## Resource

Having large body sizes conferred all sorts of advantages on dinosaurs, but it potentially made breeding a bit complicated. This week we take a look at some weird pathologies in fossil hadrosaurs (duck billed dinosaurs and friends) and what they might tell us about their amourous habits - do broken backs provide evidence of rough housing in the bedroom? This week's paper is "Deciphering causes and behaviors: A recurrent pattern of tail injuries in hadrosaurid dinosaurs" by Filippo Bertozzo and colleagues, published in IScience November 2025 https://doi.org/10.1016/j.isci.2025.113739 The widescreen artwork is by Troco.
