11" Pennsylvanian Arthropod (Paleohelcura) Trackway Plate - Oklahoma

Paleohelcura are the fossilized trackways of arthropods, in this case it was likely a scorpion-like arthropod responsible for the impressions. The divots that run diagonally to the midline of the track are created by the long, club-like walking arms of the arthropod. This Paleohelcura is preserved on a thin slab of sandstone, and was collected from the Keota Sandstone in Oklahoma and would be Pennsylvanian in age, or approximately 307 million years old.

There are multiple trackways visible on the mudstone with the longest one being about 11" long.

It comes with an acrylic display stand.
