Dear Laura,
In CSIC we use the International Chronostratigraphic Chart as well. Following this chart, and using the Excel file sent by Steffen Kiel, I am attaching the proposed standard that CSIC is talking about, with ID in the whole chart.
Best wishes,
Celia

Hi Laura,
I fully agree with Björn and Jiri that a detailed and hierarchical timescale is essential. Attached is an example that we use at NRM PAL. The numerical ages are a few years old but should mostly be correct. And they can be used for sorting or validation; i.e., if a range of ages is given, the upper stage should not be allowed to be older than the lower stage.
Cheers, Steffen

Dear Laura,
same here. The international and official valid scale for chronostratigraphy is here. http://stratigraphy.org/index.php/ics-chart-timescale
Indeed especially column Stage/age is important in combination with local Lithostratigraphy units, this is usually the most important information related to specimen localisation. (together with locality and taxonomy).
Best regards,
Jiri

Hello Laura,
I am not 100% sure what for these categories are needed and why there is some constraint for the number of categories. But properly defined global chronostratigraphic units are the only choice and I would also go for a hierarchical solution with codes for e.g. the Mesozoic unspecified and then lower in the hierarchy toward the periods. The latest international standard can be found here: http://stratigraphy.org/index.php/ics-chart-timescale
Kind regards,
Björn

Subject: [CETAF_ESG] Advice need: about how earth science collections defined stratigraphically in institutions.
Dear colleagues,
I am writing to ask for some advice on how I should define the stratigraphic levels for the SYNTHESYS+ Collections Digitisation Dashboard. I have attached an excel sheet with classification of Stratigraphy from the ICEDIG project (sheet 1 in black ink) – I have added some categories in red – but I think there are too many to be filled in. Could Precambrian material be lumped together?
I would like to ask do we need that many categories really? – based on how earth science collections are categorised in institutions.
Do you have any insight into how Earth Science collections are classified?
I need to add a category for unknown.
In sheet two, CSIC Madrid has given an alternative classification.
I would be grateful for any feedback before the end of this week.
Best wishes
Laura
