Abstract

In the Research News article “Mammal diversity takes a 20-million-year leap backwards” by Kim Peterson (24 May, p. 1102), the legend for the accompanying map contained two errors. The colors indicating “zhelestids” and ungulates were reversed, and the South American fossils, which are solely ungulates, were incorrectly represented as “zhelestids” and ungulates.
