Etymology: Micropalaeontology is a compound built from two parts that were each coined or borrowed separately. The first, "micro-", comes from the Ancient Greek "mīkrós", meaning "small," and it has been used as a combining form in English for scientific compounds. The second part, "palaeontology", is the study of ancient life through fossils, itself formed from Greek roots meaning "ancient," "being," and "discourse." Put together, the word describes the study of fossils too small to see without a microscope. Many of these are the shells or skeletons of single-celled organisms such as foraminifera and diatoms, which accumulate in enormous numbers on sea floors and can be used to date rock layers and reconstruct past environments. The spelling "micropaleontology", with an e instead of the ae, is the American form of the same word, and both spellings appear in English usage.

Synonyms: micropaleontology
