This month my patrons voted on the monthly paleo catalog video to be about the biggest bird to ever exist. A member of the same group of birds that includes the ostrich, the emu and even the extinct Moa of New Zealand. But this was by far the largest of all of this flightless birds. And around this creature is a mystery about exactly how and when this 1600 pound behemoth disappeared. I get to study how this animal became such a massive beast as well getting to see the monstrous egg that it laid. And we find out the very surprising answer to the question 'what is it's closest living relative today?'
This also begins a new monthly project that my patrons and I will begin working on where I get more in depth studying the unique environments of islands throughout time as well as the amazing animals that came to call these lost worlds home!

Dont forget about lakes, AKA reverse islands. Some of the most interesting examples of this phenomenon are in likes such as Lake Baikal, Lake Matano, Lake Titicaca, and the various African rift lakes. Lake Baikal in particular is a very strange place, it even has very difficult to explain seals.

@eljanrimsa5843 Год назад

The seals are just normal seals. They have not been separated from other seals long enough to evolve anything special. The giant Lake Baikal freshwater sponges are the real evolutionary showstoppers.

@Exquailibur Год назад

The fact the seals are so typical is what makes them strange, they are most closely related to the Caspian seal which lives very far away. We also just dont know how they got there or how long they have been there in general. Also the sponges are really cool, same with amphipods. Its basically a mini ocean, too bad its not being well managed.

@Dell-ol6hb Год назад

@@eljanrimsa5843 the reason the seals are interesting is because we still don't really know how tf they even got to Lake Baikal, their closest relatives live like 4400 km away

@eljanrimsa5843 Год назад

@@Dell-ol6hb There were multiple occasions when Lake Baikal and the Caspian Sea where it's nearest relative live were linked via giant glacial lakes and remnants of the ancient Tethys Ocean. Because there was more than one occasion we can't tell which one it was, that's the whole mystery here. I guess scientists would need a fossil from an intermediate form somewhere before they can say more about this.

The Elephant Bird is truly the BIGGEST BIRD 🦤

@icarusbinns3156 Год назад

I learned about the elephant bird around age 7? And was OBSESSED! On a family trip to the zoo, a keeper was talking about flightless birds, and had eggs on display. She had a chicken egg for reference. When I asked what bird the biggest egg came from, she said, “Take a guess. Where do you think it came from?” I happily answered, “The elephant bird!” I had no idea they were extinct yet! This poor woman was shocked, and completely speechless. After a bit, she looked at Mom, who just sighed and said, “She learned about them two months ago. The library has had to request obscure books from elsewhere so she can keep reading about this bird.” The keeper finally told me, “That’s a pretty good guess, but I don’t have any of those. This egg came from an ostrich, though. Those are the biggest living birds in the world. I’m sorry that the elephant bird is long gone… like the dinosaurs.”

@gshaindrich Год назад

"I’m sorry that the elephant bird is long gone… like the dinosaurs" ... of course that is wrong, sadly most people don´t know that, almost every week from paleo-youtubers to Elon Musk always claiming "the dinosaurs died out" when they didn´t. Sadly dying out is true for moas and madagassian giants, both like others eg the dodo and Rodriguez solitaire being wipe out by humans. "The library has had to request obscure books from elsewhere" ... sigh, yeah adults would like to keep children dumb

@martijn9568 Год назад

Hats off to the keeper for acknowledging that she didn't really know much about the Elephant Birds. Your story also reminds me of my long forgotten quest of finding information on certain extinct tree species included in the video game Zoo Tycoon: Dinosaur Digs. The poor man at the museum couldn't help me with that quest or my broken Latin when I was 10.😅

Really enjoyed your video! Having spent the 1970s In Hawaii, I became fascinated with the local ecosystems, and with island ecology in general. One of my main references at the time was "Island Ecology," by Sherwin Carlquist. It has probably gotten dated by now, but it's worth looking for. One of the many peculiar Hawaiian ecosystems is that found in lava tubes, which are caves left behind by flowing lava. The only energy input to these little mini-ecosystems is tree roots growing down through the ceilings of these caves, so each cave has evolved its own suite of critters that feed on the roots, or feed on the critters that eat the roots. There are blind wolf spiders, and a bunch of blind insects as well. Then there are the carnivorous inchworms, which feed on any of the hundreds of Drosophila (fruit fly) species. And the giant dragonflies...I could go on and on... And other island groups have equally interesting ecosystems. There are lots of ways to go if you're interested in studying island ecosystems!

The fact that humans and Elephant Birds coexisted for so long before the Elephant Birds died out probably points to less predation of these animals by humans. I imagine that there were some efforts by the inhabitants of Madagascar to limit their hunting of these birds as they became rarer. I personally have my suspicions that this wasn't the only case where humans actually limited their impact on the environment, because the Greenland Norsemen did the same when it came to hunting seals. Rather than hunting the land-going seals they focused on the ice sheet staying seals, otherwise those other seals would have quickly died out. The probably a whole branch of archeology and biology(and probably history) that focuses on this question as it would be too easy to say humans did it and leave it at that. Besides that, I didn't even realise that there probably existed multiple species of Elephant Birds😅

@Alister222222 Год назад

I would argue that many species grow larger not because of the lack of predators, but because it puts them, or more specifically their offspring, in the 'too big' range for predators. In my country of New Zealand, we have kiwis, which aren't large, but have the largest egg by bodyweight of any bird. Baby kiwis are just big enough to be safe from moreporks, the main nocturnal predator in pre-European New Zealand. We also had the moa, which was preyed upon by the Haast's eagle, and which would explain its large size. The larger they grew, the safer they would be from the giant eagles. This would also explain why the Haast's eagle grew so large, as they were in an arms race with the largest birds on the island.

Ratites, or paleognaths, are weird in general, and almost seem to be predisposed to evolving away derived bird traits. Recent fossil evidence suggests that, unlike previously thought, their jaw structure (which is simpler than in any other living bird, causing their beak to be far less mobile) is not a basal trait that they retained because they separated from the last common ancestor between them and all other living birds(the neognaths) before the evolution of a more mobile beak, but that their ancestors used to have a neognath jaw structure and lost it in favor of a structure more similar to non-avian dinosaurs and pre-modern avians. They've also repeatedly evolved flightlesness (obviously not the only birds to do so, but every living ratite is either completely flightless or at best only capable of short-distance flight, and ratites have repeatedly lost the ability to fly even when not living on islands) and more "primitive" feathers (something not seen in all flightless birds: the kakapo and dodo for example don't display this, though neither do all ratites). There just seems to something about these birds that seems to make them try very hard to evolve back into non-avian theropods.

It should be remembered that the elephant bird and co. survived the glacial and interglacial periods of our current ice age. This means it survived the forests contracting and expanding; the birds were under stress and then able to regrow its numbers when more favoured climatic conditions returned. It was humans, the ancestors of the Malagasy, and all they do, that caused the death knell of the elephant bird.
