Kurzfassung

Zwei neue mikromorphe Muschelarten aus dem Silur von Gotland werden beschrieben und zur neuen GattungKenzieana gestellt. Es handelt sich umKenzieana lata undKenzieana angusta. Manche morphologischen Merkmale vonKenzieana, vor allem die deutliche Stauchung der Schale in der Längsachse, sind für einige nicht verwandte heutige Arten charakteristisch. Wahrscheinlich handelt es sich beiKenzieana um einen siphonaten Filtrierer, der frei auf dem Sediment lag.

Abstract

Two new micromorphic bivalve species from the Silurian of Gotland are described and assigned to the new genusKenzieana, viz.Kenzieana lata andKenzieana angusta. Kenzieana exhibits morphological features characteristic of some unrelated extant species; above all a conspicuous antero-posterior flattening of the shell. Probably it was a siphonate suspension feeder with a reclining mode of life.
