Article Reference Rinistachya hilleri gen. et sp. nov. (Sphenophyllales), from the upper Devonian of South Africa
A rich and diverse plant assemblage has been excavated from latest Devonian (Famennian) black shales of the Witpoort Formation (Witteberg Group) at Waterloo Farm, close to the city of Grahamstown (South Africa). Several specimens of a new sphenopsid have been collected. The description of this as a new taxon, here named Rinistachya hilleri, gen. et sp. nov., provides an important addition to the scarce early record of the group. Rinistachya hilleri presents a novel architecture that include apparently plesiomorphic characters, reminiscent of the organisation of the Iridopteridales (including the production of two types of laterals at one node, the location of fertile parts in loose whorls on lateral branches and an organisation of the fertile parts in which they branch several times before bearing distally elongate sporangia). Other characters unambiguously nest Rinistachya within the Sphenopsida (including presence of planate and slightly webbed ultimate appendages and lateral strobili made of successive whorls of fertile leaves with fertile parts located at their axil). This provides strong support for a close relationship between Sphenopsida and Iridopteridales. Rinistachya furthermore represents the first record of a Devonian sphenopsid from Gondwana and extends the known distribution of the Sphenopsida from the tropics to very high palaeolatitudes. It is a new sphenopsid with a peculiar organisation. The new taxon allows better characterization of the initial evolutionary radiation at the base of the group.

Article Reference Roman pottery production in Civitas Tungrorum, Central Belgium, during the first-third centuries CE.
Aspects of Roman pottery production at the workshops of Kontich, Tienen, Rumst, Grobbendonk and Clavier-Vervoz in the Civitas Tungrorum of central Belgium are explored. A total of 150 wasters from five sites were studied macroscopically, as well as via a combination of thin-section petrography, geochemistry and scanning electron microscopy, in order to gain insights into ceramic technology and aspects of the organization of production. Particular emphasis was given to the individual technological sequences and shared strategies of raw material selection, paste preparation and firing employed at the five adjacent sites. The integration of petrographic and geochemical data permitted the establishment of compositional reference groups for the Roman kiln sites of Civitas Tungrorum, which can be used to track their products within the surrounding landscape.

Article Reference Roman trade relationships at Sagalassos (Turkey) elucidated by ancient DNA of fish remains
The excavations of Roman and Early Byzantine contexts at the town of Sagalassos (Turkey) yielded fish remains belonging to species that do not occur near the site. The modern geographical distribution of the identified fish indicates trade with various regions of Anatolia, the Mediterranean coast, Egypt and/or the Levant. Trade with Levant and Egypt is evident throughout the period by the presence of Clarias, a catfish living amongst others in the Nile and Levant. Mitochondrial DNA analysis was successfully carried out on modern populations of this species from Turkey, Syria, Israel and Egypt. Several variable regions were discovered on the mitochondrial control region containing polymorphisms that distinguish the haplotypes. Primer sets were designed to amplify small fragments of ancient DNA containing these informative regions. Ancient fish DNA could be successfully extracted, amplified and sequenced. The analyses indicate that the catfish bones belong to Clarias gariepinus and that they originated from the lower Nile. In addition, this study sheds light on the understanding of the modern distribution of C. gariepinus in Anatolia.
