What does zoolite mean?
Zoolite is a chiefly historical geological term for a mineral occurring in calcareous rocks and consisting chiefly of fossil remains of animals. Its name combines the Greek roots for “animal” and “stone,” making it especially memorable because it describes a literal stone containing traces of once-living creatures. Zoolite can include fossilized shells, coral, bones, and other animal remains preserved in sedimentary rock, particularly limestone. In older scientific writing, it functioned as a broad descriptive term rather than the name of a single modern mineral species. It should not be confused with zeolite, which denotes a group of crystalline aluminosilicate minerals with entirely different origins and properties. Although uncommon in everyday language, zoolite remains useful in the history of geology and palaeontology because it records how animal remains become incorporated into stone and how such fossils can help reconstruct ancient environments.
nounA chiefly historical geological term for a mineral occurring in calcareous rocks and consisting chiefly of fossil remains of animals.
- A mineral occurring in calcareous rocks and consisting chiefly of fossil animal remains.
"The quarry exposed a layer of zoolite containing fossilized shells and coral."
"The museum displays specimens of zoolite collected from chalk formations."
"Shell fragments preserved in the zoolite provide evidence of the area's marine history."
The plural is zoolites, though the word itself is now uncommon.
"Several zoolites from chalk beds were catalogued by the museum."
Zoolite literally means “animal stone”: a fossil that preserves a trace of ancient life.

Etymology of zoolite
Zoolite combines the Greek zōion, meaning “animal” or “living being,” with lithos, meaning “stone.” The compound was used in early modern geological writing for fossil animal material or mineralized animal remains. Its elements also appear in words such as zoology, which concerns animals, and lithology, which concerns the study of rocks.
How zoolite is actually used
The word is rare, technical, and largely historical. It appears chiefly in older geological and palaeontological literature rather than in modern mineral classification.
Easily confused with zoolite
Zoolite refers to animal remains in stone, whereas a zeolite is an aluminosilicate mineral associated with the Greek word for boiling.
