I've found this nifty reference website for artists called www.dimensions.com that has a database of exact measurements for various objects, plants, and animals
They have a premium version with 3D models that I haven't tried yet, but it's definitely very informative if you're trying to get the anatomy and proportions for different species of animals right!

Based on a recent Twitter discussion
Gular glands in crocodiles are one thing, but many are also not aware of the facial and movable glands in muntjacs.
Tumblr media Tumblr media
These structures aren't really sexy so they are often omitted from documentaries. Here a video of them in action that made it's rounds some time ago.
Utterly bizarre when you are not familiar with them. It often makes me wonder what kind of glands we might miss in paleoart. Uropygial glands in birds for example, when did they evolve? Did non-avian dinosaurs already have then or did they use another, analogous structure during preening?
Tumblr media
Another example are enlarged skin glands like the poison glands in many amphibians. Could temnospondyls already have something like this?
Just remembered, duikers are a good example of large preorbital glands as well, often appearing as prominent slits and pouches in front of the eyes. Some oreodonts like Eporeodon might had have similar structures.

"Owl studies"
I've always found owls fascinating. The barn owl is definitely my favorite with its beautiful feathers and elegant shapes. Here a selection of some studies I've been doing.

Upper: Skull of adult male wolverine showing that all sutures have disappeared. The caudal extension of the sagittal crest is clearly shown. About 1/2 natural size.
Middle: Skull of immature male wolverine showing the internassal, naso-maxillary, the naso frontal and the malar-temporlar sutures still open. The sagittal crest is less well developed than in the adult male. About 1/2 natural size.
Lower: Bacula of adult males on the left and immature males on the right. About 1/2 natural size.

This may be a kind of weird and silly question, but do you know how far giraffes can turn their necks? I’ve only ever seen them looking straight ahead or a little to the side, but the neck is so long that I wondered if they could turn to look past 90 degrees..... I couldn’t seem to find anything online!
They can (and do) nap with their heads resting on their own butts! Giraffe necks are very flexible.
Here’s a still from a video my friend K. Dodge took at Cheyenne Mountain Zoo recently, which is a perfect example of that range of motion. (In the video, it looks like there’s an itchy spot at the shoulder there.)
Tumblr media
I wanted to include a photo of giraffes actually napping with their head flipped around onto their backs for you, but I don’t want to pull one without a source off of Google - so if anyone has one they’ve taken themselves, please add it to this post!

hey uh. I just saw a tiktok. Are owls eyes tube shaped???? Are they not orbs????
(I could Google this of course but I thought this might be something you either very much enjoy or very much hate about owl anatomy and I want your opinion on it with the answer)
yeah it’s why no matter how annoyed they are by humans they can’t roll their eyes about it.
Tumblr media
Though I would describe the eyes as bell-shaped, not tube-shaped. The “tubes” seen on this skull are just the scleral bones, which are present on most if not all birds and function as a sort of corset to help the eyes maintain shape and structure.
Tumblr media
All birds have bell eyes to an extent, but owls do have longer eyes, in part due to how long their scleral bones are relative to the size of the skull.
Tumblr media
The eyes take up so much of the skull that you can actually see the back of the eye by looking in the owl’s ears (seen in gray above). This is a large portion of why owls don’t like to be petted on the head or face. Aside from their crines (whiskers) having extremely sensitive nerve endings leading to overstimulation, there’s a good chance you’re also poking the bird in the eye in most of these spots. Ouch.
