Volunteer Don Phister begins to carefully remove the overburden on top of the stegosaurus. The Big Horn Mountains are in the background.
Volunteer Robert Boscarelli takes time off from digging to phone home and tell his wife of the discovery of Sarah the Stegosaurus.
The digsite prior to removal of the overburden by the diggers and the trackhoe.
Our site supervisor, General Patton, was ever-present, making sure the dig was progressing at a good, safe pace.
A view from the Stegosaurus digsite down towards a lower site (near the Suburban). The overlying Cretaceous-age Cloverly Formation is on the hills in the background.
Robert Boscarelli and Bob Simon are shown at the digsite during the initial excavation.
Robert Boscarelli and Bob Simon are just beginning to expose the Stegosaurus skeletal elements. At this point, tail vertebrae, tail spikes, a few plates and a femur had been exposed.
At the lower digsite on a rare rainy and cold day, we are working on excavating bones from a bone bed. The rock wall is part of the Morrison Formation that has been incised by a Tertiary stream channel at the top.
