J. Maletz et So. Egenhoff, Late Tremadoc to early Arenig graptolite faunas of southern Bolivia and their implications for a worldwide biozonation, LETHAIA, 34(1), 2001, pp. 47-62
The graptolite faunal succession of the late Tremadoc to early Arenig in so
uthern Bolivia is established from the Cieneguillas and Culpina sections an
d compared with faunas from other regions. The succession yields important
data for the discussion on the proposed GSSP at the base of the Tetragraptu
s approximatus Zone and the completeness of the successions in eastern Nort
h America and Scandinavia. The graptolite faunas of the Aorograptus victori
ae, Kiaerograptus supremus, Araneograptus murrayi, Hunnegraptus copiosus an
d Tetragraptus phyllograptoides zones are reviewed and the faunal associati
ons discussed. The Kiaerograptus supremus Zone is regarded as a local Scand
inavian biozone.
