Then one day, in 1984, there was an exciting discovery: scientists had uncovered skin impressions and footprints from dinosaurs along the very same northern slope of the Colville River where Liscomb found his. With this in mind, the old bones were rapidly retrieved from their drawer – and revealed to have belonged to dinosaurs all along. This ignited a fierce debate among palaeontologists. Surely there couldn"t really have been cold-blooded animals this far north? Century-old assumptions were being called into question, and things were getting heated.
