SquaMates Ep. 36: Is this a mosasaur?
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!

Correction
Mark forgot to mention the chameleon genus Nadzikambia! This is a genus that formerly belonged to Chamaeleo and then Bradypodion. There are only two species. They look much like other arboreal chamaeleonine chameleons.

An unexpected crossover is afoot! Hiral and Mark met up with Dr Tom Major and Benjamin M. Marshall of the Herpetological Hightlights Podcast while they were at the 10th World Congress of Herpetology in Kuching, Malaysia. We sat down together and talked about the amazing conference, podcasts, and the herpetological community at large. We had such a great time!

SquaMates Ep. 26: Let’s talk about snakes, baby
In this episode we gently debate subspecies, and then dive into several snake papers, from their anomalously extensive and rapid diversification, to a recent taxonomic change. Regrettably the audio on this episode was affected by a technical error, so it is far less than our usual quality (Ethan and Hiral are a little quiet, sorry!). Hopefully it doesn’t affect the listening experience too badly!

SquaMates Ep. 18: Amici manere domi!
Here’s episode 18, a Works in Froggress episode, featuring the Mates, Dr Mark D. Scherz, Gabriel Ugueto, and Ethan Kocak, talking about what’s going on in their new lives stuck inside—Ethan’s setting off on a freelancing lifestyle, Gabriel has been tweaking the same illustration forever, and Mark is working on FIIIIIIIIIISH! The Mates then dive into a discussion about Uroplatus geckos!

A note: this episode was recorded on the 24th of April 2020, a time when most of humanity seemed united in their fight against a common enemy, the coronavirus COVID-19. In the meantime, another enemy of humanity has been brought into the limelight that, by its very nature, divides. That enemy is racism. The experiences of Christian Cooper highlight how people of colour may be treated when engaging in field sciences like ornithology or herpetology, and similar stories are being heard from people of colour across social media (e.g. see the #BlackInNature tag on twitter). We must strive to make field-based sciences like herpetology inclusive of people of colour, and to fight racism wherever we encounter it in order to disassemble the systematic discrimination that plagues our fields and our societies. We at the SquaMates podcast stand firmly behind the BlackLivesMatter movement.

Episode 16 is here, in this episode we—Dr Mark D. Scherz, Gabriel Ugueto, and Ethan Kocak—feature an interview with Professor Emily Taylor of Cal Poly, and two of her students, Isabelle Barnes and Katie Rock, talking about their amazing dataset about sex biases in publishing in herpetology, recorded at the 9th World Congress of Herpetology in Dunedin, New Zealand.
Episode notes sometimes get clipped on your device or by your podcast provider; for full (extensive) notes (and references), go to http://www.squamatespod.com
For more information about the dataset we talk about, check out Professor Taylor’s tweet about it here, but most importantly, read the detailed blog post about it here. We were thrilled to be able to interview this team, and will update this post when the data are published.
