3 Modern Day Animals That Are The Closest Living Relatives Of Iconic Extinct Animals

[@TsukiCove]

At 0:23 I was supposed to say "modern day descendants;" not "ancestors." Thanks @dinogoldie9716 for pointing it out. Please ignore the mistake :)

[@clayalbatross496]

Another interesting thing about Seriemas is that they have a 'sickle claw' on the second toe of each foot, much like the Dromaeosaurids (e.g. Velociraptor, though the sickle claws of these dinosaurs were more robust). This claw is used to help with holding down certain prey items when the bird needs. A recent scientific study on recently-found terror bird foot prints also strongly suggest that terror birds had these sickle claws too! Just thought I'd add those facts to the table.👍

[@johndoherty487]

Serima = Velociraptor Bird Brontornis = Utahraptor Bird

[@timokarff6162]

I do agree with some former comment: If terror birds the size of Kelenken et al. were still around, we would have fewer problems making clear to the general populace that birds indeed are theropod dinosaurs.

[@supertrike5893]

One thing to mention about phorusrhacidae is that they probably didn't die from competition with mamalian predators. Titanis literally lived in a mamal dominant environment and it was doing great there. Also they lived to 0.1 into Pleistocene, over 2 million years after the Great American interchange. So no competition with predators probably wasn't the main factor

[@lamotou4banana383]

It almost certainly was a major factor, Mammalian competitors may have been a factor in reducing Terror Bird diversity, and stiff competition could've meant that when the climate shifted, there was no niche left to shift into

[@supertrike5893]

@@lamotou4banana383 1. I kept using the word probably, not 100% wasn't a factor 2. It has been proposed that reduction of forest caused the terror bird numbers to slowly fall down Tbh even with this in mind, we are still not entirely sure what got terror birds extinct

[@johntodd3910]

Amazing You should’ve add these species Wildebeest: Rusingoryx Paleoloxodon: forest elephant Cave lion: Asian lion

[@TsukiCove]

[@johntodd3910]

@@TsukiCove no problem for largest antelopes video can you include the blue and black wildebeests I think Rusingoryx was related to the blue wildebeests

[@adriani9432]

Cave Lions were not lions, as they belonged to a different species (Panthera spelaea), but their closest extant relatives are lions.

[@tonettalover]

"Even though its sad that the terror birds are gone... " i don't know about you but im pretty glad that 3 metre tall terror birds aren't around anymore.

[@scarylookinhobo]

Absolutely loved this video, just like all the rest! I'm glad you elaborated on the Megalodon not being close to the Great White like everyone assumes! I'd love to give more suggestions for a potential second video as I'm familiar with some extinct fauna. A famous bird named Gastornis is commonly confused as a Terror Bird but was quite different in lineage since it belongs to Anseriformes, meaning its closest relative were ducks and geese! Hell Pigs being related to whales and hippos would be a cool one to mention too!

[@eljanrimsa5843]

But he got it completely wrong with the mako shark. The shortfin mako is more related to the Great White, they are in the same family. Megalodon is in a different family which has no surviving descendants.

[@scarylookinhobo]

@@eljanrimsa5843 true, the megalodon has no descendants, and Tsuki elaborates that many of these entries aren’t descendants but just the closest living relative. What he means by the mako being closer than a white is that the mako is more basal within the family and therefore closer to anyone outside that family. Kinda like how Archaeopteryx would be closer to T. rex than a chicken.

[@mmmmmcola6582]

Great video dude, it's amazing that we know about these prehistoric animals. I could learn about them all day lol

[@teaburg]

Somehow, a living relative of the terror bird pleases me.

