Praefectus Posted October 28, 2019 Share Posted October 28, 2019 I recently saw a few large ammonites for sale. The seller said the are ancanthoceras ammonites from Cretaceous Morocco. They are about 4-6 inches (10-15 cm) in diameter. Can anyone tell me if these are real and if the ID is correct? Thanks. Link to comment Share on other sites More sharing options...
connorp Posted October 28, 2019 Share Posted October 28, 2019 The interior whorls look like they might have been carved, especially the top left one. 1 Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted October 28, 2019 Share Posted October 28, 2019 These are common here. There are a few similar genera, this could be Acanthoceras. They have been ''enhanced'/ carved to ''improve the look of the inner whorls. I am assured by dealers they sell better to tourists like this. 3 Life's Good! Tortoise Friend.

Praefectus Posted October 28, 2019 Author Share Posted October 28, 2019 Thanks for the responses. I understand that the inner parts of the whorls are "enhanced" but are the outer parts real? Link to comment Share on other sites More sharing options...
Bobby Rico Posted October 28, 2019 Share Posted October 28, 2019 Keep looking and posting here. A lot of these ammonites have caved centres because it is quite common for them to be missing from preservation. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted October 29, 2019 Share Posted October 29, 2019 Yes, the main bulk of the ammonite is real, just in places carved to look better than it did naturally. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Ludwigia Posted October 29, 2019 Share Posted October 29, 2019 These are obiously carved in order to enhance the looks of what are in the end real fossil molds. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted October 30, 2019 Share Posted October 30, 2019 The umbilical (belly button) area is carved. The rest is natural (real). Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
