The “Jura” bit of the word “Jurassic,” as in Jurassic Park of movie megafame, is rooted in the Swiss canton of the same name. This weekend, in the town of Courtedoux, this will be the last chance to see some supremely impressive dinosaur tracks before they’re buried under bitumen. Crews start laying pavement for the new A16 motorway on Monday. Guided tours can be had both weekend days from 10 am through 7 pm. Susan Flory talks to Celine Fuchs, project manager of the dinosaur site Paleojura near the town of Courtedoux.
