Pseudocidaris mammosaComing from the La Rochelle, France area, with but a few recovered each year, Pseudocidaris mammosa with its numerous bulbous spines possibly ranks as the most impressive echinoid fossil that can be purchased. The fossil has been painstakingly cleaned and reassembled by experts rendering the fossil in lifelike three-dimensional slendor with minute details present. Note in the picture that two spines are detached such that the animal can be viewed; you could re-glue these back on if you prefer.
