Sharktooth Hill stands out for fossil hunting due to its Miocene bonebed in the Round Mountain Silt, holding one of the world's densest marine fossil concentrations with hundreds of specimens per cubic yard. This 15-million-year-old site from the Temblor Sea yields shark teeth, whale bones, and 140 vertebrate species, far surpassing typical fossil locales. Its accessibility through guided quarries makes professional-grade paleontology open to all levels.
Prime spots include Ernst Quarries for paid digs unearthing shark teeth every 5-10 minutes, Buena Vista Museum excursions into protected bonebeds, and surface hunts around trails. Activities range from sifting sediment for Megalodon relatives to spotting whale jaws and turtle shells. Nearby museums display quarry specimens for context.
Hunt in March-May or September-November for mild 70-80°F weather; summers scorch above 100°F with low humidity. Expect dusty, physical labor in remote foothills, so prepare for dirt and sun. Quarries provide tools, but bring hydration and protection.
Local ranchers first spotted shark teeth here in the 1850s, sparking a paleontology rush that continues with enthusiast communities. Guided tours blend scientific history with hands-on discovery, fostering respect for the site's protected status. Collectors prize the enamel's durability, connecting modern hunters to ancient seas.
Book digs at Ernst Quarries or Buena Vista Museum in advance, especially weekends, as spots fill fast for premium sessions around USD 70. Time visits for spring or fall to dodge Central Valley summer highs over 100°F. Check quarry hours, typically 8 AM starts, and confirm access rules since much of the hill is protected.
Wear old clothes and closed-toe shoes for dusty, muddy digs that leave you filthy. Bring water, sunscreen, and snacks, as facilities are basic. Keep finds under personal use limits and declare large collections when leaving.
