A tooth from the Ice Age: Mastodon fossil found in San Francisco Bay Area
A 23cm long fossilised tooth discovered in a California creek is offering scientists a glimpse into the Bay Area's prehistoric past.
A prehistoric tooth of a Pacific mastodon has been discovered in a creek near San Francisco, offering scientists a glimpse into the Ice Age. The fossil was identified by geomorphologist Brigid Lynch while conducting a habitat restoration project. At first, Lynch and her colleagues were uncertain about their find, but a reverse image search confirmed it was a Pacific mastodon molar.
Remarkably well-preserved, the tooth includes both its crown and root. Scientists at Stanford University, who now possess the specimen, were surprised by its discovery in San Mateo County. The tooth could contribute to future research as technology advances and new questions arise. This find underscores the importance of protected natural areas in preserving historical evidence.
