An articulated skeleton of Thalassocnus natans (Xenarthra : Nothrotheriidae) and a review of some other fossil sloths provide new information on sesamoid bones located at the knee joint. A sesamoid bone and an ossified meniscus have been identified at this joint. The cyamo-fabella (posterior sesamoid of the tibio-femoral articulation) of T. natans may act like a pulley through which the tendon of...
Changes in benthic foraminiferal and mollusk assemblages from the lower part of the Upper Pliocene of the Atsipades Section (Iraklion Basin, central Crete) were studied. The Atsipades Section represents a shallowing-upward sequence from outer shelf blue–gray clays at the bottom of the sequence, deposited below the storm wave base, to shallow inner shelf deposits affected by storm waves at the top...
In this study, the lignite bearing sediments of Çardak–Tokça basin exposed in southwest Anatolia, were palynologically examined. A well preserved and diverse palynomorph assemblage indicating an Early Oligocene age was recovered from the Hayrettin and Tokça formations. The palynomorph assemblage is dominated by Pinus, Sparganiaceae, Juglandaceae and diverse tricolpate and tricolporate pollen. In addition...
The upper dentition of two Australian early Miocene mystacinids, Icarops paradox and I. aenae, from Riversleigh, Queensland, are described for the first time. Also recognised is a late Oligocene mystacinid from Lake Palankarinna, South Australia. The new fossils help refine understanding about the evolutionary history of mystacinids in Australia, including their temporal and geographical range, possible...
The low Lower Cambrian rocks from the Sierra de Córdoba, which consist of well exposed mixed facies and abundant fossil assemblages showing long stratigraphic ranges throughout the Pedroche Formation, represent one of the best successions of this age in Europe. The fossil assemblages include diverse Ovetian archaeocyaths, trilobites, small shelly fossils, calcimicrobia, trace fossils and stromatolites...
The Cave Bear skull is characterized in classic descriptions by a strong development in the frontal area. This feature gives it a characteristic step profile in lateral view. Such morphology is usually present in some adult males (brachycraneous), but it has not been described for females or young individuals. In this work, we present a study on variation in the size and shape in Cave Bear skulls...
L'analyse pollinique de la grotte de Santa Lucia superiore (Italie) a permis de reconstituer, à l'échelle locale, la végétation de l'arrière-pays ligure durant le Pléniglaciaire ancien (75 à 57 Kyr BP). La séquence pollinique montre, dans un contexte global steppique, deux phases d'expansion du couvert arboré en Ligurie. Les phases froides et arides génèrent le développement d'une steppe (NAP 92 %)...
The earliest pterygote (winged insect), dated from the Lower Carboniferous (Namurian A/E1, circa 324 millions years ago) is described from the Upper Silesian Basin in the Czech Republic. On the basis of its wing venation, it is attributed to the Archaeorthoptera Béthoux and Nel, 2002, crown group of the “Orthoptera”. Besides Apterygota (Collembola and Archaeognatha) known from the Lower Devonian,...
A well-preserved skull and articulated mandible of Shansirhinus, a horned aceratherine rhinocerotid, is described from an Early Pliocene (Gaozhuangian; approximately 5.3–4.34 Ma) locality of the Linxia Basin in Gansu, China. Comparing the new material of Shansirhinus ringstromi Kretzoi, 1942, we confirm the synonymy proposed previously for the species Chilotherium yunnanensis Tang et al., 1974, Chilotherium...
