Eurypterids, AKA sea scorpions, could grow to astounding sizes, making them the biggest arthropods known to have existed. Considering they’re a sister group to arachnids, I understand why some people might be terrified at the sight of this.
Contrary to their name, they weren’t scorpions, and not all of them lived exclusively in the sea.

Getting late over here, so one more post for tonight. Here’s just a friendly reminder that we live in a world where a dinosaur was given the name “Thanos”. Yes, that is its actual real scientific name. And it’s only known from a single vertebra.
It belonged to a family called the abelisaurids, which had very, very short arms that were more or less completely useless. So, unfortunately, this Thanos couldn’t wear the Infinity Gauntlet, let alone even snap his fingers

it kinda looks like a roadrunner

I don't know if anybody in the thread mentioned is but Dunkleosteus had one of the most badass aesthetics of Devonian period.

Time to ruin the fun:
I actually just watched some stuff about ol' dunkley here the other day. Apparently it most likely had lips.

I really like Yutyrannus. It’s the largest dinosaur known to have feathers, and was a distant relative of T. rex. Although...there were definitely even larger feathered theropods than it!
This is my interpretation of Deinocheirus from a few months ago. For over half a decade, all that was known of this dinosaur were two massive arms. It was only in 2014 that we could aggregate enough material to build a better picture of what it might have looked like. It was freaking massive...around eleven metres long, I think. What’s interesting is that some of its tailbones were fused together, as seen in modern birds, which could mean that it had feathers. I was a little conservative with the feather covering here though, as its large size meant that it could regulate its heat without the need for more complex integumentary structures.

Throwback to that time nature tried to make anthro horses but got stuck at the gorilla stage

It was the definitive Big Chungus

Andrewsarchus, the largest predatory land mammal by volume (One species of bear was heavier).
Despite it's appearance, it's closest living relatives are Hippos, not Caniform Carnivores

The Haast's Eagle was a megaborb driven to extinction around 1400 when the Maori killed off their main prey, the gigaborb Moa.

I've read about these. From what I remember they clearly weren't too pleased about it any kept trying to eat the Maori instead

I wonder what gave them larger volume if the bear species was heavier? Did they have huge lungs or something?

Aight here's a few I've found recently
Aegirocassis, the original Big Chungus
Jaekelopterus, the largest arthropod ever, and the actual worst thing ever
Carnufex, a bipedal crocodile
Makaracetus, a weird whale-hippo-elephant thing
Helicoprion, a shark with a buzzsaw for a face
The Terror Hyena. Which kinda speaks for itself.
Proborhyaena - slightly smaller than the other yeen, but it gets a pouch, and stronger muscles
Nuralagus, an actual Big Chungus
Terror Beasts, which were funky looking giant elephants
Bataller's Panda - like a red panda, except it'll try and eat you

Necro-reply I guess but I actually ended up making an OC of one of theseThylacoleo, the "marsupial lion" was not actually related to lions, but but sort of looks as if it were, if you ignore those really weird teeth. They were similar to thylacines, in terms of being predatory marsupials, but I have no idea if they were closely related. Thylacoleo went extinct long before thylacine did, but still existed at the same time as humans. Climate change is the primary reason believed to have caused their extinction.

True, but how many did nature create that we just haven't found yet? Natue is always trying new stuff and seeing what works and what doesn't.

In fairness, with Arthropods especially, sometimes a new "species" is so incredibly similar to it's relatives that it can only be distinguished by genetic sequencing.
Take the 1300 different species of Mining Bee as an example.

Very true...but those differences are all that matters in the long run, as small "errors" or "advantages" eventually mutate into either better versions, or die out/become dormant traits. Nature is amazingly fascinating when you get to the genetic levels, ain't it?! <grin>
