Daspletosaurus prep update: now with arms

Hip block. Yowza.I know I've spent a lot of my previous blog posts focusing on the Platecarpus skull we were getting ready to send off witht he travelling circus to Tucson. Well, they're out the door and I can swing my attention back to our Daspletosaurus "Pete III".

Need some claws

Preparation is about 98% finished, with a few straggler parts and the pelvis block to finish up. We've also begun the restoration of some of the bones, partly for increased stability and partly because they're much less ugly now. Mark Wildman posted on his blog recently a tidbit mentioning Daspletosaurus had the longest forelimbs of any tyrannosaurid. I'm not sure if that's correct, however comparing our measurements with others published for Tyrannosauurs rex, we're a bit longer overall, even though we estimate Pete III to be nearly 10 feet shorter in overall length than "Sue".
The beginning of restoration of the arms
One of the nice things about preparing and restoring these bones (finally) is that we can uncover some new information about Pete III. Based on the size of its femur, we can estimate it was around 20 years old when it died, which is pretty old for Daspletosaurus. I've starting to use "it" when referring to Pete III because one of the next mysteries I hope to solve is whether it was male or female. Stay tuned for updates!
