This is WT967; the extinct sand dollar Dendraster ashleyi (Arnold, 1907) or Dendraster gibbsii (Rémond, 1863). Discovered in May 2024 embedded in its 5 million year old sandy seafloor tomb, now turned to stone on a Santa Cruz beach, this specimen has been prepared and is on on its way to the Department of Invertebrate Geology at the California Academy of Sciences in San Francisco as a small component of our scientific research into the paleontology and evolution of life in the ancient Monterey Bay. We are additionally examining the Pliocene current-protected sediments from under these ancient sand dollars for microscopic fossilized plankton called foraminifera to help us refine the age and environments that these faunas represent. Very exciting ongoing research happening here at Pacific Paleontology Labs.
