Template-protected edit request on 14 January 2023

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

I am requesting an edit to this template because, once again, some of the boundaries of the time periods have been changed. This new data comes from the International Commission on Stratigraphy's latest rendition of the geologic timescale: [1], Changelog: [2]

The changes are:

Tithonian from 152.1 to 149.2
Kimmeridgian from 157.3 to 154.8
Oxfordian from 163.5 to 161.5
Callovian from 166.1 to 165.3
Bathonian from 168.3 to 168.2
Bajocian from 170.3 to 170.9
Aalenian from 174.1 to 174.7
Toarcian from 182.7 to 184.2
Pliensbachian from 190.8 to 192.9
Sinemurian from 199.3 to 199.5
Hettangian from 201.3 to 201.4
Hadean from ~4600 to 4567

The Hadean change is explained in the provided changelog, in case it seems weird. I've already updated the sandbox with these dates, and I will update the uncertainties on Template:Period start error and Geologic time scale. Benniboi01 (talk) 18:49, 14 January 2023 (UTC)[reply]

@Primefac, I made a mistake with the Hadean GSSA. The Hadean age is actually 4567.3, not 4567. Could you fix it? I can submit another request if needed. Benniboi01 (talk) 18:08, 16 January 2023 (UTC)[reply]

Done. Primefac (talk) 11:24, 17 January 2023 (UTC)[reply]

Description of suggested change: Update to ICC v2023/06

Two minor changes to dates in this update. Langhian from 15.97 to 15.98, and Barremian from ~129.4 to 125.77. Changed in the sandbox and appears to be working correctly in the test cases.

A new timescale came out a few days ago with the archean GSSA updated. For the line that reads:

| eoarchean | isuan = 4000

replace it with:

| eoarchean | isuan = 4031

Thank you! Benniboi01 (talk) 03:16, 30 October 2023 (UTC)[reply]

update to ICC v2024/12

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

Description of suggested change: The ICS has recently released the December 2024 revision of the International Chronostratigraphic Chart. I've edited this template's sandbox page in accordance with ICC v2024/12, and I request for the sandbox update to be brought over to the template as a whole. Many of the updates are minor, though a few stages (Wuliuan, Rhaetian, Tithonian, etc.) have received more substantial alterations in their start estimates. I also removed a few outdated tags; for example, the ICC now labels lower/middle/upper Miocene, so tags indicating otherwise are no longer necessary. NGPezz (talk) 02:49, 2 January 2025 (UTC)[reply]

NGPezz, can I just verify that the sandbox only contains edits you want to be merged into the main template? (please do not ping on reply) Primefac (talk) 09:54, 2 January 2025 (UTC)[reply]

Yes, after double-checking the test cases page I can confirm that the state of the sandbox (as of the current revision) is what I intend for the main template. NGPezz (talk) 17:54, 2 January 2025 (UTC)[reply]
