[1], Under the long-held view that the New Zealand flora has a Gondwanan element that has survived there at least since the Cretaceous, the presence of B. novae-zelandiae in New Zealand can be adequately explained by vicariance. (Before the 2007 transfer of Dryandra into Banksia, it was realised that there was no way to distinguish these two genera based solely on foliar characters, and so fossil leaves were classified into the form genera Banksieaephyllum and Banksieaeformis. Fossil evidence provides clues about how Earth’s landscape has changed over time. Die Pflanzenart Banksia epica gehört zur Gattung Banksia in der Familie der Silberbaumgewächse (Proteaceae).

Fast forward to March 2020 and the Lost World of Bayside team at Museums Victoria found a similar skull segment. This provided evidence that fossils of Banksia were derived from plants growing in fire-free open habitats, thereby indicating that this archetypal member of the fire-dependent Australian flora (He et al., 2011) was not fire-dependent in the past. [contact-form-7 404 "Not Found"] [1], The leaf litter bed in which B. novae-zelandiae was found is regarded as of late Oligocene to early Miocene origin (28 to 16 million years ago), and is thought to have accrued in swamps associated with a coastal delta.

The last million years of Earth history have been characterized by frequent “glacial-interglacial cycles,” large swings in climate that are linked to the growing and shrinking of massive, continent-spanning ice sheets. It shows that the Banksia lineage once occurred in New Zealand , but because the species is regarded as belonging to the stem group, it does not contradict previous evidence suggesting that the crown group of Banksia arose in southwest Australia some time after the Paleogene .

The fossil record of Banksia is among the most extensive of any Australian angiosperm lineage (Carpenter 2012), and Banksieae leaf fossils are of great historical interest with respect to Australian plant-fossil research, being the first Proteaceae leaves with cuticular preservation to be described anywhereintheworld,bythefamousMelbournepalaeobotanist, Alcheringa 7:185-193. BioOne is pleased to announce the 2020 Ambassador Award winners. )[1], Although the cuticular papillae are regarded as evidence that the species belongs to Banksia, their unusual structure, together with some ornamentation of the trichome bases, and the absence of any features of extant Banksia recognised as derived, suggests that B. novae-zelandiae is basal to all extant Banksia species; that is, it belongs to the stem group of Banksia.

Es sind nur zwei isolierte Vorkommen bekannt, beide im westlichen Abschnitt der Großen Australischen Bucht. The common name, ‘Wallum Banksia’, is derived from the Aboriginal term for the species. Comparison with extant taxa shows that the fossils are best regarded as an extinct stem relative of Banksia because their available features are either plesiomorphic for the genus (notably, the stomata are superficially placed, not sunken in balloon-like pits as in many extant species) or lack evidence of synapomorphies that would enable them to be placed in the crown group.
