Tracks may tell tale of reptilian land conquest

World Science for July 30, 2010 reported on tracks made by reptiles.

“At first life was re­strict­ed to coast­al swamps where lush rain­for­est ex­isted, full of gi­ant ferns and dra­gonflies. How­ev­er, when rep­tiles came on the scene they pushed back the fron­tiers, con­quering the dry con­ti­nen­tal in­te­ri­ors.”
