Sexual Dimorphism in Perissodactyl Rhinocerotid Chilotherium Wimani from the Late Miocene of the Linxia Basin (Gansu, China)
Sexual dimorphism in perissodactyl rhinocerotid Chilotherium wimani from the late Miocene of the Linxia Basin (Gansu, China) SHAOKUN CHEN, TAO DENG, SUKUAN HOU, QINQIN SHI, and LIBO PANG Chen, S., Deng, T., Hou, S., Shi, Q., and Pang, L. 2010. Sexual dimorphism in perissodactyl rhinocerotid Chilotherium wimani from the late Miocene of the Linxia Basin (Gansu, China). Acta Palaeontologica Polonica 55 (4): 587–597. Sexual dimorphism is reviewed and described in adult skulls of Chilotherium wimani from the Linxia Basin. Via the anal− ysis and comparison, several very significant sexually dimorphic features are recognized. Tusks (i2), symphysis and oc− cipital surface are larger in males. Sexual dimorphism in the mandible is significant. The anterior mandibular morphology is more sexually dimorphic than the posterior part. The most clearly dimorphic character is i2 length, and this is consistent with intrasexual competition where males invest large amounts of energy jousting with each other. The molar length, the height and the area of the occipital surface are correlated with body mass, and body mass sexual dimorphism is compared. Society behavior and paleoecology of C. wimani are different from most extinct or extant rhinos. M/F ratio indicates that the mortality of young males is higher than females. According to the suite of dimorphic features of the skull of C. wimani, the tentative sex discriminant functions are set up in order to identify the gender of the skulls. Key words: Mammalia, Perissodactyla, Chilotherium wimani, sexual dimorphism, statistics, late Miocene, China.

Competition Structured a Late Cretaceous Megaherbivorous Dinosaur Assemblage Jordan C
www.nature.com/scientificreports OPEN Competition structured a Late Cretaceous megaherbivorous dinosaur assemblage Jordan C. Mallon 1,2 Modern megaherbivore community richness is limited by bottom-up controls, such as resource limitation and resultant dietary competition. However, the extent to which these same controls impacted the richness of fossil megaherbivore communities is poorly understood. The present study investigates the matter with reference to the megaherbivorous dinosaur assemblage from the middle to upper Campanian Dinosaur Park Formation of Alberta, Canada. Using a meta-analysis of 21 ecomorphological variables measured across 14 genera, contemporaneous taxa are demonstrably well-separated in ecomorphospace at the family/subfamily level. Moreover, this pattern is persistent through the approximately 1.5 Myr timespan of the formation, despite continual species turnover, indicative of underlying structural principles imposed by long-term ecological competition. After considering the implications of ecomorphology for megaherbivorous dinosaur diet, it is concluded that competition structured comparable megaherbivorous dinosaur communities throughout the Late Cretaceous of western North America. Te question of which mechanisms regulate species coexistence is fundamental to understanding the evolution of biodiversity1. Te standing diversity (richness) of extant megaherbivore (herbivores weighing ≥1,000 kg) com- munities appears to be mainly regulated by bottom-up controls2–4 as these animals are virtually invulnerable to top-down down processes (e.g., predation) when fully grown. Tus, while the young may occasionally succumb to predation, fully-grown African elephants (Loxodonta africana), rhinoceroses (Ceratotherium simum and Diceros bicornis), hippopotamuses (Hippopotamus amphibius), and girafes (Girafa camelopardalis) are rarely targeted by predators, and ofen show indiference to their presence in the wild5. -

Signature: Date: 27/ 04/ 2019 I ABSTRACT The Dorcas gazelle (Gazella dorcas) is an endangered antelope in North Africa whose range is now restricted to a few small populations in arid, semi-desert conditions. To be effective, conservation efforts require fundamental information about the species, especially its abundance, distribution and genetic factors. Prior to this study, there was a paucity of such data relating to the Dorcas gazelle in Libya and the original contribution of this study is to begin to fill this gap. The aim of this study is to develop strategies for the conservation management of Dorcas gazelle in post-conflict North East Libya. In order to achieve this aim, five objectives relating to current population status, threats to the species, population genetics, conservation and strategic population management were identified. -

(eds.) - DISTRIBUTION AND MIGRATION OF TERTIARY MAMMALS IN EURASIA. A VOLUME IN HONOUR OF HANS DE BRUIJN - DEINSEA 10: 235- 253 [ISSN 0923-9308] Published 1 December 2003 The present contribution provides a comprehensive overview of the Neogene rhinoceroses of Greece and evaluates their affinities with the European and Asian species. The distribution, diver- sity and dispersal of the family in the Eastern Mediterranean are discussed in detail. Knowledge of rhinos during the Middle Miocene in Greece is still very limited, because of the scarce mate- rial. During the Late Miocene the family was diverse and abundant in Greece. The dominant form, Ceratotherium neumayri, was probably an African immigrant that invaded Southeastern Europe, Anatolia and the Middle East during the Late Miocene. This rather subhypsodont tandem-horned rhino has already achieved most of the apomorphic characters of the living Dicerotina. The con- temporary species Dihoplus pikermiensis is also common, but the origin and evolutionary rela- tionships among its Miocene and Plio-Pleistocene relatives are still controversial. The Greek Late Miocene representatives of the subfamily Aceratheriinae are obviously closer related to the Asian genera Chilotherium and Acerorhinus, than to the typical aceratheres Aceratherium, Alicornops and Hoploaceratherium found in Central and Western Europe at the same time. Chilotherium and Acerorhinus migrated into Greece from Central Asia trough Anatolia at the beginning of the Vallesian. -
