Provincial Devonian spores from South China, Saudi Arabia and Australia
A spore assemblage from Maoshan, Luquan County, Yunnan Province, South China includes well known Mid Devonian spores includingArchaeozonotriletes variabilis, Cirratriradites monogrammos, Grandispora libyensis, Geminospora lemurata, Cymbosporites magnificus andAncyrospora spp. which constrain the age to Givetian (late Mid Devonian).

Abstract

A spore assemblage from Maoshan, Luquan County, Yunnan Province, South China includes well known Mid Devonian spores includingArchaeozonotriletes variabilis, Cirratriradites monogrammos, Grandispora libyensis, Geminospora lemurata, Cymbosporites magnificus andAncyrospora spp. which constrain the age to Givetian (late Mid Devonian). There are also elements that occur in the Givetian of South Chinaand Australia such as Archaeoperisaccus indistinctus (senior synonym of A. rhacodes) that also occur very rarely in Saudi Arabia. The Maoshanassemblage moreover contains species of Rotaspora. In the Adavale Basin of Australia and Saudi Arabia there is a similar plexus of provincialspecies of Rotaspora but of Emsian age. In addition, there is the morphologically distinct spore Tribojasporites, a genus that was only knownpreviously from the Emsian of Australia. The converse also occurs with spores such as Dictyotriletes biornatus, only previously known from thelate Pragian to mid Emsian of Saudi Arabia, found as rare specimens in Maoshan. This demonstrates that the Maoshan spore assemblage containsspores that are restricted to the northern margin of Gondwana but with younger ranges and represent relict populations that survived in isolationon the South China terrane. Blooms of the hydrodictyacean chlorococcalean alga Musivum gradzinskii previously known only from Poland andSaudi Arabia are also present at Maoshan.
