The last paper from my postdoc with @ChristianSidor (and the 40th of my career!) is out today in @JVP_vertpaleo where we describe a slew/mess of small Antarctic #temnospondyls from the lower+middle Fremouw Fm (Early Triassic) 📰: doi.org/10.1080/027246… #temnovember 🧵👇 (1/6)

@incisoria Thank you very much to @calvincfso @PaleoBadger and all other authors from commissioning me to illustrate this amazing taxon and congratulations on a great paper!

Here is another great thread by @incisoria one of the authors of the paper

I took a needed break from social media last week so I couldn’t comment on this amazing species until now. Here is a great thread about this species

Last week saw the description of a REALLY cool burrowing temnospondyl from Late Triassic North America called Ninumbeehan dookoodukah I was lucky enough to be commissioned to illustrate this amazing species in a triptych showing it in its environment across seasons

#2024SVP @calvincfso: Morphometric analysis indicates body proportions similar to some modern (especially terrestrial) salamanders.

#2024SVP @calvincfso: Recovered as a stem-caecilian when presacral vertebra count was included as a character. Outside of (but closely related to) lissamphibians when this character is excluded.

#2024SVP @calvincfso: New taxon is from Mazon Creek. Has a large number of presacral vertebrae, known from an adult specimen.

#2024SVP @calvincfso: A new slender, long-bodied amphibamiform temnospondyl

I first saw some of these specimens in 2018 when I was visiting UW to look at their metoposaurid bonebed material (CC @AaronKufner) and have been out to the site as well. It's really exciting to see the growing body of small Late Tr temnos in N. America #MoreThanMetoposaurids
