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: 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
Supercommunist: Are hybrid snapping turtles legit? I thought they were in different genus but Clint from clint's reptile who has a PHD in zoology once stated he thinks they exist in one of his videos? Jun 8, 2024 8:21:22 GMT 5
Infinity Blade: As for the crocodilian skin thickness question, the most I found so far was a study analyzing three small saltie individuals (the biggest one was 1.93 m). It's called "Histological determination of skin thickness in farmed Australian Crocodylus porosus". Jun 7, 2024 7:20:33 GMT 5
Infinity Blade: I think that's possible. According to Mark Witton, prey animals have been recorded trying to escape predators by going into water, but it often fails. We're not sure why they do this. Jun 7, 2024 7:18:54 GMT 5
Supercommunist: Do you think some theropods would have opportunistically attacked sauropods while they were swimming and their necks easier to reach or is that idea too farfetched to be common? Jun 7, 2024 7:01:00 GMT 5
Supercommunist: Anyone know how thick a large alligator/crocodiles skin is? Despite how common alligator leather is, couldn't find much. A lot of sites say its only a little more than 1 mm thick but I think that was belly skin and I don't know how large the animals were. Jun 5, 2024 22:59:06 GMT 5
Supercommunist: I figured that was the case but every once in awhile you come across a weird animal that breaks the normal rules. Jun 4, 2024 22:10:29 GMT 5
Infinity Blade: Isn't the primary point of scales to prevent moisture loss? I feel like they'd be antithetical to permitting sweating. Jun 4, 2024 16:08:15 GMT 5
Supercommunist: Would it be possible for a scaled animal to develop sweat glands or does that require mammalian like skin? Jun 4, 2024 7:10:13 GMT 5
