Comment to pazos et al. (2019) “The oldest record of a tyreophoran track in Gondwana: Geological implications of subaerial exposure in the lower part of the Lajas Formation at the Covunco section (Neuquén Basin), Patagonia, Argentina

Abstract

The recent article published by Pazos et al. (2019) consists of adescription of one tyreophoran track in deltaic deposits of the MiddleJurassic Lajas Formation, Neuquén basin, Argentina. In their sedimentologicalinterpretation of the succession, the authors referred toseveral aspects of previous contributions (Zavala and González, 2001;Zavala, 2002; Canale et al., 2015), incurring in omissions and incorrectstatements that we consider should be clarified, in order to avoidgenerating confusion in one of the classic Lajas Formation section in theNeuquén basin.
