The story behind Dr. Gerta Keller's world-shattering scientific discovery that dinosaur extinction was NOT caused by asteroid impact, but rather by volcanic eruptions on the Indian peninsula, a discovery that highlights today's existential threat of greenhouse gasses and climate change and one that sparked an all-out war waged by the scientific establishment.Part scientific detective story, part personal odyssey, The Last Extinction is the definitive account of a radical theory that has reshaped how we understand our planet's past and, as we face the possibility of a sixth extinction, how we might survive its future.For decades, the dominant theory held that an asteroid impact caused the dinosaurs' extinction. But Princeton Geologist Dr. Gerta Keller followed the evidence to the truth: Deccan volcanism, a series of massive volcanic eruptions in India, triggered a long-term climate catastrophe and Earth's fifth mass extinction. Her findings upended the field and ignited a bitter feud in modern science—what became known as the “Dinosaur Wars.”Raised in poverty on a Swiss farm and told she could never be a scientist, Keller defied expectations, earning her PhD at Stanford and battling her way into the highest ranks of Geology, eventually becoming a Professor of Paleontology and Geology at Princeton University. Her refusal to back down in the face of ridicule, sabotage, and sexism makes her story as thrilling as her science, which offers urgent insight into today's climate crisis: Sustained planetary upheaval—not a single cataclysmic event—can plunge the planet into an age of death.She is the author of "The Last Extinction: The Real Science Behind the Death of the Dinosaurs."https://www.amazon.com/Last-Extinction-Science-Behind-Dinosaurs/dp/B0DZ13NHZV http://www.yourlotandparcel.org

For decades, we've been told the dinosaurs were wiped out by a single catastrophic asteroid impact — a story that has become almost mythic in its simplicity. But what if that isn't the full truth? In this episode, host Matt Crawford speaks with Professor Gerta Keller, one of the world's leading paleontologists and a bold voice challenging conventional science. Drawing on over 40 years of fieldwork and groundbreaking research, Keller's new book The Last Extinction: The Real Science Behind the Death of the Dinosaurs reexamines the evidence and makes a compelling case that massive volcanic eruptions — not just an asteroid — drove the greatest extinction in history. Together, they discuss scientific resistance, the importance of questioning accepted narratives, and what ancient mass extinctions can teach us about our own fragile planet today.

