Makes a lot of sense with how many fossil holocephalians converged on "shark" bauplans, but still really cool

Records show deeper ties between Epstein, ex-Microsoft exec Emails show a yearslong relationship from at least 2010 through 2018, according to documents released to the public last week.

I mean, yes, fun dinosaur stuff is fun dinosaur stuff. But Myhrvold is mentioned in the recent batch of Epstein files over 1000 times (far more than Horner). Some of the correspondence between the two is very chummy and concerning. See: www.seattletimes.com/business/loc....

Haolong dongi, the “Porcupine” Iguanodont. At about 2.5 meters long, not much would stand out about this Hadrosauroid had we just their skeletal remains, but thanks to the preservational nature of the Yixian Formation, we’ve come to uncover amazing details about the anatomy of this animal #sciart 🧵>

Pretty sure nothing happened to this individual. The guy had guns in his hotel room. SVP knew he was an issue in advance and instead of rejecting his abstract, they asked him to edit it to not name specific people in his weird manifesto.

Skeletal reconstruction of specimen DMA-JP-2009/001. Like other metriorhynchids its long with a streamlined body, triangular and deep skull with large eyes, long teeth, a tail fluke and very short arms.
The fossil of DMA-JP-2009/001 as it is preserved. The skeleton is complete and posed in a U-shape, with the head curving up to the right and the tail to the left. A scalebar is shown equivalent to 1 meter.

New paper just dropped finally describing a complete specimen of Dakosaurus maximus and what a beauty it is. Some highlights, in addition to this being a long time coming, is the presence of bitemarks on the face and chondrichthyan material in the stomach

One dramatic advance in evolutionary biology over the past 20 years has been the empirically lead shift in thought, away from rigid species boundaries towards introgression being very common, much of it adaptive. The ramifications are still rippling out (e.g. in ConBio). Below is a nice addition:

Some days ago I made a thread on Pleistocene crocs in honor of Prehistoric Planet: Ice Age, and now I'm bringing it here too.
Let me prefice this by saying that I of course understand their absence, obviously more unique fauna takes priority and I don't begrudge the team their choice

The amount of AI generated art in slides at this conference, primarily used by older scientists, is killing me. Scientists please. Don’t use these ai platforms to make your figures or slides. They look bad and I have yet to see them meaningfully improve the message of talks.

The Case of the Tiny Tyrannosaurus Might Have Been Cracked

My latest for @nytimes.com! For 40 years, paleontologists have grappled over whether a small tyrannosaur — named Nanotyrannus — was its own animal, or simply a teenage T.rex. The debate has been ... contentious. Which is why it's so fun to finally be able to say this:

Folks? Nanotyrannus is real.
