- Silurian (adj.)
[Silurian 词源字典]
- 1708, "pertaining to the Silures," from Latin Silures "ancient British tribe inhabiting southeast Wales." Geological sense is from 1835, coined by Sir Roderick Impey Murchison (1792-1871) because rocks of this period are especially frequent in Wales.[Silurian etymology, Silurian origin, 英语词源]
