Note on Anthraconauta calcifera in the Upper Coal Measures of Denbighshire
Published online by Cambridge University Press: 01 May 2009
Extract
The diminutive lamellibranch Anthraconaitta calcifera (Hind) was described by Hind in 1899, and the specimens were from a limestone at the bottom of the Newcastle-under-Lyme Beds, the middle division of the Upper Coal Measures of North Staffordshire. Similar shells occur at the base of the Coed-yr-allt Beds, the middle division of the Upper Coal Measures of Denbighshire (Gibson, 1901)and further specimens have since been noted (Wedd, 1928). A critical study has recently been made of specimens of A. calcifera from the type locality in North Staffordshire (Dix and Trueman 1931).
