Western Alberta


A large trackslab with skin impressions was found near the town of Dunvegan, Alberta by local residents.  The slab (TMP 94.183.1) was collected by Darren Tanke with the help of locals and was taken to the Royal Tyrrell Museum of Palaeontology in Drumheller, Alberta.

The slab was put safely in storage at the museum, but was not studied for many years.  The trackway was obviously made by a large quadruped (one complete foot and hand print and one partial footprint), but it was a bit unusual looking since it appeared to only have three digit impressions on the footprints, while the handprint had the expected five digit impressions.  It was not until the trackway was examined under optimal lighting conditions that a much reduced inner digit was found on the footprint.  The discovery of the digit and the proportion of the handprint in relation to the footprint showed that the trackway was that of an ankylosaur (McCrea et al., 1998; McCrea et al., 2001).

Recent research trips to other sites in this region have yielded additional footprint material, mainly ankylosaur prints.
