Similarities in late Middle Cambrian trilobite, inarticulate brachiopod and molluscan faunas are apparent between Bornholm (Denmark) and New Zealand. Tuarangia gravgaerdensis sp. nov. is described from the late Middle Cambrian Andrarum Limestone of Bornholm, Denmark. The Andrarum Limestone is stratigraphically correlated with the Tasman Formation, New Zealand, from where the genus Tuarangia was first described. A single specimen, referred to Tuarangia, has been found in an erratic boulder from NW Poland. The boulder is estimated to be of early Late Cambrian age. The initial taxonomic assignment of Tuarangia to the Bivalvia, Subclass Pteriomorphia, is upheld. The distance between Bornholm and New Zealand, the position at opposite hemispheres, and the palaeogeography in general clearly indicate isocommunities with restricted possibility of exchange of the gene pool at species level. 相似文献

In this paper I analyze how different aspects of identity combine to shape the experiences of seven young lesbians in public space in Manresa, a non-metropolitan city in Catalonia. I argue that their experiences need to be understood intersectionally and spatially, as complex processes that involve the mutually constituted identities that shift in space. I focus on interviews and Relief Maps to show how these dynamics work and how they are related to larger social processes such as the heteronormalization and adultification of public space. 相似文献
