The lower jaw and dentition of the traversodontid Exaeretodon riograndensis Abdala,Barberena & Dornelles,from the Brazilian Triassic (Santa Maria 2 Sequence,Hyperodapedon Assemblage Zone)

Exaeretodon riograndensis Abdala, Barberena, & Dornelles, 2002 Abdala, F., Barberena, M.C. and Dornelles, J.E.F. 2002. A new species of the traversodontid cynodont Exaeretodon from the Santa Maria Formation (Middle/Late Triassic) of Southern Brazil. Journal of Vertebrate Paleontology, 22: 313–325. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] is the most abundant traversodontid preserved in the basal Santa Maria 2 Sequence (Hyperodapedon Assemblage Zone), southern Brazil and is closely related to Exaeretodon argentinus Cabrera, 1943 Cabrera, A. 1943. El primer hallazgo de terápsidos en la Argentina. Notas del Museo de La Plata, Paleontología, 8: 317–331.  [Google Scholar] from the Ischigualasto Formation, Argentina. Previous anatomical studies of E. riograndensis have focused mainly on cranial material and little is known about the morphology of its lower dentition or postdentary bones. We describe the first fairly complete postdentary series of the mandible of E. riograndensis and provide additional information on its lower dentition. The postdentary bones of E. riograndensis include a complex coronoid, an angular with a delicate reflected lamina and a stout retroarticular process of the articular, contrasting with the morphology reconstructed for Argentinean specimens, which possess a small retroarticular process. Apart from that, the postdentary bones do not differ significantly from those known for E. argentinus, a fact expected due to the great similarity between other skeletal features of these species. Furthermore, the lower postcanines of E. riograndensis have virtually the same structure as those of E. argentinus, with an approximate quadrangular shape in occlusal view. Moreover, the transverse cusp row is placed anteriorly and comprises a lingual and a buccal cusp, and the occlusal basin delimited by the four main cusps is relatively deep. The new material does not add any taxonomically diagnostic features to E. riograndensis. However, the fossils greatly improve our understanding of the anatomy of the Brazilian species.     

A new record of an aristonectine elasmosaurid (Sauropterygia,Plesiosauria) from the Upper Cretaceous of New Zealand: implications for the Mauisaurus haasti Hector, 1874 hypodigm

O’Gorman, J.P., Otero, R.A. & Hiller, N., 2014. A new record of an aristonectine elasmosaurid (Sauropterygia, Plesiosauria) from the Upper Cretaceous of New Zealand: implications for the Mauisaurus haasti Hector, 1874 Hector, J., 1874. On the fossil Reptilia of New Zealand. Transactions and Proceedings of the New Zealand Institute 6, 333–358. [Google Scholar] hypodigm. Alcheringa 38, 504–512. ISSN 0311-5518

An indeterminate aristonectine elasmosaurid is recorded from a lower Maastrichtian bed of the Conway Formation, Waipara River, South Island, New Zealand. The described specimen (CM Zfr 104), previously considered part of the hypodigm of Mauisaurus haasti, came from the upper part of the Alterbidinium acutulum biozone, the same zone from which the only well-known aristonectine from New Zealand, Kaiwhekea katiki, is recorded. The cervical vertebrae of CM Zfr 104 have the same distinctive features (i.e., with extremely broad rather than long centra) as those from previously recorded juvenile aristonectines from Argentina, Chile and Antarctica. This new record is congruent with the biogeographic relationships of Cretaceous marine amniotes from the Weddellian Palaeobiogeographic Province (i.e., Patagonia, western Antarctica, New Zealand and southeastern Australia). Therefore, this type of vertebra is regarded as a distinctive feature of the Weddellian aristonectine elasmosaurids.

Evaluating morphological variability in lithic assemblages using 3D models of stone artifacts

Technological and morphological variability in lithic artifacts is commonly used to identify taxonomic entities in Paleolithic research contexts. Assemblages are mainly studied using either linear distance measurements or qualitative assessments of morphologies. Here, we present a method to quantify morphological variability in lithic artifacts using 3D models of stone artifacts. Our study on the sequence of the Upper Paleolithic layers V–I from the site Yabroud II in western Syria, demonstrates that utilizing 3D models provides a new insight into the variability of lithic technologies. We use quantitative data on convexities, twist and scar patterns on cores and blades, attributes previously not readily quantifiable, to trace technological change through the archaeological sequence. We are able to identify differences and translate these findings into a grouping of the layers. While layers VI–II are characterized by technological continuity and were grouped together, layers V and I can be separated from this group and represent technologically different groups chronologically before and after. Our results demonstrate the potential of 3D models for studying morphological variability in lithic assemblages.     

