Mk. Boudagher-fadel et Ar. Lord, The evolution of Lepidocyclina (L.) Isolepidinoides, L. (Nephrolepidina) Nephrolepidinoides sp nov., L. (N.) Brouweri and L. (N.) Ferreroi in the late Oligocene-Miocene of the Far East, J FORAMIN R, 30(1), 2000, pp. 71-76
Material from Borneo and Sumatra show that there is a morphological evoluti
on from Lepidocyclina (Lepidocyclina) isolepidinoides van der Vlerk, 1929,
to L. (Nephrolepidina) nephrolepidinoides sp. nov., L. (N.) brouweri Rutten
, 1924 and L. (N,) ferreroi Provale, 1909, The lineage demonstrates one of
the evolutionary progressions from Lepidocyclina (Lepidocyclina) to Lepidoc
yclina (Nephrolepidina) for the Far East region.
