Please note I published this under a noncommercial Creative Commons license. Feel free to share if you find it useful or interesting! This is a chart on the possible colours of European wild horses or tarpans (Equus ferus ferus) - a surprisingly varied population, as shown by ancient dna and cave art. These animals only went extinct around year 1900. Depicted is a selection of possible combinations of the alleles known to have been present in wild tarpans. According to the data set of Pruvost et al. (2011), the most common colours were bay dun, grullo, and spotted bay dun - marked with blue circles in this chart. All these seem to be also depicted in European cave art. Other combinations would have necessarily occurred from time to time, when horses of different colours mated. The Lp allele, producing leopard spotting, is affected by a large number of modifiers, none of which have been tested on ancient horses. I depicted a variety of possible outcomes of it, but it’s impossible right now to be sure which spotting patterns were really present. The letters underneath each horse refer to their alleles. These three were polymorphic in the tarpan population: Agouti locus A - dominant allele causing brown coat a/a - recessive allele causing black coat Extension locus E - dominant allele enabling black in coat and mane e/e - recessive allele preventing black coat and mane (result being a chestnut horse) Leopard / varnish roan locus lp/lp - no leopard complex, no spots Lp/lp - leopard complex, spotted LP/LP - leopard complex, mostly white. There is a night vision defect associated with homozygous animals, probably making them vulnerable to predators. I had to assume these last two, since there is no genetic test for them at the moment: D - dun, a diluting factor present in wild horses and asses. Causes lighter coat colour and primitive markings (two-coloured mane, stripes etc.) PATN1 - patterning factor, causes leopard spots with LP Reference: www.pnas.org/content/108/46/18…

Are you saying there isn’t a test for Dun and Pattern1? Because there is; Dun, nd1 and nd2 are all testable as is Patn1. LP on its own only causes characteristics and varnish

Ampelomeryx ginsburgi, a palaeomerycid ungulate from the Early Miocene of France (~17 mya). About the size of a deer, around 1m tall at the shoulder (3′3″), it was a distant relative of modern giraffids.

Males sported three distinctive ossicone-like ‘horns’ – two over their eyes and a third forked one at the back of the skull – and protruding tusks like some modern deer, which probably served a similar purpose in fights against each other.

Performing a CT scan on a horse is a laborious process that takes a team of nearly a dozen technicians and veterinarians. It involves forklifts and cranes, and the skilled techniques of veterinary technicians who have mastered this task after years of repetition. Watch the procedure be performed at the UC Davis veterinary hospital…

Bella, a 16-year-old American Quarter Horse mare, has historically suffered from chronic hind limb issues. She was previously diagnosed with bilateral osteoarthritis of the lower tarsal joints (hock), but intra-articular medication had failed to significantly improve her lameness on the right hind. Bella had been ridden by two small children for the past three years and is an integral part of their family. Due to the severity of this lameness, however, she could no longer be ridden. Committed to improving Bella’s condition, her family brought her to the UC Davis veterinary hospital.
Upon being presented to the Equine Surgery and Lameness Service, Dr. Larry Galuppo and his team performed an exhaustive lameness exam with diagnostic analgesia and used a computerized lameness locator system to confirm that the area causing her pain and lameness was the right hock. A possible surgical intervention consisting of fusing some of Bella’s tarsal joints was considered, but additional information to determine the exact location of the lesion and plan for the surgery was needed.

Macrauchenia was a long-necked and long-limbed, three-toed South American ungulate mammal, typifying the order Litopterna. Macrauchenia had a somewhat camel-like body, with sturdy legs, a long neck and a relatively small head. Its feet, however, more closely resembled those of a modern rhinoceros, and had three hoofs each. 

One striking characteristic of Macrauchenia is that, unlike most other mammals, the openings for nostrils on its skull were atop the head, leading some early scientists to believe that, much like a whale, it used these nostrils as a form of snorkel. Soon after, this theory was rejected. An alternative theory is that the animal possessed a trunk, perhaps to keep dust out of the nostrils. Macrauchenia’s trunk may be comparable to that of the modern Saiga antelope.

Unsolved Paleo Mysteries Month #14 – The Mystery Mega Mammal

During a 1923 expedition by the American Museum of Natural History to Inner Mongolia, China, a huge mammal skull was discovered dating to the Middle Eocene (~48-37 mya). About 83cm long (2′8″), with small low-set eyes, it was named Andrewsarchus mongoliensis in honor of expedition member Roy Chapman Andrews.

