Trzeciorzdowe
Trzeciorzdowe is not a term that appears in widely recognized reference works, and there is no established article for it in major encyclopedias. The closest common form in Polish is trzeciorzędowe, an adjective related to trzeciorzędowy, meaning tertiary. In that sense, if Trzeciorzdowe were intended to refer to geology, it would pertain to the Tertiary period, a subdivision of the geologic timescale dating roughly from 66 to 2.6 million years ago and associated with various rock formations and paleontological finds. Terms like skały trzeciorzędowe (tertiary rocks) occur in geological contexts, often in discussions of stratigraphy and evolutionary history.
Alternatively, Trzeciorzdowe could be a toponym, such as a place name in a Polish-speaking region or elsewhere.
A further possibility is that Trzeciorzdowe appears in a fictional work, a specialized vocabulary in a niche
