Our study was one of the first to date Florida coastal deposits using fossil shark teeth and a technique that looks at variations in ocean strontium. Strontium is a chemical element that occurs ...

Remarkably, fossil shark teeth are also incredibly abundant. Sharks ruled the earth's oceans for 400 million years, and every individual grows and sheds thousands of teeth in their lifetime.

The ratios of strontium isotopes in fossil shark teeth can be used to better understand how coastal environments evolved in ancient times, according to our newly published work. Our study was one ...
