Love Fruit? Thank (Dinosaur) Mass Extinction
Mar 14, 2025
Chris Doughty, an ecologist from Northern Arizona University, dives into the remarkable world after the dinosaurs. He discusses how their extinction triggered a fruit explosion, paving the way for modern ecosystems. Doughty explores the connection between the demise of these giants and the evolution of larger seeds and fruit-bearing plants. He also draws parallels between dinosaurs and today’s ecological influencers, urging reflection on our role in current extinction trends and their impacts on biodiversity.

The Role of Sauropods as Ecosystem Engineers
Sauropods, the largest terrestrial animals in history, significantly influenced their ecosystems by acting as ecosystem engineers. Their enormous size allowed them to knock down trees, distribute nutrients, and move seeds across vast distances, all of which were critical for maintaining the health of their environment. This behavior, particularly through their waste, played a vital role in nutrient cycling and plant growth. By altering their surroundings, sauropods contributed to a dynamic ecosystem where diverse plant species could thrive, illustrating how large animals shape their habitats in unique ways.
