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.
