EVOLUTION Correction for “Ecomorphological diversification in squamates from conserved pattern of cranial integration,” by Akinobu Watanabe, Anne-Claire Fabre, Ryan N. Felice, Jessica A. Maisano, Johannes Müller, Anthony Herrel, and Anjali Goswami, which was first published July 1, 2019; 10.1073/pnas.1820967116 (Proc. Natl. Acad. Sci. U.S.A. 116, 14688–14697). The authors note that the interpretation of the ancestral snake locomotion and habitat has been altered from nonfossorial in the original article to nonaquatic due to the resemblance of ancestral snake skull shape to a semifossorial taxon. Accordingly, the statements that require modification include, in the Abstract, line 22, “terrestrial, nonfossorial” should instead appear as “nonaquatic”; on page 14692, right column, first full paragraph, line 14, “terrestrial” should instead appear as “semifossorial”; on page 14694, left column, second full paragraph, lines 19–20, “nonfossorial, terrestrial” should instead appear as “nonaquatic”; and on page 14695, right column, first full paragraph, line 12, “terrestrial, nonburrowing” should instead appear as “nonaquatic.”
