Discovered along California's central coast, these fossil sand dollars represent a genus of echinoderm that no longer exist in modern times. This specific genus, the Vaquerosella, was abundant in patches off shore the Middle Miocene coastline of a region that would have stretched from roughly south of San Francisco, California then south to north of Baja, Mexico. Living along what must have been thousands of oysters, barnacles, and scallops, these tropical seas were also home to many fish and shark species, evident by the other fossils discovered at this site.
These fossil sand dollars are found in a section of the Branch Canyon Formation in Santa Barbara county in a region known for marine fossils.
Each of these specimens were collected and prepared by hand, by us at AETC.
