As part of Science Friday’s 33rd anniversary show, we’re revisiting our listeners’ favorite stories, including this one from 2022.

66 million years ago, a massive asteroid hit what we know today as the Yucatán Peninsula of Mexico. Many people have a general idea of what happened next: The age of the dinosaurs was brought to a close, making room for mammals like us to thrive.

But fewer people know what happened in the days, weeks, and years after impact. Increased research on fossils and geological remains from this time period have helped scientists paint a picture of this era. For large, non-avian dinosaurs like Triceratops and Tyrannosaurus rex, extinction was swift following the asteroid impact. But for creatures that were able to stay underwater and underground, their post-impact stories are more complicated.

In 2022, Utah-based science writer Riley Black joined Ira to discuss her book The Last Days of the Dinosaurs.

Transcripts for each segment will be available after the show airs on sciencefriday.com.
