Excavation of British Columbia's First Complete Dinosaur (IV)


Season four of the hadrosaur excavation began in late June. PRPRC palaeontologists and staff had just set up the site and camp when the region was hit with intense and prolonged rains that ultimately closed two of the three roads in to Tumbler Ridge, and swept away an entire bridge. This weather adversely affected all palaeontological projects in western Canada and it reduced the several weeks of planned digging at the hadrosaur site to only a little over two weeks. The palaeontologists had hoped to pedastal, jacket and remove the articulated specimen this summer, but now there was too little time. Still, there was much to do to get the specimen ready for removal, possibly for next year's excavation.

 

A small vertebra was one of the early finds for this season.

 

The pit towards the end of July.

 

The rocks could sometimes give palaeontologists clues that they were getting close to fossil bones with brightly coloured rocks like this. It is possible that these coloured lines are oxides of iron (rust) produced from the decay of the dinosaur as these types of rocks were often found in close proximity to bone, sometimes even encasing bone.

 

A small fibula (smallest of the paired bones of the lower leg) found in between the proximal end of the tail and ischium of the hadrosaur. The fibula is laying on the lower surface of the bone-bearing layer. This bone was too small to be the fibula from the main hadrosaur specimen, opening up the possibility that there could be more dinosaurs at this site.
