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 ...

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.

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 ...

HOLLYWOOD, Fla. – A 10-to-12-foot mako shark, one of the fastest fish in the world, was spotted in North Lake in Hollywood, surprising residents and raising concerns about its health.

That means that if we can prevent further erosion of this genetic diversity in shortfin mako sharks by urgently curbing overfishing, we have more hope for this species to retain the resilience ...

Get Instant Summarized Text (Gist) Shortfin mako sharks, despite being endangered due to overfishing, maintain relatively high genetic diversity, crucial for adaptation and survival. Genomic ...

Wrong turn on the turnpike? It appears to have been the case for a mako shark in Florida recently. The 10-12 foot sea creature was discovered in brackish North Lake in Hollywood, Fla., earlier ...

The situation for shortfin mako sharks in the Atlantic Ocean is particularly dire. Populations are currently managed as two assumed separate populations (or stocks), with fishery-based assessments ...
