Very Distinct Middle Cambrian Ctenocystoid
Stock Number  XIOE34

Name:   Ctenocystis utahensis
Age:  Middle Cambrian
Formation:  Wheeler Shale
Location:  Millard County, Utah
Size:  Plate is 1.7 inches tall
Price:  SOLD

This is a fine example of a rare echinoderm. It is a beautiful Ctenocystis utahensis from the Wheeler Shale of Utah. These unique animals are the oldest known echinoderms in the subphylum Homalozoa. The book, ''Some Middle Cambrian Fossils of Utah'', describes these ctenocystoids - ''These tiny, free-living animals are known only from the Spence Shale of Utah.'' Well, this plate was found in the Wheeler Shale! The ctenocystoid is easily seen and is very detailed. The distinct structure of this echinoderm looks like the photo from the book mentioned above (see photo #2). This is a very collectible early echinoderm from the Wheeler Shale.

A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
