<meta content="Oligocene-Early Miocene macrofossils of parts of a fertile frond are assigned to the extant South American species Lophosoria quadripinnata (Gmel.)C.Chr. These macrofossils bear the dispersed spore species Cyatheacidites annulatus Cookson ex Potonie. This species has an extensive recorded history in the Southern Hemisphere, only recently retracting to its current range. This history suggests major episodes of expansion and extinction, with a double extinction occurring in Australia and Cenozoic introductions to the Kerguelen Islands and the Falkland Plateau that probably involved transoceanic dispersal. Cretaceous Lophosoria records may or may not include L. quadripinnata, but they probably included several species, especially in the southern South America-Antarctic Peninsula region, where other dispersed spore species of Cyatheacidites and the macrofossil species L. cupulatus are recognised. This species diversity probably collapsed during the Cretaceous, possibly due to angiosperm radiation. The Cenozoic record of C. annulatus in Australia appears to represent a radiation of L. quadripinnata, probably from South America." name="eprints.abstract" />

These macrofossils bear the dispersed spore species Cyatheacidites annulatus Cookson ex Potonie. This species has an extensive recorded history in the Southern Hemisphere, only recently retracting to its current range. This history suggests major episodes of expansion and extinction, with a double extinction occurring in Australia and Cenozoic introductions to the Kerguelen Islands and the Falkland Plateau that probably involved transoceanic dispersal. Cretaceous Lophosoria records may or may not include L. quadripinnata, but they probably included several species, especially in the southern South America-Antarctic Peninsula region, where other dispersed spore species of Cyatheacidites and the macrofossil species L. cupulatus are recognised. This species diversity probably collapsed during the Cretaceous, possibly due to angiosperm radiation. The Cenozoic record of C. annulatus in Australia appears to represent a radiation of L. quadripinnata, probably from South America.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">The definitive version is available online at http://www.sciencedirect.com/</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">Lophosoria, biogeography, Southern Hemisphere, Cretaceous, Cenozoic</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/260112.html">260000 Earth Sciences > 260100 Geology > 260112 Palaeontology</a><br /><a href="http://eprints.utas.edu.au/view/subjects/270401.html">270000 Biological Sciences > 270400 Botany > 270401 Plant Systematics, Taxonomy and Phylogeny</a><br /><a href="http://eprints.utas.edu.au/view/subjects/270709.html">270000 Biological Sciences > 270700 Ecology and Evolution > 270709 Biogeography</a><br /><a href="http://eprints.utas.edu.au/view/subjects/260113.html">260000 Earth Sciences > 260100 Geology > 260113 Palynology</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">1763</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">dr gregory j jordan</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">03 Sep 2007</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">09 Jan 2008 02:30</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=1763;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&eprintid=1763">item control page</a></p>
