[edit] Supernova
What is the significance of the supernova(e) discussion? Do we have evidence that there was a mass extinction of oceanic fauna and, if so, can we attribute it to this more certainly than we can to the general cooling of the world's oceans? Would these supernovae also have resulted in extinctions amongst terrestrial fauna or would they have been somehow protected (and, if so, how)? While it is interesting to speculate on the existence of the supernova(e), if there is no information to tie them to significant ecological changes in the Pliocene epoch, should they be here? If that information does exist, why is it not listed here in the stead of this vague and mostly speculative section?
[edit] AMK152's Geotimeboxes
AMK152 proposed in edits of 27 December 2006 a geotimebox for this article as follows:
| Eon: | Proterozoic • Phanerozoic • [[]] |
| Era: | Mesozoic • Cenozoic • [[]] |
| Period: | Paleogene • Neogene • [[]] |
| Epoch: | Miocene • Pliocene • Pleistocene |
I feel that the box information that is appropriate for the article is already in the footer, and that other extraneous information, such as previous eons, can be supplied where important, by links from the text. I removed the geotimebox and left the footer, pending discussion. --Bejnar 23:26, 27 December 2006 (UTC)
[edit] Mammals
"The marsupials remained the dominant Australian mammals, with herbivore forms including wombats and kangaroos, and the huge diprotodonts." Article diprotodont contradict this. - phe 19:40, 10 January 2008 (UTC)
I have some questions about the climatology and the paleogeography sections: First of all, the ice is described at spreading across Antarctica during the Pliocene. Then, the statement is made that the whole continent is iced in by the begining of the Pliocene. Is this really supposed to say the begining of the Pleistocene? That would make a lot more sense. Secondly, in paleogeography, the Mediterranean Sea is described as being formed in the Pliocene when Africa bangs in to Europe. But the Med had to already be there during the Miocene or there never would have been a Messinian Salinity Crisis. Or did it? Dre William (talk) 03:18, 29 April 2008 (UTC)
