In this episode of pplpod, we explore the extraordinary life of Mary Anning, the self -taught fossil hunter who helped revolutionize paleontology from the dangerous cliffs of Lyme Regis in early 19th century England. Born into poverty and largely excluded from formal scientific institutions because she was both working class and a woman, Anning spent her life excavating prehistoric creatures that forced scientists to confront the reality of extinction and the immense age of Earth itself. Her discoveries of marine reptiles like the ichthyosaur and plesiosaur completely transformed humanity’s understanding of prehistoric life and helped lay the foundation for modern paleontology.

The episode examines how Anning risked her life hunting fossils along unstable coastal cliffs, taught herself anatomy and geology through relentless self -study, and repeatedly outperformed elite scientists who often failed to credit her work publicly. Along the way, we explore the famous plesiosaur controversy involving French anatomist Georges Cuvier, her groundbreaking discoveries involving fossilized feces and ancient ink sacs, and the broader class and gender barriers that shaped scientific recognition during the 1800s. Ultimately, Mary Anning’s story is about curiosity, resilience, scientific discovery, and the overlooked people who quietly reshape humanity’s understanding of the world.

Key topics covered:

• Mary Anning’s childhood and fossil hunting on the Jurassic Coast
• The discovery of the ichthyosaur and plesiosaur
• Extinction, deep time, and challenges to religious belief
