flocking 3/21/25—Thescelosaurus, Sauroposeidon, Vespersaurus

i have not been on here much due to print fair insanity (which went great, if you were wondering!) followed by ongoing illness (not going so great) but i am trying to get through a little backlog of posts in preparation for my website revamp. and welcome to all the new followers also :D

here's today's #Paleostream sketches!!!

today we sketched Sauroposeidon, Thescelosaurus, Vespersaurus, and Knoetschkesuchus

Archovember day 7! Vespersaurus paranaensis! A small Theropod from the Cretaceous! I know that its unscientific that this animal would have the ability to poof up their plumage this much, but all the images I saw of them reminded me of pigeons and I pictured them doing a little courtship dance. Whats interesting about these animals is that they walked around on one middle toe rather than all three and so had the two outer toes up in the air.

Archovember 2024 Day 7 - Vespersaurus paranaensis

The rare noasaurids were a family of theropod dinosaurs belonging to the group Ceratosauria, and were related to the short-armed abelisaurids. One noasaur, Masiakasaurus, brought the family into the limelight recently with its appearance on Prehistoric Planet. But in Cretaceous Brazil, a different noasaur left its strange, monodactyl footprints across the sand. Vespersaurus paranaensis had two “killing claws”, on each foot, but not like a Velociraptor, or a Balaur, or even like modern Accipitriformes. Instead, it walked on its middle toe, while its 2nd toe and outer toe were raised off the ground. This may have been an adaptation to moving swiftly across the hot sand of the Botucatu Formation, a vast Cretaceous desert. Such an adaption has not been found in any other archosaur. Vespersaurus probably didn’t actually use these claws for hunting, and was likely a generalist, chasing down small, fast animals, opportunistically scavenging the kills of other predators, or hunting weak and injured animals. It may have instead used its claws in powerful defensive kicks, similar to modern cassowaries.

Other named species have yet to be found in the Botucatu Formation. Aside from Vespersaurus, other fossils include indeterminate coelurosaurs, ornithopods, lizards, tritylodontids, and mammals.

Vespersaurus paranaensis

A young berthasaura narrowly escapes the jaws of a predatory vespersaurus. Despite appearances, these two are actually quite closely related, both being part of the clade noasauridae. These were a group of ceratosaurid theropods that were quite varied in forms, among them small hunters and beaked herbivores that lost their teeth as they grew up.

Not entirely sure whether these two lived together but I really like the contrast of how different yet also how close these two are. Also vespersaurus is one my favourite dinosaurs ever.

The last day of dinocember 2023 is day 15: Vespersaurus.

Vespersaurus paranaensis, a strange ceratosaur theropod from Late Cretaceous Brazil. Only one middle toe on each foot bore most of its weight, an adaptation that aided it in its desert environment

Archovember is here once again! Looooots of theropods this year. Also a lot more dinosaurs in general than other archosaurs. Sorry. There were just too many I wanted to add!

I also apologize that there are several redraws in this list… I included a couple animals I’ve drawn for past Archovembers that I wasn’t quite happy with (7 to be exact, oop). If you’ve been drawing along since the beginning and don’t feel like drawing a repeat, feel free to substitute a related species!

For new folks: this is my “Draw Dinovember” list that I expanded out to include other archosauriforms. I started doing this a few years ago to challenge myself to draw species I’ve never drawn before and/or ones that don’t get a lot of attention. Feel free to join in! You can do the whole list, just the dinosaurs (the names in green), just the pterosaurs (orange), just the pseudosuchians (blue), just the 3 oddballs (red), just your favorites, just ones you’ve never drawn before, pick one blindly, roll a D20 and a D10 and draw the sum of whichever numbers you get, etc. Just make sure they’re posted on or after their specific day! You can use #Archovember or #Archovember2024, as those are the tags I follow. Be as detailed or as sketchy as you’d like! I’ll be leaving the story highlights on my Instagram (also SaritaPaleo) from last year’s Archovember up until November 1st, if you’d like to see what people have done in the past! (This challenge usually gets a lot more traction on Instagram; so I would recommend checking it out there if you have one!)

As a disclaimer that I am obligated to give every year: when you are looking for refs for some of these species you will come across David Peters. This guy posts a lot of pseudoscientific images featuring lesser-known species, and his stuff can sometimes dominate search results. Do not trust anything from sites called “Reptile Evolution” or “The Pterosaur Heresies.” Peters’ constant outpouring of material has a habit of clogging up search results, misleading and tripping up people who may be trying to get into paleoart. He fooled me when I was first starting out! If you’re drawing along and are having trouble finding legit references, send me a message and I can send you what I’m using!
