Beautiful whole ammonite from Texas, USA. From the Cretaceous period, 100 million years ago. A great little collectors piece. Acanthoceras had ornate ribs on the shell, the function of which cannot be known, although one hypothesis is that they could have strengthened the shell, allowing the creature to live at greater depths with higher water pressure. Whatever the reason, this makes an attractive, affordable and fascinating addition to any collection.
