Cadurcodon ardynensis was an odd-toed ungulate that lived in what is now Mongolia during the late Eocene, about 37-34 million years ago.

It was around 2m long (6'6") and, despite its very tapir-like appearance and lack of horns, it was actually closer related to modern rhinoceroses – it was part of a group of early rhino-cousins known as amynodontids, which convergently evolved both hippo-like and tapir-like lifestyles.

Cadurcodon was the most tapir-like of the tapir-like amynodontids, with a short deep skull and retracted nasal bones that indicate it had a well-developed prehensile trunk. Males also had large tusks formed from their upper and lower canine teeth, which may have been used for fighting each other.

Taxonomy Tournament: Mammals

Pholidota. This order is made up of the pangolin, the only mammal to have keratin scales.

Perissodactyla. This order is also known as the odd-toed ungulates because they (mostly) have hooves and bear weight on one or three toes. It is made up of equines, rhinos, and tapirs.

Uncharismatic Fact of the Day

One of the most iconic symbols of freedom and wilderness is the wild horse; it's fitting, then, that the Przewalski's (sheh-VAHL-skee) horse is known as "takhi," which means "spirit" in Mongolian.

Looking at the their small, flexible proboscis (snout and upper lips) and thick, rough skin, the casual observer might think the tapir is a relative of pigs, or related to anteaters or elephants. Its closest relatives are actually the horse and rhinoceros. Similar to their earliest hoofed ancestors, tapirs have four toes on the front feet and three toes on the hind feet. The toes are separated widely, with the middle toes larger than the others. All toes have hooves, and each foot has a callous pad which supports some of the weight.

At first glance tapirs may look like slow and clumsy animals, and an easy catch for predators. In fact they're very capable! Tapirs have recessed eyes and short ears, legs and tail. They also have a stocky body that is rounded in back and tapered in front. When threatened, their compact and streamlined shape enables them to crash through the thickest forest underbrush with remarkable speed. They are also excellent divers and swimmers, and seek refuge from predators in deep waterways, where they can remain submerged for several minutes. If cornered the thick, hard skin on its neck helps to protect it from a predator's sharp fangs. Tapirs also have strong jaws and large teeth that can inflict a serious bite. ©

Absolutely! I love the way they look.

There are under 16,000 white rhinos left in the wild; the northern subspecies is functionally extinct, with only two older females left in the world. So all that remain are a few thousands southern white rhinos, to include those in captivity.

The guy who owned this white rhino ranch lobbied to have the South African ban on rhino horn sales lifted, even though there are international bans still in place such as the Convention on International Trade in Endangered Species. He had cut the horns of his rhinos to keep them from being poached, and stored them away. In spite of having hundreds of millions of dollars worth of horns in his possession, he wasn't able to continue buying feed for 2,000 rhinoceroses, hence the sale.

I don't know whether that sale includes the detached horns or not. It's maddening that as we approach 2024 there are still people who will pay exorbitant fees for rhino horns as a medication even though there's zero evidence it has any effectiveness, and there are likely collectors who want one simply to have it due to their rarity. I don't know enough about the potential for legalizing trade in horns cut off of living rhinos with the aim of making poaching less lucrative to have an opinion either way, but having seen how much misrepresentation and outright lying can happen in the global trade of animal remains I'm not feeling optimistic about this as a solution.

I am, however, grateful that this massive herd of highly endangered animals--about 15% of the world population of white rhinos--are now in the hands of those who are going to get them back out into the wild, albeit in protected areas. Here's hoping that these rescued rhinos will be able to add more genetic diversity back into the wild populations and strengthen them for the future.

stormie

four years ago I did a roleplay where my rat oc amalthea befriended a horse. the horse protected her from predators, it was really fun! and later I also got to roleplay as the horse's filly, which is the character here. I remembered that our horse characters were both white & gray & inverts of each other, but I forgot which one was gray with a white mane & which one was white with a gray mane..

several times I tried to contact the other roleplayer about this, but they never replied. maybe they don't check their messages anymore. I really wantex to get stormie on artfight this year so I ended up making two versions of her. I wish we coul continue the roleplay, but knowing it's been 4 years noe I wonder if they even remember.. it's sad to me how I always seem to be more invested in roleplays & continuing them than everyone else I roleplayed with, and I remember them for years if not forever while they forget somrtimes only after a few months..

it hurts to be the only one who cares! anyway, I think amalthea would've helped look after stormie just as stormie's mother helped look after amalthea's own pups :) I should draw amalthea & stormie together some time, it'd be so cute!! I probably won't do it for some months at least though..

rn I'm really busy trying to make drawings of my characters that were supposed to be on my artfight roster this year but I haven't drawn yet/really need to redraw or redesign, and after artfight is over I might takr a break from drawing (won't stop posting art though, this artfight prep has given me a buffer), & when my break is over I think I'm gonna prioritize primeval age stuff for a little longer. & by then I might've forgot about this idea.. eh, it'll probably come bsck to me one day!

Black Rhinoceros (Diceros bicornis)

In the mood to draw rhinos. It's curious how in the two African species the horns sometimes grow ridiculously long.

The pose and perspective made this fellow challenging to draw and to shade, but it came out quite alright.

Ha, ha, you're not going anywhere! Idiot!

Spent the day at UF’s large animal hospital and got to see this :) This is a Thoroughbred named Sling going 37 miles an hour. Unfortunately, I caught this at the end as he was coming down from the speed. I love my school!
