Supercommunist: They found a mummified homotherium cub. Nov 15, 2024 1:21:50 GMT 5

theropod: Well lol, my government announced it was breaking up on the very same day. Nov 7, 2024 5:57:05 GMT 5

Infinity Blade: We failed you. Nov 6, 2024 23:20:59 GMT 5

theropod: Yes. Shit. I don’t think the free world had any real plan B or contingency for the worst case scenario that has apparently ended up happening. Things were bad enough as it is, and nobody really has any capacity left to deal with it getting even shittier. Nov 6, 2024 19:38:01 GMT 5

Supercommunist: Trump won. Was already pretty pessimistic about climate change but I think I am now in full doomer mode. Nov 6, 2024 12:39:53 GMT 5

Exalt: And the giga not having as wide of a skull Sept 6, 2024 23:05:23 GMT 5

Exalt: I would think that it's because of T.rex striking with power Sept 6, 2024 23:02:54 GMT 5

Infinity Blade: I imagine tyrannosaurs having finesse through their premaxillary teeth. We know they could delicately scrape meat off of bones with those if they wanted to. Aug 28, 2024 1:29:55 GMT 5

Supercommunist: Anyone find it kind of weird how some people portay gigantosaurus as a finese predator compared to a tyrannosaurus? Given that tyrannosaurus had the smaller gape and the duller teeth, wouldn't it require more precision? Aug 27, 2024 23:49:00 GMT 5

Infinity Blade: Maybe Aug 15, 2024 5:02:01 GMT 5

Exalt: Could that be an anti-prefator adaptation, or? Aug 14, 2024 20:32:23 GMT 5

Infinity Blade: I've read that in birds sex only lasts a few seconds, so maybe the fact that intercourse is very brief is an advantage. Aug 12, 2024 7:26:21 GMT 5

Supercommunist: So I can't help but think that cloacas are more prone to STDS and infection that an animal that separates its poop hole and genitals. Are there any real big advantages of having a cloaca? Aug 11, 2024 12:37:19 GMT 5

Infinity Blade: Dinosaur Revolution depicted Gigantoraptor like a bird of paradise, using colors, an inflatable throat sac, and dancing to court a mate. Jul 22, 2024 18:42:46 GMT 5

Exalt: Some birds are known for extravagant courtship displays. Has anyone depicted non-avian dinosaurs doing such a thing? Presumably theropods. Jul 11, 2024 6:31:19 GMT 5

Supercommunist: Cool thanks, Infinity. Jul 6, 2024 9:38:31 GMT 5

razor45dino: 1.2 tonnes is probably a large underestimate or is not representative of a 13 meter individual Jul 6, 2024 7:39:16 GMT 5

Infinity Blade: Assuming the Kaatedocus is 13 m and 1.2 tonnes, however, only gets you ~7.5 tonnes, which is unreasonable. Jul 6, 2024 7:26:59 GMT 5

Infinity Blade: Supercommunist If you scale a 13 m 1.9 t Kaatedocus to Diplodocus' length (24 m), it comes out to be ~12 t. This lines up pretty well with a Diplodocus' body mass at that length. Jul 6, 2024 7:24:20 GMT 5

Supercommunist: I've noticed that baboons seem to gang up on predators far quicker than other social animals. Jul 6, 2024 2:18:30 GMT 5
