Les 8 outils

• paleobiology_dataframe_describe≈ 765 tokens

  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 reference in SQL.

  Paramètres, retour & exemple (1)

  • canvas_id · string · requis
    Canvas id returned by paleobiology_search_occurrences when its result spilled.

• paleobiology_dataframe_query≈ 989 tokens

  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 occurrences by early_interval, group by formation, country (cc), or accepted_name, or filter by a paleo/modern coordinate range. The classification column is JSON — roll up by rank with json_extract_string(classification, '$.family') (also $.phylum, $.class, $.order, $.genus). Staged rows are occurrences, so collection-only fields such as lithology are not present. Reference tables by the table_name that paleobiology_search_occurrences returned — call paleobiology_dataframe_describe first if you do not know the table or column names. A result too large to return inline comes back as its first rows, with a notice naming the ORDER BY … LIMIT/OFFSET that reads the rest. SELECT only; writes and file-reading functions are rejected.

• paleobiology_get_diversity≈ 1578 tokens

  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-inclusive base_name (or base_id, the same clade by resolved taxon id — exactly one of the two) and bound the span by a named interval (e.g. "Mesozoic") or a max_ma/min_ma range; choose what to count (genera, species, or families) and the bin resolution. The full bin set returns inline — a diversity series is a bounded set of geologic intervals — so you read the curve, the turnover, and the per-bin origination/extinction directly. Counts reflect SAMPLED diversity, biased by collection effort and rock availability, not true past diversity.

  Paramètres, retour & exemple (7)

  Paramètres

  • count · string · optionnel · genera | species | families
    What to count per bin: "genera" (default), "species", or "families".
  • max_ma · number · optionnel
    Older bound of the span in millions of years ago. Alternative to interval. When paired with min_ma it must be strictly greater — max_ma is the deeper-time end of the span.
  • min_ma · number · optionnel
    Younger bound of the span in millions of years ago. Alternative to interval. When paired with max_ma it must be strictly smaller — min_ma is the nearer-to-present end of the span.
  • base_id · integer · optionnel
    Clade-inclusive taxon to count, by PBDB taxon id — the taxon_no from paleobiology_get_taxon, or accepted_no on an occurrence row. Same semantics as base_name, but unambiguous where a name is not (homonyms, synonyms, unresolved spellings). Supply this or base_name (exactly one is required, never both).
  • interval · string · optionnel
    Named geologic interval bounding the span, e.g. "Mesozoic". Alternative to max_ma/min_ma.
  • base_name · string · optionnel
    Clade-inclusive taxon to count, e.g. "Dinosauria" or "Ammonoidea" — this taxon and all descendants. Supply this or base_id (exactly one is required, never both).
  • resolution · string · optionnel · period | epoch | age
    Bin resolution: "period" (default, coarse), "epoch", or "age" (finest).

• paleobiology_get_references≈ 1451 tokens

  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, volume, pages, and DOI. Pass the ids from a page of rows in one call: the first 25 distinct ids are resolved and any beyond that come back in remaining_reference_nos for a follow-up call. Ids PBDB has no reference for are listed in not_found. Results keep the order the ids were given.

  Paramètres, retour & exemple (1)

  Paramètres

  • reference_nos · array · requis
    PBDB reference ids to resolve, from the reference_no field of paleobiology_search_occurrences or paleobiology_search_collections rows. Repeats are resolved once. Up to 500 accepted; the first 25 distinct ids are resolved per call.

• paleobiology_get_taxon≈ 1995 tokens

  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) range in millions of years — "when did this clade exist, and what is it." Run this first to resolve a name into the accepted name and taxon_no, then pass that id as base_id to paleobiology_search_occurrences, paleobiology_get_diversity, or paleobiology_search_collections for a clade-inclusive filter that carries no name ambiguity (the same id also appears as accepted_no on occurrence rows). Set show_children to also list immediate child taxa. PBDB taxonomy is opinionated and can differ from GBIF's backbone, so the accepted name may differ from the name you searched.

  Paramètres, retour & exemple (4)

  Paramètres

  • name · string · optionnel
    Taxon name to resolve, e.g. "Tyrannosaurus" or "Ammonoidea". Provide this or taxon_no.
  • taxon_no · integer · optionnel
    PBDB taxon id from a prior get_taxon, or accepted_no on an occurrence row. Provide this or name, never both.
  • show_children · boolean · optionnel
    When true, include a page of the immediate child taxa of this taxon (at most 200 per call — children_truncated says whether more remain).
  • children_offset · integer · optionnel
    Number of immediate children to skip before the returned page — used only when show_children is true. Advance it by 200 while children_truncated is true to walk the whole child list.

• paleobiology_list_intervals≈ 1530 tokens

  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 filter on the other tools and translates a named interval like "Late Cretaceous" to its 100.5–66.0 Ma boundaries (and back). Filter by a name substring, a Ma range (overlap match), and/or a level; call with no filters to browse the full scale. Browsing and every name on the bundled ICS international-scale snapshot are answered offline. A name the snapshot does not carry — the sub-stage and regional names that occurrence and collection rows report, such as "Late Maastrichtian" or "Lancian" — costs one PBDB lookup across its other time scales; the response names which source answered and which scale the interval belongs to.

