“…Fetal pronghorn tooth eruption patterns are thus not sufficiently correlated with mortality date to provide a useful seasonality indicator. This is consistent with earlier work (Lubinski & O'Brien, 2001;Lubinski, 2001) showing that tooth eruption patterns in post-natal pronghorn are insufficiently precise to provide more than a rough season-of-death estimate.…”

“…Some or all of the post-fetal pronghorn at Trappers Point may have been killed at other seasons. Miller (1999) analysed Trappers Point adult pronghorn dentition and considered it compatible with a spring mortality event, but pronghorn dentition is quite variable and cannot be relied on for secure seasonality indications (Lubinski, 2001;Lubinski & O'Brien, 2001). The site could therefore represent one or more large fall or winter kills mixed with relatively small spring kills.…”

“…Deciduous teeth begin to form and emerge before birth, so deciduous eruption patterns may correlate with gestation age, and therefore with mortality date. To investigate this, eruption levels of the three deciduous premolars present in the fetal pronghorn mandible were recorded for the modern fetal pronghorn sample, using a slightly modified version of Lubinski's (2001: 221) eruption scoring system. 1 Missing or broken teeth were excluded.…”

Pronghorn (Antilocapra americana) fetal remains are sometimes recovered from archaeological contexts. Pronghorn have consistent reproductive schedules so their remains may provide information on seasonality of site occupation and number of mortality events. To investigate the reliability of fetal remains for seasonality and mortality event assessment, bone size and tooth eruption were measured in a sample of modern fetal pronghorn remains with known mortality dates. Results indicate a strong correlation between bone size and mortality date, but no significant correlation between tooth eruption level and mortality date. Fetal bone size was used to estimate a late April or early May mortality date at both the Oyster Ridge (48UT35) and Trappers Point (48SU1006) archaeological sites. The number of mortality events at Trappers Point was also investigated.

“…This accounts for the species' unique traits, especially their top running speed of 60 miles per hour and an endurance speed of 30 miles per hour (Byers 2003). Speed, in combination with their exceptional eyesight, is their primary defense mechanism against predators (Lubinski 2001).…”

The American West’s longest large mammal migration: clarifying and securing the common interest

Over the last 10 years, conflict has grown over a 170-mile pronghorn antelope (Antilocapra americana) migration between Grand Teton National Park and the Upper Green River Basin in western Wyoming. Resolving conflict in the common interest is proving difficult. This movement is the longest mammal migration in the lower 48 states, spanning the jurisdiction of three federal agencies, three Wyoming counties, and over 40 private landowners. In addition, there are over ten non-governmental conservation organizations, two major state agencies, Wyoming's executive office, and many citizens involved in the issue. There are three major problem definitions serving the beliefs of participants: the ecological-scientific (conservation biologists, environmentalists), local rights (local control, property rights), and cultural value (historic, western heritage) definitions. These definitions challenge the social and decision making processes of regional communities and government agencies. Underlying the problem of securing the common interest is the highly fragmented patterns of authority and control, misorganized arena(s), and parochial perspectives of many participants. Options promoted by participants can be loosely classified as top-down (government, expert driven) versus bottom-up (local, practice-based) approaches and reflect preferences for the distribution and uses of power and other values. Given the social and decision making context of this case, the bottom-up, practiced-based approach would likely best secure a common interest outcome.

Cranial bony projections (“headgear”) have diverse forms and functions, such as defense, species recognition, mate selection, and thermoregulation. Most commonly, they are associated with the artiodactyl infraorder, Pecora. All pecoran headgear—antlers, horns, ossicones, and pronghorns—are osseous protrusions of the frontal or parietal bone with an integumentary covering, although there is taxonomic, developmental, and compositional variation. However, compared with other pecorans, there is a dearth of literature addressing extant antilocaprids—Antilocapra americana. This study provides a foundational osteohistological description of A. americana pronghorn cores in order to start building a framework to better understand the complex interplay among microanatomy, development, behavior, environment, and phylogenetic history of pronghorn headgear. Osteohistological analysis of adult A. americana pronghorn cores reveal the inner medullary region is composed of trabecular bone. Based on similar studies in bovids, we propose that these trabeculae may function to reduce the effects of repeated loading incurred by intraspecific combat. The deep aspect of the outer region was found to be composed of compacted coarse cancellous bone and primary bone remodeled to dense Haversian bone, in both male and female specimens, respectively, and superficially composed of highly vascularized fibrolamellar bone. The presence of fibrolamellar bone may indicate that the bone is fast‐growing, and its presence at the periosteal surface suggests protracted growth of the pronghorn core beyond sexual maturity.
