Lost Worlds: Hațeg Island

[@adamthespinygiant]

I have a suggestion for a future video: how and why the Kem Kem formation was able to support so many large theropods like Carcharodonotosaurus, Delradromrus and Spinosaurus. Not to mention the other fauna that lived in Northern Africa 95mya that gave the area the name "The River of Giants".

[@Robo_19]

That’s actually a great idea.

@@Robo_19 plus, Spinosaurus is my favorite extinction animal. Just like me, Spiny is allergic to being normal.

[@Robo_19]

@@adamthespinygiant You’re not wrong about that.

[@artieziff345]

Don't know if there's a definitive answer, but the Kem Kem group spans over 5 million years, we don't know if the many species of spinosaurids, carcharodontosaurids and the other large theropods coexisted at the same time

[@Jonnywaffles64]

Actually there were several flightless giant owls on different islands. Prehistoric Crete had its own monster owl that was likely flightless as well.

[@danielmalinen6337]

Hateg Island is a small glimpse of what the European archipelago looked like in the Cretaceous period, and it's good that some other area in Europe gets attention besides the British Isles. And I thank you that Europe can be featured in the paleomedia, because most of the modern media focuses mainly on North American dinosaurs and too little for the dinos of other continents. And Hateg Island is a fascinating phenomenon as an environment and ecology that was no bigger island than modern day Hispaniola in Carribbean. But Hateg was not as lonely as it is assumed, but according to modern computer modeling, it was bordered by chains of archipelagos that formed the mountains of Carpathians and Balkan Mountain surrounding the plain of today's Romania because the Great Adrian was pushed under the rest of Europe. And therefore Hungary, Moldova, Bulgaria and Ukraine were also made up of several islands of different sizes based on geology and fossils. However, Europe's biggest mystery is the Nordic countries, whose fossil layers have been ground away as a result of several ice ages which have been like coarse sandpaper and have peeled away layers down to the bedrock. Fortunately, in Denmark and South Sweden, there are old basins in which Jurassic and Cretaceous layers have been preserved and saved from those ice ages. And thanks to that, in Denmark, for example, it has been found an unpublished remains of unnamed titanosaur, which was no bigger than Hateg's titanosaurs. But of course the rest of Europe is also interesting, like the child-sized abelisaur theropods from France, the mini-pony-sized ceratopsian from Hungary, the dog-sized Struthiosaurus from Germany and the very interesting Concavenator from Spain.

[@flightlesslord2688]

I wouldnt be at all surprised if, like the many dwarf elephants and mammoths that all evolved independently, many different dwarf sauropods existed throughout the Mesozoic on different islands.

[@derkjh]

Don't be Stupid.

[@robotboy719]

A major reason why North American dinosaurs receive so much attention is due to the fact that 1/4 of all dinosaur species discovered are of North American derivation.

[@wuestenfuchsxy]

@@robotboy719 plus USA has the biggest audience for dinosaur media, plus most media creators are from the US no wonder there is such a heavy focus on NA.

Greetings from Romania! 🇹🇩🇹🇩🇹🇩

[@mrAMMW]

Im from romania and never heard that something like that existed here, crazy to think that such an inland place could be an island in the past. Also the Balaur Bondoc animal literally translates to plump dragon which is kinda cute

[@vladkornienko7889]

He was dummy thicc!

[@gydgeza]

there's a place in Salaj we like to visit every now and then to hunt for fossils because it's a really well preserved area of what used to be a shallow seabed millions of years ago. We find fossilized shells, little stone spirals, by the handful. Not to mention nummulites, the place is littered with them

[@petrucercel9855]

​@@gydgeza You would enjoy our subway stations then. You can see thousands of fossils in the marble used to build them.

[@MrMarinus18]

It's not the only remarkable animal place in Romania. Romania also has a cave that's completely sealed off from the world with an entire eco system that's very similar to that of black smokers but on land.

[@Unknown07-ic6kr]

The largest pterosaur wos also discovered there

[@daniell1483]

Hatzegopteryx is my favorite pterosaur, and I'm glad Hateg island gave us this flying giant. I'm not sure if it is precisely the largest flying carnivore, but it has to be damn close! I can't help but imagine the other inhabitants of Hatzeg island living in fear of this apex predator, like a prehistoric dragon or wyvern from famous myth (and D&D). It may not the tallest pterosaur, but who cares?! This animal was just too freaking cool. I bet it is the reason the island got so many votes.

[@bkjeong4302]

It’s the largest flight-capable predator.

[@MrMarinus18]

I think considering it's biology and environment Hatzegopteryx was a poor flyer. That it spend the vast majority of it's time on the ground and only really flew to move from island to island. After all there was no real need for it to fly well since it did all it's hunting on the ground and there were no predators either on either on land or in the air it would have to worry about. So it likely specialized for hunting on land only leaving just enough adaptations for flight so that it could migrate.

[@artieziff345]

Speaking of dwarf dinosaurs, I would really like a video about the Langenberg quarry from Germany, that has to be one of the most interesting Jurassic ecosystems

[@haumea2097]

[@anna_in_aotearoa3166]

Fascinating! As an island-nation dweller, I've always found insular adaptation patterns really interesting (learnt a lot via Atlas Pro's vids), but hadn't ever come across a discussion of those phenomena as they affected dinosaur species.

Would second the ask for some prehistoric Antarctic coverage! Like David, I find the concept of a former semi-tropical forest on that icy continent absolutely fascinating, & it feels like it's a space that just doesn't get much discussion? Maybe because the fossils there have been so hard to access, pre-climate shift...?

I'm personally still a bit suspicious whenever someone shows a Pterosaur just licking up a "small" dinosaur. Even if a dinosaur was the size of a cow, it would still weigh more than a 100 kilograms. It seems unlikely that any animals would pick that up like it is nothing, especially a Pterosaur weighing less than a 1000 kilogram. Wouldn't these large Pterosaurs make a lot more use of their claws rather than just their snout?

With it's head and neck being built as sturdy as they are my guess is that it could rip into and take chunks out of prey items with it's beak.
