Cell background colors

The background colors of the cells are a means to communicate the relevant organism's taxonomic status.

Color key Taxon Reclassified taxon Taxon falsely reported as present Dubious taxon or junior synonym Ichnotaxon Ootaxon Morphotaxon		Notes Uncertain or tentative taxa are in small text; crossed out taxa are discredited.

Red for reclassified and preoccupied

I thought Navajo sandstone was deserving of its own entry in Wikipedia, since it is one of the most impressive formations found in the Colorado plateau and is one of the primary reasons that Utah has so many national parks. (from User:GroupX}

Alternate names for Moqui Marbles

In the section: Iron Oxide Concretions (Moqui Marbles), I've added the additional names used by enthusiasts, and documented the rock/geology enthusiast's side whree the names were references. This is common usage, so hopefully the reference is sufficiently valid for laymen's terms, just as examples of names used: Moqui Marbles, Moqui Balls, Moki Marbles, Shaman Stones, Thunderballs. They all describe the same physical thing. Just different names people have used over the years.

See also

Have added concretions, Martian spherules and Stone spheres of Costa Rica to the list of "See Also." I think these are relevant wikipedia-internal references for folks interested in perfectly spherical concretions. I know that similar structures have been found in the SW, Mexico, Costa Rica, Africa, and suspect that similar features remaind to de discovered elsewhere. Cause unknown. Nonetheless interesting to see the parallels. I'd almost suggest that Moqui marbles should have its own page to discuss them in more detail, and to separate them from the sandstone article. Sinec the stone spheres of Costa Rica and Martian spherules have gotten their own Wikipedia pages. But, perhaps it's not necessary, since Moqui Marbles has its own section and can be linked to directly, using the # (target) info.

Stone Spheres of Costa Rica

It should be noted that the artificial nature of the Stone spheres of Costa Rica is well known and as documented in their Wikipedia page, the publications mentioned in its text, and the web pages in its external links section. They are now known beyond a shadow of any doubt to be man-made artifacts. It is an established fact that they are not any type of concretion. They are completely unrelated in origin to (1.) any concretions, i,e, either Martian spherules, Moeraki Boulders, or Moqui Balls; (2.) megaspherulites, i.e. the stone balls of Cerro Piedras Bola of Jalisco, Mexico; and (3.) any other spherical and semi-spherical object of natural origin. The stone spheres of Costa Rica are only related to man-made stone balls such as lapidary spheres, stone round shot (cannonballs), and the Carved Stone Balls of Scotland and have nothing to do with spherical and semi-spherical objects of natural origin. Thus, as far as the the Stone spheres of Costa Rica are concerned, they lack any relevance to a discussion of Moqui marbles.

Map

I think a map showing where the Navajo Sandstone formation occurs would be informative. Thoughts?

Sadly I don't have the time; but hopefully someone else does! —Preceding unsigned comment added by Quickos (talk • contribs) 01:35, 20 October 2010 (UTC)

Backwards take on redox

Just checking solubilities and Uranium Dioxide (+4) is insoluble but oxidized Uranyl (+6) salts are soluble. The opposite of your text. Wikipedia articles verify Uranium solubility. You ref Navahoe sandstone, so you should know that "Four Corners" coal (a reducing environment) is associated with Uranium deposits in that area. Uranium captured by coal is the cause of radioactivity released by coal burning powerplants. Shjacks45 (talk) 22:35, 26 March 2020 (UTC)
