I did want to mention that the palaeoblog's good friend, Mark Schultz, has generously allowed me to produce a print based on the reconstruction he did for me of Centrosaurus brinkmani. The 12"x18" (approx.) colour print will be signed by Mark and available from me or at the CMNH table next Thursday and Friday for $20. 100% of the proceeds go to fund student field work in Alberta with the Southern Alberta Dinosaur Research Group.
