A couple of visits to the bottom of the mighty Rio Grande is south Texas after a good long visit in upstream the Rio Grande mountain Texas taught me how complicated and large scale all that business is.I found Flower Garden Agate in veins above 3-4000 feet where it is formed in veins/pockets on the Woodward Ranch.And then found rounded pebbles of it way down in south Texas.A good many of the agates formed around That Alpine area have washed down to south Texas.As those from the hills of Mexico and other agate deposits from Texas,New Mexico and who knows how much further north.Those agates are specific types and carry a signature with them.The best library of such is the flicker albums of dardilrocks.Look at the pebble agates he has sawed and photographed.That is a fine example of washed or pushed material and it's condition after it's travels to the south of Texas just before the Rio enters the ocean.Cool stuff man. Sounds like a platform for debate too.But the where and the when is way to interesting.And people have walked and hunted rocks in areas and probably know more than geologists about a lot of what came from where. I like your interest in a great subject.

I've found wood logs in gravel pits that have so much external detail remaining that I wonder whether they were transported down here by great floods and then petrified down here in South Texas, buried under mud and silt. The time and conditions required for this transformation is something I have to spend a little time understanding. The amount of pet wood in some areas around here makes it hard to imagine that it all came from up country.

n8hounder, My PM to you was to explain how to post multiple photos in a single message - I in no way intended to discourage posting photos - in fact by making the photobucket shift you will be facilitated in posting photos. Sorry if my message was not clear. Here in New Mexico we find petrified wood almost anywhere we go along the Rio Puerco (in riverine deposits) and much of it showing a considerable natural tumbling. It has moved far and over much time. Cheers and keep the queries coming. Tom

Yeah Tom sorry about all my confusion that was "my bad" . I didn't understand the motive for someone to send that who I thought I had never met and I had completely forgot that it was you I had spoke with a little bit about that before getting your pm ....Damn my memory.. had lots on my mind and being new here I was a little on edge. The last form site I tried , a English geologists site was badly designed and I had some dude right off started being impatient then down right rude with me. Anyway thanks so much for all your help and patience with me This site and the people I've met here are really great. I'm new at using forms ,but I'm feeling more comfortable here now. I hope I don't seem like to much of a spaz... And any advice or suggestions you might have for me would be very cool and appreciated. I also think its interesting your a retired zoologist. Mind if I ask you what was involved with that job and where you were working? Any science is very interesting to me. I always wanted to be in a scientific field of some type. I read Discover magazine, popular science , Smithsonian, popular mechanics and also used to get Nature..so I'm a fan. Your the first zoologist I've ever encountered.

And James very cool I will check that out. I've never been to that part of Texas sounds like a good trip. I got to say that even though I might never put the whole puzzle all together myself and wouldn't ever assume I really had till I get some experts to all tell me the same thing. I can't just decide it's to complicated to bother with thinking about it. I love to think of the big impossible questions... I got round to having a look at dardilrocks very cool indeed thanks for telling me about that...also thanks for the complement, I'm glad I got to meet you your a neat individual and liked by all I have read posts form. Oh and I read some one make reference to you making blades? Is that knife blades? stone or metal? I do a bit of that , I would be interested to see what you have ... let me know ..see ya around..

Carlos made a good point about petrified wood in south Texas.It's everywhere in Texas.Makes you wonder what was where.Good ole boring Florida,my coral reefs are sitting just about where they formed.Fracture free and waiting for you guys to collect them.

I find lots of petwood here in Oregon,most of our stuff is washed down river from the Central areas of the states from the days of prehitoric pasts! All of my petwood goes in a clear gallon jug with water in it,to show the colors and such....Don't think I'll ever get it tumbled....

Also with trying to really find where and how petwood is found,can't really be answered.Fossils have a zone and time place with them,to find their fossilized parts and etc...but petwood can come from far back as when the world started to four hundred years ago,depending on what was created to form the petwood! I have found petwood in North Dakota that I didn't think deserved a place on my shelf,but to be put in my bone rock pile outside because it looked to be brittle and no colors to be seen on the wood.(not true in some aspects) But here in Oregon,its everywhere and colors galore! Odd,but worth the study if you choose to do so.....Great subject,I like it!

Petrified wood is a fossil/mineral that could create obsession.Variety,color,a fossil,wish it was in Georgia like it is around you Fossilman.Or like it occurs in Texas.Thought i found a chunk while snorkling in Juniper Spring's Florida w/my cave diving cousin.He found a chunk too.Like 6 inches in diameter and 2 feet long.Years later his diving partner saw his and said"where did you get the mastadon tusk?".Me Ed were trippin.He fossil dived for years and never found pet wood.Cause it's not hardly there.We had found museum pieces and never knew it for 30 years.

I have read that there is some petrified wood in Washington state that's carbon dated to 15 million years it's preserved in such a way that it's still readily combustible... It has the distinction of being the oldest to be able to still carbon date..
