How is there still not a usable PhyloCode clade name for the Archelosauria+Lepidosauromorpha node?

Turtles + archosaurs = Archelosauria

ok so squamates and rhynocephalians have more layered skin, but archelosauria do have some layering too. that's interesting.

my favorite part of this as a former evolutionary biologist (who participated in a couple journal clubs on this very topic) is it vindicates my silly pet hypothesis that archosaurs (Archelosauria) are predisposed by evolutionary constraints to yeet their teeth and form beaks instead

tangentially, the paper finds additional support for the archelosauria hypothesis, which posits that testudines are closer to archosaurs than they are to squamates - not relevant to mirasaura, but worth noting

It's #ThursdayBIRDSday today, but we're talking all about archosauria more broadly (and probably *archelosauria,* if we're being honest, with all the turtle discussion that will likely occur)

I love lil snappers, even though they all grow up and eat someone's finger eventually. Best lil Archelosauria

Sim, grupo-irmão de Archosauromorpha, formando Archelosauria (por sua vez grupo-irmão de Lepidosauromorpha)

Reptiles split into a few big groups: turtles & tortoises, crocodiles & alligators, the ancient tuatara, and the huge Squamata group (snakes + lizards).

Pretty simple once you see it laid out.

Hello to the huge influx of followers! I'm Tristan, a MSc student researching fossil #Archelosauria (turtles, crocs, birds, and all their extinct relatives) at #CSUF. I'm currently in my last year of my master's studying a strange fossil #seaturtle discovered in Orange County. Picture from #2024SVP.

カメは主竜類に近縁（主竜亀類 Archelosauriaを支持）、Eunotosaurusはカメの基盤系統にない。
総じて納得。

*Correction because I misspoke: they're not just related to Archelosauria, but are grouped in that clade *together* with archosaurs, who are their closest living relatives.

My understanding is that they *used* to be grouped with anapsids based on skull structure, but more recent genetic research has reclassified them as diapsids. According to this 2022 cladogram, their closest extant relatives are Archelosauria (birds + crocodilians): www.science.org/doi/10.1126/...

Based on this, we propose that supporting cells from Pax2-positive cells is an ancestral feature of Archelosauria, and those cells might be more prone to become steroidogenic. In contrast, in mammals supporting cells derive mostly from cells from the coelomic epithelium.

Thank you, for that.
It must have been awesome to observe them in natural habitat; you're very fortunate!
260 million years of evolution, and they still look what I expected dinosaurs looked like. Today I read that they evolved from Archelosauria, as did birds and crocodilians.

Perfect practice example, I know that Sauria includes reptiles and birds, and that dinosaurs are birds, but the idea that a crocodile is more closely related to a crow than a gecko is just wild
