“…For example, because a researcher cannot always choose the location or orientation for consumptive sampling, they often have to calculate mean VEIW from one region of the tooth and apply these data to different transect locations within the same tooth ( Erickson, 1992 , 1996b ; Sereno et al, 2007 ; Gren, 2011 ; D’Emic et al, 2013 , 2019 ; Gren & Lindgren, 2013 ; Garcia & Zurriaguz, 2016 ; Kear et al, 2017 ; Ricart et al, 2019 ). Likewise, researchers may have to calculate mean VIEW from one tooth position within the jaw and then apply these values to other tooth positions ( Kosch, 2014 ; Schwarz et al, 2015 ; Garcia & Zurriaguz, 2016 ; D’Emic & Carrano, 2019 ; D’Emic et al, 2019 ). Moreover, because von Ebner lines are not always visible along the entire transect, mean VEIWs are typically derived from a transect subsample, as opposed to being calculated from the entire transect length ( Erickson, 1992 , 1996a , 1996b ; Gren, 2011 ; Gren & Lindgren, 2013 ; Button et al, 2017 ; Erickson et al, 2017 ; Kear et al, 2017 ; Ricart et al, 2019 ; D’Emic et al, 2019 ).…”
