Oxygen levels.

I think that they're incorrect. Asking wolfram alpha gives you a much lower percentage, by half a lower than what they are today. And WolframAlpha has reputable references. — Preceding unsigned comment added by 91.148.87.143 (talk) 21:13, 23 April 2014 (UTC)

end of the Jurassic

I am trying to find something on the minor mass extinction that ended the Jurassic but it doesn't seem to be on wikipedia. — Preceding unsigned comment added by 82.41.41.184 (talk) 21:24, 14 June 2014 (UTC)

Does not match the chart I found?

The start and end of the Jurassic period does not match the information on this chart I found, as well as the other periods. How can this be? The chart I found is here: http://www.geelongaustralia.com.au/library/images/inpage/gbglivingfossilstimeline.gif — Preceding unsigned comment added by 174.61.229.206 (talk) 16:55, 31 May 2015 (UTC)

Someone please fix the vandalized images

I think it's done through a template maybe? I don't know how, or I'd do it. Thanks. — Preceding unsigned comment added by 67.200.225.18 (talk) 18:07, 28 November 2017 (UTC)

Timeline is messed up

I was looking at the page in mobile, and the timeline is all messed up, there is a loooong piece of code instead of that. Please fix the issue. Same on desktop view as well. --Yogeeta4 (talk) 07:18, 19 April 2019 (UTC)

Thanks for reporting this problem. The formatting problem seems to have been fixed by an edit at 09:46 on 19 April 2019: https://en.wikipedia.org/w/index.php?title=Template%3AJurassic_graphical_timeline&action=historysubmit&type=revision&diff=893146748&oldid=893133937 GeoWriter (talk) 14:42, 20 April 2019 (UTC)

Please let's put ourselves in the reader's shoes...

After recent modifications were brought, the article reads Thirty years later, when the French naturalist Alexandre Brongniart published his book in 1829, bla bla bla. "His book"? what book? Did he write only one book in his entire life? Please let's put ourselves in the reader's shoes: now that sentence not only makes no sense, it simply gives deceptive impressions to the reader. It is obvious that the title of the book that coined the term Jurassique for the first time in history should be quoted in the article, both in French and English.

It's ok, now the wording is quite satisfactory to me. Kintaro (talk) 15:36, 19 May 2019 (UTC)

Timing question

Triassic states that it "spans 50.6 million years from the end of the Permian Period 251.9 million years ago (Mya)", while Jurassic states that it "spanned 56 million years from the end of the Triassic Period". Which is correct: 56, or 50.6? Thanks – ClockworkSoul 13:43, 1 June 2020 (UTC)

Both dates are different, and refer to the length of the Triassic and Jurassic respectively. Hemiauchenia (talk) 21:13, 5 December 2020 (UTC)
