The Lomas Coloradas Formation is a Mesozoic geologic formation in Mexico. 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. Indeterminate hadrosaur remains, indeterminate ceratopsian remains, indeterminate tyrannosaur remains, indeterminate maniraptoriform remains, and indeterminate sauropod remains, most likely belonging to Alamosaurus, have been unearthed here.
