Was the northern arm called the Sundance Sea before it merged with the transgression from the Gulf of Mexico? 68.81.231.127 06:38, 13 Jan 2005 (UTC)
Good question.... does somone know? Wendell
Don't think so...I'm pretty sure the Sundance Sea had regressed and been filled with eroded sediments well before the trangression that created the Western Interior Seaway began. Erimus 21:36, 17 June 2006 (UTC)
Could someone provide some references to the timescales involved here? I realize the late-Cretaceous Period is mentioned, but I think some actual dates would be helpful. — Preceding unsigned comment added by JefeMixtli ( talk • contribs) 17:30, 12 February 2011 (UTC)
How much conceptual overlap is there between the idea of the Colorado Sea and the Western Interior Seaway? Abyssal ( talk) 16:48, 7 April 2011 (UTC)
This sea has been nicknamed Hell's Aquarium due to the sheer quantity and diversity of large predatory reptiles and fish that called it home. Is this noteworthy enough to be mentioned in the article?-- Dinolover45 ( talk) 16:53, 1 October 2012 (UTC)
the large-scale, regional uplift, which raised the Rockies & Great Plains, seems to be termed Epeirogenic uplift. 66.235.38.214 ( talk) 12:44, 31 October 2012 (UTC)
Whomever edited references here and in some other areas has invented a person, Benton. The article citation should read "Bennett, S. C. The pterosaurs of the Niobrara Formation. The Earth Scientist, 11(1):22-25." — Preceding unsigned comment added by 209.114.104.7 ( talk) 18:48, 13 January 2014 (UTC)
This shows the western Interior seaway disappearing between 70-66 mya.These are mine. I modeled them using a United states map. I can add canada and Mexico
Western Interior Seaway disappearing between 70-66 mya I used these images.
The Colorado Department of Transportation did a Paleo excavation next to I -25 at Castle Rock Colorado and got 135 new species of tree leaves with drip tips at 64 Ma. The Climate was above water, and wet as the drip tips on the leaves indicate a location with high rainfall, and high humidity. There are also petrified trees found near Lincoln Avenue east of I - 25 , a few miles south of Denver. The time period was similar. Swampy, coastal, jungle, lots of rain and around 64 Ma.
Look at the Scotese Videos to see roughly when the water left the continent. I suspect it took a longer time getting to maximum elevation, and a shorter time leaving the continent. 98.245.216.62 ( talk) 22:04, 6 March 2022 (UTC)
The article contains a very nice map of the Skull Creek Seaway. There is, however, no explanation of how this seaway relates to the Western Interior Seaway, nor is there a Skull Creek Seaway article. In fact, other than this map a single sentence in the next-to-last paragraph of the Tenontosaurus article seems to be the only mention of the Skull Creek Seaway in all of Wikipedia. Perhaps someone could fix this.... 71.235.184.247 ( talk) 03:30, 28 July 2018 (UTC)

I did an estimated calculation of when the Western Interior Seaway reached its maximum water elevation, and depth and came up with an approximation of 89.5 Ma. When looking at the Scotese Videos, it shows around 84.0 Ma. Has anyone done any work on when the Maximum elevation and depth of the water was reached? — Preceding unsigned comment added by 98.245.216.62 ( talk) 21:51, 6 March 2022 (UTC) 98.245.216.62 ( talk) 22:09, 6 March 2022 (UTC)
Maximum transgression (Fig. 22) is represented by relatively pure pelagic carbonates of the Jetmore and Pfeifer Members of the Greenhorn; for this reason the sequence was named Greenhorn cyclothem by Hattin (1962, p. 124).
