An exciting fossil find in southwest Saskatchewan -- a Prognathodon. Often called the 'T.rex of the sea' because of their massive skulls and teeth adapted for a mixture of cutting and crushing -- Prognathodons are mosasaurs. "We were pleasantly surprised to find most of the front of the skull was preserved, and additional bones are running into the hillside," RSM Palaeontologist Dr. Ryan McKellar said. "This new find is going to add another incredible piece to the Saskatchewan's provincial collection held at the RSM and we want to thank Parks Canada for their assistance in this amazing discovery."
