speaking of silesauridae- maybe there was a resolution to this and i just totally missed it, but i thought at some point i heard about a possible connection to pterosauria? is that a thing or am i buggin
That's Lagerpetidae! The other group of weird lanky Avemetatarsalians. We used to think they were on the dinosaur line, but now most researchers place them on the pterosaur line (it's only like, two steps different, again). Which is good, bc we did NOT have enough pterosaur ancestors before. heck, we still don't.

Okayyyy, back to posting art on here!! It’s been a while, but here’s the first piece that I created for @wtf-triassic, the tiny boi dinosauromorph Lagerpeton chanarensis. This small lad hails from the Argentinian Chañares Formation, and is about 235ma old. As a dinosauromorph, Lagerpeton falls just outside the line between dinosaur and non-dinosaur, which is a super abitrary line given how similar some of these species are to “true” dinosaurs. The Chañares Formation is full of other almost-dinosaurs-but-not-quite, making it a fascinating snapshot in time of the very beginnings of the dinosaurian lineage.
As an almost-a-dinosaur, Lagerpeton was probably covered in fluffy filaments, or “protofeathers”, since based on their existence in both dinosaurs and pterosaurs these fibres were likely ancestral at least to ornithodirans, the group that includes pterosaurs, dinosaurs, and vague difficult-to-define little things like Lagerpeton.
There’s not a whole lot special about this reconstruction in particular, I used my usual process for digital painting. I did make more use of textured brushes, which are an excellent way of roughing out textures that I highly recommend experimenting with. I might make a tutorial post on that at some point, it’s something I’ve found extremely useful.
I also chose to make him spotty, since for some reason there aren’t many reconstructions of spotty dinosaurs even though spots are everywhere in the animal kingdom. #bringbackspotsinpalaeoart2020 guys, let’s get that disgustingly-clunky tag trending.

Lagerpeton is known from the Chañares Formation in La Rioja, Argentina
Physical Description: Lagerpeton was named as the Rabbit Reptile, and for good reason - in a lot of ways, it represents a decent attempt by reptiles in trying to do the whole hoppy-hop thing. You might think that it resembles Scleromochlus in that way, and you’d be right! Scleromochlus and Lagerpeton are close cousins, but one is on the line towards Pterosaurs - Scleromochlus - and the other is on the line towards dinosaurs - Lagerpeton. So, hopping around was an early feature that all Ornithodirans (Dinosaurs, Pterosaurs, and those closest to them) shared. Lagerpeton itself was about 70 centimeters in length, with most of that length represented as tail; it was slender and lithe, built for moving quickly through its environment. It had a small head, a long neck, and a thin body. While it had long legs, it also had somewhat long arms, and while it may have been able to walk on all fours it also would have been able to walk on two legs alone. It was digitigrade, walking only on its toes, making it an even faster animal. Its back was angled to help it in hopping and running through its environment, and its small pelvis gave it more force during hip extension while jumping. In addition to all of this, it basically only really rested its weight on two toes - giving it even more hopping ability! As a small early bird-line reptile, it would have been covered in primitive feathers all over its body (protofeathers), though what form they took we do not know.
By Scott Reid
Diet: As an early dinosaur relative, it’s more likely than not that Lagerpeton was an omnivore, though this is uncertain as its head and teeth are not known at this time.
Behavior: Lagerpeton would have been a very skittish animal, being so small in an environment of so many kinds of animals - and as such, that hopping and fast movement ability would have aided it in escaping and moving around its environment, avoiding predators and reaching new sources of food (and, potentially, chasing after smaller food itself). Lagerpeton may have also been somewhat social, moving in small groups, potentially families, to escape the predators and chase after prey together, given its common nature in its environment. As an archosaur, Lagerpeton was more likely than not to take care of its young, though we don’t know how or to what extent. The feathers it had would have been primarily thermoregulatory, and as such, they would have helped it maintain a constant body temperature - making it a very active, lithe animal.
By José Carlos Cortés
Ecosystem: Lagerpeton lived in the Chañares environment, a diverse and fascinating environment coming right after the transition from the Middle to Late Triassic epochs. Given that the first true dinosaurs are probably from the start of the Late Triassic, this makes it a hotbed for understanding the environments that the earliest dinosaurs evolved in. Since Lagerpeton is a close dinosaur relative, this helps contextualize its place within its evolutionary history. This environment was a floodplain, filled with lakes that would regularly flood depending on the season. There were many seed ferns, ferns, conifers, and horsetails. Many different animals lived here with Lagerpeton, including other Dinosauromorphs like the Silesaurid Lewisuchus/Pseudolagosuchus and the Dinosauriform Marasuchus/Lagosuchus. There were crocodilian relatives as well, such as the early suchian Gracilisuchus and the Rauisuchid Luperosuchus. There were also quite a few Proterochampsids, such as Tarjadia, Tropidosuchus, Gualosuchus, and Chanaresuchus. Synapsids also put in a good show, with the Dicynodonts Jachaleria and Dinodontosaurus, as well as Cynodonts like Probainognathus and Chiniquodon, and the herbivorous Massetognathus. Luperosuchus would have definitely been a predator Lagerpeton would have wanted to get away from - fast!

Other: Lagerpeton is one of our earliest derived Dinosauromorphs, showing some of the earliest distinctions the dinosaur-line had compared to other archosaurs. Lagerpeton was already digitigrade - an important feature of Dinosaurs - as shown by its tracks, called Prorotodactylus. These tracks also showcase that dinosaur relatives were around as early as the Early Triassic - and that their evolution, and the rapid diversification of archosauromorphs in general, was a direct result of the end-Permian extinction.

Name: Lagerpeton chanarensis
Name Meaning: Rabbit Reptile
First Described: 1971
Described By: Romer
Classification: Avemetatarsalia, Ornithodira, Dinosauromorpha, Lagerpetidae
Lagerpeton is another early derived Dinosauromorph, known from the pelvis, hindlimbs, and some vertebrae, however, a lot can be gleaned about the animal regardless. It was found in the Chañares Formation of Argentina, as well as the Ischigualasto Formation of the same country, and the Chinle Formation of Colorado. It was about 70 centimeters long, and it would have been a very slender, lithe animal, fast moving, active, and potentially covered in filamentous integument. Footprints have even been assigned to the genus, namely, those of Prorotodactylus, showing a digitigrade posture and similar digits to Lagerpeton. It may have been saltatory, jumping and running through its environment - as indicated not only by its legs and activity, but also by the incline of its neural spines on the its vertebrae, not seen in other archosaurs. It has a very small pelvic girdle, allowing for an increase in force during hip extension in jumping. It also had very narrow, essentially two-toed feet, further allowing for hopping by the animal. It would have been a very fast, active animal in its environment, showing a distinct and unique niche occupied by early derived relatives of dinosaurs during the Late Triassic.
