Apart from the monotremes, the weirdest creatures in Australia are the birds, but for some reason they don’t seem to attract much attention. Australian birds are exceptional in many ways.
Yeah, people talk about the big ones (Emus and Cassowaries) a lot, but not a lot about kookaburas, australian magpies, and various other birds that are unique there.
I am very happy that you’re being sponsored! I have always wondered how such a large continent‘s fauna and flora remained so isolated, even though there were potential land bridges in the past
Sometimes, I wish the continents were more disconnected. A world full of Australias would give so many different animal groups a stage to diversify. Imagine a continent dominated by monotremes or only rodents. I love every video. From the voiceover to the production they are brilliant. I clicked after 29 seconds:D
I live here in Australia and studied ecology in Tasmania. If you ever visit I'd love to meet - I love your videos. I could show you some amazing places.
New World marsupials (opossums) are so interesting. Once you reach central Mexico, more or less, there are more species & genera present than only the common Virginia opossum. So they blend in a lot more, I think, than here in the US, where people call them “giant rats” and stuff. 🙄Yeah, a giant rat with a pouch and 75 teeth instead of gnawing buck teeth…lol. They’re so misunderstood. I wanted one as a pet as a kid. And in a way, nearly got one! Not really. But on my seventh birthday, something told me to look out into the backyard; I watched as a female opossum, with five babies on her back, came clambering down the tree and proceeded to walk RIGHT UP to my window (on the ground floor). Keep in mind my family has had at least three cats at all times, too, which apparently were gone at that time. I was so shocked that this mama opossum would walk up, lay down and take a nap with her babies, RIGHT THERE in front of my window. She slept, but the babies were playing and staring at us. Best birthday gift ever. Hahaha.
Keep the frequency coming!! Love your take on Paleontology and the images you use to illustrate such animals 🙌🏾 Wish there was a Paleontologycon or something like that for nerds like me who find exotic animals and dinosaurs fascinating.
Loved the video! Just so you know though, at 11:16 you should Emu habitat not including a lot of Victoria (that southern bit), but Emus actually come all the way down to the outer reaches of Melbourne. The only reason they're not actually on our streets is because they're pretty skittish.
I truly enjoy your channel. Its incredibly helpful to my understanding that you give timelines, geographies, common ancestry. The full spectrum really solidifies these concepts. Wild about the ostrich and the emu lineages splitting before T Rex existed. That one is gonna sit with me. Just how many bird lineages actually made it through the KPG? Man, nature and life is so amazing.
holy crap i have never seen that tassie tiger video in such high resolution that is crazy love your channel, i have tried a few other biology channels and none of them shine a light (hehe) to your top tier quality
I absolutely love the way you make your videos you're one of the best channels of this genre of video if I have the choice I watch this channel over nearly all others
England sent all their religious people to America. They sent their criminals to Australia. Insert years of booze and fighting and surviving these creatures... Australians.
Kinda wish mammal groups nowadays had more than just the monotremes, marsupials, and placentals. There's a lot of mammal groups that have no modern analogues, like Multituberculates, Meridiolestids, Gondwanatheres, and Eutriconodonts to name a few.
Your videos give just the right amount of depth. You and some others on RUclips give us these great pieces on animals. Please consider doing some on plants too. It’s just as interesting, and it’s an untapped niche on RUclips. Better still, plants are very well represented in the fossil record and archaic species represented in modern flora. It wouldn’t go unappreciated ❤️
13:40 That's an out-of-date estimate. Previous estimates based on site evidence incl.: - 40,000-42,000ya (Lake Mungo, NSW, 1969-1974); - 50,000-65,000 (Malakunanja II, NT, 1985-1994); - 66,000-78,000 (Lake Mungo, NSW, 1999); - 65,000-80,000ya (Madjedbebe, NT, 2008); - 120,000ya (Kimberley, NT, 2019); - 115,000-130,000ya (Moyjil site, VIC, 2019). Earlier estimates have been proposed, but you'll find most of us maintain we lack sufficient surviving, verifiably dated evidence at this time to accept them. AusGovt currently accepts the 2008 estimate as minimum ("at least").
@6:33 "because they had a very narrow pelvis" Monotreme eggs are both small and leathery, so why would a small pelvis mean that the multituberculates would be more likely to be marsupial-like than monotreme-like? Or were their pelvises REALLY tiny?
I thought that was a really good question, so I looked it up. Excerpt from "Mammals from the Age of Dinosaurs: Origins, Evolution, and Structure " "The nature and dimensions of the pelvic girdle bear on the important question of the size of offspring or egg in multituberculates, and so on their mode of reproduction. Kielan-Jaworowska (1979) calculated that if multi- tuberculates were viviparous the maximum width of the head of a newborn Kryptobaatar could not be more than 3.4 mm. This is about 0.13 of the width of mother's head, compared with a ratio of 0.33-0.4 in a rat, 0.45-0.5 in a mouse, and 0.1 in the marsupial Antechinus. If multi- tuberculates were oviparous the space available for the passage of an egg of circular cross section would be even less than 3.4 mm in Kryptobaatar and possibly about 2.2 mm in Chulsanbaatar, which would mean an egg smaller than any known cleidoic egg. In monotremes, in correspondence with their oviparity, the ischial arc is very wide, U-shaped, and structurally very different from that in multituberculates. On the basis of the above data Kielan-Jaworowska (1979) concluded that multitubercu- lates were not oviparous, but viviparous with extremely small neonates, similar to the condition in marsupials."
I think a video about the fauna of prehistoric India when it was an island subcontinent would be very interesting, it is difficult to find information about.
Based on the brains of Marsupials and what is generally known about their intelligence I would say most living marsupials are comparatively more primitive to placental mammals, specifically dogs, pigs, cetaceans, elephants and primates. On average marsupials have less wrinkles in their brains which generally correlates with more complex cognitive ability, obviously they're quite distinct from multi-tuberculates, but compared to placental mammals, if we're going by cognitive ability I'd venture to say they are more "primitive" in this regard. Now it's possible the Tasmanian Tiger was an exception but there's not a lot we know about their cognition since they've all gone extinct.
At the Melbourne Zoo an emu snatched my brother's Choc Wedge icecream from his hand. We were toddlers and are still scared of emus 45 years later 😂. They are beautiful looking though. As are koalas, kangaroos, wallabies, tassie devils, wombats..... Cassowaries are prehistoric freaks. They're scary in real life. They just walk around wherever they want in Mission Beach
Marsupials such as kangaroos do not ditch their young. It’s a common myth. The muscles surrounding the pouch work similarly to our pelvic floor muscles, where they are continuously contracting to hold and keep baby safe in pouch. Sometimes when scared these muscles may temporarily relax causing baby to accidentally fall out. Similar to how we might accidentally wee ourselves when scared. Kangaroos have been known to return and call out for baby.
I believe it was a scientist named Zinsmeister in the 80's who predicted that we should find proto-marsupials in Antartica from 40 mya, one of the great successes of evolutionary theory and biogeography.
The big “South American marsupials” were not marsupials; they were either sparassodonts (not marsupials), or even native placental mammals that are mistakenly assumed to be marsupials in horribly mangled retellings of the (outdated) traditional narrative of the GABI. Also congrats on being sponsored!
@@Lanval_de_Lai It did happen but it wasn’t the “better adapted and more evolved North American animals outcompete and wipe out primitive South American animals” scenario it’s mostly often thought of as.
His definition of marsupial seems to encompass all of clade Marsupialiformes (which includes sparassodonts and other extinct clades) rather restricting it to the crown-group (clade Marsupialia)
