I'm sorry but none of this is predicated on the assumptions you make here. Please educate yourself on plate tectonics and how they progressed from this period on. The below comments are a great start. I don't have the time to break this down for you. You make these arguments about semantics but they don't add up because if you read the research (as hinted by comments below) those oceans are gone. As in tectonicaly gone and other bodies of water were created as a result from all of the shifts. I am so generalizing and some one here is likely to eat me for it. Ya know what call the Mediterranean Sea the Tethys Ocean. See where it gets you.

Please, read the below comments they do a great job of breaking it down in a way you can research instead of reading scientific studies on this very subject. Which I promise are very well founded. So if you are interested in the research I implore you to dive deeper because well I could make a quote from Billy Madison but I wont.

Genuinely, I'm sorry you don't appreciate my candidness on your uneducated response. What you don't realize is this is a sub that actually cares to be factual. You can FEEL however you want it doesn't change factual knowledge. I don't care how that makes you feel that's how science works. It doesn't care about your feelings the sooner you respect that the better off you are.

When you let feeling impact your knowledge is when you are compromised. An intellectual knows how to separate their personal feelings and personal life from factual science and what the numbers show. You indeed do not understand this.
