liassic

The only form that obviously comes up on BGC is the capitalised Liassic with the given meaning; if this can even be cited as a lowercase word, does it really refer to lias in general or to just the Lias, as Liassic does? —Μετάknowledge^{discuss/deeds} 02:45, 22 May 2015 (UTC)

I added this one, which means I read it somewhere – probably, judging by the date, it was Richard Fortey's The Earth: An Intimate History. It's also in the OED though, so I'm pretty certain it exists. They have the following cites:

1833 C. Lyell Princ. Geol. III. 378 Metamorphic rocks of the Eocene or Liassic eras.

1854 A. Adams et al. Man. Nat. Hist. 561 In the Liasic period of the secondary formations.

1854 H. Miller My Schools & Schoolmasters ii. 37 The first ammonite I ever saw was a specimen..from one of the liasic deposits of England.

1854 H. Miller My Schools & Schoolmasters xxi. 451 Both shale and nodules bore, instead of the deep liasic gray, an olivaceous tint.

@Widsith The OED doesn't trouble itself with attestation the same way we do. They want to illustrate use, but we want to prove it (hence their acceptance of terms that don't pass our CFI). Not one of those cites serves to save this entry, but instead are support for Liassic, Liasic, and liasic respectively. —Μετάknowledge^{discuss/deeds} 05:50, 22 May 2015 (UTC)

Well, whatever. Move to Liassic then. Ƿidsiþ 07:28, 22 May 2015 (UTC)

I changed the entry to an alternative-form-of Liassic, and added a couple of cites. Ƿidsiþ 07:38, 22 May 2015 (UTC)

(Edit conflict) Some citations that appear to be an alternative case form of Liassic:

• [...] jurassic or liassic strata have been conformably folded around this point, the whole having been since altered and denuded.
• The Wall, therefore, passes over rocks of the liassic era for some distance westward of Carlisle; but these rocks are there concealed by the thick deposit of drift.
• It cannot tell, for example, why trilobites should have flourished so profusely during the silurian epoch, and have died out before the deposition of the oolite ; why chambered cephalopods should have culminated, as it were, during the Liassic era, reptilian life during the oolite and chalk, or why mammalisan development have been reserved to the tertiary and current epochs.

and some that appear to cite a general "pertaining to lias" sense.

• A totally different liassic stone is Blue Lias, a whitish-grey stone obtainable only in relatively small pieces and difficult to dress.
• STOKE-SUB-HAMDON (Sm), called Stoke-under-Ham locally, is on the Yeovil-Ilminster road right under Ham Hill, from which it quarried the beautiful Liassic stone for its charming cottages.
• The top of a liassic stone wall/foundation, probed to a depth of 1.5 m, was recorded from 50 cm deep. A secondary footing of 5-6-cm handmade bricks, bedded on a course of liassic stone, overlay from a depth of 20 cm the above foundation.
• The concrete jointing or matrix is probably a mixture of local Liassic lime and river or glacial gravel.

Of course, these are mostly from Victorian-era journals before palaeontology came into its own, which means that differentiating the two senses isn't always easy (just as it's hard to tell whether cretaceous is being used to mean "roughly 100 million old" or "pertaining to chalk" in many of these journals).

RFV-passed based on Smurray's excellent citations, two of which I've typed up and added to the entry, where they join two already present. - -sche (discuss) 21:19, 6 February 2016 (UTC)
