Deep time
93% of the catalog is fossil.
Foraminifera leave a near-continuous record across hundreds of millions of years. Most of what we catalog is extinct — and synonymy is preserved, never discarded: 27,577 historical names reconciled to their accepted taxa.

Provenance & interoperability
Every record carries its source
Nothing enters the catalog without a citable origin, and every taxon is keyed to standard registries — so the data is reusable far beyond this site.
The morphological matrix
A character key, built and waiting
Identification turns on observable characters. The key is fully defined — 14 characters, 49 states — and almost entirely unscored. Each filled cell below is one recorded observation; the empty rows are the open invitation.
