The Hunchback of Las Hoyas

Concavenator has to be one of the most baffling dinosaurs discovered in recent years. Named in 2010, this Spanish predator conforms to most carcharodontosaur anatomical conventions, apart from the two extremely high vertebrae before its hips, which may have supported a camel-like hump in life. This dinosaur was also initially believed to have had quill-like feathers along on its arm (a la Velociraptor, which has been found with feather-anchoring knobs along its forelimbs), but this hypothesis has since been criticized by experts like Darren Naish.

Initially, this sketch was going to be a full skeletal recreation with the living dinosaur stalking somewhere behind the stone slabs. Due to lack of space, however, I decided to split the specimen between fossil and carcass right where the two higher vertebrae meet, and the drawing is now better for it. The coloration is based on the Gila monster, a modern predator that thrives in harsh conditions, while the little black dots you see around parts of the corpse represent carrion-feeding flies.
