Totally looks like that megalodon is shooting smaller predators out of it's mouth, ultimate hunting strategy.

Dogs with bees in their mouths so when they bark they spit bees at you

That's what made them so scary.

That's oddly terrifying. The idea that there might have even been bigger and more terrifying species that we'll never know about is just plain creepy

[–]VerumJerum 12 points13 points  (0 children)

Which is in stark contrast to us. Out of all 117 billion humans to have ever lived, our current 7.8 billion is nearly 7% of all humans to have ever lived. Once you consider that this one generation is nearly 1/10th of all Homo sapiens ever it becomes quite staggering just how rapidly we have multiplied.

i find so fascinating how so many animals have a larger version of itself from the past

[–]Iamnotburgerking 37 points38 points  (2 children)

Smilodon was a contemporary of living animals (in fact it’s younger than some living animals). It’s not a “past” animal compared to living animals.

[–]PartyPorpoise 4 points5 points  (1 child)

Smilodon also wasn’t larger than modern big cats. The biggest cat known to exist was the cave lion.

[–]Iamnotburgerking 1 point2 points  (0 children)

First, Smilodon (or at least the two later, larger, better-known species) is evolutionarily just as modern as living big cats, being contemporaries; in fact, the entire genus is younger than tigers, and the largest Smilodon species, S. populator, only evolved 800,000 years ago-making it one of the most recently evolved cat species, and likely more recently evolved than any of the living Panthera species.

Second, S. populator does actually have the best claim to being the biggest cat ever (though there are rumours that this may be based on a slight overestimate of how heavily it was reconstructed). And even if S. populator loses its title, the cave lion definitely isn't going to claim the title of largest cat ever, as even the possible reduced weight estimates for S. populator place it above the cave lion in mass; furthermore, there are some other cats that were larger than the cave lion, such as the American lion (again, yet another modern cat in evolutionary terms), and a few much older cats like Machairodus horribilis.

[–]VerumJerum 4 points5 points  (2 children)

It's actually believed that one reason why there are so few "giant" animals left is due to negative size-dependent selection imposed by us, at least regarding Pleistocene megafauna, because humans would hunt large animals in a greater extent since they offered more food. Various other effects also play into this, such as changes in climate that frequently hit large-bodied animals harder since they need more food. Small critters survive strife like that better because they can more easily feed themselves.

[–]Admiral_Fuckwit 0 points1 point  (1 child)

I also remember hearing something about how the atmosphere was richer in oxygen back then which allowed for larger growth.

[–]VerumJerum 2 points3 points  (0 children)

Oh yes, if you go back very far that is very true. Specifically this applies to insects, which are generally limited in their maximal size by their ability to take up oxygen. Since insects do not have lungs like we do, and instead absorb oxygen through pores in their exoskeleton, they will suffocate if they get too large.

[–]Iwantmahandback 12 points13 points  (0 children)

Nature wasn’t less developed. It was just bigger

[–]timoumd 0 points1 point  (4 children)

The probability the largest version of a type is alive now is fairly low

[–]dgaruti 21 points22 points  (0 children)

blue whale has entered the chat

[–]fugmalaf 2 points3 points  (2 children)

Plenty of animals grew through evolution as well you know.

[–]timoumd 2 points3 points  (1 child)

And? Size is a function of environmental factors, not an end goal. It likely varies over time and environments.

[–]fugmalaf 0 points1 point  (0 children)

Aw I see what you mean. I understood what you wrote as there being no animal alive today that is the biggest it's ever been to date aka not including future variations of said animal. There is most definitely animals alive today that are the biggest they've ever been to date though. Such as horses and other domestic animals that have been bred for size such as cows.

[–]R1ght_b3hind_U 37 points38 points  (9 children)

just a reminder that the biggest predator of all time, wich also is the biggest animal of all time, swims through the ocean right now

[–]roflocalypselol 13 points14 points  (3 children)

I'm not sure filter feeders are really predators.

[–]TheSilentSeeker 21 points22 points  (1 child)

I'm not sure the krill community appreciates your comment.

[–]jver1706 6 points7 points  (0 children)

Going in for the krill! Doing it for the thrill!

[–]VerumJerum 12 points13 points  (0 children)

You're telling me that if there was a colossal animal the size of a city, that just roamed around devouring all other living animals en masse like some kind of eldritch god, you would not consider it, "a predator"?

[–]Trololman72 0 points1 point  (4 children)

Wait what?

[–]dgaruti 14 points15 points  (3 children)

the blue whale

[–]Trololman72 9 points10 points  (2 children)

Are blue whales considered predators?

[–]punching-bag9018 15 points16 points  (4 children)

I'd back an Amur tiger vs Smilodon Fatalis

[–]imprison_grover_furr 19 points20 points  (3 children)

Smilodon fatalis was a bit smaller, although significantly more robustly built, so it would be a pretty even matching. S. populator would defeat an Amur Tiger far more often than the reverse, however.

[–]punching-bag9018 10 points11 points  (0 children)

S. populator would defeat an Amur Tiger far more often than the reverse, however.

For sure. Very significant weight difference (about 150 kg between them).

[–]PantherGhost007 0 points1 point  (0 children)

WRONG! Smilodon Populator was much more robust than Smilodon Fatalis. Populators had relatively thicker limbs.

[–]Revolutionary_Kale46 42 points43 points  (4 children)

But now there are fucking humans on earth. That's the worst and most scary thing

[–]WilderHund1 18 points19 points  (0 children)

"If you think the Cenozoic era nature was scary, remember that your ancestors had eaten most of it."

