This is a very rare fossil association. It is a Trilobite and Ctenocystis utahensis plate from the Wheeler Shale of Utah. Ctenocystoids 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 and trilobite are easily seen and are very detailed. The distinct structure of this echinoderm looks like the photo from the book mentioned above (see photo #2). This is a very unique fossil association from the Wheeler Shale.

This fossil was collected and obtained legally, and is also being sold legally.
