Despite being a shabby, quickly-made sketch, my old dinosauroid (Anthroposaurus) and its quickly colored variant have remained popular, year after year. Since it's outdated and has some mistakes that bother me every time I see it, I thought it would be time for an update. Like the previous iterations of this concept, it's intended as a more "realistic" (a relative term in this context) alternative to supposedly Troodon-derived impossibly hyper-humanoid and reptilian dinosauroids, a meme that will hopefully go extinct soon.

Anthropoharpax sapiens is a highly derived originally African cenotroodontid that presently has a near-global distribution. Its earliest known ancestors resembled basal troodontids known from Yixian, but quickly adapted to an increasingly arboreal, probably insectivorous or omnivorous lifestyle. From the Cretaceous the clade is known only from teeth, but a spectacular fossil from the Messel Pit reveals by the Eocene they had reduced wing feathers, perching feet, opposable partially free digit III, possibly even a prehensile tail. Roughly 10 million years ago, in the Late Miocene, the ancestors of the anthropoharpagids moved down from the trees and began to explore the grassland biome. The modern Anthropoharpax evolved as a diurnal opportunistic omnivore, taking advantage of carrion, eating small animals from insect larvae to small mammals, raiding dinosaur nests, digging up tubers, eating berries, fruits, and whatever was available. Its long legs are an adaptation for long-distance endurance walking and maximal visibility in long savanna grass, and the reversed hallux of its arboreal ancestors has been lost.

Despite being highly modified, the hand of Anthropoharpax is less dexterous than our human hands. The second digit has only limited mobility and like in other dinosaurs, the wrist can't pronate. As a result Anthropoharpax often uses its jaws to hold tools instead, especially when precision is required. As a result it has a highly sensitive snout, comparable to our fingertips, and has evolved a special toothles gap in its jaws with specialized reinforced gum tissue for achieving a better grip. 

Anthropoharpax is a sexually dimorphic species, with mature males developing a head of long gleaming black feathers with patterns visible only in the ultraviolet spectrum. The males will engage in bouncy lekking dances to attract the attention of females. While tropical hunter-gatherer populations still sport the ancestral coloration, urban populations living in temperate climates show a great diversity in their plumage color. Even completely white morphs are seen where the diet predominantly consists of farmed plants.

I doubt predominantly predator species would evolve for eating so much plants but okay.
PS
I also have a question: who could be another sapient species of dinosaur if it wasn't troodon?

I don't understand why it's always the troodontids that get picked for sapience, and what they do to them. like what, because they're smart, and less smart than a crow or parrot?

also, some of the evolutions don't make sense, for example, why go through the long ass time to evolve hands when you could just use a mouth like tool using birds do?

It's a case of picking a dinosaur lineage that seems to have been brainier than the rest and going "what if they just kept getting brainier?" Evolution is never that simplistic, but it's not necessarily wrong to assume that troodontids could have given rise to the smartest non-avian theropods had the K/Pg extinction not offed them.

As for using their mouths, as you'll notice that is what Anthropoharpax uses for tasks that require precision. However, modern birds will tend to often use their legs for help because just the beak is often not enough. And when you have free clawed fingers, especially ones adapted for grasping, there's no need to bother using your legs. It's a natural progression from there.

then explain the evolution of said fingers

I'm not sure what you mean by that. You do realize that bony fusion of digits was a rather late development in Aves, right?

No. I'm just saying that the mouth seems to be more plausible. Take parrots and crows for example. They use their beaks to manipulate things around them, and said sapient troodontids wouldn't be doing any diffirent

What part of "birds also use their feet and it would make sense for troodontids to use their 'hands' the same way" do you have a huge problem with?

Tell me which part of this video proves your point.

ZOMG A SINGLE VIDEO OF A CROW MANIPULATING OBJECTS WITHOUT USING ITS FEET MORE THAN ONCE ALL OF MY LIFE IS A LIE!!!!!!111!!111

Is that the reaction you were looking for? Sorry, doesn't work that way.

It seems you also never explained the evolution of fingers yet. I'm just saying that plausibility wise, mouths and feet would be way better than evolving fingers.

If this was made for fun, however, plausibility wouldn't matter as much.

Great Dinosauroid, it is good to see the return of this old design with some improvements :)
Im curious about something, they have been able to develop a language? Do they communicate through birds-like sounds?
Osmatar's avatar

Thank you. :)
They certainly have a complex vocal language. The miniaturization of their arboreal ancestors lead them to abandon infrasound and develop something similar to a syrinx, but I haven't put that much thought into what they sound like exactly. I imagine their arboreal ancestors having tinamou-like calls and their more immediately ancestors sounding a bit like a kookaburras and great hornbills put together but the dinosauroids themselves must have more nuanced and varied repertoire of sounds.

you should make some weapons or some buildings of these animals homes

I'll see if I have time for that in the future.

Excellent design. Looks about like what one could expect a sapient troodontid would look like.
I also like how you gave your dinosauroids differences in plumage colour based on sex and on regional variations.

Thank you. :) I'm considering making a urban variant just for fun.

I love it! I want to sit down and have a cup of coffee with one :D (Big Grin)

Thanks! I actually have no idea how Anthropoharpax would react to caffeine. Probably the same as a bird of comparable size?
