Das Karbonische alter der Tiefbohrung Wanneperveen I, eine revision
Abstract
A revision of the samples from the borehole Wanneperveen I, The Netherlands, leads to the following conclusions: a) Taeniopteris parva Jongmans nov. sp., published and figured in Jongmans&VanderHeide (1953) can be identified as single pinnules of Neuralethopteris schlehani forma rectinervis (Kidston). b) The non-marine shell described as "Carbonicola" carbonaria in the same above mentioned publication, is now determined as Carbonicola cf. circinata Pastiels 1960. Consequently the age of the fossil baring sediments in the borehole Wanneperveen I must be lowered from the Autunian to the Westfalian A.
