Taylor Publishes on Nature of Faunal Turnover, Change in Ocean Chemistry Associated with Latest Cambrian Mass Extinction
Professor Emeritus John Taylor and colleagues published a new study based on faunal collections from a 50-meter interval of the Jones Ridge Limestone in easternmost Alaska. The study provided new, detailed faunal range data across the base of the North American Ibexian Series and geochemical data that confirm an associated shift in ocean chemistry.
