Include in your post information that you think would be useful for this article. You can simply ask questions or ask for clarification, and maybe an editor will post. --KP Botany (talk) 06:23, 23 January 2009 (UTC)


This image: Does anyone know if that is a natural formation completely, or if the coloring was put on by humans? It looks like the edges have been highlighted in black. I have no idea either way; but if anyone knows for certain that its a fully natural formation, I think that should be explained in the caption. (talk) 13:56, 9 May 2011 (UTC)

It is all natural coloring. Wilson44691 (talk) 19:12, 9 May 2011 (UTC)

Talkeetna Mountains Hadrosaur Paragraph[edit]

The paragraph about the Talkeetna Mountains Hadrosaur is far too specific to this one fossil dinosaur and discusses virtually nothing about the taphonomic aspects of concretions to be appropriate to the Wikipedia article on concretions. Furthermore, this paragraph only rehashes duplicate material found in the Matanuska Formation article. Therefore, I removed it. If such a section is to be added to the article about concretions, it needs to discuss the taphonomic aspects of concretions relative to vertebrate, invertebrate, and plant fossils in general instead aimlessly babbling on about a single fossil dinosaur fossil as the paragraph, which I removed, does.Paul H.

Medical Concretions?[edit]

My doctor says I have a concretion in the back of my throat. It looks white and he says its from accumulated food and is related to my tonsils swelling due to mono. Shouldn't there be an article about this other concretion as well? (talk) 21:34, 11 August 2013 (UTC)
