Have you ever wondered how we figure out when things happened way in the past? When a scientist says "it's 100 million years old..." just how did they figure it out? Today I'm talking to Dr. Matthew Jones. He's a paleontologist at Arizona State University and his specialty is fossil mammals (though he admits he was a dinosaur kid). It's often his job to figure out just how old is this rock and he's going to tell us about the science of dating ancient things. Stratigraphy, radioactive clocks, iridium rain and a commit that slammed into the earth. Who knew dating was so risky.

We will also talk about three famous trophic cascades, where the removal or introduction of a species has consequences that rebound across the entire system.

It's a field that combines mathematical modeling, ecology, evolution, medicine, veterinary science... and he actually got into this as a cultural anthropologist interested in social justice. How do you get from social justice to the fate of vampire bats in a fragmented ecosystem? tune in to find out in this episode of the BioAudio podcast where we explore community disease ecology in wild populations.
