The New Dinosaurs: an alternative evolution Published in Historical Biology: An International Journal of Paleobiology (Ahead of Print, 2026)

My long review of the 2025 edition of Dougal Dixon's The New Dinosaurs has just been published in Historical Biology. What is the 'use' of Speculative Zoology and how does this book connect to the history of dinosaur research? www.tandfonline.com/eprint/YTPSK... #SpecZoo #SpecBio

A photo of a lesser Madagascar hedgehog tenrec  enrolled into a ball. The animal is grayish in color, with white spikes on its back and a long snout.

Did you know? The lesser Madagascar hedgehog tenrec is more closely related to elephants than true hedgehogs! Weighing ~0.25 lb (0.2 kg), this small mammal inhabits western Madagascar. It can roll up into a spiky ball to defend itself from foes.

Long-necked theropod dinosaur model with scruffy grey feathers on its body. In a case with a worn-out label that identifies it as Syntarsus.

opposite side, which has exposed skeleton. There's some variation in color and texture of the bones, but I imagine they're all casts.

A "Syntarsus" half mount at the National Museum of Zimbabwe (via my colleague who always gets to travel to cool places). Interesting that it has both feathers and a dragging tail.

Another illustration for my upcoming children’s deep sea book, these are Lammelibrachia tube worms and some Alvinocarid Shrimp from one of the two cold seeps spreads.

Unlike the baitball segment from LOOP E01 (which emphasizes 'convergence of lineages' and fails to articulate even that), #TheDinosaurs 's first segment aims only to immerse the audience and show the full diversity of dinosaurs at the peak of their reign. It does both splendidly.

This dead Ankylosaurus is in fact a practical FX model made by Mangostone (who also made the skeletons from PhP openings and the dead nodosaur from Surviving Earth)!

Happy #FossilFriday here is a wee climate paper that I coauthored. We found that 20kya eastern Washington was drying and warming up and chasing away all the pesky pine trees (ew, trees).
