Y'all ever stop and think about how if you were to design a bony fish anthro considering homologous structures it would look something like this

I mean it's basically what mudskippers have going on look at them standing on their little legs

Rabbits are not rodents!

*fairly long post about animal cranial anatomy*

Contrary to common belief, rabbits and hares (Leporidae), together with pikas (Ochotonidae), do not belong to the order of rodents; They are, instead, lagomorphs.

I won’t dwell on behavioral or dietary differences, but I will show you a small detail of the skull that makes them distinguishable at a glance. First, let’s see if you can spot it yourself!

Got it? The answer lies in the incisors. While rodents have a single upper pair, often (but not always) colored red or orange - lagomorphs have two pairs of incisors in the upper jaw.

These teeth are called peg teeth, and they help them grind fibrous food.

I had so much fun making this post 🥹 I hope you like it, maybe let me know if you would like more

I was wondering if I could animate walk cycles of your characters. I'll show them to you when I finish (if I ever do).

Oh wow, absolutely!! Blanket permission is given to anyone who wants to draw my characters! (Just don't be Weird Or Offensive™ with them)

If anyone is interested, this paper on Behaviour of Homotherium in the Light of Modern African Big Cats has some fun notes on possible locomotion of Homotherium!

Note to ecbear21: You absolutely don't need to read this paper for any walk cycles you do (or dont) make, I just like to provide sources for everything ever X'D

#mammothask #ecbear21 #ngl i dont really depict the more-pronate wrist on walking Homotherium #i think it kinda ruins the gesture of the pose and makes it look like im “dog artist draws cats” about it lolol #bc dogs walk pronated like the hyena in the picture and to me it's a hint someone learned to draw one before the other #(no shade im just a Chronic Observer who notices silly things like that XD)#homotherium #hyena #lion #paleo stuff #Mauricio Antón #sabertooth #mammothclan #sabercat #ooc ask #id in alt text #comparative anatomy

Got the Feline aspect of the jaw comparison done! If someone is into creature design, this'll help you figure out what kind of jaw your creature should have if they're precision, stalking animals!

The great cow-tipping conspiracy.

I grew up near a farm in Ontario before my family moved to Quebec, so I ended up learning quite a bit about farm life & farm animals. City folk have quite a lot of misconceptions about farm animals. Take the cow, for instance. There's a belief that country folk like to tip over cows for fun. This is a flat-out lie. To begin with, cows don't sleep standing up, so you wouldn't be able to sneak up on them, startle them & quickly push them over. Cows need to lie down to sleep because that's when they get their REM (rapid eye movement) sleep, which is crucial for memory consolidation, learning, brain development, brain repair, restoration & alertness. A study by researchers at the University of Tennessee shows that cows deprived of the ability to lie down can't get REM sleep.

Hypothetically, even if they did sleep standing up, cows weigh 3 times as much as a baby grand, which weighs 500 lb (226 kg); their center of mass is low & their stance is wide, so a person trying to push a cow over would require 2,900 newtons (N) of force to push one over. A newton is the force needed to accelerate 1 kg at 1 m/s², so you would need a sideways push of 650 lb of weight. But humans cannot generate 650 lb of horizontal push; even elite athletes max out around 300-400 lb of force in a controlled environment. Cow2s are basically biological refrigerators with legs. In addition, cows are easily spooked; they would either take evasive action & simply run away or start trampling people. The same thing goes for horses. True, they can sleep while standing, but only for naps or light sleep. They too need to lie down for REM sleep.

The next farm myth is that straw & hay are the same thing. No, it isn't. Hay is dried grass, clover, alfalfa, timothy, or legumes—anything livestock like to eat. Straw, on the other hand, is made from leftover stalks after grain harvests (wheat, barley, & other grains). It's inedible & is generally yellow in color. It's used as bedding, not food. Finally, let's tackle some bull. It is not true that bulls don't like or are afraid of the color red, despite what you see in bullfights. Cows & bulls cannot even see the color red. Cows have only photoreceptors, meaning they are dichromats, so they see only blue & yellow. Cows/bulls can detect light up to 555 nanometers (nm) in wavelength; the color red is between 620 & 750 nm. Cows can't see red. Red looks grayish-brown to them. Bulls charge at movement, so the bull reacts to the flapping of the matador's cape, & the red is there for humans.
