Back when I was a kid, dinosaurs were slow, gray, sluggish, stupid, reptilian brutes. The T-rex would go spar with the Tricerotops, the Brontosaur would hang out in the the lake eating water plants and the Pteranodon would be crashing into things because they weren't supposed to be good at flying. All in a colorless, rocky landscape and that was pretty much it. What was REALLY going on is so much more fascinating, the more we dig up the past, the more colored, varied and complex it becomes, I love it.....

Dinosaurs deserve respect by how absolutely EPIC they were, triceratops was an elephant-sized animal with a shield in it's neck and three spears in it's face, t-rex had the strongest bite of all time, sauropods became the biggest land animals of all time, pterosaurs were unlike anything we have today, ranging from frog-mouthed-bat-mupped things to huge azdarchids, that could fly despite being as big as giraffes! You gotta respect the reign of the archosaurs!!!

[@on-jo7716]

Well if this were true you would of been around over 140 years old. Because that's when they thought originally dinosaurs were like that. But even back in my day we thought dinosaurs were giant brute tyrants that killed for sport and eat anything in their path. And herbivores were just walking pieces of stupid meat that couldn't see well and that had shitty senses and couldn't even run well. Which is hilarious compared to modern scientific discoveries. But also it's amazing how we literally are only learning about historical facts as if it's new things we've never heard of like a alien species.

It seems to me from this video, and the wiki page (en.wikipedia.org/wiki/Hell_Creek_Formation) that it was a swampy, humid mixture of California and Florida. People would think that it would be nice to live in (aside from the dinosaurs). NO. Think of how swealteringly hot it would get during the day, and how the swampy humidity being a paradise for Mosquitoes which could carry deadly diseases. A simple stroll would produce more sweat than a run during the middle of the day in Arizona, and the Mosquitoes would be everywhere, and not to mention the swamps and river would be filled with Alligators (en.wikipedia.org/wiki/Brachychampsa). Hell to the no, no, no.

[@nickmitsialis]

RE: the trikes, I'm sure that like lions and cape buffalo they're very very leery of each other and probably don't go out of their way to engage them. But I'm sure many a Rex has profited from hanging around the fringes of a ceratopsian herd during 'rutting season': as males fight among themselves, I'm sure many old alphas get displaced and many young bucks get their butts kicked by THE alpha, not to mention the males will be hormonally distracted and probably more than a few would be injured and isolated to boot. Kind of like white sharks off of elephant seal colonies-sure whites will usually only try to attack subadults, but the bigger more experienced white sharks probably take an opportunity to ambush a 'beta male' who just got mauled and kicked out of the harem by the beach master. No doubt he'd be bloodied up but still in the thrall of the mating season.

[@mothlightmedia1936]

I've heard a paleontologist say that triceratops were solitary animals as adults, there is no evidence for them to form groups and they also "wouldn't have anything to fear" since a tyrannosaurus will prefer something less dangerous

[@nickmitsialis]

@@heito0 Also probably true, but Rexes 'lived fast and died young' so who knows what was on their minds: Sex? Food? Cannibalistic Sex? Maybe tangling with a lone trike will impress a female Rex==especially if he serves it up as a 'wedding dinner'--if he ends up impaled, well them's the breaks. But we can't really know, can we? Recently white shark researchers found several generations of sub adult/teen/pup white sharks that had the same mother and father==I have NO idea how that gets pulled off, unless they're like albatross and meet 'same time next year' at the same place.

[@adampetten5349]

Older juvenile Male lions often take down older juvenile Cape Buffalo. Males are slower than Lionesses but have incredible brute strength. T-Rex did. Fossilization is rare so the lack of injuries could be indicative of T-Rex being very effective hunters.

[@adampetten5349]

Though estimates of 20 KPH is ridiculous...the likely 30-35 kph top speed of adult T'Rex's would make them too slow for Edmontosaurus. Juveniles and Albertasaurus would be the ones with Edmontosaurus injuries. T-Rex was adapted to Hunt slowish and slow large herbivores. It was still fast compared to Triceratops and Ankylosaurus. Pure land scavengers are unknown. Both Hyenas and Neanderthals are effective hunters. My guess is only a very small percentage of T-Rex attacks ended in serious injury so it would be unlikely that such would be Fossilized. Juvenile T-Rex's of 1000-2000 kilograms would be able to hunt the more fleet herbivores and share their meat with the adults in the Pack. I don't think Ankylosaurus or Triceratops were that difficult a match. In addition, high risk attacks would still be avoided. This is why it makes sense that they and Triceratops were social. North American Bison could sustain losses of 500 000 a year to Indigenous people and have a high R factor for large Animals. Identifying Specific Triceratops injuries is tricky as the horns may well break off on T-Rex's massive bones without causing injuries that survive Fossilization. Flesh wounds from a miscalculation of attack would not be apparent on the T-Rex remains.

