And that’s not even counting the keratin sheath. Allosaurus had impressively sized toe claws too.

The pelves of Dreadnoughtus, Tyrannosaurus, and Giganotosaurus to scale. I can't help but wonder if this was prompted by a quote tweet I made about his T. rex-Dreadnoughtus size comparison (regarding ilium size). Source->

A couple of my more recent size comparisons:

Typical and very large adult megalodon compared to their equivalents in the great white shark:

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

Supercommunist: Random question but do the weight estimates for Kaatedocus siberi look accurate? it was apparently 10 to 13 meters long and the sources I have seen state it was 1.2 to 1.9 tonnes. Jun 30, 2024 12:34:37 GMT 5

Infinity Blade: Developing it overtime would seem simpler and more intuitive IMO. Slowly, as the animal grows, it gets more and more wary of steep surfaces. Jun 26, 2024 6:34:12 GMT 5

Supercommunist: Do you think multi ton species have an innate aversion to walking off steep ledges or is that something they develop overtime? Jun 26, 2024 6:17:36 GMT 5

Infinity Blade: Tbh this is my first time hearing of snapping turtle hybrids, and a lot of what I found on the Internet is limited to social media and YouTube. Jun 8, 2024 9:01:41 GMT 5

Supercommunist: Also found some info on alligator skin according to one source, an alligator osteoderm was 15mm thick. The size of the animal wasn;t mentioned. Sun, C.-Y., & Chen, P.-Y. (2013). Structural design and mechanical behavior of alligator Jun 8, 2024 8:27:58 GMT 5
