Nesting holes by Hyrotrioskjan Nesting holes by Hyrotrioskjan
Is it possible that non-avian dinosaurs nest in small self-dug, or captured caves? and if yes, what species would be suitable for this behavior?
These were the questions which grew into my mind when I thought about nest forms.
I finally choose Epidexipteryx. Why?
Let's begin with the enviroment of E. hui. The specimen was found in china, inner mongolia, within the Daohugou beds which are between 168 and 152 million years old. It was a wet ecosystem with lakes and streams, it was the home of the first known aquatic mammel, Castorocauda, which was maybe also a digging animal.
Vulcanic ashes are known from the fossil beds, a material which may form huge river banks and small canyons, here a example: [link] a enviroment.
Epidenxipteryx may used such walls to build it's own holes. The animal is really small (25 cm without the tailfeahters) and light (160 g). The long fingers and possible presence of grasping claws, like Epidendrosaurs (I would have chosen this species, but we just know juveniles), make a climbing lifestyle practicable. The teeth are not visible here because I cover them with lips (inspired by Quilongs Masiakasaurus ;)) but they were huge for a animal of this size and may help to dig into the clay of the cliff. In addition a short tail, like found at Epidenxipteryx, could be usefull; even if I have reconstructed the animal here with the iconic four tail feathers it's possible that these were just seasonal phenomenons which disappear after mating.

I have this drawing since two weeks but until now I find no way to bring it in a digital form (it's larger than the other pics for the All Yesterdays contest).
But it fits better now, after submitting the nesting pterosaurs and because of this Cryolophosaurus which arrive today on DA: [link]

hmmm.... in retrospect of this piece, do you think Yi qi's wings maybe have doubled as Digging spades?

Why can't we clone these by know? I mean, we almost gotten to the point were we can clone wooly mammoths. And these are adorable. If we could tame them it would be like having mega birds for pets. And I think that would be cool ;p

Well, like radioactive elements, DNA has a half-life, after roughly 10000 years most of it is gone, even under exceptional conditions.

Well if technology can reach it we can do it. And we all know that'll happen.

It's not that easy, pure will can't change the laws of physic. Mammoth? Maybe, not impossible. T. rex? Very unlikely.

But wouldn't it be cool to eat mammoth steak? Come to think about it I could go for some steak right about now

One time I was on a dock thing and lost my bag of Cheetos in the water. There was a small ledge just above the ocean so I climbed down the structure holding the dock up and finally reached the ledge and walked out on it, moving to a pillar. As I reached for the Cheetos I noticed there was a lot of chirping coming from a hole near my head so I leaned down and looked in it only to be attacked by a freaking bird. It pecked the crap out of my face and I fell in the water. Something bumped my leg in the deep water after I almost got stuck in the seaweed which is why I hate the ocean and docks around it. I fear the ocean because of birds.

And i somehow start wondering if Dinosaurs did not roar, much like their modern cousins, but instead growl or hiss, except during mating season

FUUUUUUU!!!
I was also working on something similar, only with Microraptors instead of these guys... Well, i'll have to draw something else ;)


(by the way, i haven't posted yet any of my AY contest drawings because you don't have the idea how friggin' hard is to find a scanner... Just taking a pic of 'em with my camera don't give 'em justice!)

You can submit it also, would be nice to see another version of this concept.
I was also a bit grumpy when I saw Quilongs fuzzy ankylosaurs but I will submit my version now too =)

It's indeed very dificult to get good photos of drawings, if you don't find a scanner you may find a tutorial for such photos.

ah ja, stimmt, ich wusste es kommt mir von irgendwoher bekannt vor. Das einzige was ich mir nur frage is ob das tier tatsächlich federn an den armen hatte. Sowei ich weiß wurden ja keine gefunden obwohl man ja flaumenfedern am körper fand. Auf jedenfall sieht er mit armfedern besser als ohne aus :D

:iconhyrotrioskjan:
Hyrotrioskjan Featured By Owner Jan 24, 2013  Professional General Artist
Es sind keine Schwungfedern überliefert also hab ich mich auf Konturfedern beschränkt die etwas länger sind. Es gibt die Theorie das die Scansoriopterygidae von gleitenden Tieren abstammen und das wollte ich in diesem Fall betonen =)
