The Cambrian edrioasteroid Stromatocystites is reported and described from Spain, Sweden and Turkey. All previously known occurrences of the genus are critically reviewed, and S. flexibilis is reinterpreted as a junior synonym of S. pentangularis. Stromatocystites was biogeographically widespread and colonized different areas of Baltica, Gondwana (Arabian, eastern and western margins) and Laurentia (western Newfoundland). Stratigraphically, it ranges from Cambrian Series 2, Stage 4 to Cambrian Series 3, Drumian. Stromatocystites lived in quiet water environments with stabilized substrates. It was attached directly to the substrate by its aboral surface. As these environments were widespread throughout Baltica, Gondwana and Laurentia, availability of suitable substrates for larval settlement and oceanic palaeocurrents led to the successful development of Stromatocystites colonies. © 2015 Elsevier Masson SAS.

ERP implementations within large scale construction organizations have yielded more failures than successes. As a result of this high failure rate, the integration capability of ERP systems could not be fully understood and recognized by the construction (AEC) industry. The aim of the research presented in this paper was to investigate the role of ERP systems in enabling and facilitating Data Level Integration in construction industry organizations. In parallel with this aim, an ERP Data Level Integration Capability Matrix was developed as the metric for measuring the capability of ERP systems in enabling Data Level Integration. The matrix is validated with four case studies. The development of the matrix and the results of the case studies are presented in this article. Copyright © 2013, IGI Global.

Permian and Triassic tetrapods are very rare in Turkey. Yet this group bears important paleoenvironmental and paleogeographical signals to better understand Pangean models, and especially the geodynamic history of the Permian and Triassic in Turkey, which remains highly debated. Here we present and describe the first temnospondyls from Turkey (SE Anatolia) which consist of a Middle Permian branchiosaurid and an Early Triassic stereospondyl. The branchiosaurid is the first representative of its group in Gondwana and the first from the Middle Permian: it therefore brings important paleogeographic implications and supports the hypothesis that anamniotic tetrapods may have used trans-Pangean migration routes between Europe and Gondwana. It also brings new data to the debated depositional environment of the Permian of SE Anatolia. The Triassic stereospondyl represents one of the few tetrapods known from paleoequatorial areas and confirms a relatively rapid faunal turnover of the anamniotic fauna after the Permian-Triassic mass extinction. © 2015 Académie des sciences.
