Osteological structure of Alburnoides holciki Coad & Bogutskaya, 2012 from Hari River was described. Three specimens were cleared and stained for osteological examination and its detailed osteological characteristics and differences with available osteological data of other members of the family Cyprinidae, subfamily Leuciscinae, were provided. The genus Alburnoides had no unique osteological characteristics that can be used for genus identification. However, there are much variation in the osteological structures of the specimens, especially, the caudal skeleton.

This paper presents the results of a comparative study of five osteological complexes, the infraorbital bones, branchial arches, urohyal bone, interdigitation of the median fins, and the caudal fin skeleton, of some members of the fish family Tripterygiidae. Osteological characters that may prove valuable for taxonomic purposes are described, and on the basis of the material handled, their use to separate species within the family is discussed. Several formulae were developed for the distribution of the osteological complexes of the dorsal fin, dorsal and ventral caudal procurrent ray distribution, and caudal fin in the different tripterygiid species studied.

SUMMARY 1. Support is cited for the establishment of a separate family, Chacidae comprising the monotypic genus Chaca based on the obtained osteological data. 2. The osteological characterisation of family Chacidae as well as genus Chaca is provided: very broad and depressed skull; very wide mouth gape bounded by unequal jaws; quite broad ethmoid with long and stout cornua; strongly projecting lateral ethmoid; toothless but conspicuous vomer; forked lachrymal; suborbitals lacking; very much reduced nasals; occipital process peculiarly modified. Movable premaxillae, quite large and broad palatine; minute ectopterygoid; hyomandibula solely sustained from the sphenotic; single hypohyal; eight branchiostegal rays; no basibranchials and gill-rakers and single pharyngobranchial. 3. The relationship of the family Chacidae with the Siluridae, Plotosidae, Bagridae and Sisoridae on the evidence of osteology is discussed and osteological support is found for its close affinity with the Sisoridae. 4. A brief discussi...

The purpose of this article is threefold: (1) to provide a brief historical overview of human and nonhuman osteological studies in classical archaeology to get a sense of why and how the disciplines developed as they did; (2) to examine the current state of research in human osteology and zooarchaeology in the classical context, providing examples of case studies to help highlight the value (and limitations) of osteological analyses in reconstructing aspects of ancient Greek and Roman cultures and the environments in which they lived; and (3) to outline future directions for these disciplines, specifically in terms of connections that human osteologists and zooarchaeologists can share with one another, and how both, in turn, can cultivate ties to the wider fields of classics, archaeology, and anthropology to increase our knowledge of the natural and cultural worlds of antiquity. While some aspects of osteological work in classical archaeology remain underdeveloped, the future holds strong promise for greater use and integration of osteological data within this context.

The difficullty to distinguish between sheep and goats is a well-known problem in archaeology and osteology. Distinguishing sheep and goats in archaeological animal remains takes time and time is often limited for osteologists. Because of this difficulty osteologists and archaeozoologists often use the term sheep/goat or ”ovicaprids” in their analytical reports. But even if the term sheep/goat comprise both species, this is often not the case when archaeologists and osteologists interpret and present archaeological findings. Sheep usually dominates in the interpretations and is often seen as a more important animal than goats which ultimately lead to false representations of the species and their relation to humans in the past.Zeder and Lapham (2010) have gathered criterias for post-cranial bone elements which show a high degree of reliability in osteological species determination between sheep and goats. However, when working on archaeological remains you do not know if the evaluation is done correctly. In this thesis, the use of ocular osteological methods from by Zeder and Lapham (2010) are combined with genetical analyzis of selected sheep and goat bones from an archaeological assemblage in order to evaluate how well these osteological methods perform and assess which criterias on the bone elements can be seen as reliable when used to distinguish between the species.According to the results, only three criterias of a total of 21 criterias are seen as reliable. It is also apparent that previous osteological experience is relevant for successfully distinguish between sheep and goat with these methods. However, several criterias show tendencies towards reliability and are probably affected by the small sample set for each bone element, few osteological analysts, and the fact that all genetically analyzed bones resulted in sheep.

Knowledge of the osteology of species of the Leptodactylus melanonotus group is limited. Nevertheless, osteological characters are useful to diagnose species to, to propose phylogenetic relationships, to understand patterns of morphological evolution, and to predict biological function associated with morphology. Here, we describe the whole osteology of Leptodactylus podicipinus; we have special interest in osteological and morphometric characters whose interpopulational and intersexual differences can be related with fossorial habits. Individuals from the Pantanal, Brazil, were compared with L. podicipinus from northern Argentina and central and southern Paraguay by analyzing morphometric and osteological characters. The quantitative data revealed sexual dimorphism in tarsus length in the specimens from the Pantanal. The observed interpopulation osteological differences could not be associated with burrowing habits. Osteologically, L. podicipinus is intermediate between the members of the Leptodactylus fuscus group, which is more specialized for digging, and the generalized L. melanonotus, Leptodactylus latrans, and Leptodactylus pentadactylus groups.
