Ventral Utaspis Showing Hypostome

Here is a rarely seen ventral example of Utaspsis marjumensis from the Marjum Formation of Utah. Utaspis are highly sought after by collectors. While it's missing a section of the tail the shell preservation is excellent, and it's nicely articulated. The hypostome or mouth plate of this trilobite is visible.

Utaspis is a scarce trilobite is not seen that often on the market. You can dig days without finding a good complete example. The interbedded shales and limestones in which they are found take a lot of effort and skill to work. This one was personally collected and prepared from a private lease in the House Range.
