Eosinopteryx brevipenna by T-PEKC Eosinopteryx brevipenna by T-PEKC
Reconstruction of the newly described feathered non-avian dinosaur from the Late Jurassic of China, Eosinopteryx brevipenna. Eosinopteyx is small, only 30 cm long, troodontid theropod similar to Anchiornis and Xiaotingia. Unlike those taxa, Eosinopteryx lacks leg-wings typical for most of the known primitive troodontids and dromaeosaurs, and also shows no signs of tail fan. These characteristics are interpreted as adaptation for cursorial life-style.

This drawing is also my fourth entry for “All Your Yesterdays” contest. The speculative concept I’m exploring here is the presence of albinism in some non-avian dinosaurs. It’s true that this is relatively rare condition in modern archosaurs (birds in general, I don’t know for albino crocodilians), and most albino individuals rarely survive for long in nature, but it still is possibility. In some cases, as with pigeons, in city environments where only few or no natural predators are present, albino animals are common sight. It’s typical for albino birds to face aggressive behavior from the normally colored birds of the same species.

Here, two “normal” individuals of Eosinopteryx are picking on their albino relative, due to its different look in comparison to the rest of their population.

Might as well be the cutest dinosaurs I've ever laid my eyes on!

There is an albino alligator at the California Academy of Sciences in San Francisco ;)

Beautifull work. Very interest this idea, also, very plausible.

Thank you!

I think it's even more than plausible, and I'm wondering why more paleoartists have explored this concept already.

Is it possible that Eosinopteryx is simply a juvenile troodontid and has undeveloped leg "wings" in the same sense today's birds don't have well-developed wings when young, rather than being a separate species?

It's possible scenarion if it's indeed an young animal, but I think this is unlikely to be the case here. It's true that there is no mentioning in the paper that the specimen is an adult animal, but if it was juvenile I'm sure the authors would have said that, because the ontogenetic state of the animal can greatly affects any conducted cladistic analysis.
