#temnovember2025 day 7 : Micropholis
For day 7 of #temnovember we have #Micropholis a small #temnospondyl from Southafrica and Antartica, notable for being the only Triassic #dissorophoid

Took me days to do this piece. Finally getting my hands on the weird dissorophoid Platyhystrix rugosus. First time trying to create a scene, pls do leave appreciative comment if you can...

In 2006 an early Permian Varanops skeleton was described with scavenging traces on its bones. The bite marks and an embedded tooth match a dissorophoid temnospondyl, something like this Cacops on the right. #FossilFriday

Adding some plausible speculative soft tissue for a terrestrial dissorophoid really makes it look that way

Then, last year, ahead of my visit to the Smithsonian, my colleague Arjan Mann was in the bowels of the collections looking for an unpublished Texas dissorophoid specimen that another colleague, Bob Hook, wanted me to look at. While there, Arjan found another unpublished Texas dissorophoid (8/n)

@calamanderso.bsky.social is already using another dataset that contains more than 1,700 skull length measurements/estimates, which is compiled in part from my frequent depiction of size for various clades in some of my recent work (note that skull size is only a pseudo-proxy for body size)

メイソン・クリークにおける両生類高次多様性と初期適応放散の証明:
従来 Amphibamus grandiceps 単一種とされていたメイソン・クリークに、少なくとも 4 分類群以上のアンフィバムス形類が共存していたことを明示し、石炭紀における初期有頭足類幹群の急速な形態的・生態的適応放散を立証した。

Lepospondyli and Holospondyli are falsified, with a clade of urocordylids and aistopods, having temnospondyl, but not dissorophoid or lissamphibian affinities. They did not fall into the tetrapod stem, but were temnospondyls, just as 'microsaurs' are reptilomorphs, apical to the seymouriamorphs.
