We now plan to study other taxa from East Kirkton (and nearby) to assess their identity, and see if any confidently be assigned to crown Tetrapoda.

Tetrapoda*: how it started vs. how it's going.
*OK, OK: stem-Tetrapoda. But it's not as snappy.

🦠🇺🇸 GRIPE AVIÁRIA INFECTA PORCO NOS EUA
Pela primeira vez, a gripe aviária H5N1 foi detectada em um porco nos EUA, aumentando o alerta de cientistas. Porcos podem mesclar genes de vírus aviários e humanos, gerando cepas mais perigosas para humanos, disse o Departamento de Agricultura dos EUA.

This is super important, because Westlothiana, as the (formerly) oldest crown tetrapod, had been used for molecular divergence estimates of Tetrapoda, and (mistakenly) for Reptilia by some studies.

Very sad to hear about the passing of Hans Sues. I was always impressed with Hans' breadth across Tetrapoda and his enthusiasm, but he was just a really nice guy above anything else. He was very patient and kind to me as a nervous grad student when handling my first MS, which I have never forgotten.
Oh no. Hearing (via Neil Shubin) that Hans Sues has passed. Woah.

And obviously snakes can wear flip-flops since they're members of the Tetrapoda ("four feet"), and worker ants can fly since they're members of the Hymenoptera ("membrane wing").

The amphibian argument seems to hinge on two points: 1. Juvenile seymourimorphs of the genus Discosauriscus had external gills, and
2. Larval metamorphosis postdates stem tetrapoda

The land animals you're talking about all descended from and are part of the group Tetrapoda (four feet)
It really is just the fact that the ancestors they all trace back to had 4 legs.

There's a lot going on in this paper, but most of its analyses puts Seymouria either just outside Amniota or just outside crown-group Tetrapoda rather than close to modern amphibians. I think "unresolved" is the current state but I wonder if there's confusion between being amphibious vs. amphibian?

Hi, I'm Pascal, a paleontologist from Germany. I'm mostly interested in extinct marine crocs (they got fins!) and why so many terrestrial vertebrates evolved large openings in the back of their skull.
