As summer is fast approaching, we are excited fieldwork will be resuming soon enough. Being #FossilFriday, we thought it fitting to showcase some of the earlier work done at Pipestone Creek Bonebed by the Royal Tyrrell field crews circa 1986.

Over the years, it became common practice to nickname Pipestone Creek bonebed skulls to distinguish them as there were many. Following that practice, Darren Tanke had nicknamed this skull Cybill after his then 1980s celebrity crush Cybill Shepard.

Picture 2: After excavating Cybill and encasing it in a thick-layered plaster jacket, palaeontologists were faced with the difficult task, transporting the heavy skull from the field to a lab where it could be prepared and studied. In 1986, a bridge across Pipestone Creek to the bonebed had not yet been built. Instead, the team had to load up the field jacket onto an 8×8 Argo. The all-terrain amphibious vehicle safely maneuvered the difficult ground, moving the skull from the quarry through the creek bed to a nearby truck where it was loaded into the back. Today, the important holotype specimen ofย ๐‘ƒ๐‘Ž๐‘โ„Ž๐‘ฆ๐‘Ÿโ„Ž๐‘–๐‘›๐‘œ๐‘ ๐‘Ž๐‘ข๐‘Ÿ๐‘ข๐‘ ย ๐‘™๐‘Ž๐‘˜๐‘ข๐‘ ๐‘ก๐‘Ž๐‘–ย resides at the Royal Tyrrell Museum in their collection.ย
