This is an old collection piece Pleurocystites cystoid fossil from Ontario Canada. Incredible geometric detail on this one.

The specimen measures about 2 inches

Rock measures 3.25 inches

Note: colors of photos are NOT edited in any way except for brightness, but I take pictures either outside in natural sunlight or in a light box, so colors may seem brighter or different from actuality.

Note: The fossils are packed with extreme care, but if the fossil does break in transit somehow, I can only give any form of compensation if there is video proof of the full unboxing provided that shows the fossil was damaged right out of the box. Thank you.
