Cayr Posted January 2, 2023 Share Posted January 2, 2023 Hello, Can anyone identify this small fossil? Found on the shore of Lake Erie in western Pennsylvania, USA. Approximately .56 inch/ 1.42 cm each side. Thanks in advance! Link to comment Share on other sites More sharing options...
FranzBernhard Posted January 2, 2023 Share Posted January 2, 2023 This could be a water worn pebble of crystallized slag with nice dendritic crystal growth. Franz Bernhard Link to comment Share on other sites More sharing options...
Rockwood Posted January 2, 2023 Share Posted January 2, 2023 (edited) Some crinoids have an intricate filter basket of feeding appendages. Could this be an example ? Edited January 2, 2023 by Rockwood Link to comment Share on other sites More sharing options...
Ludwigia Posted January 2, 2023 Share Posted January 2, 2023 I'm also inclined to think that this is something originating from human activity. How does the substance feel? Pure stone or something else? Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Cayr Posted January 3, 2023 Author Share Posted January 3, 2023 Thanks for the replies! It's definitely made of stone and doesn't seem man made. It's very small and is not pottery of any kind. I have a degree in Anthropology, and while I'm not adept at identifying fossils, I have lots of experience with artifacts. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted January 3, 2023 Share Posted January 3, 2023 Silicon? Does it have a metallic luster? My goal is to leave no stone or fossil unturned.

Cayr Posted January 3, 2023 Author Share Posted January 3, 2023 No, it's not metallic. I did wet it for the first two pictures as it was easier to see the pattern when wet. It just feels like the same type of calcium carbonate stone as every other fossil I've found at the lake. I usually find coral- mostly horn coral. I've never found anything that looks like this before. Link to comment Share on other sites More sharing options...

Cayr Posted January 3, 2023 Author Share Posted January 3, 2023 No fizz! But two other fossils I tested did. Does that mean it’s likely slag? 1 Link to comment Share on other sites More sharing options...

Very good, you did also a control test! At least, the specimen in question is not composed of calcium carbonate. At the moment, I am still sticking to my interpretation that this pebble is some kind of water-worn, crystallized slag. Have you found any other slag, ceramic, pottery, glass etc. in that area?

Cayr Posted January 3, 2023 Author Share Posted January 3, 2023 A few small pieces of slag, but differently shaped- much thicker- and always a deep blue color. The only pottery I’ve found are pieces of broken china or pieces of basic red clay pots. I find beach glass, which is typical for Great Lakes beaches. 1 Link to comment Share on other sites More sharing options...

So it is not uncommon to find quite a variety of man-made stuff there. Such crystallized slags are usually(??) not super-abundant, but I have some greenish slags with cm-long, interlocking crystals, but not as regular as yours. Most slag from that same heap is glassy, though. Franz Bernhard Link to comment Share on other sites More sharing options...
Cayr Posted January 3, 2023 Author Share Posted January 3, 2023 Yes, there is quite a variety, but most falls into the category of garbage- especially the glass- broken bottles and dishes. Large number of animal bones and other natural things as well. I can see that there is some similarity with your pieces. I will say that this piece has such distinctive and textured surfaces, that it was easily spotted with the naked eye, even though it’s only 1.4 centimeters wide and I’m pretty old! There was industry in the area about 4 decades ago, but it was paper manufacturing, no steel furnaces anywhere near here I’m aware of. Thanks for your help! 1 Link to comment Share on other sites More sharing options...
abyssunder Posted January 3, 2023 Share Posted January 3, 2023 There are two possibilities in my thinking, one is geological the other is artifact.
