Kevin Sievers has been coming to the Academy of Natural Sciences of Drexel University since he was a little kid to learn about the ancient animal history on display. Now, as a Drexel student, he gets to work there.

In the Arctic, a team that included scientists from the Academy of Natural Sciences of Drexel University found fossils of a giant new species of extinct armored fish that they named Bothriolepis rex — the new king of Bothriolepis.

The discovery of a group of young, prehistoric fish fossils provides some insights into the extinct creatures’ lives — and how fish today might be similar to them.

A unique fossil in the Academy of Natural Science of Drexel University’s collection continues to fuel important paleontological discoveries more than a century after it came into to the museum.

Eighteenth-century land surveyor William Smith was a rock star. And we mean that quite literally — Smith’s 1815 map of England, Wales and part of Scotland was the world’s first look at the organization of the earth beneath our feet. Less than 200 copies of this seminal work exist today and the Academy of Natural Sciences of Drexel University owns one of them.

When he’s not helping discover new dinosaurs and fossils, the Academy of Natural Science’s Jason Poole uses the prehistoric beasts as inspiration for his art.

More than a thousand residents and visitors to southern New Jersey will dig their own fossils and learn from the Drexel University paleontologist and students who conduct globally significant scientific research at Mantua Township's third annual Community Fossil Dig Day.

A Drexel-led team has described a new dinosaur species with the most complete skeleton ever found of one of the largest animals to ever walk the Earth. At 85 feet (26 m) long and weighing about 65 tons (59,300 kg) in life, Dreadnoughtus schrani is the largest land animal for which a body mass can be accurately calculated.

To the surprise of paleontologists from the Academy of Natural Sciences of Drexel University and the New Jersey State Museum, two halves of a turtle bone, discovered 162 years apart, fit together perfectly. The discovery provides new insight into one of the largest turtle species that ever lived.

The discovery of new fossil materials from the ancient fish species Tiktaalik roseae has revealed a key link in the evolution of hind limbs. The newly described, well-preserved pelves and partial pelvic fin from this 375 million-year-old transitional species between fish and the first legged animals, reveals that the evolution of hind legs actually began as enhanced hind fins, contrary to the existing theory that large hind legs developed after vertebrates transitioned to land.

Roaring, thrashing, life-size dinosaurs and the awe-inspiring stories of prehistoric earth are unfolding at the as Dinosaurs Unearthed makes its East Coast debut at the Academy of Natural Sciences.

For Ken Lacovara, an associate professor in the College of Arts & Science’s Biodiversity, Earth & Environmental Science (BEES) department, a typical day of studying prehistoric fossils might begin when he eats eggs from the dinosaurs roaming his backyard.
