'Mediterranean Province' hyoliths from the middle Cambrian and Upper Ordovician of Sweden

Malinky, John M.; Eriksson, Mats LU and Ahlberg, Per LU (2009) In GFF 131(4). p.281-291
Abstract
Nine species of hyoliths are described based on material collected in Skane, southern Sweden, during the first half of the last century. The material derives from the middle Cambrian (Cambrian provisional Series 3) Exsulans Limestone Bed at Almbacken east of Lund and the Upper Ordovician (Katian-Hirnantian) Lindegard Formation at Tommarp west of Simrishamn. The Almbacken assemblage consists of three taxa; Nephrotheca ruderalis Marek, 1989?, Buchavilites sp., and Orthothecid sp. 3. The Tommarp assemblage comprises Bactrotheca deleta Novak, 1891, Circotheca sp., Sololites sp., Orthothecid sp. 1 and 2, and one species of Quadrotheca Sysoev, 1958. Albeit small, the collections, altogether comprising some twenty specimens, have important... (More)
Nine species of hyoliths are described based on material collected in Skane, southern Sweden, during the first half of the last century. The material derives from the middle Cambrian (Cambrian provisional Series 3) Exsulans Limestone Bed at Almbacken east of Lund and the Upper Ordovician (Katian-Hirnantian) Lindegard Formation at Tommarp west of Simrishamn. The Almbacken assemblage consists of three taxa; Nephrotheca ruderalis Marek, 1989?, Buchavilites sp., and Orthothecid sp. 3. The Tommarp assemblage comprises Bactrotheca deleta Novak, 1891, Circotheca sp., Sololites sp., Orthothecid sp. 1 and 2, and one species of Quadrotheca Sysoev, 1958. Albeit small, the collections, altogether comprising some twenty specimens, have important paleobiogeographic implications for these metazoans. All hyoliths documented herein were formerly regarded as occurring solely in the 'Mediterranean' paleobiogeographic province, encompassing central and southwestern Europe, and North Africa. The material at hand reveals that the distribution of Buchavilites Marek, 1975, Circotheca Sysoev, 1958, Nephrotheca Marek, 1967, Quadrotheca, and Sololites Marek, 1967 is now extended to Baltica, further eroding the assumed strongly provincial nature of these organisms.
