DiggerDawn Posted September 21, 2021 Share Posted September 21, 2021 Hi Everyone! I'm new here. My brother has had this in his collection since he found it in the early 1960's. Can anyone help me identify it? Found somewhere in Wyoming - probably in the Big Horn Basin area. Link to comment Share on other sites More sharing options...
Rockwood Posted September 21, 2021 Share Posted September 21, 2021 Shape of concretion, texture of chert. Is cherty concretion a thing ? @Carl What do you think ? One of our poop guys just in case. Link to comment Share on other sites More sharing options...
Coco Posted September 21, 2021 Share Posted September 21, 2021 I dont know what the paper on the side is, if it is used to guess the size it is missed ! For your future photos, PLEASE take a ruler and photograph it with your fossil. If you don’t have one, click on the last link of my signature, print the paper and put your fossils on it before making your photos I call @GeschWhat Coco 1 ---------------------- OUTIL POUR MESURER VOS FOSSILES : ici Ma bibliothèque PDF 1 (Poissons et sélaciens récents & fossiles) : ici Ma bibliothèque PDF 2 (Animaux vivants - sans poissons ni sélaciens) : ici Mâchoires sélaciennes récentes : ici Hétérodontiques et sélaciens : ici Oeufs sélaciens récents : ici Otolithes de poissons récents ! ici Un Greg...

Lone Hunter Posted September 22, 2021 Share Posted September 22, 2021 The paper appears to be a check of some sort judging by the signature on back, it would be 3 inches by 7 inches. Link to comment Share on other sites More sharing options...

No, no, you add the wood grain and divide by two to compensate for the variation in the size of each. Don't laugh, it is a valid concept to some degree with caveats. 2 Link to comment Share on other sites More sharing options...