Using 3D scanning in the investigation of Upper Palaeolithic engravings: first results of a pilot study

This paper deals with the reinvestigation of selected engravings on slate plaquettes from the Late Upper Palaeolithic site of Gönnersdorf, Germany, by applying new 3D scanning methods for the first time. The aim of this method is to obtain further information about stylistic aspects of the depictions as well as to identify an inner chronology and interrelationship of the lines. In addition new options of 3D photography are tested as a further visual support of investigation and documentation. Previously analyses were subjective whereas the new interpretation uses impartial metric methods. In the future the more objective results will allow the comparison of engravings and their details, with the aim of discerning different artists as well as obtaining a better understanding of the art of former hunter- gatherer societies.     

The Paleolithic of Dzungaria (Xinjiang,Northwest China) Based on Materials from the Luotuoshi Site

The paper reports the results of an analysis of surface collections of artifacts made at the Luotuoshi site in Dzungaria, Xinjiang, northwest China. The site was discovered in 2004 by a joint Chinese-Russian-American archaeological expedition. A techno-typological analysis of the artifacts was carried out noting aeolian abrasion of the artifacts’ surfaces. This technocomplex is quite homogenous and is characterized by a combination of Levallois-like and subprismatic blade-based reduction techniques. Analogs of the Luotuoshi assemblage have been identified within the lithic industries of the Altai, the Orkhon-1 and Tolbor-4 sites in Mongolia, and at Shuidonggou in the Ningxia Hui Autonomous Region in China, all of which have been attributed to the Early Upper Paleolithic. Luotuoshi is the first site associated with the blade-based Early Upper Paleolithic discovered in northwest China and its particular features make it possible to correlate this technocomplex with those from southern Siberia and northern Central Asia.     

Burning wood or burning bone? A reconsideration of flotation evidence from Upper Palaeolithic (Gravettian) sites in the Moravian Corridor

This paper compares archaeobotanical and other data from new excavations at two Upper Palaeolithic sites — Dolní V?stonice II and P?edmostí I — in the Moravian Corridor, Czech Republic. Both contain the traces of broadly contemporary ‘Gravettian’ occupations during the warmer episodes of the Pleistocene which preceded the last glacial maximum. Yet their archaeobotanical remains show striking differences — those from Dolní V?stonice II being dominated by large quantities of conifer wood charcoal, while those from P?edmostí I are much more scanty and dominated by vitrified plant remains, in association with large quantities of burnt bone. We argue that these differences between these two datasets arise from different uses of fuel at either site: bone at P?edmostí I and wood at Dolní V?stonice II. Subsequently, we explore the possible reasons for this difference and argue that once likely taphonomic distinctions are accounted for, these data on fuel use offer fresh insights into the functions and durations of these Upper Palaeolithic occupations of the Moravian corridor and some possible implications for how archaeobotanical data from such sites should be interpreted.     

Mammalian fauna from Palaeolithic sites in the Upper Yenisei River basin (southern Siberia): Review of the current zooarchaeological evidence

The palaeontological data on mammal remains from two Middle Palaeolithic (ca. 125 000 years ago – 27 200 BP) and 34 (ca. 34 000–12 000 BP) Upper Palaeolithic cultural complexes in the upper part of the Yenisei River basin (southern Siberia) are considered. General features of the faunal assemblages are established. Several issues are discussed, including (a) changes in species composition through time and palaeoenvironmental implications of the zooarchaeological records; (b) patterns of human exploitation (hunting) of mammals; (c) issue of mammoth hunting and (d) possibility of domestication of dog in the late Upper Palaeolithic in the Yenisei River basin.

Monongahela subsistence-settlement change: The late prehistoric period in the lower Upper Ohio River valley

The Late Prehistoric period in the lower Upper Ohio River basin of southwestern Pennsylvania and adjacent portions of Maryland, Ohio, and West Virginia is dominated by a material-culture assemblage named Monongahela. Monongahela has been associated with subsistence-settlement systems that included a large number of upland villages that were often far removed from large river valleys. The existence of these villages has been explained as resulting from intra- and interregional warfare. While these upland villages may have obtained as a result of warfare, it is argued that they served as important links in regional divided risk strategies in response to local environmental and social risks.     

The Upper Paleolithic of Northern Asia: Achievements,problems, and perspectives. II. Central and Eastern Siberia

Earlier scholars believed that the Upper Paleolithic of Central and Eastern Siberia appeared very late. However, modern research has shown that not only was there a local Middle Paleolithic, but also there was a very early series of sites in Central Siberia which show both Middle and early Upper Paleolithic traits. These are called the Makarovo horizon and may be 70,000–50,000 years old; features derived from this horizon can be dated to about 30,000 B.P. and can be seen in the early D'uktai culture. The true early Upper Paleolithic is relatively homogeneous in Central and Eastern Siberia and includes artwork. The local Upper Paleolithic reached its florescence in the culture of Mal'ta and Bur'et', which developed out of local antecedents and which is here reinterpreted in light of recent research (including the artwork, structures, and burials). The final stages of the Upper Paleolithic show considerable variability, perhaps including some exotic traits.
