We can partially thank a cooling climate for not having to deal with Livyatan and megalodon. But how have we humans dealt with dropping temperatures, even fairly recent ones? Check out our episode, “How To Survive the Little Ice Age” to learn more about a roughly 450 year old village in southwest Alaska that thrived during this time.

Today's new video is about Livyatan melvillei: a sea monster so hungry it might have eaten itself to extinction. (https://youtu.be/NNF6zoWwtgc) While modern sperm whales use suction feeding, what type of feeding technique did Livyatan use?

In this week's episode we talked about the red panda and one of its ancient relatives. Red pandas are NOT related to giant pandas, despite both being named "panda," having false thumbs, and eating bamboo. And if you're thinking, "Bamboo? Aren't bears carnivores?" you're right! So how did the giant panda, a member of the carnivorous Ursidae family, evolve into an herbivore? Despite how it looks, nothing about the history of the giant panda is black and white. Find out more in our episode, “The Fuzzy Origins of the Giant Panda”

A red panda in... East Tennessee? Pristinailurus, a red panda relative also known as Bristol’s Appalachian panda, had similarities to the red pandas we know today – like in its overall build. But it was much larger in size. It’s estimated that Pristinailurus weighed between 8 and 15 kilograms, compared to the average living red panda at 5 kilograms.

We know this because, unlike the otherwise sparse fossil record of the red panda and its relatives found mostly in Eurasia, a fossil site in Gray, Tennessee preserves two nearly complete skeletons. This rich fossil material gives us insight into the evolution of the red panda family, like the fact that both Pristinailurus and its close relative, the modern red panda, probably descended from an older relative shared with the mountain lion-sized Simocyon.

Learn more about the discoveries from the Gray fossil site in our new video! https://youtu.be/knh8skpSQLs
