Texas Ammonite Fossil Mortoniceras 5 1/2 inches Natural Gray visible sutures

Description

Texas Ammonite Fossil Mortoniceras 5 1/2" inches Natural Gray visible sutures.
Rare Specimen from the time Dinosaurs walked the earth.
This is a nice size ammonite called Mortoniceras.  It is approximately 105 million years old.  Ammonites became extinct at the end of the Mesozoic Era along with the dinosaurs, pterosaurs, and marine reptiles.  Ammonites get their name from the coiled shell shape being reminiscent of a ram's horn. As the animal grew it created more shell, living only in the very largest part of the shell.  As newer parts of the shell were created the older sections were sealed off with septum, or walls that connected to the inside of the shell.  This connection creates sutures or patterns on the fossil that are distinct and can be used to identify various fossils.
This beautiful specimen comes from the Upper Albian Stage, Cretaceous Period, Duck Creek Formation in North Texas. At one time this area of Texas was a shallow ocean where these ammonites and other aquatic creatures thrived.
It has an nicely defined spine, great ribs and tubercles. Displays beautifully.  It is a very desirable gray color.
