Ken Lacovara, a paleontologist and founder of a new museum in New Jersey, takes listeners on a fascinating journey through the world of dinosaurs. He reveals insights about the asteroid impact that led to extinction and emphasizes the critical role of fossil sites in New Jersey. The excitement of uncovering fossils, like a femur with shark bite marks, paints a picture of prehistoric life. Lacovara also discusses the importance of public engagement in preserving history and inspiring future generations to connect with our planet's deep past.

The Discovery of Fossils at Edelman Fossil Park
The Edelman Fossil Park in New Jersey has become a significant site for paleontological research, revealing a wealth of fossils that date back 66 million years. Paleontologist Ken Lacovara initially underestimated the site in 2003 but discovered its importance after ongoing excavations revealed a dense concentration of fossils from the end of the dinosaur era. Notably, more than 100,000 fossils from various species, including clams, turtles, and sharks, have been unearthed, indicating a vibrant ecosystem prior to the catastrophic asteroid impact. This quarry offers a unique glimpse into a pivotal moment in Earth's history, as it preserves a distinct extinction layer that showcases life just before and after the asteroid hit.
The Impact of the Asteroid
The asteroid impact that occurred 66 million years ago played a crucial role in the extinction of the dinosaurs. Lacovara details the sequence of events that unfolded after the asteroid struck, including a massive earthquake and extreme temperature fluctuations that led to the rapid demise of terrestrial life. The aftermath included a powerful tsunami that likely swept the remains of these creatures into the ocean, creating what is now known as a bone bed. This site is exceptional, as it contains a complete ecological snapshot from the moment of extinction, allowing scientists to study the conditions that contributed to one of the greatest mass extinctions in history.
Public Engagement in Paleontology
A key objective of the Edelman Fossil Park is to engage the public in hands-on paleontology, allowing visitors to participate in fossil digs. The park has seen immense interest from the community, evidenced by a past open house that attracted thousands eager to hunt for fossils. This initiative not only educates visitors about geology and paleontology but also fosters a deeper appreciation for the Earth’s history. By providing a space where people can connect with ancient life, the park aims to inspire future generations about the importance of preserving our planet and understanding its geological story.
Connecting Dinosaurs to Modern Environmental Issues
Lacovara emphasizes the relevance of studying dinosaurs and understanding deep time in addressing contemporary environmental challenges. He draws parallels between the past mass extinctions and the current biodiversity crisis driven by human activity. By contextualizing the dinosaurs’ story within Earth’s history, visitors are encouraged to reflect on their role in the environment and the impact of climate change. The goal is to instill a sense of responsibility for protecting the planet, highlighting that, unlike the dinosaurs, humans have the agency to affect positive change for future generations.
What happened in the days, even hours, after an asteroid set off the fifth extinction? A New Jersey quarry, and site of a new museum founded by paleontologist Ken Lacovara, sheds light on the mystery.
Correction: An earlier version of this story incorrectly stated that Mantua Township, NJ helped to raise money for the construction of the Edelman Fossil Park & Museum. Paleontologist Ken Lacovara partnered with Rowan University to fundraise.
