Pleistocene Epoch - Florida Fossils: Evolution of Life and Land
This video from the Museum's Florida Fossils exhibit describes the Pleistocene Epoch, 2 million to 10,000 years ago. The Ice Ages of the Pleistocene wreaked climatic havoc on the northern continents, but Florida was buffered from the worst effects by the warm waters of the Gulf of Mexico. Nevertheless, rapid pulses of climate change profoundly affected the area. During glacial periods (low sea levels), Florida was more than twice as large as it is today. Warmer periods (high sea levels) caused the peninsula to shrink in size.
The number of larger animals (megafauna) declined during the late Pleistocene, but scientists are unsure why these extinctions occurred. Changing climates or disease may have caused their demise. Perhaps the new predator in the region, Homo sapiens, hunted these marvelous animals to extinction. All we know with confidence is that their fossilized remains testify to their existence in Florida until about 10,000 years ago.

Paul S. Martin, Pleistocene Ecologist: Colleagues Honor His Legacy, 2011
Seven science colleagues present tributes to Paul S. Martin, 1928 - 2010: Jim King, Geoff Spaulding, Gary Haynes, Alberto Burquez, Tom Van Devender, David Burney, and Connie Barlow (plus, Paul's son, Tom Martin). The outdoor memorial service was held on the University of Arizona's Tumamoc Hill (Tucson) on 12 November 2011. Pleistocene ecology and other topics discussed include: palynology, packrat middens as a chronological source of fossil pollen data, megafaunal extinctions of the Quaternary, the Overkill hypothesis, natural history of the Southwestern USA and northern Mexico, Rio Mayo plants, neotropical anachronisms (and the fruits the gomphotheres ate), Pleistocene Rewilding, and the Mammoth Memorial Service at the Mammoth Site in South Dakota. Closing hymn: "Bring Back the Elephants." Each tribute begins at these times:
Tom Martin "Childhood Memories" (0:44)
Jim King "The Pollen Years" (7:31)
Geoff Spaulding "Packrat Middens and Pleistocene Vegetation" (15:47)
Gary Haynes "Overkill and Pleistocene Extinctions" (19:27)
Alberto Burquez "Rio Mayo Plants" (22:38)
Tom Van Devender "Natural History of the Southwest" (30:00)
David Burney "Pleistocene Rewilding" (35:00)
Connie Barlow "Bring Back the Elephants" (45:36)

Paul S. Martin, Pleistocene ecologist, 1928 - 2010
Paul S. Martin was interviewed by Connie Barlow in 1997. In this short extract, Martin muses on "Pleistocene Rewilding," which entails re-populating select habitats in western USA with living proxies for extinct Ice Age mammals. Proxies would include elephants for mammoths, African lions for the extinct American plains lion, the African cheetah for the extinct American cheetah, living camels for the extinct American camel, horses for the extinct native horses, and rhinoceros for extinct ground sloths.
Two years after this interview, Martin published an advocacy essay, "Bring Back the Elephants!" in Wild Earth magazine. In 2005, Paul S. Martin was one of a dozen authors of the advocacy commentary (published in Nature) "Rewilding North America." And in 2006, the same authors wrote a longer piece for American Naturalist, titled, "Pleistocene Rewilding."

Abstract
The extent to which past climate change has dictated the pattern and timing of the out-of-Africa expansion by anatomically modern humans is currently unclear [Stewart JR, Stringer CB (2012) Science 335:1317--1321 - Human Evolution Out of Africa: The Role of Refugia and Climate Change - http://www.sciencemag.org/content/335/6074/1317.abstract]. In particular, the incompleteness of the fossil record makes it difficult to quantify the effect of climate. Here, we take a different approach to this problem; rather than relying on the appearance of fossils or archaeological evidence to determine arrival times in different parts of the world, we use patterns of genetic variation in modern human populations to determine the plausibility of past demographic parameters. We develop a spatially explicit model of the expansion of anatomically modern humans and use climate reconstructions over the past 120 ky based on the Hadley Centre global climate model HadCM3 to quantify the possible effects of climate on human demography. The combinations of demographic parameters compatible with the current genetic makeup of worldwide populations indicate a clear effect of climate on past population densities. Our estimates of this effect, based on population genetics, capture the observed relationship between current climate and population density in modern hunter--gatherers worldwide, providing supporting evidence for the realism of our approach. Furthermore, although we did not use any archaeological and anthropological data to inform the model, the arrival times in different continents predicted by our model are also broadly consistent with the fossil and archaeological records. Our framework provides the most accurate spatiotemporal reconstruction of human demographic history available at present and will allow for a greater integration of genetic and archaeological evidence.

