All 363 units with every field, plus dataset metadata. Best for developers and APIs.
One row per unit, UTF-8 with BOM. Opens cleanly in Excel, Google Sheets, R or pandas.
159 units with a resolved type-locality point. Drop into QGIS, Leaflet or kepler.gl.
Use offline
This site already works offline for pages you’ve opened. Save the whole reference to your device — every unit, period and province page — so it’s available in the field with no signal.
Downloads a few megabytes of pages. Re-run after a site update to refresh. Needs a browser that supports service workers.

The JSON keeps arrays as arrays; the CSV joins multi-value fields (provinces, fossils, synonyms) with a semicolon. lat/lng are decimal degrees, parsed from the recorded type-locality where a coordinate exists.
