You or your scriptwriter seem to have gotten cassowaries (big, dangerous birds from Australia) confused with ostriches (that are from *Africa*).

I’m pretty sure as far as Australian birds go the cassowary it the most likely to unalive you

Titanoboa looks like he's about to petrify some mudbloods.

you won't be finding any wild ostrich in Australia and very few in captivity, instead you'll find the emu which is a much smaller yet still very large flightless bird, although the cassowary is considered to be much more aggressive and likely to kill you

2:45 - That guy behind Andrewsarchus is impressively tall! 😲

I remember going to a natural history museum in Australia, as a young boy, (so 40-45 years ago), and there was a model of a giant spider, about the size of a large dog. One of the facts I recall about it, was that it was so large, it needed lungs, which arachnids don't have. I'm guessing it was the product of bad science, or subsequently disproved, as I've never really seen it represented anywhere else. It was truly nightmare inducing, as evidenced by the fact I still can clearly recall the display...

1:12 "The Ostrich really is the Chuck Norris of birds." Said by someone who is not familiar with the Cassowary, clearly.

Personally think the Cassowary is a much more intimidating bird than an Ostrich.😂

5:13 “Snakes are very much the Marmite of the animal kingdom.” That’s gotta be one of Simon’s all-time best quotes

Ostrich may be Chuck Norris, but the cassowary is Bruce Lee

"Your scientist were so preoccupied whether they could that they didn't stop to think if they should." -- Ian Malcolm

Guy next to Andrewsarchus is 10 ft tall

"well over 6 feet tall at the shoulder" *Shows a human for scale indicating maybe 4 foot height at shoulder*

I love the Whistler-verse but these science ones often push my pedantry into a crisis. 1) Smilodon was NOT more closely related to lion than a tiger. The reason it’s correct to say ‘cat’ and not ‘tiger’ is because it was part of the Felidae family, but was not part of the Panthera ‘big cat’ family to which both tigers and lions belong (and are just about closely enough related to be able to partially breed) and nor the family to which small cats, Felinae (everything from your domestic moggie up to Cheetahs and their closest relatives pumas / cougars / mountain ‘lions’). These sabre toothed cats specifically sat just outside these two groups within the Machairodontinae. Its mighty teeth were also likely weak point meaning they were probably not used as forcefully as a lion’s canines to asphyxiate prey but perhaps for inflicting fatal blood loss upon a victim already subdued by those mighty paws 2) Although fragmentary at best, there are more remains than a single Andrewsarchus skull exist, and in fact more than one species within the genus. I believe the latest indication is that it would count Hippos amongst its most closely related extant families, it appears to be equally as closely related to all cetaceans (whales and dolphins), and more closely related to the extinct Entelodont ‘hell pigs’ (which were not pigs…). The interesting thing about these is that they were most likely hoofed creatures which has led some to quip they were sheep in wolves clothing. 3) I don’t believe there is a consensus that the Phorusrhacidae had poor sense of smell, I’ve seen the statement repeated on some websites but the opposite reported in papers. The size estimates are realistic because there are many other species that have been more completely recovered. As these truly are the descendants of the terrestrial theropod dinosaurs, what I find amazing about these bird is that they picked up where their non-avian family left off after the Cretaceous extinction. They also survived until amazing recently, and far from being simply wiped out by ‘superior’ mammal predators, they were one of the few creatures to colonise North America when the two Americas joined rather than the majority of travel in the other direction. As for their only living relatives, the phorusrhacids are not the ancestors to the extant seriema but rather relatives. The phorusrhacids diverged from the Cariama and their last common ancestor necessarily predates the earliest terror birds at 53 million years ago.

Hello everybody, have a wonderful day!

Sabertooth CAT wasn't a tiger. It's not even a member of the panthera genus. It's a member of the felidae genus. Meaning the sabertooth is more closely related to your pet cat than a tiger.

We don't have ostriches in Australia hahahaha Emu and Cassowary yeah I'm pretty high rn but I've never seen a ostrich walking around out in the bush 😅 😂😂

0:35 - Chapter 1 - The smilodon 1:50 - Chapter 2 - Andrewsarchus 3:25 - Chapter 3 - The short faced bear 5:10 - Chapter 4 - Titanoboa 7:10 - Chapter 5 - The wooly mammoth 9:50 - Chapter 6 - Terror birds

Dude in the comparison shoot must be like 12 ft tall if it was 6 ft at the shoulder

"...the Chuck Norris of birds." made me spit out my drink. I love the unexpected humor of the writers and Simon's delivery.

