The Lomas Coloradas Formation is a Mesozoic geologic formation in Mexico.^[1]^[2]^[3]^[4] Dinosaur remains are among the fossils that have been recovered from the formation, although only a few have yet been referred to a specific genus.^[5] Indeterminate hadrosaur remains,^[6] indeterminate ceratopsian remains,^[7] indeterminate tyrannosaur remains,^[8] indeterminate maniraptoriform remains,^[9] and indeterminate sauropod remains, most likely belonging to Alamosaurus, have been unearthed here.^[10]
