yes. i adapted a [Jupyter notebook that i’ve been working on](https://forum.inaturalist.org/t/whats-the-best-way-to-share-python-code-nowadays/48554), with the following changes:

1. uncomment (remove the leading `#` from the) lines that begin with:
  - `{'label': 'ident_taxa_vs_prev_ancestor'` (allows you to find identifications that were an ancestor to the observation taxon at the time of ID)
  - `{'ref': 'place_ids'}` (allows you to get standard place names)

2. modify the following lines:
  - `req_params_string = 'spam=false&taxon_id=58573&ident_taxon_id=54068&created_d2=2023-03-10'` (look for taxon Bolonia, with an identification of B. selene, created before the change date)
  - `obs = await get_obs(req_params, get_all_pages=True, use_authorization=False, post_parse_filter_function=(lambda x: x['ident_taxa_vs_prev_ancestor'] > 0))` (get all records, applying a client-side filter for identifications which were ancestors to the obs taxon at the time of ID)

3. run