  Paramètres, retour & exemple (4)

  Paramètres

  • name · string · optionnel
    Case-insensitive substring of the interval name, e.g. "cretaceous" or "Jurassic". A name the bundled international scale does not carry is matched exactly against PBDB's other time scales.
  • level · string · optionnel · eon | era | period | epoch | age
    Restrict to one rank of the international scale: eon, era, period, epoch, or age (finest). Browsing is bounded to that scale, so the sub-stage and regional ranks are not selectable here.
  • max_ma · number · optionnel
    Older bound of an age window (Ma); intervals overlapping [min_ma, max_ma] match. When paired with min_ma it must be greater than or equal to it — equal bounds name a single point in time.
  • min_ma · number · optionnel
    Younger bound of an age window (Ma); intervals overlapping [min_ma, max_ma] match.

• paleobiology_search_collections≈ 2315 tokens

  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, lithology, depositional environment, and the count of co-occurring fossils. Filter by a clade-inclusive base_name (or base_id, the same clade by resolved taxon id), a named interval or max_ma/min_ma range, a lng/lat bounding box, a formation or lithology name, and/or an environment. Results page inline via limit/offset (the response discloses when more remain). Take a collection_no from a row and pass it — or the same bbox+interval — to paleobiology_search_occurrences to see the actual fauna found together.

  Paramètres, retour & exemple (14)

  Paramètres

  • limit · integer · optionnel
    Maximum localities to return per page. Up to 500 are pulled per call; a larger value is served at 500, and the paging notice names that cap when more matches remain. A page can show fewer rows than it pulled when more would exceed the inline response size — the notice then names the offset that continues.
  • latmax · number · optionnel
    Northern edge of the bounding box, decimal degrees (−90…90). Valid on its own — a lone latitude edge filters as a half-plane.
  • latmin · number · optionnel
    Southern edge of the bounding box, decimal degrees (−90…90). Valid on its own — a lone latitude edge filters as a half-plane.
  • lngmax · number · optionnel
    Eastern edge of the bounding box, decimal degrees (−180…180). Longitude is a closed pair — supply lngmin with it or neither.
  • lngmin · number · optionnel
    Western edge of the bounding box, decimal degrees (−180…180). Longitude is a closed pair — supply lngmax with it or neither.
  • max_ma · number · optionnel
    Older age bound in millions of years ago. When paired with min_ma it must be strictly greater — max_ma is the deeper-time end of the window.
  • min_ma · number · optionnel
    Younger age bound in millions of years ago. When paired with max_ma it must be strictly smaller — min_ma is the nearer-to-present end of the window.
  • offset · integer · optionnel
    Number of localities to skip — page with limit by advancing offset.
  • base_id · integer · optionnel
    Clade-inclusive taxon filter by PBDB taxon id — the taxon_no from paleobiology_get_taxon, or accepted_no on an occurrence row. Same semantics as base_name, but unambiguous where a name is not (homonyms, synonyms, unresolved spellings). Supply this or base_name, never both.
  • interval · string · optionnel
    Named geologic interval bounding the age, e.g. "Maastrichtian". Alternative to max_ma/min_ma.
  • base_name · string · optionnel
    Clade-inclusive taxon filter — localities yielding this taxon or its descendants, e.g. "Dinosauria". Supply this or base_id, never both.
  • formation · string · optionnel
    Geologic formation name to filter by, e.g. "Hell Creek".
  • lithology · string · optionnel
    Lithology (rock type) to filter by, e.g. "sandstone".

• paleobiology_search_occurrences≈ 3498 tokens

  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" usually means), base_id for that same clade by resolved taxon id, or taxon_name for an exact taxon. Bound the age by a named interval (e.g. "Maastrichtian") or a max_ma/min_ma range, and/or a lng/lat bounding box; scope to a single locality with collection_no (take it from a paleobiology_search_collections row). At least one filter is required — taxon, time, place, environment, or collection_no. Every row carries two distinct coordinate systems — modern lng/lat (where the rock is today) and paleo lng/lat (where the landmass sat at deposition) — plus the formation, age interval, and higher classification (phylum through genus); never plot a deep-time occurrence on a modern coastline. Resolve a name with paleobiology_get_taxon first if unsure. Broad queries return many rows: an inline preview answers the immediate question. When this deployment has DataCanvas enabled, a set that outgrows the inline preview stages on a canvas (canvas_id + table_name, returned only then): list its columns with paleobiology_dataframe_describe, then run SQL with paleobiology_dataframe_query (count by interval, group by formation/country, map by region). The response reports how many occurrences matched in total, which rows this page covers, and the offset that reaches the next page — page through the whole match set with limit/offset.

  • canvas_id · string · optionnel
    Canvas id from a prior call to re-stage onto the same workspace. Used only when this page spills: reusing it REPLACES (overwrites) the prior occurrence table — each search restages the full result, it does not append to or accumulate across earlier ones — while a page that fits inline leaves that canvas untouched. Omit to start fresh; a spilled response returns a new id.
