  1. Petrified Wood

    I was in Thailand (Korat/ Nakhon Ratchasima) and i found petrified wood. I do not know what this wood is. Can you help identity? How old it is? Size 7,8"x3,9"x1,95" and weight 6,63. Size 20cm*10cm*5cm and weight 3kg.
  2. finally got out recently and hit a hotspot in the Triassic of S.E. Pennsylvania, the Newark Supergroup. scored these two pet wood pieces with nice grain, each about 10 inches length (scale bar is 4 inches). plus several more smaller pieces.
  3. This was found in an area where a fair amount of petrified wood has been found. After admiring and examining its awesome detail for hours, I accidentally discovered that it rattles when shaken! It doesn't seem to only be dirt/gravel inside, as the sound and feel of the shake is deeper & larger. No holes or cracks visible. I'm dying to know what this is..and what's inside. It was found in southeastern Ohio. Any ideas what this is???
  4. Ct's Petrified Forest

    Anyone hear of CT's petrified forest in Southbury? I might go for a hike to see if I could find any fossils in the woods near the sites they have been found. Most of the petrified trees there are a new species of conifer and work is still being done on another possible species. It being the only Mesozoic forest in New England (yet) makes me wonder where the creature fossils are as most trees are persevered by flash flooding/mudslides.
  5. From the album Double Duty

    Modern dampwood termites are know to line their nests with fecal pellets. Well, evidently they have been doing this for millions of years. In this microscopic view, the tiny white termite eggs can be seen among the larger pinkish coprolites. They are shown in relation to the tip of a pin. Period: Paleogene - Paleocene Epoch Location: Nowopskow (Lugansk Gebiet), Ukraine

  8. Wood Cell Structure

    Hello Forum, This week I've been having fun trying to get better at making photographs through the microscope. I currently use a compact camera (Panasonic DMC-TZ25) on a tripod. The following previous threads were quite helpful and I am looking for more tips, tricks and techniques. For example, does anyone here have good ideas on how to photograph specimens with very little contrast/color through the microscope? Thanks, Tim All: Araucarioxylon* wood from the Triassic of the Chinle Fm., Arizona, United States. Cross-sections showing typical honeycomb-shaped tracheids. Left: Osmundacaulis leaf trace from the Jurassic of Tasmania, Australia. Just perfect as a copyright-symbol. Middle: Quercus wood from the Miocene of northeastern Hungary, showing the diagnostic wide rays and ring-porosity. Right: Quercus? (live oak?) wood from the Miocene of central California, showing the onset of a medullary ray. * Well, perhaps Araucarioxylon is not the best name to use any more, given this paper. But then, you know what I mean...
  9. Costa Rica Trip Nov. 2014

