What's in it

Data offered docs-verified: fossil occurrences (PBDB) · taxon fossil ranges (FAD/LAD) · diversity, origination and extinction curves through geologic time · geologic time scale intervals (named intervals to Ma boundaries) · fossil collections (localities) · bibliographic references for occurrence and collection records
Coverage llm-inferred: Global · roughly 540 million years
Formats docs-verified: MCP stdio · MCP streamable HTTP
Access docs-verified: Free and open. No API key; no auth by default (MCP_AUTH_MODE defaults to none). Server licence Apache-2.0. Resource records carry CC BY 4.0 attribution.

Useful for

Use cases llm-inferred: Palaeontological and geological desk-study screening: fossil occurrences and formations near a proposed site · Dating geological strata for ground investigation scoping by resolving formation and interval ages from the ICS scale · Resolving accepted taxon names and fossil ranges to support ecological or heritage constraint reports
Audience llm-inferred: geologists · palaeontologists · geotechnical engineers · environmental consultants · ecologists

Limitations

Constraints docs-verified: Diversity counts reflect sampling and collection effort, not true past diversity · PBDB accepted taxonomy may differ from the searched name or other taxonomic backbones · Per-call limits: up to 500 records served per call; each response capped at 100,000 bytes · Spill to SQL needs DataCanvas (CANVAS_PROVIDER_TYPE=duckdb); without it, overflowing pages are cut at a next offset · Dataframe tools exist only when DataCanvas is on; the drop tool also needs PALEOBIOLOGY_DATAFRAME_DROP_ENABLED=true · Catalogue tool list omits paleobiology_search_occurrences, which the DOCS list as a core tool · Catalogue auth field says OAuth; DOCS say no auth by default, with OAuth only as an optional server auth mode · Relies on upstream PBDB API availability; no uptime or rate-limit information in DOCS
