kekistani: IN WATER, CHIMPS WILL DROWN. Mar 18, 2021 11:18:01 GMT 5
roninwolf1981: I wonder why is it that the greater apes would drown if they fell into water from the trees? Mar 16, 2021 22:25:11 GMT 5
kekistani: The virgin and bluepilled Mokele Mbembe versus the CHAD and REDPILLED Water Elephant Mar 4, 2021 22:31:57 GMT 5
Ceratodromeus: Considering even the most terrestrially inclined extant crocodilians are also very good swimmers, i see zero reason for sebechids to not be. Feb 25, 2021 21:09:18 GMT 5
Infinity Blade: Virtually every terrestrial animal can swim if it needs to. I don't know about tail flexibility, though. Feb 21, 2021 22:17:14 GMT 5
jhg: Probably not. Terrestrial crocodiles stayed on land for a good reason. Feb 21, 2021 11:17:16 GMT 5
Supercommunist: Do you think sebecids and other crocodile-like terrestrial animals were good swimmers and if so, would they have used their tails to swim or would they have been too stiff? Feb 21, 2021 6:16:35 GMT 5
Infinity Blade: Welcome to World of Animals. Jan 31, 2021 5:06:24 GMT 5
thenormalguy: hello Jan 30, 2021 23:27:49 GMT 5
Infinity Blade: Some pterosaurs have actually been found with pycnofibers on their wing membranes, which might allow for some degree of insulation. www.nature.com/articles/s41559-018-0767-0?platform=hootsuite Jan 23, 2021 9:50:34 GMT 5
Supercommunist: Any idea how well pterosaurs would have fared in extremely cold climates? I can't help but assume that their wing membranes would be more vunerable to frostbite than a bird's wing. Jan 23, 2021 9:38:14 GMT 5
Infinity Blade: 👍🏻 Jan 4, 2021 20:29:04 GMT 5
Supercommunist: Turns out there is a study: www.nature.com/articles/s41598-017-08812-2 fresh bones provided 63% more energy than dry bones but what I find intresting is that dry bones that are between 3-12 months old is still a viable food source for them. Jan 4, 2021 9:18:34 GMT 5
Infinity Blade: I think they might get calcium from the bones, but those might be harder to digest as well. For bone marrow, I'd say however long it's around before it completely decays. Jan 4, 2021 6:23:06 GMT 5
Supercommunist: Question: I know a bearded vulture's diet consists mainly of bone marrow, but are they able to derive nutritional value from old bones or do the bones have to be relatively fresh? Jan 4, 2021 2:59:21 GMT 5
Infinity Blade: Happy New Year mudda fuggas. Jan 1, 2021 10:02:06 GMT 5
kekistani: tarded Jan 1, 2021 8:09:53 GMT 5
Ceratodromeus: nerds Dec 30, 2020 6:30:23 GMT 5
Infinity Blade: Yes! Looking forward to it. Dec 28, 2020 3:57:50 GMT 5
Supercommunist: Apparently there is going to be a 40 min cg documentary on a daeodon and a moropus: twitter.com/digital_duck/status/1342528096176635907. Super excited to see it. Dec 28, 2020 2:57:58 GMT 5
