Bob Saunders Posted November 23, 2020 Share Posted November 23, 2020 A new edition to my collection. I was told that the original finder of this item listed it in his journal a Rhaeboceras Sp. and the seller said her source could not find it listed. A check of the internet proved it be an ammonite. Location matches his journal entry. SPECIES Rhaeboceras halli AGE Late Cretaceous - Upper Campanian Stage View on Geological Time Scale LOCATION Rosebud County, South Montana FORMATION Bearpaw Shale SIZE 2 1/4 " wide 5.8cm x 1 1/4 inch thick. CATEGORY Ammonite Fossils Link to comment Share on other sites More sharing options...
FossilDAWG Posted November 23, 2020 Share Posted November 23, 2020 I don't want to be a wet blanket, but I don't see anything here that says "ammonite", much less presenting enough detail to be able to assign it to a genus or a species. Sorry! Don 3 Link to comment Share on other sites More sharing options...
Bob Saunders Posted November 23, 2020 Author Share Posted November 23, 2020 Thanks, I told her it looked more like a turtle shell. But for $8 I decided to take it. That is a problem with estate pieces and it very well could have came from that location as he noted. Link to comment Share on other sites More sharing options...
