Timestamps are as accurate as they can be but may be slightly off. We encourage you to listen to the full context.
Podcast Summary
In this fascinating conversation, paleontologist Dave Hone takes us deep into the world of dinosaurs, revealing how these incredible creatures dominated Earth for over 160 million years. He explores the evolution, biology, and behavior of iconic predators like T. Rex (07:18), demonstrating how paleontologists use forensic-level detective work to reconstruct ancient ecosystems from bite marks, bone structure, and fossil evidence. From debunking Jurassic Park myths about pack hunting (100:59) to explaining the surprising intelligence levels of these "terrible lizards," Hone showcases how modern techniques are revolutionizing our understanding of dinosaur social lives, hunting strategies, and ultimate extinction—offering profound insights into both Earth's deep history and the future of life itself.

Key Takeaways
Accumulate the Database Before Drawing Conclusions
Resist the temptation to build grand theories on single spectacular specimens. (139:36) One Microraptor eating one fish doesn't prove fish-eating specialization—wait until you've got dozens of specimens with stomach contents before declaring behavioral patterns. Build your data pool systematically before making definitive claims about ancient ecosystems.
Master the Art of Independent Evidence Lines
Stack multiple unrelated data streams that all point to the same conclusion. (138:37) Spinosaurus shows crocodile-like teeth, isotopic signatures matching aquatic animals, plus discovery locations near water systems—when separate evidence sources converge, your interpretation becomes bulletproof. Seek convergent proof from geology, anatomy, and chemistry simultaneously.
Question the "Obvious" With Rigorous Methodology
Challenge popular narratives by demanding extraordinary evidence for extraordinary claims. (110:12) Pack hunting in dinosaurs sounds compelling until you realize leopards can follow the same game trail hours apart, leaving identical "group" trackways. Apply the same skeptical rigor you'd use for living animals to extinct ones—correlation isn't causation, even across millions of years.
Scale Your Perspective to Deep Time Success
Think in terms of evolutionary advantages over 100+ million year timescales rather than immediate optimization. (84:06) Tyrannosaurs dominated Earth for longer than mammals have existed—their "inefficient" small arms and power-walking gait clearly worked at planetary scale. Judge success by geological longevity, not human intuitions about perfect design.
Extract Maximum Value From Limited Signals
Develop forensic-level skills to reconstruct entire ecosystems from fragmentary evidence. (38:10) Bite marks sitting on top of erosion damage reveals scavenging behavior; circular punctures plus parallel scratches indicates both bone-crushing and meat-stripping feeding strategies. Train yourself to see complete stories in partial data—every mark tells part of a larger behavioral narrative.
