A review of studies of sexual dimorphism in the vertebrate fossil record revealed methods that were selected for use in ceratopsids. Mountain goats, bison, and pronghorn were selected as exemplar taxa for a proof of principle study that tested the selected methods, and informed and guided the investigation of sexual dimorphism in dinosaurs. Skulls of these exemplar taxa were measured in museum collections, and methods of analysing morphological variation were tested for their ability to demonstrate sexual dimorphism in their horns and horncores. -

PALEOBIOLOGY OF ARCHAEOHIPPUS (MAMMALIA; EQUIDAE), A THREE-TOED HORSE FROM THE OLIGOCENE-MIOCENE OF NORTH AMERICA JAY ALFRED O’SULLIVAN A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 2002 Copyright 2002 by Jay Alfred O’Sullivan This study is dedicated to my wife, Kym. She provided all of the love, strength, patience, and encouragement I needed to get this started and to see it through to completion. She also provided me with the incentive to make this investment of time and energy in the pursuit of my dream to become a scientist and teacher. That incentive comes with a variety of names - Sylvan, Joanna, Quinn. This effort is dedicated to them also. Additionally, I would like to recognize the people who planted the first seeds of a dream that has come to fruition - my parents, Joseph and Joan. Support (emotional, and financial!) came to my rescue also from my other parents—Dot O’Sullivan, Jim Jaffe and Leslie Sewell, Bill and Lois Grigsby, and Jerry Sewell. To all of these people, this work is dedicated, with love. ACKNOWLEDGMENTS I thank Dr. Bruce J. MacFadden for suggesting that I take a look at an interesting little fossil horse, for always having fresh ideas when mine were dry, and for keeping me moving ever forward. I thank also Drs. S. David Webb and Riehard C. Hulbert Jr. for completing the Triple Threat of Florida Museum vertebrate paleontology. In each his own way, these three men are an inspiration for their professionalism and their scholarly devotion to Florida paleontology. -

Brachiopods from the Mobarak Formation, North Iran
GeoArabia, 2011, v. 16, no. 3, p. 129-192 Gulf PetroLink, Bahrain Tournaisian (Mississippian) brachiopods from the Mobarak Formation, North Iran Maryamnaz Bahrammanesh, Lucia Angiolini, Anselmo Alessandro Antonelli, Babak Aghababalou and Maurizio Gaetani ABSTRACT Following detailed stratigraphic work on the Mississippian marlstone and bioclastic limestone of the Mobarak Formation of the Alborz Mountains in North Iran, forty-eight of the most important brachiopod taxa are here systematically described and illustrated. The ranges of the taxa are given along the Abrendan and Simeh Kuh stratigraphic sections, located north of Damgham. The examined brachiopod species date the base of the Mobarak Formation to the Tournaisian, in absence of age-diagnostic foraminifers. Change in brachiopod settling preferences indicates a shift from high energy, shallow-water settings with high nutrient supply in the lower part of the formation to quieter, soft, but not soppy substrates, with lower nutrient supply in the middle part of the Mobarak Formation. Brachiopod occurrence is instead scanty at its top. The palaeobiogeographic affinity of the Tournaisian brachiopods from North Iran indicates a closer relationship to North America, Western Europe and the Russian Platform than to cold-water Australian faunas, confirming the affinity of the other biota of the Alborz Mountains. This can be explained by the occurrence of warm surface-current gyres widely distributing brachiopod larvae across the Palaeotethys Ocean, where North Iran as other peri- Gondwanan blocks acted as staging-posts. INTRODUCTION The Mississippian Mobarak Formation of the Alborz Mountains (North Iran) has been recently revised by Brenckle et al. (2009) who focused mainly on its calcareous microfossil biota and refined its biostratigraphy, chronostratigraphy and paleogeography. -

Its rapid burial in a fine-grained sediment under anoxic conditions led to the formation of one of the earliest Cambrian Lagerst7tte. All the organisms of the biota were adapted to a life under dysaerobic conditions. It seems possible that the adaptations of many Cambrian organisms, which composed the trophic nucleus of the Sinsk Algal Lens palaeocommunity to low oxygen tensions allowed them to diversify in the earliest Palaeozoic, especially during the Cambrian. Nowadays these groups comprise only a negligible part of communities and usually survive in settings with low levels of competition. Nonetheless, the organization of the Algal Lens palaeocommunity was not simple, it consisted of diverse trophic guilds. The tiering among sessile filter-feeders was well developed with the upper tier at the 50 cm level. In terms of individuals, the community was dominated by sessile filter-feeders, vagrant detritophages, and diverse carnivores/scavengers. The same groups, but in slightly different order, comprised the bulk of the biovolume: vagrant epifaunal and nektobenthic carnivores/ scavengers, sessile filter-feeders, and vagrant detritophages. -

Biodiversity Patterns Across the Late Paleozoic Ice Age
Palaeontologia Electronica palaeo-electronica.org Biodiversity patterns across the Late Paleozoic Ice Age Barbara Seuss, Vanessa Julie Roden, and Ádám T. Kocsis ABSTRACT The Late Palaeozoic Ice Age (LPIA, Famennian to Wuchiapingian) witnessed two transitions between ice- and greenhouse conditions. These alternations led to drastic alterations in the marine system (e.g., sea-level, habitat size, sea-surface temperature) forcing faunal changes. To reassess the response of the global marine fauna, we ana- lyze diversity dynamics of brachiopod, bivalve, and gastropod taxa throughout the LPIA using data from the Paleobiology Database. Diversity dynamics were assessed regarding environmental affinities of these clades. Our analyses indicate that during the LPIA more taxa had an affinity towards siliciclastic than towards carbonate environ- ments. Deep-water and reefal habitats were more favored while grain size was less determining. In individual stages of the LPIA, the clades show rather constant affinities towards an environment. Those bivalves and brachiopods with an affinity differ in their habitat preferences, indicating that there might have been little competition among these two clades. Origination and extinction rates are similar during the main phase of the LPIA, whether environmental affinities are considered or not. This underlines that the LPIA marine fauna was well adapted and capable of reacting to changing environ- mental and climatic conditions. Since patterns of faunal change are similar in different environments, our study implies that the changes in faunal composition (e.g., diversity loss during the LPIA; strong increase of brachiopod diversity during the Permian) were influenced by the habitat to only a minor degree but most likely by yet unknown abiotic factors.
