Sharktooth Hill (Round Mountain Silt)
Bakersfield's legendary Middle Miocene 'bonebed' — a single thin layer of the Round Mountain Silt that has produced more shark teeth, marine mammals, and reptile remains per square meter than almost any other site on Earth. The classic locality is the Ernst Quarries (already in our atlas as a separate dossier); this entry covers the broader formation.
All productive ground is private — Buena Vista Museum (Bakersfield) and the Ernst family operate the only public-facing dig programs. Scientific work is conducted under California fossil heritage rules with permit.
Permit-only via Ernst Quarries day digs (book through Buena Vista Museum) or sponsored academic field trips. The bonebed itself is on private ranch property.
California Vertebrate Paleontology resources are protected; private-land collecting requires landowner agreement. Scientifically significant specimens are flagged for institutional curation.
- Extreme summer heat (110°F+)
- Rattlesnakes
- Steep dig-site slopes
- Book Ernst Quarries digs early — spring/fall slots fill 6-12 months ahead
- Bring a brimmed hat, electrolytes, and gloves; the silt is abrasive
- The Buena Vista Museum's Sharktooth Hill exhibits are essential context before/after a dig
