Desmostylians were a very strange-looking group of mysterious animals that lived for millions of years before disappearing, becoming the only known order of marine mammals to die out.

Well this is what they believe, though much of what is believed cannot be proven. Even environment, at time, isnt known well. Sea-cows, helped, though it is likely an unknown force played a part, as it nearly wiped out Dungongs. Whatever caused it happened fast. Some ancient whales disappeared about this time. A theory, I've heard, Ocean waters changed, sometimes it is more acidic and sometimes salt percentage changes. While this creature wouldn't be bothered by these two, food sources would be. Final issue, we know not much about these animals, fossil records are not great for such, thus what is known and view able very limited. Creature at 4:17 is an Embrithopoda.

@@cacogenicist Possible, fossil record, though limited, doesn't suggest this. And if it did change, question be what would cause this? What you said, is one theory among many. Just there is no evidence of this happening. Because of limited fossil record, it very well could have happened and just never saved in fossils. My theory, since many creatures, including "sea-cows" were nearly wiped out, is a climate change happened. This would cause vegetation change like you said to happen. Just no evidence of a majour climate change, Earth climate does change all the time, it is normal, our current one is simply a minor one compared to what was going on millions of years ago. So, I accept what you said as valid, and ty for reply.

I seriously doubt that sirenians drove these extinct. Marine food chains are too productive, and the ocean too prone to conserving niches, which is why no other order of marine mammal has gone extinct. The desmostylians did however inhabit the higher latitudes of the North Pacific, an environment that has sharply changed over the Neogene, in particular growing colder after the Miocene Climate Optimum. Possibly the specific type of plant community desmostylians depended on went extinct due to the change in environmental regime, and/or the desmostylians were less adaptable to the cold than the Sirenians. A candidate would be seagrass. A transition to kelp-based communities at higher latitudes from seagrass, or whatever other plant, with the onset of colder waters, might have done in the Desmostylians. Note that Wikipedia's citation for Desmostylians eating kelp offers nothing more than a statement that both desmos and sirenians probably ate kelp, with no evidence to support that.

Well, well. The main reason no other order of marine mammal has gone extinct, is there aren't that many other such orders, just 2. Just cetaceans (whales) and sirenians (sea cows). And on closer look, the cetaceans have lost their separate order already and are now part of Artiodactyla. The sirenians still have their own order, but only because they look so distinctive. If they wouldn't look so different, based on how recently they evolved, we probably would lump sirenians into an order together with elephants and hyraxes.

@chir0pter 5 жыл бұрын
@@eljanrimsa5843 True, one can't make too much about the level of hierarchical distinctness here, as that is a judgement call by humans and different standards are used in different branches of life. It's also true there are some holes in an ecosystem-shift interpretation- such as why the Desmostylians didn't retreat to warmer waters in SE Asia. Perhaps they did, and we just haven't found fossils yet of a late-surviving population. Perhaps the rise of pack-hunting orcas or other predatory odontocetes drove them extinct- orcas first appeared in the late Miocene, and it's notable that even today the diversity of sirenians is low, with the only high-latitude North Pacific representative (Steller's sea cow) recently extinct due to (human) hunting pressure. Or perhaps there was indeed something unique about the higher-latitude North Pacific ecosystem prior to the cooling of climate, or a combination of the above. It just strikes me as unlikely that a large mammalian herbivore would drive extinct another large mammalian herbivore due to competitive exclusion in such productive ecosystems, typically we see guilds of diverse mammalian herbivores on land.

It's interesting that they were outcompeted in the Pacific, the eastern Pacific doesn't have any large marine mammals that feed on kelp and fill this ecological niche anymore. I would guess this is due to climate change, and the ice age essentially destroying the habitat that made this way of life possible.

We're living on the side of the fault that is continuing to rise ever so slowly and never stops. The impassable mountains behind the Sunshine Coast small town Powell River BC. Has to have something up there. The first thing seen way up at the head of the last roads made wind up along side a old River Bed that is Epic and Looks straight up millions/ billions of years old. I swear one day I will show y'all what things people should have been pulling out of the highest mountain passes and valleys below as I KNOW there is stuff that has found it's way up there. Only in seclusion will one find safety right. And predators live up high it masks their scent and they can prowl the lowlands. And all the biggest animals are up there. Grizzlies and MASSIVE ELK. Brown and black bear. The deer are even way bigger up in the high lands. We are close to Ocean level here. And the mountains behind us only foot travel will allow one to pass them.
