Hunter A.W., Rees J. (2010) A new echinoderm faunule from the Lower Jurassic (Pliensbachian) of southern Sweden // Bulletin of the Geological Society of Denmark, Vol. 58, pp. 66–73.
In Sweden, Jurassic echinoderms are extremely rare. This present study documents an Early Jurassic echinoderm assemblage collected from a temporary exposure near Helsingborg in Skåne, southern Sweden, which includes a previously undescribed species of isocrinid crinoid, Isocrinus ranae sp. nov., and an acrosaleniid echinoid. The Swedish specimens demonstrate that even limited echinoderm material from small exposures can be assigned to a high systematic level and provide data of
considerable significance to the evolution of the group as a whole.
