Being able to simply gaze at a dinosaur skeleton NOT surrounded by a multi-coloured text-book-inna-string with pow-pow fonts and 'DID YOU KNOW that xyz'-messages all over -- imagine that... 💚🥲

Published today in Biological Reviews:

"New perspectives on body size and shape evolution in dinosaurs" - the biggest paper from my PhD (my favourite chapter, too).

Here's a thread outlining some of our key findings. (1/10)

Cover image promoting the new research paper "New perspectives on body size and shape evolution in dinosaurs", written by Matthew Dempsey, Samuel R. R. Cross, Susannah C. R. Maidment, John R. Hutchinson, and Karl T. Bates, and published in Biological Reviews. Image shows a 3D Tyrannosaurus rex skeleton enveloped in simple geometric hulls, accompanied by an artist's impression of T. rex in life.
