    Episode 142 - Phytosaurs

    Episode 142 - Phytosaurs

    Take a walk along the waterways of the Late Triassic, and you could easily think it was a world full of crocodiles! But in fact, those are not crocs, but phytosaurs, a group of predatory reptiles that represent not only one of the oldest groups of carnivorous reptiles to achieve a near-global distribution, but also one of evolution's most famous cases of convergent evolution. So, what features did phytosaurs share with crocs? Where did they differ? And just how croc-like were their lifestyles? Listen in and find out!

    In the news: dinosaur belly buttons, tiny frogs, snake venom, and giant dwarf crocs.

    Episode 141 - Supercontinents

    Episode 141 - Supercontinents

    Perhaps you’ve heard of Pangaea, the supercontinent that existed when our modern continents were puzzle-pieced together. But have you heard of Rodinia? Or Columbia? Scientists have only come to realize in the last few decades that supercontinents are a recurring feature of our planet. This episode, we discuss what counts as a supercontinent, what evidence they leave behind, and the various ways they impact just about every other feature of our planet as they continuously come together and break apart.

    In the news: croc resilience, American cheetahs, dome-headed giraffoids, and traveling termites.

    Episode 140 - Horns and Antlers

    Episode 140 - Horns and Antlers

    Who doesn’t like a flashy bit of headgear? A wide variety of cranial ornamentation is found on a wide variety of animals: sharp horns, branching antlers, bumpy knobs, and more. In this episode, we break down what technically counts as a “horn” (you’ll be unsurprised to learn there isn’t a simple answer!), the vast diversity of animal headgear today and in the fossil record, and the various ways animals have found to use these remarkable structures.

    In the news: sabertoothed faces, head origins, dinosaur climates, and ancient false gharials.

Evil Scok Monkey ,

Informative, Entertaining, and Engaging

Hosts David and Will display real enthusiasm for their subject matter- even the non-reptilian topics!

Good research, clear descriptions and explanations, and nerd humor abound in every episode.

The huge back catalog will keep you captivated for hours if not days.

Dabilge ,

So many great topics

This is my favorite podcast by far. This got me through traveling between clinical rotations (it just happened to line up perfectly with our two-week block schedules) and there's always such an amazing variety of topics, but every topic is well-researched and presented.

They also did a pathology episode that I (among others) requested which was super neat!!

PodcastPope ,

10/10 Listen if you’re patient.

What a show. The time seems long but the whole show of an easy, pleasant, educational listen week after week. The news segments give variety to each episode and each week’s topic has enough scope to engage every listener. My current binge, love these guys.
