Is this fossil a forgery? Answering that has polarized the paleontology world

The sun-scorched mines of Morocco’s Oulad Abdoun Basin are some of the richest fossil-hunting sites in the world.Laid down between 70 and 50 million years ago, the basin’s rocks are valued for their phosphate but also for preserving the remains of prehistoric marine life, including those of mosasaurs – large swimming reptiles that were contemporaries of Tyrannosaurus rex.Tens of millions of years later and thousands of kilometres away, the partial jawbone of one such creature has been the focus of a made-in-Canada dispute over whether or not the fossil is genuine.
