Open Thesis Final V2.Pdf
The Pennsylvania State University The Graduate School Department of the Geosciences TAXONOMIC AND ECOLOGIC IMPLICATIONS OF MAMMOTH MOLAR MORPHOLOGY AS MEASURED VIA COMPUTED TOMOGRAPHY A Thesis in Geosciences by Gregory J Smith 2015 Gregory J Smith Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science August 2015 ii The thesis of Gregory J Smith was reviewed and approved* by the following: Russell W. Graham EMS Museum Director and Professor of the Geosciences Thesis Advisor Mark Patzkowsky Professor of the Geosciences Eric Post Director of the Polar Center and Professor of Biology Timothy Ryan Associate Professor of Anthropology and Information Sciences and Technology Michael Arthur Professor of the Geosciences Interim Associate Head for Graduate Programs and Research *Signatures are on file in the Graduate School iii ABSTRACT Two Late Pleistocene species of Mammuthus, M. columbi and M. primigenius, prove difficult to identify on the basis of their third molar (M3) morphology alone due to the effects of dental wear. A newly-erupted, relatively unworn M3 exhibits drastically different characters than that tooth would after a lifetime of wear. On a highly-worn molar, the lophs that comprise the occlusal surface are more broadly spaced and the enamel ridges thicken in comparison to these respective characters on an unworn molar. Since Mammuthus taxonomy depends on the lamellar frequency (# of lophs/decimeter of occlusal surface) and enamel thickness of the third molar, given the effects of wear it becomes apparent that these taxonomic characters are variable throughout the tooth’s life. Therefore, employing static taxonomic identifications that are based on dynamic attributes is a fundamentally flawed practice. -
Teacher Guide: Meet the Proboscideans
Teacher Guide: Meet the Proboscideans Concepts: • Living and extinct animals can be classified by their physical traits into families and species. • We can often infer what animals eat by the size and shape of their teeth. Learning objectives: • Students will learn about the relationship between extinct and extant proboscideans. • Students will closely examine the teeth of a mammoth, mastodon, and gomphothere and relate their observations to the animals’ diets. They will also contrast a human’s jaw and teeth to a mammoth’s. This is an excellent example of the principle of “form fits function” that occurs throughout biology. TEKS: Grade 5 § 112.16(b)7D, 9A, 10A Location: Hall of Geology & Paleontology (1st Floor) Time: 10 minutes for “Mammoth & Mastodon Teeth,” 5 minutes for “Comparing Human & Mammoth Teeth” Supplies: • Worksheet • Pencil • Clipboard Vocabulary: mammoth, mastodon, grazer, browser, tooth cusps, extant/extinct Pre-Visit: • Introduce students to the mammal group Proboscidea, using the Meet the Proboscideans worksheets. • Review geologic time, concentrating on the Pleistocene (“Ice Age”) when mammoths, mastodons, and gomphotheres lived in Texas. • Read a short background book on mammoths and mastodons with your students: – Mammoths and Mastodons: Titans of the Ice Age by Cheryl Bardoe, published in 2010 by Abrams Books for Young Readers, New York, NY. Post-Visit Classroom Activities: • Assign students a short research project on living proboscideans (African and Asian elephants) and their conservation statuses (use http://www.iucnredlist.org/). Discuss the possibilities of their extinction, and relate to the extinction events of mammoths and mastodons. Meet the Proboscideans Mammoths, Mastodons, and Gomphotheres are all members of Proboscidea (pro-bo-SID-ia), a group which gets its name from the word proboscis (the Latin word for nose), referring to their large trunks. -

Distinguishing Extant Elephants Ivory from Mammoth Ivory Using a Short
www.nature.com/scientificreports OPEN Distinguishing extant elephants ivory from mammoth ivory using a short sequence of cytochrome b gene Jacob Njaramba Ngatia1, Tian Ming Lan2,3,4, Yue Ma1,5, Thi Dao Dinh1, Zhen Wang1,5, Thomas D. Dahmer6 & Yan Chun Xu1,5,7* Trade in ivory from extant elephant species namely Asian elephant (Elephas maximus), African savanna elephant (Loxodonta africana) and African forest elephant (Loxodonta cyclotis) is regulated internationally, while the trade in ivory from extinct species of Elephantidae, including woolly mammoth, is unregulated. This distinction creates opportunity for laundering and trading elephant ivory as mammoth ivory. The existing morphological and molecular genetics methods do not reliably distinguish the source of ivory items that lack clear identifcation characteristics or for which the quality of extracted DNA cannot support amplifcation of large gene fragments. We present a PCR-sequencing method based on 116 bp target sequence of the cytochrome b gene to specifcally amplify elephantid DNA while simultaneously excluding non-elephantid species and ivory substitutes, and while avoiding contamination by human DNA. The partial Cytochrome b gene sequence enabled accurate association of ivory samples with their species of origin for all three extant elephants and from mammoth. The detection limit of the PCR system was as low as 10 copy numbers of target DNA. The amplifcation and sequencing success reached 96.7% for woolly mammoth ivory and 100% for African savanna elephant and African forest elephant ivory. This is the frst validated method for distinguishing elephant from mammoth ivory and it provides forensic support for investigation of ivory laundering cases. -
Straight-Tusked Elephant (Palaeoloxodon Antiquus) and Other Megafauna in Europe