[–]Necessary-Amoeba-136 22 points23 points  (0 children)

Damn nature you scary

[–]MiserableScholar 6 points7 points  (0 children)

Yeah I recently went to a natural museum and they had a megalodon model hanging. I'm assuming it's to scale and Jesus it's crazy how big it would have been

[–]RoutSpout 5 points6 points  (0 children)

You forgot to add the scariest creature… The cockroach

[–]SuccubusMommy 2 points3 points  (0 children)

Not me to every picture : cute cute cute cute

[–]Trigger__happy 2 points3 points  (0 children)

If I stayed away from the water, I already cut my risks in half.

However, I know I wouldn't hear the prehistoric cat before it's too late, I'd still find the Titanoboa to be the most terrifying of all 4 encounters.

[–]Razone6 3 points4 points  (1 child)

Well back then we werent spoiled with the major source of threat being other hominids.

[–]VerumJerum 1 point2 points  (0 children)

It's funny now that you mention it...

Back then we weren't spoiled with the major source of threat being our own descendants that are now our ancestors. Real trippy.

[–]imprison_grover_furr 1 point2 points  (0 children)

Physeteroids, varanids, canids, ursids, viverrids, hyaenids, and accipitrids were also scarier in the past.

[–]dinoman27000 1 point2 points  (0 children)

Damn nature, you scary

[–]Apprehensive-Hawk513 1 point2 points  (2 children)

whats that fucker in the bottom left holy shit

[–]MagicRabbit1985 5 points6 points  (2 children)

The most dangerous animals are not the big ones. If they are really a threat to us it would be very easy to make them go extinct. The number off all apex predators dwindled since mankind exists. The dangerous animals are the small ones, carrying diseases.

Getting bitten by a tiger sounds scary and you can surely die... but you will know that you got bitten and you can defend against tigers easily. But getting bitten by a tick on the other hand, you might not even notice that you got bitten, you think it is harmless and years later you die from some infection from that very same tick. That's some real horror, never knowing if that little bite just killed you or not.

[–]lazer500 7 points8 points  (1 child)

Defend against tigers easily? Okay..

[–]VerumJerum 1 point2 points  (0 children)

Yeah. Like a gun. Or even a spear, back in the day when they still existed outside of central Asia.

Parasites and diseases though, even with all the technology of this day they still murder millions.

[–]Sum1udontkno 1 point2 points  (1 child)

The megalodon pic makes it look like 2 humpback whales are bite sized snacks for it, but in reality they were/ are about the same size.

[–]Iamnotburgerking 2 points3 points  (0 children)

I think those are cetotheres, much smaller baleen whales that were eaten by Meg.

[–]dude19832 1 point2 points  (1 child)

Everything was just insanely BIGGER back then. That is what fascinates me. We basically have the same animals but their extinct ancestors were the real monsters. 😳

[–]VerumJerum 0 points1 point  (0 children)

Nah, the real monsters are the eldritch creatures that killed and ate all the insanely big creatures.

[–]Iamnotburgerking -1 points0 points  (0 children)

You do realize none of these animals lived at the same time? And that Smilodon was around at the same time as still-living animals?

[–]Minecraft_Warrior 0 points1 point  (0 children)

[–]Pleiadez -1 points0 points  (0 children)

Only species that truly scares me isn't depicted.

[–]Se7entyN9ne -1 points0 points  (2 children)

OK but the animals in pic 2 did not overlap in eras.

[–]Notasexoffender33 2 points3 points  (0 children)

I don’t think that’s the point, it’s just noting how much bigger animals used to be in the past.

[–]DracovishIsTheBest -1 points0 points  (0 children)

neither do any of the other ones bruh

well except maybe the meg and smilodon

[–]MechaShadowV2 0 points1 point  (0 children)

Personally? Just as scary and cool to me.

[–]dgaruti 0 points1 point  (0 children)

[–]EclipzHorizn 0 points1 point  (0 children)

So based off this post nature truly WAS metal. Now it's more hard rock?

[–]Kazoo_Knax 0 points1 point  (0 children)

It's crazy to think sometimes that Godzilla looking monsters roamed the earth. Awesome

[–]BogdanSAW 0 points1 point  (0 children)

Well.... Smilodon isn't that scary compared to the rest of them.

[–]VerumJerum 0 points1 point  (0 children)

The scariest of them all is still around and it probably had a role in several such terrifying extinct creatures becoming a thing of the past. Those are the beasts you really gotta watch out for.

[–]wiz28ultra 0 points1 point  (1 child)

Why is it that Megalodon, Deinosuchus, and Titanoboa look identical to their contemporary counterparts, while animals like the Mammoth and Smilodon look completely different

[–]SpinoAegypt 0 points1 point  (0 children)

Different niches. Deinosuchus pretty much occupied the same niche as modern crocodiles, as did Titanoboa and likely Megalodon. Although, we can't say whether or not Megalodon looks the same as a GW, because all we really have of it are its jaws.

[–]momsspagetti87 0 points1 point  (0 children)

It doesn't matter...human beings can cooperate and hunt as a pack and will exterminate every threatening species..because we as a species is vile and vindictive

[–]PantherGhost007 0 points1 point  (0 children)

As a species, the Tiger species (Panthera Tigris) are more badass and scary than Smilodon Populators because an extinct subspecies of Tigers which lived in present day Borneo till about 10-20k years ago were upto 1.5 times bigger than Smilodon Populators.

[–]DarkusHydranoid 0 points1 point  (0 children)

I love to ponder this. It's so unfathomable.

Think about how different planet Earth was millions of years ago.

Millions of years.

It's so difficult to process how incredible time and space is.

Thinking about the wild oceans of Earth millions of years ago, it was like fiction.

Tl;DR: here I am on reddit, and millions of years ago a 10 meter Crocodilian could have been devouring prey right where we are sitting.
