T. rex debate settled: contested fossils are smaller rival species, not juveniles

New evidence answers the question about whether some fossils are Tyrannosaurus rex juveniles or a different species, with implications for decades of published science.

Pterosaur holoptypes! Klobiodon, Plataleorhynchus, Cimoliopterus, and Coloborhynchus

Holotype of Klobiodon rochei. It is most of a jaw, encased in matrix. The front of the lower jaw is downcurved and has a short upturned hook at the front. There are four spiky teeth

Holotype of Plataleorhynchus streptophorodon. It is a long, flat beak with an expanded spoon-shaped tip. Very much like a spoonbill, except it had little teeth lining the entire jaw

Holotype of Cimoliopterus cuvieri. It is the front part of the snout. It’s slightly upturned, and has and a trapezoidal crest and a bunch of tooth sockets

Holotype of Coloborhynchus clavirostris. It is a very chunky snout tip with a flattened front, the base of a large crest, and a bunch of sockets for large teeth

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.

Blast from the past: Old digital flyer from the early 2010s showcasing some off the palaeo and sci vis work I'd done over the years as a freelancer. Much water passed under the bridge since then, but I'm still available for hire! #scivis #sciart

We have lost the pillar of Scottish vertebrate palaeontology, Dugie Ross. The man that found & named Dearc. He made the science resonate locally, in his native language, on his native soil, while allowing it to grow globally. He embodied the best of science. Immeasurable loss.

Delighted to see this new paper out on the Cretaceous turtle Rhinochelys from the Lebanese Lagerstätten in Nammoura (approx 100 mya).

This is the oldest direct evidence of sea turtle soft tissues, and shows that sea turtles lost their scales 4 independent times
