Digging Up the Past.

Here's an old one. I completed this pencil sketch in 2004, I believe. At the time, this was considered a male Corythosaurus casuarius, but more recent studies have suggested that Corythosaurus and Lambeosaurus may share a single genus under Hypacrosaurus (Paul, 2010). So as it stands today, I'll refer to animal in the sketch as H. casuarius; the sex is undetermined.
Concerning the accuracy of the illustration, it's fairly good overall. The most glaring mistake are the tubercles under the belly--they should be fewer in number and placed behind the legs, though in front of the ischium. Other than that, it's far too similar to Greg Paul's style for me to do anything with it... you know, beyond posting it as a curiosity of my past.
I hope you enjoy it!