9:57 Pretty sure that name has got nothing to do with Gorillas and more with Guillermo. 😂

Man I love this channel, but this video is mess with all the errors :|

You could quite reasonably argue that when it comes to animals, the world is a fairly fascinating place.

Honestly, this doesn’t even even sound like Simon. It really sounds like an AI spoof channel.

I already consider the ostrich a fluffy Easter chick when compared to the Cassowary.

The ostrich isn't even a native Australian species. Wack comparison.

lol why is Simon talking about ostriches being from Australia when they are native to Africa? Is he thinking of the Cassowary which is the most deadly bird and from Australia? Feel like this vid kinda misses a few factoids since ostriches are pretty unimpressive and would flee when provoked.

My most sincere apologies for the ostrich mixup. Been doing this for too long for such amateur mistakes. Will do better :-)

The crazy thing is, most reptiles (especially snakes) don't really stop growing until death. Titaniboa could in theory, get even larger.

I think you might meen cassowary there mate 👍👍

Just finished your video, great video by the way.... Question: Are you going to make a part 2 of this? After all you failed to mention something the king from Australia that we were glad that it's now extinct. It's a species monitor lizard, except this one is approximately the same length as a school bus, and can weigh close to as much!!

Every single Aussie just face-palmed at the 10min mark... Enjoyable video though 😂 Keep up the fun content Simon 👍👍

10:50 “3M (10M)”

Here early, but thankfully not early enough for these beasts to still be around 🙌

i absolutely love this channel

Simon, we are distinctly SHORT of ostriches here in Australia - only to be found in zoos! Methinks you're either thinking of the emu, which does have a mean kick if it could be bothered or, much more likely, the CASSOWARY, which definitely could disembowel you if you approached it the wrong way! For a fact man you can occasionally get things rather embarrassingly wrong!

Thanks for sharing 😀👍

"Just how big were they? . . . Well, they were pretty big." Thank you, Simon.

I would rather see the dodo bird brought back from extinction than the mammoth. I would also like to see the Moa bird than the Mammoth. Go team chocobo!

When are you doing a video about the giant? The one used to scale the Andrewsarchus. Can't wait to see that one!!!

You are all over the board with the subjects of your channels but I'm here for it.👍

Hello

You would sadly have better luck with a cassowary

Simon talking about ostriches like their from Australia is just dissapointing Come on fact boi!😂😂😂😂😂

1:44 If that artistic impression it's accurate,the Smilodon likely ate smaller prey and used their teeth as rakes instead of harpoons, as they can't open their mouths wide enough to bite large prey. Some food for thought. 😜

DAMN NATURE! You scary!

Simon come visit South Africa to come see Ostriches!

I refuse to believe Sun Bears are actual bears and not just a man in a bear costume

If you're talking about Emus, they're not particularly killy, but if you actually meant Cassowaries, then yeah, they'll kill you as soon as look at you! An Army friend of mine was chased up a tree by one while on training in the Daintree Forrest. This is in reference to the Ostrich section of the video...

Even if they bring mammoths back, it won’t be an actual mammoth because it will learn from elephants, so it will just be a hairy elephant

The Tasmanian Tiger is still alive today in a remote part of Papua New Guinea. An area cut off from humans high in the mountainous region.

Anyone else out there just assume that the paleontologist named Andrew Sarchus named the animal after himself?

Well a snake names vasuki indicus is also been found which is larger than titanaboa

Sorry to burst your bubble, but Ostriches come from Africa, Australia also has two flightless birds, the Emu (much like an Ostrich but a bit smaller, it can be dangerous), and the Cassowary which is smaller again but much more dangerous, it has been known to disembowel people with its long claws on it's feet.

There are no claws that can rip thru steel not even ones made out of a harder material the problem with cutting steel is the fact the metal is really hard to move out of the way.

damn RIP Andy Sarkis, didn't realize he went extinct

Just goes to show, no matter how much you get right, people will always focus on your wrongs.

Andrew Sarchus sounds like an accountant with a pocket protector.

So close to a million subs!!!!

Marmite! Thanks to a Brain Blaze episode I recently saw I know what this is and why it’s a funny reference!

Smiley Don would make a nice pet.

For bears, the Kodiak is also worth mentioning.

