We return to #temnovember with a little guy, #Conjunctio, a small #dissorophid from lower permian on New Mexico. Also its name soounds really close to spell in spanish, so Magic Frog;)

Scientific breakthroughs are rarely unique; someone else would’ve made them soon enough. But when prominent scientists cause harm, that harm isn’t inevitable; the world might simply have been better had the harm not been inflicted.

(Recent art) Ceratodus nargan Illustration!
Ceratodus is a wide spread prehistoric lungfish species that is related to the extant queensland lungfish. Here lies a species in the Early Cretaceous of Southern Victoria, Australia, in the Euremella formation.

New paper in JSP: Gonçalves & Luccisano reassess the taxonomy and phylogeny of Aeduellidae, Carboniferous ray-finned fish from Decazeville Basin, France 🐟
Results hint at a North American origin… or convergent traits that muddy the family waters.

One of the largest temmnospondyls ever to exist: the gigantic Koolasuchus was also the last non-lissamphibian temnospondyl to exist. It survived into the Early Cretaceous of Australia when all other stereospondyls were long gone

RRR is so mad he's making up sutures and bones. No idea how this made it through peer review. To quote a totally unacceptable comment in a referee report by the second author on this paper, "perhaps it was pal reviewed"

Loving this Nanotyrannus news. From a philsci perspective, the discourse around small Maastrichtian tyrannosaurs has deviated profoundly from the more widely applied standards of the field, so seeing this debate finally settled is very satisfying.

We need to be more honest about the nature of the job market with students, and one way of doing that is by showing them the data. Turns out, we also need better data collection on (at least US) paleo careers www.cambridge.org/core/journal...

This is a super cool paper from the Hejnol group that should be a top reference for a lot of animal biodiversity/zoology courses.....origins of the bilaterian anus from the gonopore. Just drop this figure right into your slide deck.

This #fossilfriday , I wanted to post a very classic Pittsburgh fossil. This is Fedexia striegeli. It’s known from only one specimen (shown here) that was collected during a geology field trip to a roadcut near Pittsburgh in 2004. I credit it as the specimen that made me interested in local verts!

Trump slammed for demolishing White House before Canadians could burn it down again
WASHINGTON D.C. - US President Donald Trump's planned White House ballroom, requiring the complete demolition of the historic East Wing, is being criticized by Canadians who will now never get to light the building on fire for a second time since the War of 1812.

People on twitter are losing their minds over this, including several scientists who I have to assume have either brain poisoned themselves or were always like this. People don't always cite what's best; they cite what they know & researchers from historically excluded communities get the short end.

I know there are more important thing to be upset about right now, but I just want everyone to be mentally prepared for the Trump Whitehouse Ballroom social media "reveal" which is just AI slop of Trump dancing the Gangnam Style dance while ACDC's "Big Balls" plays in the background

This clarity and the ability of the ICM to be clearly shown to be wrong is a virtue worth emulating in other work that seeks to connect development, variation, and evolution. We can encourage this spirit by taking the rejection of popular and appealing theories a bit more seriously. 22/22
