Eastonian trilobite faunas of the Gordon Group in Tasmania include the new
species Ceraurinella oepiki, Erratencrinurus trippi, and Pliomerina trisulc
ata, as well as a reedocalymeninid probably allied to Sarrabesia Hammann &
Leone, 1997. Ceraurinella and Erratencrinurus have not previously been repo
rted from Australia, the former being predominantly Laurentian but also kno
wn from NE China, the Himalaya and Vietnam, and the latter mostly Baltic/La
urentian. Peri-Gondwanan species of Ceraurinella appear to form a clade, wi
thin which Tasmanian and Indian (central Himalayan) taxa are closest relati
ves.