Almost a century later that one skull is still all we have. And despite this animal’s popularity among paleo-fans, we actually know very little about it.

It was originally classified as a mesonychian, leading to the many many depictions of it as a sort of “big bad wolf”. But more recent studies have placed it in the even-toed ungulates instead, with some suggestions that it might be most closely related to entelodonts, hippos, and whales.

Although it was certainly a big animal, it may not have been the giant “super predator” it’s often depicted as – its teeth aren’t particularly specialized and resemble those of entelodonts, suggesting it may have been more of an opportunistic omnivore than a dedicated carnivore.

Without more material we just don’t know for certain. So, frustratingly, the rest of Andrewsarchus’ body remains a mystery.

I’ve reconstructed it here based on one of its more obscure possible relatives: the anthracotheres, a group which may have been closely related to modern hippos. Scaling its body proportions to these animals produces rough measurements of about 1.45m tall at the shoulder (4′9″) and 3m long (9′10″), or about the same size as some of the big entelodonts or large modern bears.

Homalodotherium, a South American notoungulate mammal from the Early-to-Middle Miocene of Patagonia (~20-15 mya). Standing about 1.4m tall at the shoulder (4′7″), it seems to have convergently evolved to fill the same selective browsing niche as the North American chalicotheres and the later giant ground sloths.

Despite being an ungulate it had claws rather than hooves, and walked plantigrade on its hind feet but digitigrade on its front feet. It would have been capable of rearing up bipedally to pull down branches with its long forelimbs, with the shape of its nasal bones suggesting it may have also had a prehensile upper lip to help it strip off vegetation while feeding.

The holy animal of Mongolia is big-headed and stocky, like a pudgy foal that overgrew in odd places. Its body is the color of a stirred cappuccino, but the legs are dark, as if dressed in stockings. Its muzzle is white, its mane black and bristly, erect as a fresh-cut mohawk. A matching line runs like a racing stripe all the way down the horse’s back. The babies are often pale gray, and woolly like lambs, and while any sensible human would immediately want to pet one, if not outright hug it, wolves see lunch.
If you were able to observe this creature in person, which is hard to do, given that they live in only a few places on earth, you would find it in a family network—a harem—with a dominant stallion watching over mares and their offspring, in groups of 5 to 15. For this to happen, you would have to be in Mongolia, Kazakhstan, China or Russia, the only places the horse lives anymore in the wild. Not so long ago, the species, once prolific on the Central Asia steppe, was one cruel winter, one hungry wolf pack, one outbreak of disease away from extinction.
This animal is generally known as “Przewalski’s horse” (pronounced shuh-VAL-skee), or “P-horse,” for short, but Mongolians call it takhi, which means spirit, or worthy of worship. You don’t ride the takhi, or stable it, or—pony-like as the horse appears—saddle it up and perch children on it at birthday parties. The horse is too wild for that. While it has been captured and occasionally confined to zoos, it has never been tamed—it is the only truly wild horse in existence. Other horses that are thought of as wild are in fact feral…

The Sumatran rhinoceros is actually the closest living relative to one of the world’s most well-known of the Ice Age megafauna, the woolly rhinoceros (last image).  This horned giant ranged all across Eurasia, from Korea all the way to Spain, and survived the last Ice Age before dying out 10 000 years later.  Originally this close relationship was only theorised due to the two animals’ similar woolly coats, but recent DNA analyses have proven that the two are sister species.  Some theories maintain that, in addition to global climate change, the woolly rhino was driven to extinction by over-hunting by humans, ironically the same thing that threatens the Sumatran rhino today.

I feel like people need to know the Great Moose Truths.

Despite people in Canada/New England feeling a strong pride and sense of ownership surrounding moose, Europeans have the exact same moose. English speakers completely fucked up the naming conventions for the animal because we fuck EVERYTHING up. 

The Eurasian elk is the exact same animal as the moose. It is Alces alces. Here is a depiction of a Swedish soldier riding a moose into war in the 1700s.

Figure 1. The Swedish army used moose as cavalry animals at various points in history. I don’t know what the armored boar is all about.

However, the English caused a lot of confusion by originally calling it an “elk.” This comes from the older English word eolc/eolh, which shares roots with elhaz/algiz, which, if you know your runes, is the antler-looking rune ᛉ. 

So the English had moose, they just called them elks. But there haven’t been any moose in the UK since the Bronze Age, so the English just started using the word “elk” to apply to “really big deer” - and they forgot that there was a specific animal they used to call “elk.” 

