  • ABSTRACT A tetrapod-based biochronologic framework for the terrestrial Triassic, which subdivides the Triassic into eight ‘Land Vertebrate Faunachrons’ (LVFs), has been proposed and developed by Lucas and coworkers. In a recent article, these authors reiterated their support for this scheme and used this opportunity to respond to criticisms dealing with the validity and utility of Triassic LVFs. This article is a reply to Lucas and colleagues and demonstrates that many aspects of this Triassic… CONTINUE READING