The Space Show with Dr. Gerta Keller for Sunday, Sept. 14, 2025 are ready!This Space Show program featured guest Dr. Gerta Keller, a paleontologist and geologist from Princeton, who has challenged the traditional asteroid impact theory for dinosaurs' extinction, presenting evidence that volcanic activity from the Deccan Traps in India was the primary cause. Our discussion concluded with an exploration of the scientific debates surrounding dinosaur extinction theories, including the role of climate change and the implications for understanding current environmental challenges.Dr. Keller, a professor emeritus of paleontology and geology at Princeton, shared her journey from a childhood in poverty to becoming a leading expert on mass extinctions and impact events. She discussed her unconventional path, including traveling the world during wars and surviving a shooting, before eventually pursuing a career in science. Dr. Keller's research challenges the traditional asteroid impact theory for the extinction of dinosaurs, proposing instead that volcanic activity played a significant role. The Space Show audience was introduced to her work and invited to learn more about her findings and career.In more detail, Dr. Keller shared her remarkable journey from a young girl loving to read in Switzerland to becoming a pioneering paleontologist and geologist. She described her early life, education, and travels, including her experiences during the Flower Child era in San Francisco. Gerta's academic career took her from SF City College to Stanford and Princeton, where she worked on microfossils and climate change. She eventually returned to her interest in dinosaurs and challenged the widely accepted theory that an asteroid impact caused the dinosaurs' extinction. Gerta's research suggested that volcanic activity and climate change played a significant role in the fifth mass extinction, challenging the Alvarez hypothesis.Dr. Keller discussed her discovery of impact glass spherules from multiple asteroid impacts during the Eocene, approximately 38 million years ago, which contradicted the widely accepted theory that a single asteroid impact caused the Cretaceous-Paleogene extinction event 66 million years ago. She explained that her research, which included finding pristine 2-meter thick layers of impact glass in Mexico, was initially rejected by peer reviewers for 10 years before being published in 1983. The discovery led to a heated debate at a major conference in Nice, France, where Keller presented evidence of multiple impacts, while others argued for a tsunami theory.Gerta discussed her research challenging the asteroid impact theory for the KT boundary event, presenting evidence that the iridium anomaly could instead be explained by volcanic activity. She described how her work with a NASA Astro chemist and their student revealed that the iridium was actually from water-suspended material, not an asteroid impact. Gerta also shared her findings from extensive drilling in India, where she discovered that massive Deccan Traps volcanic activity occurred rapidly and had a significant global climate impact, supporting his theory that volcanic activity rather than an asteroid caused the mass extinction.Dr. Keller explained that the Deccan Traps volcanic activity, not the Chicxulub impact, caused the dinosaurs' extinction. She described how the volcanic eruptions led to gradual global warming over millions of years, which eventually caused the extinction by making dinosaur eggs unviable due to thickened shells. She emphasized that her theory has been competing with the impact theory for decades, but recent evidence supports her volcanic hypothesis. She noted that while the Chicxulub impact occurred 200,000 years before the mass extinction, it was not the cause.Keller discussed the Cretaceous-Paleogene (KP) extinction event, emphasizing that while the Chicxulub impact occurred, it did not cause global effects. She explained that the Deccan Traps volcanic eruptions were the primary cause of the mass extinction, as they released vast amounts of toxins into the atmosphere, blocking sunlight and preventing new life from emerging. Keller noted that dinosaur specialists rejected the Alvarez theory soon after its publication, as they had data showing the extinction was not global. She also clarified that while crocodiles and alligators survived the extinction, their eggs were not affected by the volcanic toxins, unlike those of dinosaurs.Our discussion then focused on the factors that contributed to the extinction of dinosaurs, with Keller explaining that while the asteroid impact is often highlighted, volcanic activity from the Deccan traps in India played a significant role over millions of years. David, using ChatGPT, shared insights about crocodiles' evolutionary advantages, including their cold-blooded nature, diverse diet, and aquatic lifestyle, which allowed them to survive mass extinction events better than larger land animals. The conversation concluded with Gerta describing the "Dinosaur Wars" period since 1980, where scientific debates over the cause of dinosaur extinction led to funding prioritization for impact theory research over volcanic activity, despite growing evidence supporting both factors.Dr. Gerta Keller, discussed her alternative theory to the asteroid impact hypothesis for the extinction of dinosaurs, emphasizing that her idea has been consistently ignored despite substantial evidence. She highlighted the parallels between the rapid climate change that led to the dinosaurs' extinction and the current human-induced climate crisis, expressing concern about the potential consequences. I noted the lack of competing theories for the dinosaur extinction until Keller's work and asked about the value of her findings for future generations. Ajay, interested in the Deccan volcanic theory, inquired about ongoing research in India, and the discussion concluded with reflections on the moral lessons from the past and the urgency of addressing climate change.Special thanks to our sponsors:Northrup Grumman, American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentOur Toll Free Line for Live Broadcasts: 1-866-687-7223For real time program participation, email Dr. Space at: drspace@thespaceshow.comThe Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

The idea behind this show is pretty simple: A university campus is a destination for all kinds of interesting people, so why not invite some of these folks out to brunch, where we’ll have an informal conversation about their work, and then we’ll turn those brunches into a podcast?It’s a tough job, but somebody has to do it.With apologies to Jack Kerouac, this is the first of two “on the road” episodes we recorded in Brooklyn, New York, while attending On Air Fest 2019. It features two of our favorite podcasters, Elah Feder and Annie Minoff, who co-host and produce Undiscovered, the podcast from WNYC’s iconic radio show Science Friday.Through the hums and hisses of a Brooklyn coffee shop, Elah and Annie talked with host Ted Fox about how they look for stories that haven’t been told, the importance of good communication between the scientific community and the rest of us, and the paleontologist at the center of one of their most memorable episodes—who also might be the one person you’d want at your side in the event of the zombie apocalypse.
