La presencia de dos poblaciones de la especie Condylopyge cruzensis Liñán y Gozalo, 1986 ha posibilitado realizar un estudio morfomé- trico y poblacional de la misma. Por otro lado, se ha identificado por primera vez el taxón Peronopsis aff. longinqua Öpik, 1979, lo que puede ser considerado como una herramienta más que apoye la correlación propuesta para el piso Leoniense y el Ordian/early Templentonian de Australia.

    Enrolled agnostids from Cambrian of Spain provide new insights about the mode of life in these forms JORGE ESTEVE & SAMUEL ZAMORA Enrolled agnostids have been known since the beginning of the nineteenth century but assemblages with high number of enrolled specimens are rare. There are different hypotheses about the life habits of this arthropod group and why they en- rolled. These include: a planktic or epiplanktic habit, with the rolled-up posture resulting from clapping cephalon and pygidium together, ectoparasitic habit or a sessile lifestyle, either attached to seaweeds or on the sea floor. Herein we de- scribe two new assemblages from the middle Cambrian of Purujosa (Iberian Chains, North Spain) where agnostids are minor components of the fossil assemblages but occasionally appear enrolled. The taphonomic and sedimentological data suggest that these agnostids were suddenly buried and rolled up as a response to adverse palaeoenvironmental con- ditions. Their presence with typical benthic components supports a benthic mode of life for at least some species of agnostids. • Key words: middle Cambrian, Gondwana, arthropods, behavior, Spain.

    Setting the Methodological Framework for Accessibility in Geo-Mining Heritage Settings—An Ongoing Study of Iglesiente Area (Sardinia, Italy)

    sustainability Article Setting the Methodological Framework for Accessibility in Geo-Mining Heritage Settings—An Ongoing Study of Iglesiente Area (Sardinia, Italy) Nađa Bereti´c* and Alessandro Plaisant Department of Architecture, Design and Urbanism, University of Sassari, 07041 Alghero, SS, Italy * Correspondence: [email protected]; Tel.: +39-3664571049 Received: 31 March 2019; Accepted: 25 June 2019; Published: 28 June 2019 Abstract: This paper aims to discover why and how accessibility is fundamental to sustainable local development in heritage settings. We discussed the dimensions and variables of accessibility that control the development. Correspondingly, we proposed an interpretative framework for sustainable development planning and management of low urbanized spatial settings and accessibility for the Iglesiente Geo-mining heritage in Sardinia (Italy). The Iglesiente area is affected by a deep post-mining crisis that is reflected in poor socioeconomic conditions and an evident space oriented set of problems (a disorder in landscape matrix, low readability of space, scarce infrastructure and low accessibility). To revert negative trends of space-related problems, the paper proposes a theoretical model acting as an anticipatory landscape planning tool. The model copes with the context-specific problems in combination with theoretical findings. It acts at various scales through the definition of boundaries and variables of the internal and external environment, providing the territorial matrix of equity and cohesion. Furthermore, we argued the limitation and advantages of the model to its implementation capacity for the Geo-mining heritage and low-urbanized spatial settings. The empirical findings from an ongoing project about accessibility to territorial knowledge and services in the Iglesiente area, currently in progress, allow us to test and adjust the methodological framework in the next steps.

With a few exceptions, they were previously referred only to Ptychoparia striata. Three genera are recently distinguished: Ptychoparia Hawle & Corda, 1847, Ptychoparioides Růžička, 1940, and Mikaparia gen. nov. Seven species are described: three are revised, four are new, and two is left in open nomenclature; their stratigraphical ranges and significance are discussed. A new stratigraphical subdivision of the Middle Cambrian of the Skryje-Týřovice area is suggested, including three assemblage zones and three barren zones. Four substrate and bathymetrically controlled trilobite associations are recognized in the Skryje-Týřovice area. • Key words: Bohemia, Middle Cambrian, trilobites, new taxa, biostratigraphy.

As a part of the work carried out by the Electrical Prospecting Co. (A.-B. Elektrisk Malmletning) in order to search for gas in the Lower Cambrian of Öland, a deep boring was made in the autumn of 1933 into a little flat dome at Mossberga, about 12 km S of Borgholm. The Company had the courtesy to present the core to the Geological Survey, and thus the present writer had the opportunity of subjecting it to a doser investigation, the results of which are given below.

ICTs allow a rapid diffusion of 15 data not only through institutional channels but also through social networks where the smart 16 community share experiences and perceptions. In this sense, ICTs become strategic tools to support 17 the promotion of sustainable tourism development of territories, especially if the digital data are 18 organised within a circular smart dashboard, a decision support tool in which the information 19 output provided by the system is used in a circular way, that is putting it as a new input for the 20 system. This research focuses on the case study of the Santa Barbara Walk (SBW), an ancient mining 21 route in the Sulcis Iglesiente region (Sardinia, Italy), where the authors have recognized a state of 22 disorganization in slow tourism promotion activities.
