noun
natural history specimen
Refers to preserved specimens of plants, animals, minerals, etc., used for scientific study or display in museums.
博物館には貴重な博物標本が展示されている。
Valuable natural history specimens are on display at the museum.
標本 is a broader term for any specimen or sample, while 博物標本 specifically refers to specimens in the context of natural history.
Compound of 博物 (natural history) and 標本 (specimen). The exact historical derivation is uncertain, but the term is a straightforward combination of these two Sino-Japanese words.
