# The Younger Dryas impact hypothesis: a cosmic catastrophe

Vance T. Holliday, Todd Surovell, David J. Meltzer et al., 2014. _Journal of Quaternary Science 29(6), 515–530_.

Review concluding that no crater is known, age control is weak at 26 of 29 localities, replication has failed, extinctions were staggered, and archaeological data show no population decline at 12.9 ka.