Late Quaternary Extinctions on California's
Flightless ducks, giant mice and pygmy mammoths: Late Quaternary extinctions on California’s Channel Islands Torben C. Rick, Courtney A. Hofman, Todd J. Braje, Jesu´ s E. Maldonado, T. Scott Sillett, Kevin Danchisko and Jon M. Erlandson Abstract Explanations for the extinction of Late Quaternary megafauna are heavily debated, ranging from human overkill to climate change, disease and extraterrestrial impacts. Synthesis and analysis of Late Quaternary animal extinctions on California’s Channel Islands suggest that, despite supporting Native American populations for some 13,000 years, few mammal, bird or other species are known to have gone extinct during the prehistoric human era, and most of these coexisted with humans for several millennia. Our analysis provides insight into the nature and variability of Quaternary extinctions on islands and a broader context for understanding ancient extinctions in North America. Keywords Megafauna; island ecology; human-environmental interactions; overkill; climate change. Downloaded by [Torben C. Rick] at 03:56 22 February 2012 Introduction In earth’s history there have been five mass extinctions – the Ordovician, Devonian, Permian, Triassic and Cretaceous events – characterized by a loss of over 75 per cent of species in a short geological time period (e.g. 2 million years or less: Barnosky et al. 2011). Although not a mass extinction, one of the most heavily debated extinction events is the Late Quaternary extinction of megafauna, when some two-thirds of large terrestrial mammalian genera (444kg) worldwide went extinct (Barnosky et al. 2004). Explanations for this event include climate change, as the planet went from a glacial to interglacial World Archaeology Vol. -
The Woolly Mammoth
The Woolly Mammoth The Woolly Mammoth by Edward I. Maxwell The closest relative of the woolly mammoth is the Asian elephant. The main difference between the two is that the mammoth had an incredible coat of fur, made up of an outer layer of coarse "guard hair" with an inner layer of curly wool. The last known group of mammoths died off, or became extinct, around 4,000 years ago. The mammoth roamed the northern lands of the world during a period known as the Ice Age. It was among the largest land mammals to roam the earth. The mammoth was a tough beast and was able to endure extreme weather conditions and frigid temperatures. The mammoth shared these northern territories with other mammals during the Ice Age. The most important mammal to interact with the mammoth, however, was the human. When the mammoths were at their greatest numbers, humans mainly hunted animals and foraged for food. These hunters would follow herds of animals over incredibly long distances in order to hunt them. The woolly mammoth provided a great amount of food and other important things for these humans. The fur, for example, could be used to make coats and blankets that would help keep out the cold in the icy environment. Bones from the mammoth could be used to make tools and weapons. Because one mammoth provided so many useful things to a large group of people, early humans would follow the herds wherever they went. There is even a theory that the humans followed the mammoth over a land-bridge from Asia into the Americas. -

Columbian Mammoths: Giants of the Ice Age
Name: __________________________________________________ Date: ______________ Columbian Mammoths: Giants of the Ice Age Did you know not all mammoths were woolly mammoths? The woolly mammoth was just one of nearly a dozen different species of mammoths. Another species was the Columbian (pronounced “cuh-LUM-be-un”) mammoth. Columbian mammoths lived during the Pleistocene Epoch (“PLY-stuh-SEEN EP-uck”), sometimes called the Ice Age. The Pleistocene Epoch started 2.5 million years ago and ended about 10,000 years ago. Even though people call it the Ice Age, not all the world was covered in ice. Sheets of ice called glaciers (“GLAY-shurs”) covered most of what is now Canada and the northern United States, but the lands that became the southern United States and Mexico were not under ice. Columbian mammoths were grazers, or animals that eat mostly grass. To make sure they had enough to eat, they lived in savannas (“suh-VAN-uhs”). Savannas are warm grasslands with scattered trees, and they were away from the glaciers. This was different from the woolly mammoths, which lived closer to the glaciers in lands called steppes (“STEPS”), cool plains with shrubs, herbs, and a little grass. How big was a Columbian mammoth? Huge! They were about 14 feet tall, or 4.3 meters. They also weighed as much as 10 tons, the same as a school bus. This made them much bigger than woolly mammoths, which were about 10 feet tall (3 meters) and weighed 6 tons. So why were they called Columbian mammoths? Scientists use New Latin to name animals. In New Latin, “Columbia” means “land of Columbus”, or North America. -

^ \ . I I ^ I !* A 5,^' ; WACO 'The nation's first and only recorded discovery of a nursery herd of Pleistocene mammoths' - National Park Service MAMMOTH SITE WACO MAMMOTH SITE OVERVIEW • The Waco AAommoth Site sits In more than 100 acres of wooded parkland and is the result of a collabo ration between the City of Waco, Baylor University, and the Waco AAommoth Foundation. The City of Waco manages the site, while Baylor University's AAayborn AAuseum Complex curates the excavated mate rial and oversees scientific research. • Congressional legislation is currently pending to create the Waco Mammoth National Monument and to include the site as a unit of the Notional Park Service. • The Waco Mammoth Site was first discovered in 1978. The site is the only known discovery of a nursery herd (female mammoths and their offspring) in North America. This is also North America's largest known collection of Columbian mammoths that died in a single event. • Research indicates the Waco mammoths perished in a series of flood-related events spread across thou sands of years. One of the earliest events took place approximately 68,000 years ago and included 19 of the mammoths. • To date, 24 mammoths have been discovered, and the likelihood of additional fossils exists. A large por tion of the mammoth remains were discovered in the ravine outside of the dig shelter. COLUMBIAN MAMMOTH FACTS • Columbian Mammoths (Mommuthus columbi) lived during the Pleisto cene Epoch (2.5 million years to 10,000 yeors ago). • The Columbian mammoth was one of the largest mammals to have lived during the Pleistocene Epoch. -
