They argued that these data provide a “critical link toward our understanding of the correlation between siliciclastic-dominated and carbonate-dominated Precambrian-Cambrian transition sections.” Here, I challenge this conclusion and point out errors and omissions. 1. Omission. The critical importance Corsetti and Hagadorn ascribe to their δ13C data derives from their repeated assertion that “the Death Valley section is one of two boundary sections known to contain the index fossil Treptichnus (Phycodes) pedum and carbonate carbon-derived isotope excursions bracketing the Precambrian-Cambrian boundary.”...
