Description

In my ongoing attempts to work myself paleoart-wise further down the avian stem (while still having to finish a drawing for a paleoart contest), this is Marasuchus lilloensis, the probably most basal dinosauromorph presented by more than just hind limb remains. This ferret-sized, slightly anorexical-looking thing was among the first animals of the lineage that led to dinosaurs (as opposed to any other clades of animals, such as pterosaurs or the crocodile-line pseudosuchians). Most of the head and - most frustratingly - the hands is conjecture, but the rest of the animal is fairly well-constrained, with several specimens to go with.

GSP - hat tip to him for the skeletal - illustrated it with a median row of osteoderms across its spine, but I couldn't find any sources confirming or denying their actual presence in the fossil material. I obviously went with my wide - avemetatarsalia-sized - bracket for fluffy integumentary fuzz on this guy. Speaking of Paulian implications, it would have been kickass to illustrate this thing in a bounding gallop as he did, but I don't know enough for that; given that he assumed basal sauropodomorphs as unambiguously bipedal-only as Plateosaurus were capable of that, I chickened out and depicted this tiny fellow leaping up at some insect or such.

Of course, in the name of hypothetics, you are correct. It can be difficult to get used to the unlinearity of nature sometimes - the fact that nature has no sense of "narrative consistency" :D The same thing that confuses people when they think of the evolution of humans, and see what a boggy mess it really is, with loads of simultaneous human species together, competing, fighting, even interbreeding. Neo-flightnessness is another example, "But didn't birds come from dinosaurs?" yes, and possibly dinosaurs came back from birds and that many times, just to really mess with our minds. It's entirely possible that scales became fuzz, and fuzz became scales again on larger, later animals. Nature has that habit of unpredictability sometimes :D
