11.3" Cruziana (Fossil Trilobite Trackway) Plate - Oklahoma

Cruziana are the fossilized trackways of arthropods, in this case likely a trilobite.
The widest part of the trilobites shell leaves the parallel outer furrows and the leg movements create the diagonal marks in the center of the track. This Cruziana is preserved on thin slab of mudstone, and was collected from the Desmoinesian Formation in Oklahoma and would be Pennsylvanian in age or approximately 305 million years old.

There are multiple trackways visible on the mudstone with the longest one being about 4 1/2" long.

It comes with an acrylic display stand.
