Vaquerosella coreyi (Durham, 1955)

Branch Canyon Formation
Santa Barbara county, California, USA

Middle Miocene Period (16-11 Million Years Old)

Sand Dollar : 3.60 in. longest diameter

1 inch = 2.54 cm

A rare echinoderm species. Perfect for study and display in your collection. One near complete Vaquerosella is on the original sandstone matrix.

An uncommon echinoderm, the Vaquerosella is bilateral, when most echinoderms mature beyond this stage in infancy and form their typical 5 sided features. In the Upper to Middle Miocene of California these sand dollars are of only a few known species that show these characteristics. Research is still ongoing on these elusive echinoderms and the most recent focus has been towards how the animal fed.
Description

Details

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.
