Brought out from a discussion elsenet: would Earth now be warm enough to support large, #nonavian #dinosaurs today? This is a fair question, because as bad as global warming is—and it's going to get worse—we're still nowhere near the hottest times of the #Mesozoic.
The answer is, it was *generally* warmer than the present day, but #global #temperatures went up and down considerably, as you'd expect over such a long stretch of time—about 175 million years from the first dinosaurs to the #Chicxulub impact. Dinosaurs as a #clade did fine the whole way through, although of course with plenty of various groups dying out in the meantime.
Also, the planet has always had warmer and cooler regions. Many large dinosaurs lived comfortably in polar regions that had #climates comparable to the cooler parts of the temperate zones today. The idea that non-avian dinosaurs exclusively inhabited steaming jungles or baking deserts has been embedded by generations of paleoart, but it's just wrong. If the impact hadn't happened, they'd still be thriving.
That being said, #sauropods in particular seemed to prefer warmer environments, so their range might be a lot more limited now than it was then, and it's possible the ice age(s) would have finished them off. Other famous giants like #tyrannosaurs, #ceratopsians, and #hadrosaurs would still be widespread, and smaller ones like #dromaeosaurs ("raptors") would be as numerous as coyotes and wildcats are in our world.

Plant-eating #dinosaurs evolved backup teeth to eat tough food, research reveals https://phys.org/news/2024-08-dinosaurs-evolved-backup-teeth-tough.html
Trophic evolution in ornithopod dinosaurs revealed by dental wear https://www.nature.com/articles/s41467-024-51697-9
"At the end of the #Cretaceous, the duck-billed #hadrosaurs were the most advanced #herbivores on Earth. New research has revealed just how voracious these dinosaurs were, with their average tooth worn away in less than two months as they consumed enormous amounts of #plants."

"Corythosaurus casuarius" — 2012
Corythosaurus casuarius was a duckbilled dinosaur, from the Late Cretaceous of North America. This a a completely reworked version of the first painting I ever did, back in 1995 or so. It owes quite a lot to a drawing of Parasaurlophus in a redwood forest by Gregory Paul.

@futurebird @apophis @stevegis_ssg @DemonTomatoDave
in this podcast, Dr. Ali Nabavizadeh gives a great explanation of the differences between reptile lips, which don't have muscles, and mammmal lips, which do:
https://terriblelizards.libsyn.com/tls08e07-chewing-triceratops-with-ali-nabavizadehOf course it's inside a discussion on whether or not dinosaurs had lips. : ) It's about 30 minutes in.

#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.
