Excavation of British Columbia's First Complete Dinosaur (VI)
year of the hadrosaur excavation began in the first week of July after
weeks of poor weather which greatly shortened the time the field team had
to work on the site. The main objective for 2013 was to recover a femur
that was found the previous year at the end of the 2012 excavation season.
The palaeontologists also hoped for the opportunity to airlift the main
dinosaur jacket out of the site and get it back to the museum safely.
The main specimen was buried for the winter, but everything looked fine when the specimen was exhumed at the start of the 2013 field season.
While taking down overburden over the femur area PRPRC palaeontologist Lisa Buckley discovered the largest tyrannosaur tooth yet found at this site. There are only two or three teeth of adult tyrannosaurs found at this site to date out of a total of nearly sixty tyrannosaur teeth found so far. The rest of the tyrannosaur teeth are from juveniles.

Professor A. Guy Plint and his team from the University of Western Ontario analyse the geology of the dig site in order to reconstruct the palaeoenvironment and deduce the circumstances that caused the dinosaurs to be preserved at this site.
While the femur (>1m length) was being pedastaled, a second femur was found laying right against it. A third femur was discovered while trenching around the second femur, for a total of six discovered at the site to date. PRPRC palaeontologists have determined that this site is a hadrosaur bonebed. These two femora were collected and are currently being prepared at the PRPRC.
