SquaMates Ep. 33: Chameleon Day Bonanza!

Happy World Lizard Day! Today we talk about the biggest lizards that ever roamed the Earth: mosasaurs! These giant aquatic lizards are often forgotten when we talk about shape diversity in squamates, but they were some of the most specialised and remarkable lizards ever. We dive into their diversity, history, origins, and extinction in this special episode. We also talk about the incredible Mirasaurus, the weird new reptile with bizarre integument structures that recently made the cover of Nature with an illustration by co-host Gabriel!
