My latest for National Geographic! A new study suggests that you really, *really* would not want to be hit by a lunging mosasaur
nationalgeographic.com
This Cretaceous 'Sea Monster' Attacked Prey Faster than Great White Sharks
By analyzing tail length and muscle power, paleontologists have explained the physics behind a mosasaur's deadly ability to lunge toward its prey.

"Where do turtles belong on the reptile family tree?" is one of those questions that seems like a no-brainer. In actual fact, when you take a step back, turtles are *extremely* weird! I wrote about it for National Geographic

What, Exactly, Is a Turtle?
Paleontologists have resolved a decades-old debate over turtle evolution in a new study of 210-million-year-old skull fossils.

"The plan is to kill off publicly funded academic science in this country." Correct. And that means killing off the whole US science and innovation industry. Because it's all built on a foundation of basic research—which. can. only. be. funded. by. public. dollars.

Yes they are, they are probably pretty closely related to snakes and monitor lizards but it's still a bit inconclusive exactly where they sit

At the time I was always baffled how season 8 got so much hate when I firmly believed (and still stand by this) that season 7 was significantly worse.

Christian Halliwell @pryftan213.bsky.social · 05/05/2026
My opinion was always that the last couple episodes were largely pretty solid and that a fair amount of the way the story was concluded actually works really well (saying this as a book reader), but that the the last two-three seasons overall did a very poor job of building up to that ending

Important new paper! A fragmentary but super early fossil cetacean: introdocing Kalakocetus from the early Eocene of India. It's got molars that are intermediate between the herbivorous raoellids (cetacean sister taxa) and the carnivorous early whales like Pakicetus. www.nature.com/articles/s41...

Most of the teeth are triangular and double rooted; the mandible is small, around 20 cm long.A phylogenetic tree showing the placement of Kalakocetus as the earliest diverging cetacean, branching off before Pakicetus and later archaeocetes. The tooth morphology is intermediate between the herbivorous raoellids and the carnivorous pakicetidsTooth wear in early cetaceans, showing that Kalakocetus has tooth wear intermediate between raoellids and early whales

It's not a specifically nazi-originated thing, but it derives from early (incredibly racist) anthropology and eugenicism - which is also where a lot of nazi ideology came from to begin with.

Largely personal preference things - the Prehistoric Planet mosasaurs are pretty good but they lean, imo, a little too far in the whale direction whereas The Dinosaurs Tylosaurus hits that sweet spot of looking like a very specialized aquatic lizard.

In terms of the actual design, I would definitely say so. Prehistoric Planet's mosasaurs left a bit to be desired for me in that respect, especially compared to the wonderful plesiosaurs and azhdarchids, etc. As a show though, Prehistoric Planet sweeps for sure.
