However, they lost the spurs. I'm perplexed why: did they evolve with interspecific behavior, of sociobiological relevance, that was somehow lost in hadrosaurs? Lower interspecific agonism? Less mate or nest site competition?

#FossilAdventCalendar Day 11
The #badlands of eastern and central #Alberta 🇨🇦 are probably the best place in the world to find #hadrosaurs ("duck-billed" #dinosaurs like this #Hypacrosaurus in the #CanadianMuseumOfNature). While they're immediately recognizable by their broad mouths and (in many species) large crests, their #teeth also set them apart. Their large, grinding teeth allowed them to chew their food, a behavior that's the norm in us mammals but rare in other #animals.
