“…The ichnological record of the Candeleros Formation in the Neuquén Province is well constrained to the border of the basin (easternmost outcrops), where several dinosaur track ichnotaxa are known from the west coast area of the Ezequiel Ramos Mexía dam, close to the El Chocón locality (Calvo and Rivera, 2018, and references therein). The theropod ichnospecies known from the Candeleros Formation include Abelichnus astigarrae Calvo, 1991, Bressanichnus patagonicus Calvo, 1991, Deferrariischnium mapuchensis Calvo, 1991, Picunichnus benedettoi Calvo, 1991 Candeleroichnus canalei Calvo and Rivera, 2018. To compare the degree of mesaxony using the same criteria sensu Lockley (2009), the AT l/w ratio was calculated for the five theropod ichnotaxa known from the Candeleros Formation, and the corresponding length and width AT values were obtained by measuring from the figures from Calvo and Rivera (2018;Figs. 3, 4, 7, 10 and 11).…”
