/mᵻˈniːvɪən/, U.S.

Forms: 1800s Maenevian, 1800s Minevian, 1800s– Menevian.

Origin: a borrowing from Latin, combined with an English element. Etymons: Latin Menevia , -an suffix.

1865 J. W. Salter & H. Hicks in Rep. Brit. Assoc. (Hardwicke) 147 The authors propose the term ‘Minevian’ [1866 main report: ‘Menevian’] for the lowest division of the ‘Lingula flag’.

1865 J. W. Salter & H. Hicks in Q. Jrnl. Geol. Soc. 21 477 The new term ‘Mænevian Group’.

1882 A. Geikie Text-bk. Geol. 654 The Menevian beds.

1946 H. Woods Palæontol. Invertebr. (ed. 8) 49 The earliest British form is Protospongia from the Menevian Beds and Lingula Flags.

1969 G. M. Bennison & A. E. Wright Geol. Hist. Brit. Isles iv. 80 It [sc. the Caerfai Series] is followed by the Solva and Menevian Series of Middle Cambrian age.

1995 Science 20 Jan. 355/3 Bentonite sample RJM536 is from the Middle Cambrian Menevian Beds with a depositional age of 517 to 530 Ma.

1871 Amer. Naturalist 5 476 These lower rocks in Wales contain an abundant fauna, extending downwards some 2800 feet from the Menevian to the very base of strata regarded as the representatives of the Harlech grits.

1894 Geol. Mag. Oct. 442 At this time the upper portion only of the Menevian (then called Lower Lingula Flags) had yielded any fossils.

1934 Philos. Trans. (Royal Soc.) B. 223 396 Agn. integer is recognized from the Menevian (Porth-y-rhaw), South Wales.

1987 Jrnl. Geol. Soc. India 30 187 The Tonkinella beds of Kashmir can, therefore, be correlated to the Oryctocephalus zone of Spiti and it marks the beginning of Menevian.
