Timing of final break-up[edit]

For most sources, the final break-up occurred at or about the end of the Paleocene, ~55 Ma. There are some, however, that reckon it shouldn't be regarded as full separation until spreading had stopped west of Greenland, at about 34 Ma, e.g. here although from the early Eocene opening along the Mohns and Gakkel Ridges there was arguably a continuous plate boundary, even if there was continental crust either side of it, where Svalbard was adjacent to NE Greenland.

Mikenorton: I found another ref that gives a slightly different version, but feel free to add to it. --Fama Clamosa (talk) 13:21, 1 December 2019 (UTC)[reply]

Seton et al state "The establishment of a three-plate system between North America, Eurasia/Rockall and Greenland occurred after Anomaly 25 (~56 Ma)", so at that point the break-up had been achieved in my view. Mikenorton (talk) 13:52, 1 December 2019 (UTC)[reply]

Archive talk?[edit]

Page has been rewritten now and most of the comments are outdated. Should we archive manually? --Fama Clamosa (talk) 19:06, 13 January 2020 (UTC)[reply]

Apologies, but this or any related articles does not inform how it was proven as truth. Everything is just a theory so why does the Wikipedia article pose as a scientific fact? Danraz (talk) 06:42, 17 May 2020 (UTC)[reply]

Merger proposal[edit]

I propose to merge Euramerica into Laurasia#Laurussia or possibly Laurasia#Terminology and origin of the concept. Various names and concepts are better explained in Laurasia now and Euramerica is a short article and have been so for a long time. --Fama Clamosa (talk) 12:26, 12 April 2020 (UTC)[reply]
