Abstract

The recent article by Israde-Alcántara et al. (1) outlined a wide array of purported impact proxies from a lacustrine paleo-record in Lake Cuitzeo, Mexico. These findings were used to support the suggestion of a Younger Dryas (YD) impact event/s. Although most of the purported impact proxies have been described in previous publications (2, 3), this new work extended the range of such markers to Mexico. The article also allowed the proponents of the YD Impact Hypothesis [YDIH] to respond to the many critiques of the YDIH.
