Frequently Asked Questions
How old are fossil cow shark teeth? The age varies depending on the species and geological formation where a specimen was found. Cow shark fossils occur across different parts of the geological record, so the age of an individual tooth should be tied to its documented locality and provenance. Geological context provides a more reliable basis for determining age than the appearance of the tooth alone. For collectors, locality information also adds valuable context by connecting an individual specimen to the ancient marine environment in which the shark lived.
Do cow shark teeth occur in different sizes? Yes. Size varies among species, tooth positions, individuals, and geological specimens. This gives collectors an opportunity to encounter teeth with different proportions and morphological details.
How do fossil cow shark teeth differ from modern shark teeth? Fossil teeth have undergone geological processes that alter their original composition and appearance. Depending on the conditions of fossilization, they may display mineral colors and surface characteristics associated with the surrounding sediment and geological environment.
