Scientists discovered fossilized teeth from seven different shark species in Egypt's Western Desert, revealing a thriving ocean ecosystem that existed millions of years ago. Three of the species had never been documented in this region before.
The Perot Museum in Dallas is celebrating Shark Week with hands-on activities and a major milestone: their curator is starring in Discovery's new show about prehistoric sharks that once swam through Texas. Visitors can explore 270-million-year-old fossils while learning how ancient sharks survived in what's now the Lone Star State.
An international team of 60 aquariums across 15 countries just pulled off something never done before: rewilding sharks. Eighty-two zebra shark pups, raised in captivity and released into Indonesian waters, are now thriving in the wild.
Researchers discovered fossilized teeth from seven shark species in Egypt's Western Desert, proving a thriving ocean covered the region 100 million years ago. Some species had never been found in Africa before.
Emily Morrison went from being terrified of sharks after watching Jaws at age eight to becoming a shark biologist with a Guinness World Record for 106 shark tattoos. Her father's simple library challenge transformed her fear into a lifelong passion that now helps others discover the truth about these misunderstood creatures.
Paleontologists have uncovered fossils of a massive marine predator that ruled the oceans over 80 million years ago, dwarfing today's great white sharks. The discovery sheds new light on prehistoric ocean ecosystems and the giants that once dominated them.
In waters where leopard sharks had nearly vanished, a Thai conservation project is releasing captive-bred shark pups into the ocean after training them with dedicated "shark nannies." The effort is part of a global movement to save shark species from extinction.
Galapagos sharks off Mexico have discovered an ingenious way to deal with pesky parasites: rubbing against manta rays like living scratching posts. Scientists caught this surprisingly gentle behavior on camera, revealing sharks are more resourceful than we ever imagined.

Six years of research in Fiji reveals that bull sharks, known as aggressive predators, actually choose their friends and avoid certain individuals much like humans do. The discovery adds to growing evidence that sharks have complex social lives worth protecting.
Scientists aboard fishing boats in Greece's Amvrakikos Gulf are saving sharks and rays caught accidentally, discovering the region is a crucial nursery for threatened species. Over 95% of carefully handled sharks survive when released back to the sea.
Scientists watching 184 bull sharks over six years discovered something surprising: these ocean predators actively choose friends, swim together, and even avoid certain individuals. The findings challenge everything we thought we knew about shark social lives.
A 550-million-year-old sea sponge fossil just explained why the earliest animals seemed to vanish from history. The discovery reveals that ancient sponges were too soft to fossilize, solving a puzzle that has stumped scientists for decades.
A four-meter sleeper shark was captured on camera nearly 500 meters deep in Antarctic waters, the first confirmed shark sighting this far south. The discovery reveals these mysterious creatures may have thrived undetected in Earth's coldest ocean for ages.
A single fossilized ammonite, discovered by teenage David Attenborough in the English countryside, ignited a passion that would inspire decades of groundbreaking nature documentaries. Now at 99, he still treasures the thrill of those childhood fossil hunts.
Construction workers accidentally discovered dinosaur fossils at Dinosaur National Monument last September, marking the first fossil excavation at that location since 1924. Scientists believe the 3,000 pounds of fossils belong to Diplodocus, an 80-foot-long giant that once roamed Colorado in herds.
Scientists discovered fossils of six modern fish groups in Egypt, filling a mysterious 10-million-year gap in the fossil record after the asteroid that killed the dinosaurs. The find shows how today's ocean fish rapidly evolved after one of Earth's biggest disasters.
Scientists found DNA from five shark and ray species, including the gentle basking shark, thriving in waters around Dutch offshore wind farms where bottom trawling is banned. Clean energy towers are accidentally creating ocean refuges where fish can finally recover.
Scientists discovered over 100 fossils in northwestern Canada that show complex animals evolved up to 10 million years earlier than we thought. The find reveals creatures could move and hunt millions of years before similar fossils found anywhere else.
Workers paving a parking lot in Colorado accidentally discovered the first new dinosaur fossils at Dinosaur National Monument in over a century. The 3,000-pound haul likely belongs to a Diplodocus and is now being studied alongside fossils dating back 150 million years.
