Recent field surveys performed in the newly-discovered Taurida Cave (Crimea, Russia, Late Villafranchian, 1.8–1.5 Ma) enabled us to unearth dentognathic remains of the dirk-toothed cat Megantereon. Here we describe in detail the recovered remains further comparing it anatomically and biometrically with coeval Eurasian and African sites. The performed analysis suggests the inclusion of the Taurida remains in the hypodigm of the Villafranchain European species Megantereon adroveri, a medium-sized saber-toothed cat poorly known in Europe as a consequence of the scarcity and fragmentary nature of the known remains. Our results and the putative transitional characters displayed by the Taurida specimen support the idea put forward by previous authors of a continuous European lineage of dirk-toothed cats.
In the late Miocene deposits in the Taralik–Cher locality (Tuva Republic), fossil remains of a giant mustelid of the genus Eomellivora Zdansky, 1924 have been found. This finding is the first reliable evidence of the Eomellivora inhabiting the modern Russia. Teeth of the Eomelliovra from Taralik–Cher are similar in size to those of E. wimani and E. piveteaui from the late Miocene in Eurasia. The morphology of teeth of the material from Tuva is most similar to that of E. ursogulo; therefore, it is considered a small form of Eomellivora ursogulo. The described finding expands the understanding of diversity, variability, and distribution of representatives of the genus Eomellivora in Asia during the late Miocene. 相似文献

The main aim of this work was by using transcranial magnetic stimulation to investigate mechanisms of interhemispheric organization the emotion in the healthy and patients with epilepsy. The research was carried out on three groups: the first and second groups of healthy and third group of the patients with idiopatical epilepsy. The first and third groups received transcranial magnetic stimulation on right and left frontalis area. The second group was control (sham transcranial magnetic stimulation). Is shown, that transcranial magnetic stimulation of right frontalis area increases the examining time on negative photos and decreases on positive photos. Transcranial magnetic stimulation of left frontalis area in the healthy and patients with epilepsy increases the examining time on positive photos and decreases on negative photos. The right hemisphere at the healthy and patients with epilepsy in the greater degree is connected to negative marks of emotions, and left hemisphere with positive marks of emotions. 相似文献
The vertebrate fauna from the cave deposits in Imanai Cave in the Southern Urals (53°02′ N, 56°26′E) has been studied. It contains 715 bones that belonged to at least 11 individuals of fossil lion (Panthera (Leo) ex gr. fossilis-spelaea). It has been established that this is one of the largest Eurasian burial sites of fossil lions. The bones were accumulated due to the natural death of animals inside the cave. The age and sex estimations have shown that at least six adult males and five adult females died there. According to the accompanying fauna, radiocarbon, geochemical, and mineralogical analyses and archaeological finds, the interval of the lion bone accumulation is determined as the first half to middle of Late Pleistocene (OIS 5–3). 相似文献
Since 1985, transcranial magnetic stimulation (TMS) has been widely used for the investigation of different processes in the human central nervous system. We studied the thresholds of the motor-evoked responses (MER) during TMS and their hemispheric differences in healthy subjects and patients with brain tumors of different localization: in the brainstem projection, left and right motor areas, and left frontal-temporal area. The obtained results testify to a lower threshold of MER in healthy subjects during TMS of the dominant hemisphere. In patients with brainstem tumors, there was a decrease in the thresholds of MER during TMS. In patients with tumors in the motor area, the thresholds of MER were increased on the lesion side, whereas in patients with tumors in the left temporal area, the thresholds were significantly decreased during TMS of the lesioned hemisphere. 相似文献
