This might be the first non-bogus media representation of Gigantopithecus and I'm really excited for it.

Not a tug of war but I suppose it's two red/brown/orange-ish rexes contending a piece of a carcass? By Davide Bonadonna

The insane thing about this attack is that the crocodile is making a charge at the fully exposed back of the elephant. There's no mistake, as it often seems to happen with trunks/genitals.

Contrarily to popular belief, big crocs aren't particularly scared of hippos, nor seriously risk "being snapped in half", a phrase few documentaries skip on when talking about these confrontations.

I find particularly frustrating how Deinogalerix is mostly dismissed as an insectivore occasionally preying on small vertebrates, because that's what its closest extant relatives (moonrats and hedgehogs) already do, and they don't have a massively oversized set of jaws.

One of my favourite insular ecosystems. Full of underrated oddities. Deinogalerix is a true weirdo: a moonrat the size of a housecat, but jaws 1/3rd of it whole length.

Interestingly, emu chicks have stripes even on the skin! They're pink-red and grey-blue underneath the feathers, like ostriches. I wonder if the stripes are maintained throughout adulthood, as at this stage the pattern is already fading on the feathered chicks.

IF it's somehow not a forgery, it's a very weird case of scavenging gone wrong, because the in vivo predation is simply impossible considering how they interlock at the level of the bones, where there would be soft tissue:

Deinosuchus seems to be the largest overall, but of course that's very sample-dependant (visualization by TA Holmes/Fadeno)

Snakes usually feed on live prey and have to be "tricked" in captivity for prekilled ones. Some snakes though occasionally eat carrion , like these garter snakes, and can be habituated even to plate feeding!

I remember when I first saw this one, after having my mind go wild with the pics of the arms alone for so long, and thinking "nah that doesn't look like a big animal". It was a crude first impression but kinda on the right path lol

For me, it's this mount. It really ingrained in my brain Torvosaurus as unique.
