Gk. Khursevich et Sl. Vanlandingham, MORPHOLOGY AND STRATIGRAPHY OF SOME MESODICTYON SPECIES (BACILLARIOPHYTA) FROM UPPER MIOCENE FRESH-WATER DEPOSITS OF IDAHO AND NEVADA, USA, Nova Hedwigia, 60(3-4), 1995, pp. 467-478
Detailed studies of an upper Miocene diatomaceous interbed (circa 8 m.
y.) in the Banbury Ba salt Formation of Gooding County, Idaho, yielded
Mesodictyon sectorale n.sp. and M. undulatum. Mesodictyon sp. A from
diatomaceous beds (circa 10-11 m.y.) in the Coal Valley or = formation
in Lyon County, Nevada, compared favorably in many respects with the
morphology of M. undulatum, bur it may be a new species.
