Diving gannets #sciart

So as it is always the case with these projects, I signed a bunch of NDAs so I am cannot tell you anything about #PrehistoricPlanetIceAge other than I worked on the series until it premieres Nov 26th So I cannot answer your questions right now 😅

Reconstructions of two robust ornithischians for my library of illustrations available for non exclusive licensing Pachycephalosaurus wyomingensis, a large pachycephalosaur from Late Cretaceous North America, and the ankylosaur Polacanthus foxii from Early Cretaceous Europe #paleoart #dinosaurs

Other highlights include: 🎥 An immersive panoramic video experience of the asteroid impact 🎮 A digital game that introduces visitors to the tools used to track near-Earth objects 🎨 A layered collage, titled “Web of Life,” by artist Clare Celeste And more! Get tickets.👇

☄️Impact: The End of the Age of Dinosaurs opens on November 17! Members see it first! Member Preview Days begin on November 14. Details: bit.ly/4qWC6WP

If you’re at #2025SVP, I’ll be available to chat about this work this afternoon! Our poster on it is at the very end of the balcony (left of the stage) in Hall 3.

#2025SVP @palaeoburke.bsky.social: Endocranial anatomy of gavialoids

🐣 Excited to share our new paper in @globalchangebio.bsky.social ! Using @euring.bsky.social ringing data, we investigated “Phenological plasticity and its temperature-related drivers in common songbirds across Europe.” #Ornithology onlinelibrary.wiley.com/doi/10.1111/...

Our last paper describes the spring-accelerated loop-migration of the Woodchat Shrike, tracked with light- and multi-sensor geolocators link.springer.com/article/10.1... #ornithology

Since it looks like today’s going to be hellishly busy for me, I’ll leave y’all with a question you can entertain yourselves with for a while. Are there any NON-AMNIOTES you’d like to see in PhP Ice Age?

#2025SVP Frewin: New remains are limited (including teeth, a vertebra, and pneumatic ribs) and come from three separate quarries, but enough to establish the presence of at least one theropod taxon larger than Utahraptor. Some features suggest allosauroid affinities.

#2025SVP Frewin: A range of theropods is known from the Yellow Cat Member of the Cedar Mountain Formation, including the large dromaeosaurid Utahraptor. However, until now no larger theropods.

#2025SVP Frewin: Large theropod from the Cedar Mountain Formation

#2025SVP Zanno (via @jgn-paleo.bsky.social): “Jane” differs anatomically from the “Dueling” specimen and the Nanotyrannus holotype, described as a new species of Nanotyrannus. Requires major rethinking of Tyrannosaurus life history and ecology.

#2025SVP Zanno (via @jgn-paleo.bsky.social): Bone histology of ”Dueling” tyrannosauroid shows that it was not a juvenile. It is not plausible that Nanotyrannus specimens could have grown to the size of adult Tyrannosaurus.

#2025SVP Zanno (via @jgn-paleo.bsky.social): Changes required to turn juvenile Nanotyrannus into adult Tyrannosaurus not typical of reptiles. E.g., tooth count is variable in crocodylians, but range of tooth count is diagnostic and doesn’t change through growth.

#2025SVP Zanno (via @jgn-paleo.bsky.social): But is the “Dueling” tyrannosauroid the same species as the Nanotyrannus holotype? Supported by the unique presence of a rostral palatal recess in both.

#2025SVP Zanno (via @jgn-paleo.bsky.social): Tyrannosaurus and Nanotyrannus share a wide back half of the skull, but this is formed differently between the two. “Tyrannosaurus had a wide back of the skull because it had a very wide skull“, whereas Nanotyrannus had a narrow snout.

#2025SVP Zanno (via @jgn-paleo.bsky.social): Why has this been such a challenging problem? Nanotyrannus holotype is a heavily reconstructed isolated skull that doesn’t compare well to similarly sized tyrannosauroids (“Jane”). Some relevant specimens are held in inaccessible private collections.

#2025SVP Zanno (via @jgn-paleo.bsky.social): “Dueling” tyrannosauroid confirms validity of Nanotyrannus

#2025SVP @jgn-paleo.bsky.social: Parallelism and predisplacement in the assembly of the tyrannosaurid body plan, no sharing results.
