Dinosaur-era shark with 300 teeth caught alive near Portugal
Researchers from Portugal's Institute for the Sea and Atmosphere have caught an alive dinosaur-era shark, named frilled shark, with 300 teeth neatly lined in 25 rows. The species, dated back to around 80 million years ago, usually lies 390-4,200 feet below the surface. The 1.5-meter-long shark adds to the very few specimens found recently in Australia, New Zealand, and Japan.
