As part of our weekend in the Chinle Valley, Jeff, Steve, and I revisted the quarry near Many Farms Lake where the Museum of Northern Arizona collected a fairly complete skeleton of the aetosaur
Desmatosuchus spurensis in 1999. This specimen was the basis for my Masters thesis (Parker, 2003) and a subsequent paper describing this specimen and revising the genus (Parker, 2008). I spent a lot of time in this place but had not visited since 2003. The excavation pit is still visible, but is reclaiming nicely. I took a few photos of the site and the surrounding area:
