Article Reference Characterization of the Latest Danian Event by means of benthic foraminiferal assemblages along a depth transect at the southern Tethyan margin (Nile Basin, Egypt).
The Latest Danian Event (LDE) has been recognized on the southern Tethyan margin (Egypt; Tunisia), and in the Atlantic (Zumaia, Spain) and Pacific Oceans (ODP Site 1209). Based on a supraregional carbon isotope excursion, and a negative shift in oxygen isotopes in the Pacific it has been suggested that the LDE is an early Paleogene transient warming event. So far the environmental effects of the LDE have been observed in few sections and details on its impact and duration are scarce. We present a quantitative study of benthic foraminiferal assemblages retrieved from five sections along a depth transect on the Paleocene southern Tethyan shelf (Nile Basin, Egypt) to assess paleoenvironmental change during the LDE. The lithologic sequences and foraminiferal assemblages indicate that the onset of the LDE is related to widespread shelf dysoxia. The organic-rich laminated marls of lower LDE bed I contain levels devoid of benthic foraminifera. During the later stage of the LDE (dark-gray shales of bed II) the shelf is repopulated by a Neoeponides duwi benthic assemblage, occurring in all sections, initiating a gradual restoration of normal-marine shelf environments. Q-mode and R-mode correspondence analysis assist in the interpretation of the N. duwi assemblage, which is related to disturbed conditions at the sea floor following oxygen depletion and increased organic loading. The sharp lithologic boundary at the base of the LDE suggests that the event coincides with a rapid transgression following a sea-level fall, with an estimated amplitude of ~ 50 m or less. Comparison with the Dan-C2 and ELPE/MPBE, two proposed transient warming episodes preceding and postdating the LDE, shows that the three Paleocene events have several characteristics in common. However, the duration of the LDE (~ 200 kyr) exceeds the estimated duration of the other events, and a sea-level cycle is only reported from the LDE.

Article Reference Characterization of the placoderm (Gnathostomata) assemblage from the tetrapod-bearing locality of Strud (Belgium, Upper Famennian)
The placoderm fauna of the late Famennian tetrapod-bearing locality of Strud, Belgium, is studied on the basis of historical and newly collected material. It includes the previously described antiarch Grossilepis rikiki, the groenlandaspidid Turrisaspis strudensis sp. nov. and the actinolepidoideid Phyllolepis undulata. P. undulata is thoroughly described and joins the list of the valid Phyllolepis species confidently diagnosed. A morphometrical analysis performed on the centronuchal and anterior ventrolateral plates of the Phyllolepis material demonstrates that there is only one species of Phyllolepis in Belgium (thus, Phyllolepis konincki becomes a junior synonym of P. undulata), that P. rossimontina (Pennsylvania) is a synonym of P. undulata and that the unity of the genus Phyllolepis is strongly supported, although the characterization of several species within this genus is blurred. The strong resemblance between the faunal compositions in Strud and Red Hill (Pennsylvania, USA) suggests important faunal exchanges between these regions of the Euramerica landmass.

Article Reference Checklist of ant (Hymenoptera: Formicidae) species from Nyungwe tropical rain forest, South-Western Rwanda
Tropical rain forests are inhabited by a wide range of plant and animal diversity. However, little is known about the diversity of ant (Hymenoptera: Formicidae) species in these areas. To fill the gap, a study has been conducted in seven sites inside Nyungwe National Park, a tropical rain forest located in South-Western Rwanda. Data have been collected in October 2021 through a quick sampling using pitfall traps, arboreal traps, baiting, Winklers, and hand searching of nests in leaf litter, soil, rotten and fallen wood, and under stones. Collected ant specimens have been identified to subfamily, genus and species levels by using the identification keys. Names of species have been confirmed after comparing the findings with the specimens housed at the Royal Belgian Institute of Natural Science (Brussels, Belgium) and at Kiko Gomez’s personal collection (Barcelona, Spain). A total of 7 subfamilies, 28 genera and 74 species were sampled. The subfamily Myrmicicnae had more genera and species compared with other subfamilies. Further, 9 genera and 43 species were collected in Rwanda for the first time, while 13 species were potentially undescribed ant species. High number of species has been sampled in the sites located in secondary forest at Karamba (53 species) and Pindura (33 species). We recommend intensive sampling in other locations of Nyungwe tropical rainforest and in the rest of Rwanda mountain tropical rain forests to get a clear view on the diversity of ant species in Rwanda.

Article Reference Chronologic and geographic variability of neurovascular structures in the human mandible.
OBJECTIVES: To compare the dimensions of mandibular anatomical landmarks of human mandibles of three different chronological periods and seven different geographic regions. METHODS: Cone beam computed tomography (CBCT) images were acquired fromhuman mandibles of three different chronological periods (Neolithic, Medieval and 19-20th Century). The 19-20th Century consisted of seven human mandibular samples from different geographic locations. Image analysis consisted of comparing anatomic variability and dimensions of the mandibular, lingual and incisive canals, mental foramen and their relationship to specific reference teeth as such to determine geographic region and historic period variabilities. RESULTS: Therewere statistically significant differences between the 19-20th Century group andthe Medieval and Neolithic groups. The 19-20th Century group differed significantly in mandibular canal diameter, tooth root length, length of the lateral lingual canal. In addition, the group also differed from the Medieval sample for the lateral lingual foramen diameter and the midline lingual canal length. Furthermore, the prevalence of anatomic variations was significantly different for the geographic samples tested, with double mental foramina significantly more present in the Congolese sample, and significantly more lateral lingual canals noted in Indonesian and Greenland Eskimo samples. CONCLUSIONS: This study suggests that mandibular neurovascularisation may show some geographic as well as historic variation. Further studies on larger data samples are needed to verify this statement, as such that it can be potentially used in anthropology and forensic dentistry. More research is also needed to address whether the geographic and historic variations are linked, as well to investigate evolutionary trends in these structures.
