The long, straight shell form is classic for Baculites, and the side views show the fossil’s original structure and natural edge texture. The end view highlights the internal chambering (septa), a key feature of ammonites and their relatives.\u003c\/p\u003e\n\u003cp data-start=\"432\" data-end=\"794\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eBaculites were straight-shelled ammonites that lived in the Late Cretaceous, drifting and hunting in the shallow inland sea that once split North America in two.
