Geologic formation in Argentina
The Coli Toro Formation is a Maastrichtian -Danian geological formation in Argentina . Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus .[ 1]
The formation in later publications has been reassigned as the Coli Toro Member at the basal levels of the Los Alamitos Formation , containing fossil remains of Sulcusuchus erraini [ 2] Angostura Colorada Formation .[ 3]