Vasuki indicus you missed it

So... kelenken guillermoi was a massive meat eating toucan from a long lost paleolithic hell, *CHECK*.

Best ancient animal video yet. Thank you for pointing out that all we have is fossils and in most cases very few. Also pointing out that all the statements made about the animals are at best educated guesses and least just normal guesses. Oh and btw we have dinosaur DNA as well since they have found living tissue of dinosaurs making them about then 5000-10000years old since science says that that tissue has a half life of 5000 years and that is observable science. I say if we bring back the mammoth and dodo we might as well go full Jurassic Park and bring back the dinosaurs. If your gonna play god don’t hold back go all in on it.

Given how at least some Terrorbirds had forward pointing stubby wings with two claws on each they were basically Sauropod 2.0. A literal Raptor, if you will.

Types of tigers still alive today, get *_much_* bigger than lions. Male Siberian tigers get nearly _double._ Even female Siberians ovelap with smaller (adult) male lions.

With a couple of recent lists like this one, maybe we could get a list of extinct animals from within the last 500 years or so?

I'm a bit surprised that they didn't put sarcosuchus imperator on the list.

Carnivorous Hippopotamus is a horrifying combination.

Oh really? I thought Andrewsarchus played the waiter in Fawlty Towers.

Monstrous killing machine, cuts to cubs playing 😄

"1,135 kg (1.25 tons)" That's not how the metric system works 🤔

One of my favorite extinct animals, is the Platybelodon. An ancient elephant, with a hippo-sized mouth, inside it’s trunk. Google it, and watch your jaw hit the floor.

That lion things claws look insane

A 50ft long 2000lbs snake, too big to go through a door, is absolutely terrifying. Something tells me it ate things much bigger than fish.... Thats nightmare fuel of the highest octane

Love all these videos on all the channels. If they re-engineer the wholly mammoth they won’t be mammoths. They’ll be more akin to the Borg than to the OG wholly mammoth after all the genome hacking and slashing. Still cool though.

This is the closest I will get to a Simon animal channel

Titanoboa is fascinating 6:58 Modern day Burmese Pythons eat American Alligators in the Everglades... So yeah, it definitely would have been eating crocodilians

I've never heard 'turtles" pronounced so majestically!

Everyone who has played Ark: Survival knows these species, but even in the game, it can be hard to imagine just how big they were.

Last i was this early, titanoboa was still around.

Was a bit sad the Monty Pythonus didn't make the list, but then it got assigned to an existing genus, so the monty part of it's name went away

Kill-stealing is easier than predation because predators don't want to get injured fighting over a single meal (an injury that is not immediately fatal can still be fatal in the long run), but prey will fight to the death because there's nothing else for it.

"Some experts claim could cut through steel", are these experts on steel? What kind of steel? This statement is too broad and isn't super impressive given that mild steel that's thin isn't hard to cut through.

Entire scientific community: "Global temperatures are going to dramatically rise over the next 100 years." Tech bro geneticists: "What if we make a mammoth?"

The Andrewsarchus skull looks like a Cubone from Pokemon!

Fun fact: last mammoths were alive while Pyramids were built

Simon, you should have included Arctodus simus which was the Giant Short faced bear that only died out toward the end of the last glaciation about 12,800 years ago. Some of these were believed to have been the largest land based carnivores to exist since the Dinosaurs perished in the mishap of navigation 65 million years ago !! There are some who believe they may still be alive in the remotest parts of Alaska and Siberia - although no conclusive evidence has been found - its unlikely, but not impossible. The Yeti has been shown, at least from samples obtained from locals and monastaries, so be various species of known, but rare bears - which have rarely been seen or photographed

Oh dear, Emus are native to Australia, not Ostriches.

I'm glad the big snake isn't around.

All the ivory hunters just rubbed their hands together and went mwahahahaha!

Animals!

The bird graphic has an error, it says it was "3 m (10 m)" should be "3 m (10 ft)" 10:50

Andrewsarchus being well over 6 feet tall at the shoulder, displayed with bent forelimbs, with the silhouette of a 10 feet tall person for scale.

On the second animal, why show a human being taller than it when saying and showing that it was taller than 6 ft at the shoulder unless the image of human was 7 or 8 ft tall 😂😂😂😂

Those are Emus...

We could do with out these . Bringing the Mammoth back will be living torture since what was thier living space is ruined or gone .

What if we bring back a T-Rex and it’s just as cuddly as your average dog?

He definitely meant cassowary
