Article Reference New hyaenodonta (Mammalia) from the middle Eocene of Myanmar
The middle Eocene Pondaung Formation in Myanmar has yielded a rich mammalian faunaincluding several Primate taxa. Hyaenodonta are known by the genera Kyawdawia, Yarshea,Orienspterodon, and two other indeterminate taxa. We describe here new material of Kyaw-dawia, including some morphological details, a new species of the hypercarnivorous genusPropterodon and an indeterminate species, different from those described earlier in Myan-mar, and characterized by a reduction of m3 and would belong to a third lineage with thesame evolutionary trend as Galecyon and the Limnocyoninae. The hyainailourines (Orien-spterodon) and hyaenodontines (Propterodon) are recorded for the first time in SoutheastAsia and these subfamilies appeared in quasi the same time in Europe illustrating probablya profound change in the carnivorous fauna among Laurasia.

Article Reference New hypogean cyclopoid copepods (Crustacea) from the Yucatan Peninsula, Mexico
Four previously unknown hypogean species of cyclopoid copepods were collected in cenotes and wells of the Yucatan Peninsula, Mexico. Diacyclops chakan sp. n. and D. puuc sp. n. differ from their congeners in combining 3-segmented swimming legs, 11-segmented antennules, and legs 1-4 endopodite segment 2 all with 2 setae. Species of Diacyclops rarely occur in tropical regions, and the Diacyclops described here are only the second and third species recorded from Mexico. The benthic D. puuc was found in the large underground reservoir of a cenote. Diacyclops chakan was encountered in such large open subterranean water basins, but more frequently and abundantly in wells. The two Mesocyclops species, M. chaci sp. n. and M. yutsil sp. n., most closely resemble their epigean benthic congener M. reidae Petkovski, but are modified by loss of some body ornament and attenuation of swimming legs and mouthparts. Mesocyclops chaci sp. n. occupies crevicular spaces (wells and small caverns). The second species, M. yutsil sp. n., with more pronounced attenuation of legs, has a planktonic life in large subterranean water volumes. The extremely attenuated appendages of both species distinguish them from all other Mesocyclops, and resemble those of the hypogean Kieferiella delamarei Lescher-Moutoué. These three species are considered as a species-flock which have radiated as specialists within a highly dynamic geomorphological environment.

Article Reference New Hypsodont Tillodont (Mammalia, Tillodontia) from the Early Eocene of India
A new tillodont, Anthraconyx hypsomylus, n. gen. n. sp., is described from the early Eocene Cambay Shale Formation at Vastan Lignite Mine, Gujarat, India. Anthraconyx hypsomylus is the smallest Eocene tillodont and is distinguished by having the most buccally hypsodont cheek teeth of any known esthonychine. The closest dental resemblances are to North American Esthonyx and Azygonyx and European Plesiesthonyx, providing further evidence of affinities between the Vastan local fauna and Euroamerican vertebrate faunas.

Article Reference New information, including anatomy of the secondary xylem, on the genus Brabantophyton (Stenokoleales) from Ronquières (Middle Devonian, Belgium)
Two pyrite permineralized stems and one root are reported from the upper Middle to lowermost Late Devonian (middle Givetian to lowermost Frasnian) locality of Ronquières (Belgium) and identified as Brabantophyton runcariense Momont et al. (Stenokoleales). The stems include a three-ribbed protostele with a central protoxylem strand and other strands disposed along the midplanes of the ribs; each specimen shows secondary xylem. Tracheids of both primary and secondary xylem show circular to elliptical, multiseriate bordered pits. Rays are 1–seriate to 4–seriate; their height is highly variable, ranging from 3 to more than 100 cells. The root includes a four-ribbed protostele. Each rib shows two exarch protoxylem strands. The root also comprises a ring of secondary xylem identical to that of the stems. The characteristics of the secondary vascular anatomy of Brabantophyton appear closer to the seed plants than to any other Devonian plant lineage. However, the presence of a bifacial vascular cambium is not demonstrated, which precludes a definitive assignment of the genus to the lignophytes. A hypothesis about the ontogenetic development of Brabantophyton is proposed on the basis of the different characteristics observed in the different stem specimens of the plant.

Article Reference New insights into Mediterranean Gallo-Roman farming: a closer look at archaeological wells in Southern France
Archaeological wells have recently become a major source of palaeoenvironmental and palaeoeconomic information, thus, providing the background for past day-to-day material life. At the site of La Lesse–Espagnac (Hérault), combined evidence from archaeobotany, morphometry and palynology, from two wells, offers a coherent picture of the diversity of the local Gallo-Roman farming economy, whose development was fuelled by the proximity of a major urban centre (Colonia Urbs Julia Septimanorum Baeterra—present day Béziers). The ever present vine growing and wine making were complemented by other food crops such as fruit trees, vegetables, condiments and cereals. The dense network of farming establishments and the scale of their production could only aggravate the extent of anthropogenic impact on the local natural woodlands and would explain the very minor role of typical thermophilous trees in the pollen diagram. The overmultiplication of these farming establishments may explain why some of them apparently ran out of momentum and eventually failed.
