Hello, here is a larger! 100% natural Desmoceras Ammonite fossil that has been cut in half and polished on both sides! It has very well defined chambers with some being hollow and having semi translucent Calcite crystals!
This fossil was quarried in the old Tulear Province, Madagascar and dates from the Early Cretaceous Period a Crazy! 113 to 125 Million years ago.
They measure a nice! 8.02cm or 3 3/16" at their biggest or from opposing side to side. Please note that both sides are Included and they are WAY nicer in person as it is difficult to get all of the detail and true colors to show up in the photos!
