Paleobotany: Study of fossil plants; traditionally includes the study of fossil algae and fungi in addition to land plants.

Vertebrate Paleontology: Study of vertebrate fossils, from primitive fishes to mammals.The date for Grand Canyon started off older than 70 Ma.Then the western and central portions of the Canyon were dated as 5 to 6 Ma old—a date always uncomfortable with uniformitarian scientists since it implied rapid erosion within their paradigm. One dating technique discovered that the western Canyon was about 17 Ma old.Another found that the western and central portions are 55 to 65 Ma old.Those who believe that the canyon is only 5 to 6 Ma claim these new dating methods are flawed, while the advocates of the new dating techniques claim the opposite.
