FossilHunterNYC Posted July 26, 2020 Share Posted July 26, 2020 Found a bunch of these in Lake Texoma. Ammonites but can you tell the age or species ? How hard is it to find a whole one over there in Lake Texoma, TX. Can I clean some of them up ? Link to comment Share on other sites More sharing options...
DPS Ammonite Posted July 26, 2020 Share Posted July 26, 2020 (edited) They are from the Cretaceous Duck Creek Formation. The ammonites with the widely spaced ribs and marked with yellow are Eopachydiscus marcianus. The others are probably Mortoniceras. Locals might give better ID on the non Eopachydiscus ones. Clean them up with warm soap, water and a plastic/bristle brush. Small complete ammonites are much more common than the large ones. Most large ones have cracks or are partials. See Hall’s northtexasfossils.com website where attached photo of a Eopachydiscus marcianus is from. http://northtexasfossils.com/ammonites.htm Edited July 26, 2020 by DPS Ammonite 2 My goal is to leave no stone or fossil unturned.
