Hey everyone! Nathan wanted to know how poisons work and we're starting with some metals! Metal poisons are pretty interesting because they aren't complex molecules or anything, they're like single atoms running around messing up your biological systems! But how do metals interact with biology in the first place? Let's get into it!

*Hey folks, some people are having a tough time hearing the episode on some platforms, this reupload is an attempt to see if we can fix that*

At Nathan's insistence, this is the last Mesozoic episode for now! We talk about dinosaurs, across the Jurassic and Cretaceous periods, including heavy-hitters like T Rex! We also dispel some misunderstandings about velociraptor and other fun dino facts!

Yessss we're finally doing it! Dinosaurs! But only Jurassic ones! Yeah, that's right, a bunch of dinosaurs were only around in the Cretaceous, like velociraptor and T. rex. But don't worry, I'm sure some of your favs were in the Jurassic, like good ol' stegosaurus! What is a dinosaur? Who was around in the Jurassic? Find out this week on Petri Dish!

Yay! The Age of the Dinosaurs! In this episode, we lay the groundwork for finally digging into dinosaurs in part 2 -- we discuss the changes to the climate and continents of the Jurassic and how that played into the development of the dinosaurs.

We end our discussion of the Triassic period with the land and air -- this is the time when dinosaurs and pterosaurs first evolved, along with the first mammals!

We're taking a one episode break, Nathan kind of explains why...

In our last episode, we discussed The Great Dying, the transitional extinction event that ended the Permian and Paleozoic times and kickstarted the Triassic and Mesozoic! While the Mesozoic is often thought of as the Age of the Dinosaurs (and it *is* the time when they both evolved and went largely extinct), the first part of the Mesozoic was dominated by other groups of animals. But who?! Find out, this week on Petri Dish!

Hey, times are tough! So in a bit of escapism, Petri Dish has decided to dive into one of the largest extinction events of all time -- the Great Dying! Serving as the end of the paleozoic and start of the mesozoic, the Great Dying killed of around 90% of marine animal species and 75% of land species, clearing things out a little bit for the start of the age of the Dinosaurs!
