Pine River Area

Ankylosaur trackslab with an interesting history

The first reported footprint finds in the Dunvegan Formation were from the Pine River area near Chetwynd, British Columbia (Storer, 1975; Currie, 1989).  Several loose footprint blocks have been found eroding out of the banks along rivers and creeks in the area.  Most of these blocks are infillings of tracks or natural casts.  The original track-bearing substrate is often too soft and friable to withstand exposure for any duration while the hard sandstone infilling the original tracks are very resistant to the process of erosion and thus are the most common type of footprint preservation found in this area.

Recent research in this area was the product of a collaboration between Dr. A. Guy Plint (University of Northwestern Ontario), who recognized the tracks during the course of his extensive geological research in the area, and Richard T. McCrea (Ph.D. student at the University of Alberta).  This collaboration started with a three day field trip in the summer of 1999 some of the results of which were incorporated into an undergraduate thesis (Scott, 2000).  A great deal of data was collected during consecutive field seasons.  A diverse vertebrate ichnofauna was recognized, which was dominated by ankylosaur tracks (Tetrapodosaurus ichnsp.).  Research on the tracks of the Pine River area continues.
