Snakes have no bladder.
Chaperina fusca by Jono Dashper
hey I was the anon from sideofangels blog who sent the thing about the extinct crow, thank you for sending your ask because I'd never known that and it was really interesting! paleoart isn't something I've been interested in for a super long time so I didn't know artistic liberties were a thing with it or how factors about the environment would be used to fill in the missing peices of how an animal looked but that's really cool to learn
hello! yeah i studied this already during the pandemic so while on paper i’m qualified to do paleoart i don’t feel qualified bc the classes weren’t as practical or even as long as they would have been in regular conditions. so there’s a lot i still don’t know. BUT! an important thing here is that a lot of the time fossil reconstructions for actual scientific papers don’t have the whole animal (in the case of animals), they have reconstructions of the skeleton and of muscles, which are the most important parts for that kind of communication of those discoveries. a lot of reconstructions that have the whole animal (in the sense that they show the outside look) are meant for the general public to have a face to connect to the names so they seem more real, so to speak. it’s part sharing scientific facts part enticing the public to the field. so there’s more room for artistic liberties, so long as they make sense of course.
for example for my evaluation i had to a reconstruction of a sabertooth tiger that used to live in what is now portugal, and for the fur i based myself on the distribution of fur lengths in modern felines for the texture, and for the color i went about it from the environment perspective. bc i specialized partly in botany in my BA i know a few things about the history of portuguese flora, and because the muscle structure was similar to modern felines that hunt in a way that requires camouflage, i looked at modern areas that have vegetation similar to the possible habitats of that sabertooth tiger. and some of those areas have iberian wolves, a subspecies that is different from other wolves for a few reasons, including being adapted to camouflage in the local vegetation. so i gave the sabertooth tiger a color pattern similar to the iberian wolf’s. other people made it look like an actual tiger. it also depends on the illustrator, there’s different opinions on this and different ways to go about it. some may be very strict but my professor literally told us he once drew a dinosaur with a skin flap on its neck simply bc it looked interesting and nothing tells us that species didn’t have that

haven’t posted here in forever. truth is ever since I started having classes online my motivation went missing and I haven’t found it since. got pretty good grades on my second term but I can’t say I enjoyed all the hard work I did. today I got the good news that on Monday I’m finally going back to in-person classes and I’m thrilled!! until then, finishing off a ton of work I still have to deliver...

My friend and I were peering out from a nature overlook at my local park when she pointed out some movement in the bushes below us. It took us a bit to figure out what was going on but we soon realized we were witnessing the tail-end of a mighty battle between a little ribbon snake and one unlucky anole. Predation isn’t always easy to watch in the wild but it is still an important behavior that can teach us a ton about animal populations. Ribbon snakes do not prey on mammals, and will typically only eat “cold-blooded” prey such as fish, newts, earthworms, and frogs. This anole was a pretty big prey item for the ribbon snake to take on, and you can tell from the blood under the snake’s eye that this lizard did not go down without a fight.

I set up a hidden camera in the Kern National Wildlife Refuge in Kern County, California, near a known Cliff Swallows nesting area. These birds are amazingly vocal!
