Holotype: Fossil Identifier
Identify a fossil, date it and catalogue it like a museum
Holotype identifies fossils from a photo and turns each find into a catalogued specimen. It places your collection on a geologic timeline, gives every saved find its own catalogue number, keeps the field data a curator would ask for and prints a classic museum-style specimen label.
What it does
AI fossil identification
Identify a fossil from a camera photo or a picture in your library: taxon, age range, environment and how it lived.
Geologic timeline
Your home screen places every saved find in its period, from the Precambrian to the Quaternary, with the empty periods left visible.
Catalogue numbers and field data
Each specimen gets a permanent catalogue number (HT-0001 and on). Record formation or bed, locality, date collected, collector, dimensions, preparation and field number.
Museum-style labels
Turn a specimen into a classic natural history label and share it as an image or PDF, or print a sheet of labels with cut lines on A4 or US Letter.
Personal collection
Keep notes, voice notes, tags, favorites, albums and an optional find location with each specimen.
Export and import
Export the whole catalogue as CSV, JSON or PDF, and import a JSON file again.
