Huntonia lingulifer fossil trilobite from Oklahoma

Huntonia Trilobite Facts and Information

Huntonia trilobites have an interesting look. They have a "snout" on the front of their cephalon, they have large, round, eyes that stick up from the cephalon, short genial spines, and a pygidial spine (tail). The main difference between the more rare Huntonia lingulifer and the more common Huntonia huntonensis is that H. lingulifer has a much longer pygidial spine.

Huntonia trilobites can range in size. Many found are between 2 and 3 inches. They can however reach sizes that approach 6". Bob Carroll had been prepping a few that were well over 5" in length when we were there.

Based on the shape of the trilobite, it roamed the bottom of the sea floor, possibly hunting or scavanging.
