paleobiology_search_occurrences

Search fossil occurrences filtered by taxon, geologic time, geography, and depositional environment — the flagship. Use base_name for a clade and all its descendants (what "Tyrannosaurus occurrences" …

paleobiology_get_taxon

Resolve a taxon by name (e.g. "Tyrannosaurus") or by integer taxon_no to its accepted name, rank, higher classification, immediate parent, fossil occurrence count, and first/last appearance (FAD/LAD) …

paleobiology_get_diversity

Compute a diversity / origination / extinction curve for a clade across geologic time, binned by period, epoch, or age — answers "plot dinosaur genus diversity across the Mesozoic." Pass a clade-inclu…

paleobiology_list_intervals

Look up the geologic time scale — eons, eras, periods, epochs, and ages with their absolute-age boundaries in millions of years (Ma) and nesting. This is the reference that grounds every temporal filt…

paleobiology_search_collections

Find fossil collections (localities) by area and geologic time — "what has been dug up here, and from what rock." Each locality returns its location, age (named interval and Ma), formation and strata,…

paleobiology_get_references

Resolve PBDB reference_no values — the source publication on every paleobiology_search_occurrences and paleobiology_search_collections row — to full citations with authors, year, title, publication, v…

paleobiology_dataframe_query

Run a read-only SQL SELECT against occurrence result sets staged on a DataCanvas by paleobiology_search_occurrences. This is how you analyze a large fossil set without re-fetching it: count occurrence…

paleobiology_dataframe_describe

List the tables and their columns staged on a DataCanvas by paleobiology_search_occurrences. Call this before paleobiology_dataframe_query to discover the exact table_name and column names to referenc…
