Victoria is emerging as the region where members of the Ordovician graptolite subfamily Kinnegraptinae, revised herein, reached its highest diversity, with 16 or 17 species present, grouped in the four genera Paradelograptus Erdtmann et al. (1987), L

Two graptolites from the early Bendigonian (Early Floian, Early Ordovician) formerly placed in Didymograptus, D. eocaduceus Harris, 1933 and D. hemicyclus Harris, 1933, are shown to be members of a single population that shows extraordinary dimorphis

The Melbourne Zone comprises Early Ordovician to Early Devonian marine turbidites, which pass conformably upward into a mid-Devonian fluviatile succession. There are four pulses of Silurian to mid-Devonian deep-marine sandstone-dominated sedimentatio

The Ordovician of the southeastern Lachlan Fold Belt (LFB) is represented by two contrasting provinces: the Molong volcanic province, with shoshonitic basalts and shallow marine sediments in the north; and a very extensive but relatively thin quartzo

Two new species of Climacograptus are described from the late Gisbornian and early Eastonian (Late Ordovician) of Victoria. It is proposed that they form a lineage which can be traced from C. bicornis tridentatus Lapworth, via C. cruciformis sp. nov.

Intraplate tectonic escape along the eastern margin of Gondwanaland in Late Silurian to Middle Devonian time was caused by the eastward movement of Antarctica along a major intraplate tear. Resulting collisions caused a crustal block from the souther

Current evidence suggests that most of Victoria is underlain by a relatively thick (20 km +) basement of sialic composition of assumed Proterozoic age. This basement is nowhere exposed and its structural relationship with exposed Palaeozoic rocks is

The middle Lancefieldian (late Tremadocian) dissepimentous siculate graptolites Dictyonema macgillivrayi T. S. Hall 1897 and D. pulchellum T. S. Hall 1899 possess a biradially symmetrical proximal end development which appears to be fully homologous

The graptolite-bearing sequence across the Ordovician-Silurian boundary at Darraweit Guim, central Victoria is subdivided into four biostratigraphic units: the Dicellograptus ornatus-Climacograptus latus Zone, Climacograptus? extraordinarius Zone, Gl
