Short summary
We measured the oxygen isotopic composition of Late Jurassic chondrichthyan teeth (sharks, rays, chimaeras) from the Swiss Jura to get ecological information. The main finding is that the extinct shark Asteracanthus (Hybodontiformes) could inhabit reduced salinity areas, although previous studies on other European localities always resulted in a clear marine isotopic signal for this genus. We propose a mainly marine ecology coupled with excursions into areas of lower salinity in our study site.
