One thing that I have always found extremely fascinating is imagining what life may have existed on Antarctica before it finally broke away from Australia and was doomed to freeze over killing the majority of the plants and animals that inhabited it. This video is the best representation I've ever seen covering the timeline of this taking place! Great job! It cant be overstated how much these events effected life all over the earth, not on just these two continents. The ice that took Antarctica as it slipped away from Tasmania changed the global climate and is believed to have been one of the catalysts that lead to the end of the global hot house of the Paleogene.

One thing I learned from this video was actually the presence of flowers in Australia and Antarctica. For a long time I'd known that flowers did evolve in the Cretaceous period, but I thought flowers were mainly restricted to the northern hemisphere at the time. Now I know they did reach the Southern hemisphere as well during the Cretaceous. By the way I love this channel even though it is very young when this comment is being made. It's providing more knowledge and insight about paleontology and paleoecology. Please keep it up! Heck I'm going to recommend this channel to some of my friends.

Hi Harnawaz Boparai, I'm delighted you love the channel! As long as people continue expressing interest, we'll keep producing content about Australian palaeontology :) It's great to hear what you learnt in this video. Flowering plants reaching Australia by the Early Cretaceous wasn't a popular idea in the 20th century, but it's now become accepted as more and more fossil evidence has come to light. Based on fossil flowers, leaves and microscopic pollen discovered in Australia, we now know that by 108 million years ago 72% of angiosperm lineages, which live in Australia today, had evolved (Korasidis & Wagstaff 2020). Thanks for your support Harnawaz! Definitely feel free to recommend and share the channel around :)

Again, very nicely done! Even though the subject is quite complex and probably rather unfamiliar to many viewers (including me), you guys managed to present it in such a casual, straightforward and enjoyable way! The artwork is also on point. The individual pieces have something light, but yet expressive to them. It almost feels like someone travelled back in time to paint those places and landscapes from life. That is great. And the amount of research that went into the video must have been enormous too! I learned a ton of new stuff while watching this, and feel like having a much more fleshed-out understanding of the area now. Last but not least, regarding the audio quality, the voice-overs in the previous episode felt a bit sloppy here and there, so it is nice to see (and hear) the improvement in this installment. So all in all, great job and I'm looking forward to more!

Hi Daniel Egyed, thanks for your encouraging feedback! :) Honestly you're right, the biggest challenge in these videos is converting the mass of research into compact scripts. Working out how to communicate accurate, complex science in a simple-to-understand and entertaining way. Basically, the aim of the channel is if you have any sort of interest in palaeontology, whether you're new to the field or well-versed, you should be able to take something away from one of our videos. The feedback in the comments, like yours, about how the videos are succeeding or have room for improvement, are really important. So if the videos are coming across as "casual, straightforward and enjoyable" and "feels like someone travelled back in time" sounds like we're doing what the channel says on the tin! Yay!! :D Thanks for your support Daniel. Hope you enjoy our next episode about Leaellynasaura amicagraphica :)

I think that one main reason why this interesting region was warmer than might be expected despite its southerly latitudes is that it preceded (or even prevented) the formation of the Antarctic Circumpolar Current. When the ocean finally swallowed up the land and separated Australia and Antarctica as mentioned at the end of the video, this most powerful current in the world significantly contributed to global cooling - at least according to some researchers - which might seem counterintuitive because the coldest landmass was then much more isolated from the rest of the world. Fantastic video thank you!

Wow. That was really neat. That's a very detailed picture of what that valley was like. I'm surprised there's enough paleontologists or geologists to do the work documenting the different fossils. Maybe research like this fits into the search for oil and natural gas and such. ... It seems like it was a lot of work to make this video. ... It's quite amazing to think of small dinosaurs and tiny mice living together in an Arctic Circle type forest place. If I was one of the small dinosaurs, I would totally hibernate the whole dark winter. This video says they didn't, though, so there must have been something for them to do, even if there was snow. They probably still slept a lot. I suppose most animals are nocturnal, so Arctic Circle type 24 hour darkness would not be such a big deal as it seems, too. I wonder if the dinosaurs and tiny mice had something like bird songs or whale songs that they worked on during their leisure hours. Hmm. ... Lots of great paleoart, too.

To be even more comprehenisve, a short section on microscopic life would be nice. Or were some of these animals or plants microscopic? Anyway, just a thought here. Pictures and some talk about ecology and biology: You can't do too much more than that, geology and climate.

Hi I love this doco. I've only recently become aware of the link between Australia & Antarctica as well as South America. I saw one saying that on deep ice drills remnant's of Aussie & South American flora & fauna were discovered. This is the best doco I've seen with all the details put in on the link between Australia & Antarctica i've seen. Also an emerging theory is that Antarctica is were Atlantis's proponents say it really was now?!?! PS I learnt almost all of what I know on prehistoric Australia from you now. I did plate Teutonic's in Geography in the HSC so I understood the continental drift's well. I'd heard of The Rift Valley though

Although normally, when the vowel I occurs after a letter G, the G is pronounced [dz], in the case of Gippsland it does not. It is named after Sir George Gipps, appointed Governor of NSW in 1837. The G is pronounced in the back of the mouth like "garden".

