New Members low temp geochemistry Posted 3 hours ago New Members Share Posted 3 hours ago I've been pondering this for a year. Any help with an ID? From mid-cretaceous Duck Creek formation in west Tarrant County, TX, US. Large pentagonal sutured surface pattern. Found in an extensive construction excavation. The segment arc section would make a huge ammonite and atypical in the formation. Typical 'large' ammonites >3-4' diameter are common. Link to comment Share on other sites More sharing options...
