kulindadromeus zabaikalicus

Big News!

Its only been a wonderful 4 and a half months, but our @huxley-paleozoo blog finally has 500 followers! 500 people, all united by a love of the past and our goal of bringing it into the present, for science! We would’ve had a bigger celebration, but… 

One of our Kulindas bolted during a routine medical check and stole the banner… 

Thank you, all 500 of you, for following! See you at 1000!

Kulindadromeus zabaikalicus

By José Carlos Cortés on @ryuukibart​, made for his project, The Liberal Dinosaur Fan! Check it out at @liberaldinosaurfan!

NameKulindadromeus zabaikalicus 

Name Meaning: Zabaikal Kulinda Runner 

First Described: 2014 

Described By: Godefroit et al. 

ClassificationDinosauria, Ornithischa, Genasauria, Neornithischia

When this dinosaur was discovered, it rapidly rose to the fourth position in my favorite list - and it’s obvious why. This dinosaur proves pretty clearly that feathers were synapomorphic for both Ornithischia and Saurischia (something I have been suggesting for years due to quills being found on another basal ornithischian, Tianyulong, as well as protofeathers found on Psittacosaurus, and the presence of feather protein genes in the crocodile genome, suggesting that protofeather-esque filaments are a trait of all of archosauria, based on cladistics. Genomes, man. Genomes.) It was found in the Ukureyskaya formation in Russia, which dates back to the middle to late Jurassic, about 169 to 144 million years ago in the Bajocian to Tithonian ages. It is known from a partial skeleton in rock that lead to amazing preservation of both feathers and scales. Now, this fossil was stolen and described as another species, Kulindapteryx, but this is not valid and should be ignored (curse you, BANDits.)

Kulindadromeus was a bipedal runner, about 1.5 meters long, with a short head, short forelimbs, and long hindlimbs and tail. It had scales on the top of its tale and scales branching into feather like structures on the main part of the body. This fuzz all over the body are hair like filaments like stage 1 dino fuzz on Sinosauropteryx, and then another type is longer filaments on the upper arms and thighs like type three feathers, and then unique bundles of ribbon like structures on the upper lower legs that are made from parallel filaments.

Kulindadromeus also had three types of scales: overlapping hexagonal scales on the lower shins, non-overlapping scales on the hands ankles and feet, and arched rectangular scales on the tail, forming rows.

According to the science of evolutionary cladistics, the closer two clades are related to one another, the more likely any features shared by those clades was only evolved once, in their last common ancestor. More deviated groups - such as birds and bats - that share a feature evolved them separately. As such, the fact that crocodiles have a dormant feather gene (same protein) implies that the last common ancestor of both crocodiles and birds had feathers - and that’s just from genomics. 

By myself (Meig Dickson) and John Turmelle on @killdeercheer

Now, while this feature may have been lost in many archosaurian species - as fur is lost in many species of mammals - it is important that we now, as paleontologists, switch our line of thought from “scaled until proven otherwise,” to “feathered until proven otherwise.” The discovery of so many feathered or quilled theropods - as well as quite a few quilled and feathered ornithischians, now - only bolsters that claim. This is by far one of the most exciting discoveries of modern paleontology, and I can’t wait to see what more we find out about the connection between dinosaurs, birds, and feathers in the coming years. 



Shout out goes to prehistoric-birds!

Also, the moral of today’s story is NEVER TRUST A BANDIT 

I drew this little guy last year for @a-dinosaur-a-day’s celebration of the ornithopod dinosaur Kulindadromeus zabaikalicus. Kulindadromeus was a huge discovery, an ornithopod with feathers! Before this, the only feathered dinosaurs were from the theropod group, but Kulindadromeus shows that feathers were much more widespread across the dinosaur family tree. 

This effect has been lessened a bit by the new Ornithoscelida proposal, which would make theropods and ornithopods much more closely related than previously thought, but Kulindaromeus is still an amazing milestone of dinosaur palaeontology. And it’s also adorable.


This day 2 years ago Kulindadromeus zabaikalicus was discovered and so our understanding of dinosaur feathering was changed forever! As you may recall K.B. himself is one of these very important little dinosaurs!

So it is indeed also K.B.’s birthday! YAY! 

To celebrate, a bunch of Palaeoblogs are organizing a stream in a little while! 

I’ll be there too! (In fact I’m hosting the stream XD) I’ll be sure to link you all to it as soon as it starts!

anonymous asked:

Has evidence of feathers been found on a dinosaur other than a theropod?





In fact, it’s more likely than not that dinosaurs were ancestrally feathered

anonymous asked:

regarding these feathered dinosaurs topic, is it there any idea on their resemblance? Sorry, badly worded, I mean, is it know how the feathers could have looked like? Would they have resembled modern bird's ones or were they too small and short to be considered as such? Also, are there any papers/reports/books/articles/whatever you can recommend that tackle feathered dinosaurs? Thanks in advance btw!

They looked kind of like fur. We have a pretty good idea of what they looked like at different evolution stages

and there are plenty of articles and books out there! I recommend A Field Guide to Mesozoic Birds by Matt Martyniuk
