Alpine Ibex, Capra Ibex
(CAPRA IBEX) ALPINE IBEX by: Braden Stremcha EVOLUTION Alpine ibex is part of the Bovidae family under the order Artiodactyla. The Capra genus signifies this species specifically as a wild goat, but this genus shares very similar evolutionary features as species we recognize in Montana like Oreamnos (mountain goat) and Ovis (sheep). Capra, Oreamnos, and Ovis most likely derived in evolution from each other due to glacial migration and failure to hybridize between genera and species.Capra ibex was first historically observed throughout the central Alpine Range of Europe, then was decreased to Grand Paradiso National Park in Italy and the Maurienne Valley in France but has since been reintroduced in multiple other countries across the Alps. FORM AND FUNCTION Capra ibex shares a typical hoofed unguligrade foot posture, a cannon bone with raised calcaneus, and the common cursorial locomotion associated with species in Artiodactyla. These features allow the alpine ibex to maneuver through the steep terrain in which they reside. Specifically, for alpine ungulates and the alpine ibex, more energy is put into balance and strength to stay on uneven terrain than moving long distances. Alpine ibexes are often observed climbing artificial dams that are almost vertical to lick mineral deposits! This example shows how efficient Capra ibex is at navigating steep and dangerous terrain. The most visual distinction that sets the Capra genus apart from others is the large, elongated semicircular horns. Alpine ibex specifically has horns that grow throughout their life span at an average of 80mm per year in males. When winter comes around this growth is stunted until spring and creates an obvious ring on the horn that signifies that year’s overall growth. -
Evolution and Extinction of the Giant Rhinoceros Elasmotherium Sibiricum Sheds Light on Late Quaternary Megafaunal Extinctions
ARTICLES https://doi.org/10.1038/s41559-018-0722-0 Evolution and extinction of the giant rhinoceros Elasmotherium sibiricum sheds light on late Quaternary megafaunal extinctions Pavel Kosintsev1, Kieren J. Mitchell2, Thibaut Devièse3, Johannes van der Plicht4,5, Margot Kuitems4,5, Ekaterina Petrova6, Alexei Tikhonov6, Thomas Higham3, Daniel Comeskey3, Chris Turney7,8, Alan Cooper 2, Thijs van Kolfschoten5, Anthony J. Stuart9 and Adrian M. Lister 10* Understanding extinction events requires an unbiased record of the chronology and ecology of victims and survivors. The rhi- noceros Elasmotherium sibiricum, known as the ‘Siberian unicorn’, was believed to have gone extinct around 200,000 years ago—well before the late Quaternary megafaunal extinction event. However, no absolute dating, genetic analysis or quantita- tive ecological assessment of this species has been undertaken. Here, we show, by accelerator mass spectrometry radiocarbon dating of 23 individuals, including cross-validation by compound-specific analysis, that E. sibiricum survived in Eastern Europe and Central Asia until at least 39,000 years ago, corroborating a wave of megafaunal turnover before the Last Glacial Maximum in Eurasia, in addition to the better-known late-glacial event. Stable isotope data indicate a dry steppe niche for E. sibiricum and, together with morphology, a highly specialized diet that probably contributed to its extinction. We further demonstrate, with DNA sequencing data, a very deep phylogenetic split between the subfamilies Elasmotheriinae and Rhinocerotinae that includes all the living rhinoceroses, settling a debate based on fossil evidence and confirming that the two lineages had diverged by the Eocene. As the last surviving member of the Elasmotheriinae, the demise of the ‘Siberian unicorn’ marked the extinction of this subfamily. -

Distinguishing Quaternary Glyptodontine Cingulates in South America: How Informative Are Juvenile Specimens?
Distinguishing Quaternary glyptodontine cingulates in South America: How informative are juvenile specimens? CARLOS A. LUNA, IGNACIO A. CERDA, ALFREDO E. ZURITA, ROMINA GONZALEZ, M. CECILIA PRIETO, DIMILA MOTHÉ, and LEONARDO S. AVILLA Luna, C.A., Cerda, I.A., Zurita, A.E., Gonzalez, R., Prieto, M.C., Mothé, D., and Avilla, L.S. 2018. Distinguishing Quaternary glyptodontine cingulates in South America: How informative are juvenile specimens? Acta Palaeontologica Polonica 63 (1): 159–170. The subfamily Glyptodontinae (Xenarthra, Cingulata) comprises one of the most frequently recorded glyptodontids in South America. Recently, the North American genus Glyptotherium was recorded in South America, in addition to the genus Glyptodon. It has been shown that both genera shared the same geographic distribution in central-north and eastern areas of South America (Venezuela and Brazil, respectively). Although some characters allow differentiation between adult specimens of both genera, the morphological distinction between these two genera is rather difficult in juvenile specimens. In this contribution, a detailed morphological, morphometric and histological survey of a juvenile specimen of Glyptodontinae recovered from the Late Pleistocene of northern Brazil is performed. The relative lower osteoderms thickness, the particular morphology of the annular and radial sulci and the distal osseous projections of the caudal osteoderms suggest that the specimen belongs to the genus Glyptotherium. In addition, the validity of some statistical tools to distinguish between different ontogenetic stages and in some cases between genera is verified. The osteoderm microstructure of this juvenile individual is characterized by being composed of a cancellous internal core surrounded by a compact bone cortex. Primary bone tissue mostly consists of highly vascularized, woven-fibered bone tissue. -

Read each section and complete the tasks. DO NOT EDIT--Changes must be made through “File info” CorrectionKey=CA-B FIGURE 1: This creosote ring in the Mojave Desert is estimated to be 11 700 years old . This makes it one of the oldest living organisms on Earth . The creosote bush is thought to be the most drought-tolerant plant in North America. It has a variety of adaptations to its desert environment, including its reproductive tendency to clone outward in rings rather than rely solely on seed production. The plant’s leaves are coated in a foul-tasting resin that protects it from water loss through evaporation and from grazing. It only opens its stomata in the morning to pull in carbon dioxide for photosynthesis from the more humid air and closes them as the day’s temperature increases. It also has a root system that consists of both an exceptionally long tap root and a vast network of shallow feeder roots. Creosote bushes exhibit two different shapes to fit different microclimates. In drier areas, the plant has a cone shape in which stems funnel rainwater into the taproot. In wetter areas, the bush has a more rounded shape that provides shade to its shallow feeder roots. PREDICT How do species change over time to adjust to varying conditions? DRIVING QUESTIONS As you move through the unit, gather evidence to help you answer the following questions. -

Megaloceros Giganteus) from the Pleistocene in Poland
Palaeontologia Electronica palaeo-electronica.org Healed antler fracture from a giant deer (Megaloceros giganteus) from the Pleistocene in Poland Kamilla Pawłowska, Krzysztof Stefaniak, and Dariusz Nowakowski ABSTRACT We evaluated the skull of an ancient giant deer with a deformity of one antler. The skull was found in the 1930s in the San River near Barycz, in southeastern Poland. Its dating (39,800±1000 yr BP) corresponds to MIS-3, when the giant deer was wide- spread in Europe. Our diagnostics for the antler included gross morphology, radiogra- phy, computed tomography, and histopathology. We noted signs of fracture healing of the affected antler, including disordered arrangement of lamellae, absence of osteons, and numerous Volkmann’s canals remaining after blood vessel loss. The antler defor- mity appears to be of traumatic origin, with a healing component. No similar evaluation process has been described previously for this species.
