Fossilia helps you identify fossils and rocks from a photo—and tells you when what you found isn't a fossil at all. Take a picture with your camera or pick one from your gallery to see the most likely match, two alternative candidates, and an estimated value.
Take a picture with your camera or pick one from your gallery. Fossilia analyzes the image and suggests the most likely match, with two alternative candidates, so you can see what else it could be instead of a single confident guess
Most things people photograph aren't fossils, so Fossilia decides that question first, before naming anything. A concretion, a manganese dendrite, a septarian nodule, a flint nodule, a water-worn pebble, or a modern shell is called what it is, along with what people usually mistake it for—and no price is shown. A rock with a price tag on it helps nobody
Every reason listed is something visible in your own photo—the stacked discs, the fracture surface, the pore pattern—so you can hold your specimen up and check the answer instead of taking it on faith. Results include the common name, a scientific name at the rank the photo actually supports, geologic period and age, rarity, preservation and matrix, and where this kind of specimen typically comes from
A photograph carries no scale, and size is what separates crinoid stems from Orthoceras, or a concretion from an egg. Pick a size band before you scan—no measuring required—and it's used for both the identification and the price. Your measurement is always labeled as yours
For identified fossils, Fossilia provides a value estimate informed by current marketplace listings of similar specimens, and shows you those comparable listings so you can see the market for yourself. Common material is called common: plenty of real fossils are worth a few dollars, and you'll be told that plainly
Saved specimens are arranged into a stratigraphic column from the Quaternary down to the Precambrian. Empty periods are drawn too, so you can see which stretches of time your collection is still missing
Beaches, creek beds, quarries, road cuts, and spoil heaps
The drawer of rocks from childhood, an inherited collection, a shelf of unlabeled specimens
Rock and mineral shows, flea markets, estate sales, and online listings
Anyone who wants to know what they just picked up
Photograph what you found and get an answer you can check against the specimen in your hand—the name, the period it came from, what it's worth, and whether it's a fossil at all.
