<p>Beneath what is now a Lowe’s parking lot just off Route 55 in Mantua Township, New Jersey, lies a remarkable fossil site, soon to be the Edelman Fossil Park &amp; Museum. The site sits atop a layer of sediment known as the extinction layer, marking the boundary between the Cretaceous and Paleogene periods some 66 million years ago. This layer is evidence of the asteroid impact that ended the age of dinosaurs. Geologists and palaeontologists have uncovered more than 1,00,000 fossils to date, representing over 100 species, including marine reptiles, fish, turtles, and sharks. The quarry beneath the future museum provides a preserved ecosystem capturing the final moments of Cretaceous marine life.</p><h3>The Mosasaur and Ancient Seas</h3><p>Among the most striking finds are mosasaur bones, large marine predators that once ruled the shallow seas covering what is now southern New Jersey. These creatures could reach lengths of up to 50 feet, and their remains give scientists insight into marine biodiversity just before the end-Cretaceous mass extinction. The sediments around the fossils show that this region was submerged under the Atlantic Seaway, a warm shallow sea teeming with life.
