Etymology: Biolithite is a technical coinage rather than an ancient or folk word. It is built from the Greek "bios" (life) and "lithos" (stone), the same classical building blocks that geologists and palaeontologists drew on throughout the nineteenth and twentieth centuries to name new kinds of rock and fossil. The first element appears in many modern scientific terms, such as "biology" and "biosphere", while "-lite" comes from the Greek "lithos" and was standardised in English as the ending for rock names, as in "monolith" and "laterite." The term describes rock that is made up largely of the remains of living things, such as shells, skeletons and plant fragments, which settle and compact over time. The Greek roots tell you the core idea: life made stone. Because the word is a modern descriptive label, it does not carry a long history of use, and its exact dating and first appearance in print would need to be checked against a dictionary such as the OED before being stated as fact.
