replies: text: *However, recent studies question the validity of most Precambrian fossils in chert and suggest that some of those fossils may be contaminants, fluid inclusions, or carbon threads formed abiologically.
With references it can be reinserted without the recent studies and some... Vsmith 03:14, 24 May 2005 (UTC)

message: The Terminology section (bravely) tackles the various meanings of "chert", "flint", etc. It needs to be more clinical and categorical. Also it needs to include definitions from standard dictionaries, and not rely solely on specialist sources. The two references provided are from specialist archeology journals.
I came to find out the difference between chert and flint, and I still don't know.
I came to Wiki after looking at this article , assuming that Wiki would be more concise, but I found the opposite, and also that the two appeared to contradict.
What's needed is very clear distinctions between general usage, and each of the specialist usages. ("Archeologists call it blah-blah, geologists call it blah-blah, builders call it blah-blah, gunsmiths call it blah-blah, etc.) And the whole reason I got here was the word's use in the "Gold Diggers" TV show. I assume the definition was a geologist's, but I still don't know. Leptus Froggi (talk) 22:11, 1 December 2012 (UTC)
thread_title:  Terminology needs clarification 

message: The article mentions novaculite but fails to list it in the "Varieties" section, and makes no mention of its important use for whetstones.  I'd like to see that remedied by somebody who knows the subject better than I.  J. D. Crutchfield | Talk 21:31, 18 September 2014 (UTC)
thread_title:  Use of novaculite as whetstones 

message: I'm not a huge fan of the globalize template, but in this case I've added the Globalize/US tag, because all the occurrences and all but one of the images are from the US and the terminology section is mainly from a US perspective. Anyone visiting this page at the moment would be surprised to learn that this rock type has a truly world-wide occurrence. I'm a bit busy on some other articles at the moment, but I will do something here eventually if no-one beats me to it. Mikenorton (talk) 13:08, 20 February 2016 (UTC)
replies: text: As this a science topic, I fail to see how the template applies. Rocks are rocks and chert is chert. Also, as WP is English language based, the references are going to come from English language sources. Removing template.  – S. Rich (talk) 21:47, 11 June 2017 (UTC)
