Earth History, Ch. 181 Western U.S. orogenies

Earth History, Ch. 182 Late Cretaceous 75 Ma

Earth History, Ch. 183 K/T boundary 65 Ma

Earth History, Ch. 184 The Paleogene World Two-fold subdivision of Cenozoic: Paleogene, Neogene Previously, Cenozoic was divided into Tertiary (Paleocene-Pliocene) and Quaternary (Pleistocene- Holocene) Know periods and epochs! Cenozoic Paleogene Neogene Paleocene Eocene Oligocene Miocene Pliocene Holocene Pleistocene 65 24

Earth History, Ch. 185 Paleogene life In marine realm, most groups that survived end-Cretaceous mass extinction recovered and diversified during Paleogene –Planktonic forams, calcareous nannos, mollusks, arthropods Demise of giant marine reptiles opened the door to whales (Eocene) and giant sharks!

Earth History, Ch. 186 Whale evolution (Eocene-Holocene) Terrestrial ancestor Large, marine forms

Earth History, Ch. 187

8 Giant Eocene shark Modern shark jaws

Earth History, Ch. 189 Paleogene life Other interesting newcomers to marine or marginal marine habitats: –Penguins –Pinnipeds (seals, sea lions, walruses)

Earth History, Ch Paleogene life On land………….. –Diversification and “modernization” of angiosperms –By early Oligocene time, half of all angiosperm genera were ones that still exist today Origin of grasses –Earliest forms were sedge-like (discontinuous growth) –Late Oligocene-Neogene forms capable of continuous growth (able to withstand grazing pressure)

Earth History, Ch Paleogene life Explosive adaptive radiation of mammals! –By Eocene time, most modern orders of mammals had appeared, including primates, carnivores and horses Cantius, climbing around in our family tree!

Earth History, Ch. 1812

Earth History, Ch. 1813

Earth History, Ch Eocene fossil bat

Earth History, Ch Hyracotherium (“Eohippus”) earliest horse Dog-sized 4 toes 3 toes

Earth History, Ch. 1816

Earth History, Ch Diacodexis (early even-toed ungulate)

Earth History, Ch Eocene elephants

Earth History, Ch Diatryma (a top predator--stay away from this turkey!) 8 ft

Earth History, Ch. 1820

Earth History, Ch Paleogene life Oligocene was noteworthy for: –Paraceratherium, largest land mammal ever (member of rhino family) –Origin of true monkeys –Expansion of big cats

Earth History, Ch Paraceratherium 18 ft at shoulder

Earth History, Ch Aegyptopithecus (Oligocene monkey)

Earth History, Ch Dinictis (Oligocene saber-tooth cat)

Earth History, Ch Oligocene mammalian fauna of Nebraska & South Dakota

Earth History, Ch Paleogene life Many groups of mammals became extinct during Eocene time or at the Eocene— Oligocene boundary Climate change probably is responsible for extinctions

Earth History, Ch. 1827

Earth History, Ch Paleogene paleogeography and climate Beginning in late Eocene, climate rapidly became cooler and drier –Relatively heavy oxygen isotope ratios (consistent with growth of continental glaciers) –Establishment of circum-polar currents around Antarctica

Earth History, Ch Evidence for climate change

Earth History, Ch Antarctic circumpolar current SA ANT AU

Earth History, Ch Continued break-up of Pangaea
