a synsacrum from a large bird, and the regularly-spaced ridges are sacral ribs. I would need to see somewhat better pics. But, both of these are vertebrate fossils, almost certainly Pleistocene in age. Link to comment Share on other sites More sharing options...

Thanks - I was thinking that was something along those lines, although I didn't know the terminology. (but now I do!!) Link to comment Share on other sites More sharing options...

Innocentx Posted November 11, 2018 Share Posted November 11, 2018 Hi @Tim.shrek. Sorry to bother you but I am still mystified by the smaller piece. Could you tell me if the areas marked with red dot are depressions or are raised up. Your other photo of it in different lighting seems to show a quite different orientation of depths. Thanks.
