Dryptosaurus aquilunguis is a primitive tyrannosauroid theropod from the Maastricthian of East North America (the subcontinent Appalachia). Even though Dryptosaurus is one of the first named dinosaurs in USA, it's not very popular outside the paleontological circles. This is caused by the very fragmentary nature of its fossilized remains. It's estimated to be a little over 7 meters long, and as a primitive member of the clade had three fingers on each hand, unlike more derived members (as T. rex) which had two.
Here, Dryptosaurus aquilunguis is laying on one side on the ground, resting, being sick or dying (it's your choice). The resting positon of the animal is inspired by recent discussion over Hell Creek's forums.
This reconstruction is higly speculative. The long head is based after other tyrannosauroids as Eotyrannus, Appalachiosaurus, Guanlong and Dilong and the nasal ornamentation is hypothesized on the base of presences of similar structures in Guanlong, Yutyrannus and Alioramus. As the fossils evidence shows tyrannosaurids were atleast partly covered by feathers. Following the rumorms of fossilized patches of T. rex's skin showing regions covered with tiny scales and/or naked skin, I included these types of integument in this restoration. The underside of the animal is covered with large subrectangular scales, which get finer in the upper parts of the body. Legs are also scaly, as in most theropods. Naked skin is present on thighs, parts of the tail and over the ribs.

You're right about the claws, they should be considerably bigger than that, it's my mistake. In my attempts to not make them too big, I ended up drawing them too small. If I ever need this work involved in any project, I'll fix claw's size.
I don't like going back to old works and fixing them, unless I'm somehow forced to do it by some reasons. Mistakes are part of each artwork and they remind me what I need to improve or to not do again. Usually I prefer making a new drawing instead of reworking an old one. It may not sound logical, but that's how I work.
Great work! It's always nice to see animals from Cretaceous Appalachia, which are represented in far too low numbers. But apart from Dryptosaurus and Appalachiosaurus, what other fauna has been recovered from Cretaceous Appalachia
I see Dryptosaurus as having much bigger claws, judging from the fossil remains I have seen pics of.

Well, another one would be Hadrosaurus, also I think there are a lot of very fragmentary dinosaur remains from Appalachia.
Wikipedia has a short list with Appalachian dinosaurs - [link]. I have no idea what the rest of the fauna was like.
