A routine field survey has led to a significant prehistoric discovery. The finding is a rare and intact tooth from the ice age, estimated to be around 10,000 years old. It belongs to a mastodon, a creature from a bygone era.

The discovery was made during a recent survey, and it is considered stunning due to the tooth's intact condition.

Further details about this discovery can be found through KTVU FOX 2 News, which reported on the finding of the 10,000-year-old mastodon tooth in a Bay Area creek.