- Okay, Tasmania trying to separate from the mainland explains a lot. I always found it odd how the evidence of the rift valley was in Victoria when you'd think it would be in Tasmania. - I think you said "Enantiornithis" instead of "Enantiornithine". Small mistakes happen I guess, especially with these big words. :P - Huh, Are both the Otway and Gippsland rocks part of the Eumeralla Formation (with the Wonthaggi Formation being the Gippsland rocks)? I was always operating under the assumption they were different Formations given their different ages and locations, but I guess I can see it. Someone should update Wikipedia lol. - The reason I bring up the above point is because I'm surprised you didn't discuss any of the changes overtime. The Gippsland rocks are older than the Otway ones, and from what I understand that time was also colder (which coincides with that drop in atmospheric carbon dioxide levels you mentioned). It's worth mentioning because from what I understand, Koolasuchus existed during this time because of the colder climate, but I think the Otway rocks also show crocodyliformes, leading some to hypothesise that as things warmed back up they outcompeted the Koolasuchus. That being said... I do wonder if that hypothesis holds up given the freshwater plesiosaurs (something I remember hearing about but forgot until you reminded me here lol). I'd assume they'd have similar niches to aquatic crocodyliformes except they'd be even more aquatic (having flippers and all that). IDK if you have any more info on this but yeah, it's interesting. - Really liked how you explained the actual environments here, which is something I haven't seen many articulate well, so it's nice to properly understand how it all works now. Not to mention all of the aquatic ecosystems too. - Something i've found curious is that the Polar Dinosaurs generally all seem to be smaller than in the rest of the world, and there isn't any island isolation or anything. Do you think it would be down to it being a colder, more forested environment? Like, the largest ornithischians to my knowledge here weren't bigger than 3-4 metres, and the largest predators known were medium sized megaraptorans (probably similar in size to Australovenator?). It's just interesting to me because I'm so used to sauropods everywhere, but I doubt being a giant like that would work in this environment. - Another thing I can't help but find peculiar - ankylosaurs lived here. Even with animals found like Antarctopelta from the final stage of the Cretaceous (from, well, Antarctica), I've always had a weird time picturing them as polar animals. I think one of the species they uncovered was even kind of small even for others of its group. Anyway rambles aside, really enjoyed seeing this. This has always been one of my favourite palaeoenvironments to think about, and besides Walking With Dinosaurs and some books not many people take note of it, even if we're full of our surprising amounts of fish and mammal fossils here (huh that reminds me: I think Teinolophos is the oldest known monotreme, and over in the Otways we have Kryoryctes cadburyi... yes they named an extinct monotreme after Cadbury chocolate lol). I'm probably biased because I'm from Melbourne and love to have a tangible idea of what things were actually like here in the Mesozoic (I actually went to the Dinosaur Cove area for my 15th birthday lol), but I do still think this is a pretty unique environment compared to a lot of what we know. Like, even the polar fauna of Cretaceous Alaska isn't too different from the rest of Laramidia, here we seem strange even for Gondwanan standards.

Hi TyrannoNoddy! This video was a lot of work to research, film and edit so I'm incredibly grateful that you enjoy the content. I did laugh out loud when I found out about Kryoryctes cadburyi in my research! You are so lucky to have visited Dinosaur Cove. I haven't visited Dinosaur Cove, but I did visit Inverloch to check out some fossils at the Bunurong Environment Centre. And take a selfie of me with the life-sized Koolasuchus statue at the local park! Good times haha. Okay, I will address your points as best I can :P - Pronunciation is indeed not my strong point haha! I mispronounced "Diluvicursor" and "Gippsland" a few times. However, in this case, Enantiornithes and Enantiornithine can be both used interchangeably :) - The Wonthaggi Formation was re-named the Eumeralla Formation in 2006 because they both mostly align with the same ages (Aptian and Albian). However, you are correct, that the Wonthaggi Formation rocks are a little older at 129 MYA, compared to Eumeralla Formation's maximum age of 125 MYA. Wikipedia is indeed outdated I'm afraid haha. Here are my sources if you wanted to check them out: Wonthaggi Formation: asud.ga.gov.au/search-stratigraphic-units/results/33943 Eumeralla Formation: asud.ga.gov.au/search-stratigraphic-units/results/6363 - You have indeed pointed out a missed opportunity in this video to have a timeline following the change in climate over time. I will be touching on climate change in Episode 4 about Koolasuchus, if that's any consolation :) - There's not enough fossil data to draw conclusions, but my guess is that freshwater plesiosaurs and pliosaurs already occupied different ecological niches to Koolasuchus. I'll see if I can find more information on this idea before Episode 4 premieres in May. - Thanks :) I do feel that paleoenvironments and plant life don't often get the attention they deserve. I'm glad you feel the same way! I do believe the best way to communicate the science of paleoenvironments to a wider audience is to provide evocative, simple-to-understand illustrations of what the world was really like. When you do that, then anyone can understand and foster an interest in paleoenvironments. Just my two cents :P - You are right! I haven't touched much on Victorian ornithischian size in the upcoming Episode 3 on Leaellynasaura, but I'm pretty sure Tom Rich did write a paper on that very subject. He proposed that theory, linking the common fossil finds of small dinosaurs in Victoria to its position as a polar region in the Cretaceous. Even if large dinosaurs migrated to the area seasonally (of which, there is no evidence of this behaviour in the region), it is unlikely the small ornithischians engaged in annual migration. If I find the paper I'm thinking of, I'll post it here for you :) - Ankylosaurs did indeed live in the Antarctic-Australian Rift Valley. In an earlier draft of the script I mentioned their presence, as well as several possible theropod groups, but it was cut for time from the final script. ((In the end, we had to cut 10 minutes because my editor said my script was "going off on tangents" hahaha. Honestly though, he was correct in his assessment. Although, you did miss out on me rambling about deciduous and evergreen plants for 5 minutes :P )) Anyway, TyrannoNoddy, thank you so much for your support as usual. I enjoy your comments and chatting with fellow fans of Australian palaeontology like yourself :) Hope you enjoy our next episode about Leaellynasaura amicagraphica!
