Talk:Panthalassa

Name

Should this be called Panthalassa or Panthalassa Ocean? I just redirected the latter to the former, as the former is more mature. But our other ancient oceans are named as Tethys Ocean and Iapetus Ocean. Is the former name more commonly used, or should we move the article to the latter, for symmetry with its ancient buddies? -- Finlay McWalter | Talk 21:09, August 4, 2005 (UTC)

Incorrect statement

The first paragraph has a contradiction. The Panthalassa Ocean floor has not completely disappeared. The present day Pacific Ocean is the remnant of the Panthalassa Ocean. It has just been re-named (unfortunately this renaming causes confusion but I think the Panthalassa was named before geologists realized the present Pacific was the same ocean) 98.248.12.159 (talk) 21:43, 25 November 2021 (UTC)

"Life Timeline"

I removed the "life timeline" graphic, as it seems entirely irrelevant to the topic. It includes no mentions or references to Panthalassa- or any other geological/geographic phenomena that appear on the page. If I am missing something, it can be readded, but as is it makes little sense to keep it. 73.92.188.125 (talk) 11:08, 27 November 2024 (UTC)

Incorrect Statements

Removed "In western Laurentia (North America), a tectonic episode that preceded this rifting produced failed rifts that harboured large depositional basins in Western Laurentia. The global ocean of Mirovia, an ocean that surrounded Rodinia, started to shrink as the Pan-African ocean and Panthalassa expanded."

The Pan-African Ocean and Panthalassa did not expand at the same time, the order of superoceans is- in theory, Mirovia, PA Ocean, then Panthalassa.

Due to this order, any geological phenomena related to Mirovia should not be on this page, as Mirovia and Panthalassa didn't exist concurrently. In theory, it is possible to argue that a precursor to Panthalassa existed as Mirovia died- but it is highly tenuous.

I don't really know if the beginning has any basis in fact, as there is no citation-, and due to that, I can't make any proper correction. Due to the inaccuracies at the end, I think it is best to remove it all for now, at least until a proper correction can be made. 73.92.188.125 (talk) 11:35, 27 November 2024 (UTC)

Also removed "Between 650 million and 550 million years ago, another supercontinent started to form: Pannotia, which was shaped like a "V". Inside the "V" was Panthalassa, outside of the "V" were the Pan-African Ocean and remnants of the Mirovia Ocean." for similar reasons.

The Pan-African Ocean was the only one that really existed at that point, as the bifurcate in Pannotia was not significant enough that the water in the center was considered a different ocean, and the "remnants of the Mirovia Ocean" is not a real thing in oceanographic terms.

The "V" shape- as it was stated here, was less upright and more sideways, with total spread of approximately 97 degrees, and so, as stated above, created little to no distinction between the "inside" and "outside" of the "V" oceanographically. It wasn't narrow enough or isolated enough to be defined as a distinct ocean. Panthalassa formed later, somewhat out of this area, upon the formation of Pangea- not the breakup of formation of Pannotia, and certainly not while Pannotia still existed.

The gist of it is that almost everything after "Between 650 million and 550 million years ago, another supercontinent started to form: Pannotia" is either incorrect or built upon previous incorrect information. 73.92.188.125 (talk) 11:57, 27 November 2024 (UTC)
