How old are shells that wash up on the beach?
How old are shells that wash up on the beach? Mollusk shells found on typical east coast (US) beaches can range from days old (the animal that made the shell died recently) to thousands of years old. Some shells in our state, North Carolina, have been dated as 40,000 years old.
Is it OK to take empty shells from the beach?
For example, some experts say the removal of shells can impact shoreline erosion patterns. This could have dire effects on coastal populations, especially in combination with global warming and rising sea levels. Not only that, but every shell performs some ecological role.