[@frogtank4407]

T-rex meat would kill a person. Because there were higher levels of toxic metals in the soil during that time, plants would absorb it, and the metal would make its way up the food chain.

[@nickmitsialis]

Another thought RE: Rexes or other Tyrannosaurids(oids?); how do we suppose they hunted. I'm sure a specimen the size of Sue or Scotty is not going to be able to move very fast for very long, but it shouldn't have to, right? If the terrain was 'kind of swamp/forested', here's how I see things go down. The prey animals (hadrosaurs? ceratopsians?) we can assume they're herding animals--IE: they graze in large herds of dozens or maybe larger groups? Presumably dozens of larger herbivores all eating, and grazing near the 'fringes' of the forests. The Rexes probably are 'lurking' or maneuvering around further back out of view. With all those animals tearing plants, trees and brush up and down, munching, breaking, grunting, vocalizing, pooping and peeing and stinking all over the place, a young or inattentive or stupid animal could probably stray too far into the forest or get close enough to a Rex that it could make a short charge.

[@windhelmguard5295]

i had a very different idea, T-rex has the largest eyes of any known land animal, oriented forward for binocular vision, it is also believed to have had an excellent sense of smell which leads me to believe that it hunted by chasing its prey to exhaustion and here is why: the T-rex had longer legs than any of its prey animals would have had, which would have given it several advantages: it could make longer strides, which saves stamina, it could step over smaller rivers and walk through deeper ones which its prey would have had to swim through, it could have stepped over fallen trees which its prey would have had to jump over (jumping is more tiring than running) it could have used its bulk to barrel through undergrowth which would have slowed down smaller animals. it could have used its excellent vision and the elevation of its head to see obstacles that its prey could not, allowing the T-rex to predict the path its prey would take, before its prey could even see that far. it would also be easy for a t-rex to single out the slowest member of a herd simply by watching them try to get away, the slowest member gets left behind and that's what the t-rex will go for.

[@nickmitsialis]

@@windhelmguard5295 Interesting! We know that Rexes and maybe other smaller Tyrannosaurids (Daspletosaurs; Albertosaurs etc) suffer all sorts of injuries between interspecies 'tiffs' and probably resistance from prey as well as things like falls and whatnot. Maybe a sustained pursuit 'shook out' the slower weaker prey animals. I got no doubt the jaws could do the job quickly; And I know folks say that the life of the Rex was hard and it was tough to survive into and beyond adulthood--perhaps many were 'daring but stupid' when it came to hunting...

[@heito0]

I think the fight between triceratops and tyrannosaurus is unlikely, as predators are opportunistic, they prefer not to put themselves at risk, as any injury to a predator usually causes death, since they can't hunt, and infections, like Sue has on his leg, they would probably ambush hadrosaurs, which have far less defenses, that still gigantic animals that wouldn't be easy to kill, juvenile animals, or smaller animals like leptoceratops. an adult triceratops or ankylosaurus would be the last option for a tyrannosaurus, juveniles and injured animals are much easier food

[@usmanya5110]

Being a t rex is not easy. Pretty much Anything is there can cause damage. Looks like ambush is 100% if you're an adult. If you fail good luck Edmontosaurus:this is the largest animal in the hell creek formation with the possibility of it being larger or closer to Shantungosaurus in size. And if they do live in herds mayhem could happen. Think of them charging at a rex and ramming into it or just kicking it's legs Triceratops:Horns.

[@ToolHombre]

Still not buying that just because Trike had horns that we need T-Rex to be injured by one for it to hunt it. The 'sparring T-Rex' scenario is likely a video-game crossover. It fills our fantasies, but doesn't play out well in the real world. We don't consider 'deer wounds' or 'sheep wounds' to be common death causes by Pumas. More Pumas die from car strikes or fights with each other than the injuries of their prey. So horned animals of a similar weight to their predators mainly use those horns for sexual competition. Pumas are likely more worried about running out of stamina to let them get away than they are the horns. They approach from the rear and get the animals running, and massive trauma is given behind the head of the horned animal. Everyone likes to say 'big like Rhino', but Rex was bigger than any living predator. It was also larger than its prey. It's like Rhino vs. a Killer Whale with legs. If it wants to eat Rhino (or Trike) it does so.
