Article Grading: I live in south central Texas, a place that used to be the bottom of a shallow sea. There are many different kinds of petrified wood on this property. Many I believe to be several hard wood types, although I do not have the equipment to classify the different types. Many I know are petrified palm wood. There are many kinds of different palm woods on this property, some of which are the state stone of Texas. I have found some sort of petrified vine, and after cutting it I still do not know for sure what it is. The person that runs a rock shop has said it was some sort of vine. It is coal black with some red spots in the cut end. It is a beautriful peace. I have also found a lot of marine fossils and I can not find anyplace on the web to identify them. They are not in several books on Texas fossils. i have several grasses in what appears to be flint rock and what appears to be some sort of tube worm in flint also. I have found several of these. If any one from Texas reads this I would like to hear from you via email.tooter 04:33, 6 March 2007 (UTC) |

[edit] Images
I have this image, which offers a lot more detail. Adding or replacing? --Dschwen 01:56, 18 Nov 2004 (UTC)
- I just added it at 300px just to see what it looked like with the earlier pic. What do you think? I'd say add it. Play with size maybe. -Vsmith 02:43, 18 Nov 2004 (UTC)
- With two pics in the article I think I prefer the Wikipedia default thumbnail size. The fullsize pictures on the other hand should be as big as possible (in agreement with http://en.wikipedia.org/wiki/Wikipedia:Image_use_policy --Dschwen 02:54, 18 Nov 2004 (UTC)
- Works for me. That is a great photo at full scale. The article could use a bit more info ... maybe some day. -Vsmith 03:16, 18 Nov 2004 (UTC)
[edit] Additional information
How long does it take petrified wood to form?
- I would really like to know that also. I think this article needs a little more info. It's why I searched the article out. --Shinto 07:03, 11 March 2006 (UTC)
How do these trees form, if they are going through layers that span 100 000 years? :X --Ningyou 03:52, 30 June 2006 (UTC)
Yes, more specific information relating to the age of such fossils is needed here. Such wood fossils are paleontologically "recent", because hardwood plants/trees came into being after the Cretaceous period of geologic time came to an end some 65 million years ago - along with the dinosaurs - because of a cometary collision with Earth. -- Khorasani 14:26, 15 December 2006 (UTC)
I just come back from a trip to Indonesia, where they had vast quantities of petrified wood for sale. The origin of this is Kalimantan (Borneo, Sulawesi, Sumatra and Java. The coloers vary from black to white with a lot of yellowish, orange teints inbetween. I am not a scholar on this subject so I happily leave it to other, more subject educated, people to update the main page. I'll try and leave a picture of quite a large trunk (about 2,000 KGS).

[edit] Merge?
The articles of Fossil wood and Petrified wood are on the same subject. Is there a reason why we should have two articles on this, especially when neither is large enough at the moment to warrant a content fork? Aditya(talk • contribs) 05:39, 25 January 2008 (UTC)
- Are these articles about completely the same thing? In Fossil wood, it says, "Fossil wood may or may not be petrified"; if that is correct, we would still need a separate article on fossil woods that are not petrified. In Petrified wood, it says, "Petrified wood is a type of fossil", indicating membership, but not equivalence. - Neparis (talk) 20:23, 25 January 2008 (UTC)
- At the same time the article on fossils say — "Fossils (from Latin fossus, literally "having been dug up") are the mineralized or otherwise preserved remains or traces (such as footprints) of animals, plants, and other organisms" — and the article on petrification says — "In geology, petrifaction or petrification is the process by which organic material is converted into stone or a similar substance." The other types of fossils apparently are fossil records of animals, microbes, paw prints and such stuff. The "may or may not be petrified" part seems to a description of extreme conditions, may be good for a section at the bottom of page. Aditya(talk • contribs) 01:34, 26 January 2008 (UTC)
