HADROSAURUS OF THE UPPER CRETACEOUS NANAIMO GROUP
There are two main groups of Hadrosaurs, crested and non-crested. The bony crest on the top of the head of the hadrosaurs was hollow and attached to the nasal passages. It is thought that the hollow crest was used to make different sounds. These sounds may have signalled distress or been the mating calls used to attract mates. Given their size it would have made for quite the trumpeting sound.
This beautiful specimen graces the back galleries of the Courtenay and District Museum on Vancouver Island, British Columbia, Canada. I was very fortunate to have a tour this past summer with the deeply awesome Mike Trask joined by the lovely Lori Vesper. The museum houses an extensive collection of palaeontological and archaeological material found on Vancouver Island, many of which have been donated by the Vancouver Island Palaeontological Society.
Dan Bowen, Chair of the Vancouver Island Palaeontological Society, shared a photo of the first partly articulated dinosaur from Vancouver Island ever found. The research efforts of the VIPS run deep in British Columbia and this new very significant find is no exception. A Hadrosauroid dinosaur is a rare occurrence and further evidence of the terrestrial influence in the Upper Cretaceous, Nanaimo Group, Vancouver Island.
This fossil bone material was found years ago by Mike Trask of the Vancouver Island Palaeontological Society. You may recall that he was the same fellow who found the Courtenay elasmosaur. The bone was initially thought to be a plesiosaur but turned out to be a hadrosauroid. The find was confirmed by hadrosaur authority Dr. David Evans, senior curator of the Royal Ontario Museum.
You can see the articulated Hadrodauriod fossil bone Mike found now prepped fully prepped.
This fellow has kissing cousins over in the state of New Jersey where this species is the official state fossil. The first of his kind was found by John Estaugh Hopkins in New Jersey back in 1838.