Woolly Rhino Fossil w/ Xiaoming Wang
http://www.nhm.org/site/research-collections/vertebrate-paleontology/staff-biographies/wang
August 28, 2011 --A paper to be published on September 2, 2011 in the authoritative magazine Science reveals the discovery of a primitive woolly rhino fossil in the Himalayas, which suggests some giant mammals first evolved in present-day Tibet before the beginning of the Ice Age. The extinction of Ice Age giants such as woolly mammoths and rhinos, giant sloths, and saber-tooth cats has been widely studied, but much less is known about where these giants came from, and how they acquired their adaptations for living in a cold environment.
A team of geologists and paleontologists led by Xiaoming Wang from the Natural History Museum of Los Angeles County (NHM) and Qiang Li of Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, uncovered a complete skull and lower jaw of a new species of woolly rhino (Coelodonta thibetana) in 2007, at the foothills of the Himalayas in southwestern Tibetan Plateau.
"Cold places, such as Tibet, Arctic, and Antarctic, are where the most unexpected discoveries will be made in the future — these are the remaining frontiers that are still largely unexplored," said the NHM's Dr. Wang.
There are dual connections between the new paper and the Natural History Family of Museums (including the Natural History Museum and the Page Museum at the La Brea Tar Pits). Dr. Wang contributed to NHM's Age of Mammals exhibition, which depicts the creation of the Himalayan Mountains and Tibetan Plateau, and subsequent climactic changes of the Pleistocene Ice Age. Additionally, the largest Ice Age megafauna collection in the world is excavated, researched, and displayed at the Page Museum.
The new rhino is 3.6 million years old (middle Pliocene), much older and more primitive than its Ice Age (Pleistocene) descendants in the mammoth steppes across much of Europe and Asia. The extinct animal had developed special adaptations for sweeping snow using its flattened horn to reveal vegetation, a useful behavior for survival in the harsh Tibetan climate. These rhinos lived at a time when global climate was much warmer and the northern continents were free of the massive ice sheets seen in the Ice Age later.
The rhino accustomed itself to cold conditions in high elevations and became pre-adapted for the future Ice Age climate. When the Ice Age eventually arrived around 2.6 million years ago, the new paper posits, the cold-loving rhinos simply descended from the high mountains and began to expand throughout northern Asia and Europe.
In addition to the new woolly rhino, the paleontologist team also uncovered extinct species of three-toed horse (Hipparion), Tibetan bharal (Pseudois, also known as blue sheep), chiru (Pantholops, also known as Tibetan antelope), snow leopard (Uncia), badger (Meles), as well as 23 other kinds of mammals.
The team's new fossil assemblage from Tibet offers new insights into the origin of the cold-adapted Pleistocene megafauna, which has usually been sought either in the arctic tundra or in the cold steppes elsewhere. This new evidence offers an alternative scenario: the harsh winters of the rising Tibetan Plateau may have provided the initial step towards cold-adaptation for several subsequently successful members of the late Pleistocene mammoth fauna in Europe, Asia, and to a lesser extent, North America. The Tibetan Plateau may have been another cradle of the Ice Age giants.
"This discovery clarifies the origin of the woolly rhinoceros — and perhaps much of the now extinct, cold-adapted, Pleistocene Eurasian megafauna — as the high-altitude environments of the Zanda Basin of the primordial Pliocene Himalayas," said H. Richard Lane of the National Science Foundation (NSF)'s Division of Earth Sciences.
