Another conceptual illustration for the cast of the CAZ story in eternal development hell which I drew back in 2017. This one everyone should probably know, since it featured in an episode of Walking with Monsters (although depicted living anachronistically in the slightly earlier Lystrosaurus Assemblage Zone).
This animal would have been one of the closest dinosaur relatives known from the time period and location, slightly closer than Erythrosuchus, although it wasn't a direct ancestor. Still, this provides an early template for what dinosaurs evolved from about ten million years later.
I depicted it here as a facultative biped, although it was debatable even at the time and studies since have considered it a total quadruped so that minor detail would be changed now.
