Dispatches From South Dakota: Willie The Dimetrodon [Day 4]

Today’s post is from Michele Whisenhunt, a volunteer on the Museum’s paleontology team. She’ll be sharing photos with us while the team is at the Black Hills Institute, prepping Willie, the Dimetrodon the team discovered. Missed the team’s first dispatches? Day 1, Day 2 and Day 3

All work and no fun makes for a dull paleo preparer, soooo Mary Anderson, Pat Greenfield and I headed out early this beautiful morning for Custer State Park and a 14 mile drive where the buffalo and the pronghorn play. Autumn has hit in the Black Hills but the wildlife was worth the drive not to mention a glorious day. South Dakota is beautiful in so many ways.

Arriving early afternoon for prep work at the BHI our direction turned to beginning the bone cleaning under Dr. Bakker’s direction and the microscope.

After experimenting different methods of cleaning, a recipe was found. A vinegar bath gave the desired results.

Tomorrow will be the beginning of many days prepping thousands of bones to complete Dimetrodon for his 2012 premiere in the new paleo hall.