Today, modern people from the United Kingdom have overwritten their own understanding of “elk” with Elk (USA), which are wapiti (Cervus canadensis). 

This is a wapiti, which everyone calls “elk” now:

Figure 2. The wapiti, or elk  (Cervus canadensis)

“Hmmmmmmm,” British people may be saying right now. “That is a vaguely familiar animal. I feel like that is a STAG. I feel like it needs to be selling me a bottle of whiskey.”

YES. The wapiti is very similar to the UK’s red deer. This is what UK people call a “stag” : 

Figure 3. A stag, or British red deer (Cervus elaphus) - actually slightly less red than the wapiti.

The explanation for this is that the UK colonizers found the wapiti in the USA, but the problem was that red deer were rarely seen by the common people at that time, so they thought they were Unusually Big Deer. And so the colonizing bastards said “Hey, what are these, Nigel?” and Nigel was like “IDK, stags?” and they were like “Yeah but they look really big, don’t they?” and Nigel was like “well, what about calling them big deer, then” and they called them “elk” which at that point had come to mean “big deer” in English. 

Cervus elaphus (name meaning: deer deer) and Cervus canadensis (name meaning: Canadian deer) are very similar animals, and many people muddy the waters by calling Cervus elaphus an “elk.” The word ran all around the world, and American influence meant that it is losing its own definition in its own land. 

Cervus canadensis are also found in Asia, where the subspecies are called wapiti, from the Shawnee word meaning “white rump.” This is to prevent confusion. If you see one in Mongolia, you must properly call it a “Canadian deer, aka ‘white butt,’ from the indigenous North American word” to prevent this kind of confusion.

Figure 4. The global range of Cervus canadensis, the wapiti, or elk

Okay. Enough about what happened to the word “elk”. The point is that other European countries have reasonable amounts of moose, which they call elk. The “Eurasian elk” is Alces alces, the moose. 

Figure 5. A Swedish army representative wearing Swedish flags and riding a Swedish moose. ALSO, SOMEHOW, THE MOST CANADIAN THING EVER

So when the English settlers colonized Canada and New England, they continued their long history of fucking the fuck up. But in the middle of this, they saw Eurasian elks, had no idea what they were, and went with the local Algonquin word “moose.” 

They also called the same moose “elk” at the same time, and went into a slight confusion where they tried to differentiate them into “grey moose” and “black moose” and “black elk,” but when the dust settled, the world was left with British-colonizers-turned-Americans applying random names to everything, and winning. Wapiti are now called elk, and now red deer are also kind of elk. Eurasian elk are now moose. Wikipedia attempts to explain the moose fuckups here and the elk fuckups here.

The word “moose” is Algonquin in origin. This is why it doesn’t pluralize like English words do. In English, the plural of “goose” is “geese” and thus many people feel that the plural of “moose” should be “meese.” However, “moose” is not an English word. If you wanted to treat it as one, you could remember that moose are hoofed animals of a specific class, and you could follow the rules already laid down for moose relatives: The English plural of elk is elk. The English plural of deer is deer. The English plural of sheep is sheep. You can call multiple moose “meese” if you want to. But that’s why it is the way it is.

Figure 6. The global range of moose, or Eurasian elk.

So there you have it. Moose are an important, scary and hilarious part of Canadian/New Englander culture, but they aren’t just ours - we share them with Eurasian cultures too.

Figure 7: a Russian moose farmer with a promising crop

Figure 8: Finnish people provide a dark warning. “Hirvikolari” is a specific Finnish word describing a road accident involving a moose. There are many dashcam videos of hirvikolari on the Internet.

And now think about all the amazing Moose News you have access to now! You can now enjoy stories of moose destruction, mayhem and general fuckery SO MUCH MORE when you realize they aren’t about deer:

Figure 9: every line of this story is perfect?

Actually, you know what?

 That’s still the most Canadian thing ever.

I’M SO CONFUSED

(also, which one of them does Thranduil ride on?)

@shredsandpatches from how I remember the first Hobbit movie, I think it was a wapti?

A few people have asked this. Thranduil’s mount is a perfect Irish Elk (or more correctly, Irish Giant Deer), known as Megaloceros giganteus.

It’s a prehistoric giant deer, and not a close relation to the wapiti. (which is why paleontologists hope that we’ll start calling it an Irish Giant Deer instead of Irish Elk. TO PREVENT CONFUSION. IT IS NOT AN ELK!MOOSE OR AN ELK!WAPITI, IT IS A GIANT DEER. AND IT EXISTED.)

Figure 2. HOLY FUCK THE IRISH ELK.

Megaloceros went extinct about… 7000 years ago, and certainly did once coexist with humans.  There is a potential Folklore Ghost in the Irish word segh and the German work Schelch suggesting that Europeans may have kept their word for it, similarly to how the word aurochs is still extant, despite the Giant Fucking Killer Bull now being extinct. Anyway, it was definitely an animal and the prehistoric Europeans, Asians and North Africans who knew it definitely noticed it and thought about it, the same way that we all once knew mammoths. The Lascaux deer with palmate antlers was probably a Megaloceros.

Figure 3. HOLY FUCK THE IRISH ELK. Cave painting from Lascaux depicting a prehistoric deer with palmate antlers. Could be a reindeer, could be Megaloceros. The palms aren’t very reindeerish, though.

The LotR and Hobbit designers made the good decision of using prehistoric European animals as bases for the designs of the “fantasy animals” in the movies. Lots of fantasy designers do this. George RR Martin didn’t invent dire wolves, for example. The oliphants in LotR are based on prehistoric elephants, ditto and the orc’s war rhinos and the dwarves’ war pigs. The “wargs” aren’t actually dire wolves - which would be TOO CUTE AND BEAUTIFUL to be scary - but Dinocrocuta or Pachycrocuta, two kinds of giant prehistoric ancestral hyena.

Figure 4: Holy FUCK Dinocrocuta.

Anyway, it’s a good path to do down, because you can be incredibly lazy with the creature design, and take credit for all the cultural resonance it evokes. There is something about an Irish Giant Deer that just looks RIGHT, like EXTREMELY CORRECT AND PROPER, in a way that a made-up fantasy animal doesn’t always evoke.

Figure 5. Dire wolves weren’t actually that big. Smilodon (the sabertoothed cat) is smaller than a Cave Lion. Megaloceros is definitely big enough to ride, as is the spectacular wooly rhino, which always has my heart. The Aurochs (Bos primigenius) is there, looking fab.

And personally I think prehistoric megafauna are just so cool, and they just RESONATE. We spend all this time and energy inventing elves and aliens, looking to the stars and a fake fantasy past for cousins and creatures. Are there other humans out there that look like a different species but are still weirdly hot, and could we have sex with them? Are there recognizable animals that are like our animals, but with weird knobs and jaws?

But we did used to have them. We once had horse-sized war-pigs, giant wolves, lions the size of horses, elephants that bristled with teeth, armored beasts. We once had Other Human People, The Little People, the Neanderthals, with their own culture - and we totally slept with them. We had strange shamanic connections and early spiritual practices and ritual magic surrounding beasts, beasts that have only left ghosts. Because the world changed.

Figure 5. THE SCENE IN “BEASTS OF THE SOUTHERN WILD” WHERE SHE TOUCHES THE AUROCHS. I CRIED. IT FUCKING RESONATED. I MEAN THE AUROCHS IS MORE OF A GIANT PIG BUT IT RESONATED. 

But that’s why Thranduil’s war mount is not a moose (IT’S NOT A FUCKING MOOSE LOOK AT ITS FUCKING FACE) and not an elk (WHAT KIND OF FUCKING ELK HAS PALMATE ANTLERS) but a VERY SPECIAL AND MAJESTIC MEGAFAUNA.

I FEEL THE SAME WAY YOU DO ABOUT PREHISTORIC MEGAFAUNA.

IT’S JUST ALL CAPSLOCK ALL THE TIME FOR ME.

THEY FINALLY FOUND SABERTOOTH PRINTS AND I LEGIT CRIED ABOUT IT BECAUSE I COULDN’T  H A N D L E  IT.

FUCKING PALEO MAMMALS AMIRITE?!?!?

Footage of rare takins nursing captured in NW China

via: Xinua News

Cameras at a nature reserve in northwest China’s Gansu Province recorded wild takins nursing their young.
The pictures feature two or three mature takins tending as many as 15 calves in a mountain forest in Baishuijiang National Nature Reserve. The mature takins watch over their young while they nap, according to the photos shot from 12:56 p.m to 2:08 p.m. in April this year.
After waking up and foraging for food, the takins lay bask in the sunshine, showed the photos.
The cameras were installed in early April, and when they were checked recently, the pictures were discovered, said Wu Juncheng, head of the reserve’s Rangshui River Protection Station…