[@alvain0204]

Love the video! A few extinct fauna and relatives I could think of would be Mosasaurs(snakes, monitor lizards), Argentavis( Andean Condor), Short Face bears (Andean Spectabled bear), The elephant bird (kiwi birds) And Hast's Eagle (the little eagle)

[@andresdeleon5160]

I love how some modern day animals are related to prehistoric animals

[@DRFishsticks221]

Some? All animals are related to prehistoric animals, every living animal that you see has ancestors that survived the KT mass extinction

[@kaijuar2003]

Well, it has been accepted that Megalodon CAN survive in cold waters. They found evidence that there were different populations of Megalodon. There was a population in the colder waters that could grow to 20 meters. Megalodon went extinct due to the prey species it preferred (whales that couldn't use echolocation like cetotheres) were being displaced by whales that could use echolocation and were either too big or too fast for the shark to catch, it is also because the Great White Sharks were more successful at hunting the cetotheres like Piscobalaena which Megalodon fed on. Megalodon was also too large for its own good. A shark its size would need to eat something equivalent to the size of an orca. Not only that, but fossils also suggest that the population had ALREADY begun to decline as time went on (which usually happens to a species at a certain point in time). Another was LIKELY because of the change in salt contents in the sea (though I'm going to treat this with a grain of salt, pun intended). Comment made: 2:37 PM Wednesday, December 20 2023

[@rebbekahcannons9805]

I had no idea pink fairy armadillo's existed I thought their giant extinct relatives were cool but they're so adorable :o

[@mitchellskene8176]

Psilopterus (a Phorusrhacid), possibly survived until around 100,000 years ago, so it's possible the temporal range of Terror Birds may need an update.

[@TsukiCove]

yes there's always a bit of debate on these things especially when there are new discoveries

[@mitchellskene8176]

[@charlesunderwood6334]

Otodus megalodon was the last of the Otodontidae, a family first appearing in the mid Cretaceous. The relationship between them and other lamniformes is uncertain, but other lamniform families, including the Lamnidae, appeared by the base of the Eocene. It is possible that the Lamnidae arose from the Otodontidae, but just as likely that they came from a Carcharias-like ancestor.

[@creepy6208]

Great video! Im surprised you did not mention the sumatran rhino, since they are closely related to wooly rhinos! In fact, if I remember correctly, they are THE descendents of a population of wooly rhinos that moved south during the ice age, and adapted to the warming enviroment.

[@johndoherty487]

And Asian Elephants are the closest living relative of the Mammoths.

[@GeneralDino-ul8ni]

I can’t lie, Phorusrhachids are badass, it’s a shame that they’re often depicted being fodder to mammals like Smilodon when some would absolutely wreck a Smilodon in a fight. Also it’s most likely that competition wasn’t as significant as we often depict, at least for The North American species “Titanis Walleri”, as it’s more likely The change in climate was their undoing. Also neat fact: Although still debated whether or not it’s still a terror bird, there was a Massive Bird called “Brontornis” that was over 500+ Kilograms in weight, making it one of The largest birds of ever exist! Largest 100% confirmed Terror Bird is either Devincenzia or Kelenken.

[@norbb5526]

[@brainstorm9560]

Arctos simus aka the short-faced bear was a giant ancestor of the modern spectacled bear. On all four it was over 5 feet tall, rearing up on its hindlegs it would have been near 11 feet tall. That's bigger than any modern bear.

Cuz u showed a sloth in the opening I thought u we’re going to do the giant ground sloth as the 3rd animal which would’ve been nice to have them all from South America, cuz then u could’ve made this a mini series doing each other continent n a video about the ocean, or a video for each ocean.

[@yugioht42]

You should look into the Reptomammals, a very unique type of animal that popped up after the dinosaurs. They are distinct because we don’t know too much about them. All we know is that they had both mammalian and reptilian features but did not belong to either family. We don’t even know if they gave birth through eggs or live birth. They are a completely understudied fossil group. This group doesn’t have any modern descendants at all and disappears completely a few million years later towards the giant insect phase of earth. It’s such a strange group of fossils.

Megalodon was the largest shark but not the largest fish. That’s leedsichthys. Also although we only had teeth and vertebrae megalodon remains are definitely not rare!

I thought the largest fish to have ever lived was Leedsichthys but megalodon was still the largest shark/cartilaginous fish to have ever lived.

You can think what you like, of course, but people usually think it's the other way round: Megalodon is the largest fish ever, and Leedsichthys the largest bony fish.
