Awesome Megafauna Skulls!

My last weird and awesome skull post was really popular, so I decided to do one about something else I’m excessively interested in: Megafauna! This isn’t at all a comprehensive list of the coolest ones, not by a long shot, so you should definitely look up some of the BBC docs on Youtube or google ones from your continent!

The cave bear! (N. America)

‘Hell Pigs’ (N. America) Actually entelodonts, unrelated to pigs at all and more closely tied to hippos and cetaceans! Dat sagittal crest amirite

The Stag Moose  @allosauroid brought to my attention that this is the skull of the Irish elk, Megaloceros, not a stag moose! (Eurasia) Which stood 6 foot at the shoulder/withers

Platybelodon (widespread) Google artist renditions of these guys, you won’t be disappointed

Barbourofelis! (N. America) Like a smaller smilodon, with much cooler teeth. Look at those incisors!

Megatherium (S. America) Primitive sloths the size of elephants!

Titanus Walleri (N. America) Other continents had equally large if not larger ‘terror birds’

Paraceratherium (Eurasia) One of the largest terrestrial mammals we’ve ever discovered. It was actually a species of hornless rhino! Google artist recs of these guys, too

Diprotodon (Australia) The largest known marsupial, which was the size of a hippopotamus and stood 6 feet tall

I saved Glyptodon (S. America) for last, because these things have some of the weirdest skulls I’ve ever seen. They were technically armadillos, but reached the size of a Volkswagen Beetle!

Entelodonts are usually portrayed as pretty fierce and violent, but I’m sure they had some tender moments as well. (I love doing research for my drawings but I found no info about how Entelodonts care for offspring. Since they’re so closely related to hippos, which are pretty doting mothers, I’d like to think Entelodonts are similar). 

anonymous asked:

would their side skull protuberances be visible? i am sorry for all the Entelodont questions but i need that information for a personal project

It’s okay, that’s what I’m here for! I guess it depends on your personal preferences a bit - obviously they’re not going to be COMPLETELY hidden, but how just visible they are is sort of up to you.


The result of my Pokemon Reimagined stream! Got to draw three neat Pokemon and share the process with the watchers. It was so much fun and if you missed it, no worries, I plan to make another one at some point!

Here we have Mamoswine, Sigilyph and Meowstic (f) - obviously not in scale but I wanted to show them off together - with the sketches I made in the planning process. I didn’t sketch quite as much as I maybe should but that’s something I can pay more attention in the future to improve.

Mamoswine was based on a mammoth, wild boar and a little bit on entelodont.

Sigilyph was mainly based on a hummingbird and some other birds, one being a hawk with amazing long feathers on its wings whose name I can’t remember. And Meowstic is mainly based on lemurs, aye aye and with a hint of cat and bat.

I’ll most most likely end up finishing all three - Meowstic and Mamoswine for sure  - so look forward to that!

Thanks to everyone who stopped by! I hope you enjoyed it!

Daeodon, from the late Oligocene and early Miocene of North America (~29-19 mya). About 1.8m tall at the shoulders (6′), it was one of the last and largest of the entelodonts, a group of omnivorous even-toed ungulates with long bone-crushing jaws.

Although often called “hell pigs” or “terminator pigs”, entelodonts weren’t actually pigs at all – instead they were much more closely related to hippos, whales, and Andrewsarchus.


Doodle dump! It’s been awhile since I’ve made one of these.

(Row 1, left) For Inktober, I’ve been doing a little project called Daily Dino & Prehistoric Pals, which you can find on my art blog at @avigorito-art. I naturally decided to be a dork and make some Cenozoic GUG, with Ganon as an Entelodont, Link as a dire wolf, and Nabooru as a Smilodon.
(Row 1, right) Some Nabgsan and Midlink furries. I just wanted an excuse to draw Midna as a panther, I’m sorry.
(Row 2, left) Zelda dress design. I plan to explore her design more, but the sketch turned out decent.
(Row 2, middle) some Ghirahim
(Row 2. right) Although it doesn’t happen in the story, Roy and I are super open to the concept of Link and Vridi as a ship.
(Row 3) Nabsgan nose smooshin’
(Row 4) Since they’re all bratty kids right now in the comic (Vridi is an exception though), I just wanted to draw them chummin’ around.
(Row 5) GUG!Ganon hanging with @leafyns’ Ganon!

These Animals Were Just As Awesome and Fascinating As Dinosaurs

Fossil mammals have been in the shadows for too long.

by Brian Switek

If you’re in New York City and need a break from the swarms crowding the sidewalks, I know where you can go. The Milstein Hall of Advanced Mammals in the American Museum of Natural History is almost always quiet.

You may bump into the occasional student trying to fill out a science class scavenger hunt or a confused family wondering where the dinosaurs are, but the hall is usually as hushed as a tomb. That’s fitting for a room boasting skeletons of fossil beasts shoved into almost every corner, but it’s also a shame.

I’ve seen the same at other major museums: the Field Museum in Chicago; the Carnegie in Pittsburgh; the Peabody in New Haven, Connecticut; the Los Angeles Museum of Natural History; the Royal Ontario Museum in Toronto; and more. Hordes of children and adult visitors pack the dinosaur halls, but the fossil mammals stand in the shadows—dominated by the reptiles in death just as they were in life.

After a mass extinction released mammals from the tyranny of the dinosaurian reign, they became even more strange and spectacular. But even these species have been obscured by the popularity of the scaly and fuzzy reptiles. Some visitors, assuming that any skeleton in a museum must be from the Mesozoic, even go so far as to insult giant sloths, multitoed horses, and enormous elephants by calling them dinosaurs…

Something that really upsets me about palaeoartists who draw extinct mammals in particular is the rampant shrinkwrapping.

Compare a hippo skull and hippo head:

Or a pig:

And now look at how extinct mammals are depicted. Like entelodonts:

Or uintatheres:

It just……really doesn’t follow what we know about mammals, at all. I’d wager both entelodonts and uintatheres had a LOT of soft tissue on their heads completely obscuring the shape of their skulls, and so did a lot of other extinct mammals.

Another NHMLA specimen: Entelodont archaeotherium. 

Entelodonts, sometimes facetiously termed hell pigs or terminator pigs are an extinct family of pig-like omnivores endemic to forests and plains of North America, Europe, and Asia from the late Eocene to early Miocene epochs.

Also known as “hell-pigs”, though they were related more closely to hippos and whales than to pigs, Entelodonts were huge pig-like animals that lived during the Eocene-Miocene and appeared to have been one of the largest and most formidable land predators and/or scavengers alive at the time. They were omnivores, mostly, but judging by the massive design of their jaws it’s fairly obvious that they would have tackled large prey as well as plant matter. It is thought that they would have preyed on animals as large as Eporeodon, which grew to the size of a cow. And apparently some Entelodonts, such as Archaeotherium, have been discovered to have hoarded or cached their food- with the discovery of a cache of several early camels. They were so successful that they existed on this planet for approximately 21 million years.

The largest was horse-sized Daeodon, which could have weighed up to 930lbs and stood at around 6.9 feet tall.
