Talk:Pliocene

From Wikipedia, the free encyclopedia

Pliocene is included in the 2006 Wikipedia CD Selection, or is a candidate for inclusion in the next version. Please maintain high quality standards and, if possible, stick to GFDL-compatible images.

[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)
