Description
They are truly massive, but compared to large theropods even the largest of them still pale pathetically. Hence I excluded theropods.In order from human to the right.
Prestosuchus chiniquensis
INACCURATE IN CHART: actual skull length 80 cm instead of 1 m, so should be ~5.6 m long, making it smaller than Fasolasuchus, ´Aliwalia rex´, and Saurosuchus.
From early-middle Triassic South America.
Varanus priscus
Or Megalania. It is easily the largest terrestrial lizard known, at a max length of 5.3-5.5 m. I anticipated it to look more underwhelming, but as it turns out a ~5.4 m long lizard does look bloody huge. At 5.4 m it would have a mass of around half a metric tonne. It shared its habitat with the much smaller marsupial predator Thylacoleo. From pleistocene Australia.
Arctodus simus
Often cited as the largest predatory land mammal, a titel that it shares with Daeodon and Andrewsarchus. Around 750-1000 kg for this specimen. It is also cheating a bit because it wasn´t a full time predator but an omnivore. From the pleistocene North America.
Erythrosuchus africanus
Perhaps it comes as a surprise, but Erythrosuchus is bloody massive for the largest specimens, ~5.4 m long along the centra and ~1.3 m tall.
It is equal in length to V.priscus but enormously more bulky, likely allowing it to reach 1+ metric tonne. From the early Triassic Karoo beds.
Anteosaurus magnificus
The largest terrestrial synapsid predator known, with a tyrannosaur-like skull of 80.5 cm, nearly as long as Andrewsarchus´ skull while being much shorter proportionally. Probably a bit heavier than Arctodus, but unsure how much. It actually converged on tyrannosaurines in a number of ways, including bony bosses on the head and a strong wide skull. From the capitanian middle Permian Karoo beds.
Razanandrongobe sakalavae
A runner up contender for the title, at a nearly equal size to Prestosuchus (6.3 m vs 7m), and claiming the apex predator title in Madagascar (attached to Africa at the time) in the middle Jurassic. Other African theropods from that age (Afrovenator would be ~1.2 t) are probably slightly less massive. 2 t does not seem unlikely as a mass for this crocodyliform.
Daeodon shoshonensis
A large basal whippomorph ungulate, and one of the largest mammalian terrestrial predators. Slightly larger than Andrewsarchus (90cm skull vs 84 cm), which I excluded because the two would be too similar. It is from the Oligocene-Miocene.

Nice! Looking forwards to seeing more charts from you, mate.

Considering how big some mammalian herbivores have grown in the last 66 million years, it's strange that the terrestrial predatory mammals apparently haven't kept up as much as their theropod analogs. At least, I'm not aware of any mammalian predator big and strong enough to prey on fully-grown elephants or rhinos the way a T. rex might prey on large ceratopsians or hadrosaurs. I wonder why that seems to be the case?

I have no idea.
Mammalian land predators were/are diverse, as were their large prey.

theres various constraints about mammalian anatomy that really places limits on how large we can get on land. (our reproduction methods require a lot of energy, our bones tend to be more solid, our respiratory systems isn't as effecient, etc) theres just specific ways about how mammals utilize energy the places caps on body size on land, that dinosaurus aren't held back on

OK, thanks for the explanation!

While the largest theropods dwarf these, these guys are still comparable to most large theropods...,

Andrewsarchus has very little adaptations for eating meat, so it wouldn't have made it on this chart anyway.
👍: 0 ⏩: 2
Not an obligate one, at any rate.

Yes.
Though I also included Arctodus so that is not a problem.

Take a look at the skull of Andrewsarchus: it’s an omnivore at minimum.
We don’t know what it was hunting but it was hunting....something.
👍: 0 ⏩: 1
I did. Those teeth, especially the odd pin-shaped ones, don't look like they'd be good for much in the way of crushing or tearing meat. If anything, Andrewsarchus is more like a modern hippo than an entelodont.
👍: 0 ⏩: 2
Andrewsarchus doesn’t have grinding molars like hippos, though.
👍: 0 ⏩: 0
The molars are in between those of carnivorans and hippos. Looks like pretty much all purpose for processing meat and maybe vegetation.

Wow I didn’t thing the Madagascan croc would be that impressive! How does Barinasuchus compare to these?
👍: 0 ⏩: 1
I was surprised too!
Barinasuchus is not too impressive apparently (I scaled Langstonia to a 94 cm mandible to see and I did not get 5+ m).
but I can include it.
👍: 0 ⏩: 2
I’ve actually heard that Barinasuchus had a deeper, shorter skull than Langstonia, so not sure how reliable scaling it from Langstonia is.
👍: 0 ⏩: 1
It did have a deeper skull. Scaling it is pretty hard in general.
👍: 1 ⏩: 0
Is Langstonia a closer relative chronologically? Because it depends on who we scale from. The skull is still similar or slightly greater in length (shorter lower jaw but that’s only because the back offshoot of the mandible is much shorter than that of modern crocs) and considerably more massive than the largest recorded saltie skull, so that’s something.
👍: 0 ⏩: 1
Langstonia is the best option to scale from, though it is not a perfect fit.
I got a head/body ratio of around 5, giving it a TL of ~4.7 m.
👍: 0 ⏩: 1
So assuming scaling is ok, then its roughly 74% larger than Langstonia? Which isn't small itself of course if its 2.7m long.
And sorry to apply this dreaded sight, but this?: www.prehistoric-wildlife.com/i…
I don't know what mass Langstonia would be given how fragmentary it was, but if Barina has similar proportions, it would be about 5.268 times as massive.
Still would sound pretty impressive even if we assume a proportionally huge head like this.

Interesting, since that Ralph Molnar found that Barinasuchus could measures over 6 meters, although based in Stratiotosuchus - and my Langstonia was more or less based in Baurusuchus...
👍: 1 ⏩: 0
Yeah it is not small in any case.

Very nice! Charts of large non-dinosaur predators are nice!
Also, chuckled at that Arctodus silhouette colored like Winnie the Pooh

Would azhdarchids not count? They obviously weren't only terrestrial, but they hunted terrestrially
👍: 1 ⏩: 2
I was about to comment about that! That said, they might be too tall to fit in the picture.

Yes they would count. I might add one later, maybe.