    Just returned from the wonderful country of Costa Rica. The trip was to celebrate my grandmothers 80th birthday! Being this was a family trip, I had limited time for any "back country" explorations, missing too many suppers would not have gone over well!! So I decided I would take day trips to as many beaches as possible, and consider all info collected for a future trip if anything really caught my eye. We were staying in a villa in Manuel Antone. I walked the local beaches all the way up to Quepos and paid special attention to low tide coral that would trap anything washed up. The current runs north there, so I focused on areas where the land hooked outward to catch the most debris. Beautiful sea shells, mullusks with opalesque interiors and coral were aplenty, but that is not what I was after. After 2 days and a good burn all I found fossil wise was what looks to me like horned coral encapsuled in a light green limestone. I also came across some small chunks of agate that I will have to cut n polish at a later date. I felt I had exhausted my search, and had little reason to believe these finds were deposited by any nearby rivers. So I took a bus ride south down to a little surfing village called Dominical. The beach was all tumbled river rock and driftwood. I had lost my boots on a prior drunken evening and was stuck wearing my girlfriends pink walmart beach shoes... Brutal on the feet!!! I rented a surfboard as the waves were pretty nice, and there was plenty of room in the line up to partake. My cash was in a ziplock bag which I brought out surfing, but due to thieves, I had to bury my cigs and lighter under some rocks, and used some driftwood as directionals to find in the future. While squirreling away my possessions I dropped a piece of burnt driftwood on my rock pile to help cover my stash when I noticed something... The sound was all wrong!! There was no thud, but a high pitched clack!!!! Sure enough, I had myself a piece of petrified wood!! I surfed to my hearts content, and decided to do some investigating. There was more pet wood, not in abundance, but enough to think the source was nearby! When it began to rain I noticed jasper nodules too. I showed the wood to a vendor who was working on a wire wrap necklace. He said its from the river to the south!! This led to 2 fundamental problems, 1- lack of time, 2- a good potential for crocodiles! I had seen my fill of crocs there already, some locals would feed them chickens for tips from tourists... They are quick!!!! They are mean!!! And I'm in their house!! I decided I will have to return in the future for a surfing/digging trip. I have a local guide set up for the river, he wants the wood for jewlery. I promised to teach him how to set up cheap lap saw/ polishing units so he didn't have to pay someone else for cutting his jewlery. Airfare is cheap after the new year. I'll pick up on this thread later!!!
  10. I Purchased Some Mystery Petrified Wood Today

    Here goes 4 images of pet wood that was saved from a demolished gas stations wall along the nj shore about 10 yrs ago. I am actively trying to contact the local historical society for any leads that they may have. In the meantime, I am curious about what ideas others have. Circle cliffs Utah was a guess from a buddy of mine. Lots of Druze and small crystals on these specimen. I'd love to hear any thoughts and can get close ups if needed. Thanks!!!
  11. Petrified Wood?

    Is this petrified ? Could it be coral?

  13. I have some of my fossils in my basement. I noticed that some of the Mazon Creek petrified wood had started to sprout hairy growth of some kind. I'm wondering if this some odd mineralization happening to the high sulfur coal fossils or if these are spores of something that are sprouting because of the dampness in my basement. Here's some detail. If they are chemically reacting, should I coat them with something to prevent the reaction?
  14. The following pictures are some shots of my petrified wood from Madagascar. Let me know in your opinion, what is the species of the tree this wood belongs to.
  15. Dear all, Since it is simply impossible for an individual collector to collect everywhere, trading offers a great method to diversify. Several TFF Members are actively collecting plant fossils and together we cover an almost worldwide range of different localities. Even if you are specializing in a particular area, fossils of equivalent age from elsewhere could prove interesting material for comparison purposes (for example, there are some interesting parallels and differences between the European and North American Pennsylvanian floras). My question is, therefore: is anyone interested in trading plant fossil material? Anyone who had any plant material to offer for trade, or is looking for particular specimens to trade, please chime in! Cheers, Tim
  16. Well im heading down to Mazon creek in a few weeks. Forum members Digit (Ken) and Rob Russell should be meeting me down there. I think we're going to dig the Park, but it's still up in the air. Feel free to join us on our hunt, it would be nice to finally meet some members! Things to bring. -bug spray and/or tick spray -shovel, gardening claw, rock hammer or pick-axe -water, snacks, etc. -bucket/s (big or small) -backpack to help carry everything -gloves -cake it will be Ken's Birthday!!! ^^^^Feel free to add to the list^^^^ Again it's June 7 th 2014. 9 a.m. exit 236 on I55 Coal City exit @ the Shell station on Johnson rd Rte.113. Hope to see you out there! Weather update if you're interested http://m.accuweather.com/en/us/chicago-il/60608/weekend-weather/348308
  17. Petrified Wood;

    I found this in Lockyer waters on Dry acreage is it petrified wood? Please help me identify:)
  18. Fossil Palm Tree?

    Here is a interesting specimen of pet wood, found by myself in Dec of 2013. It's from the late Cretaceous, and i assume it is Palm wood. I've found other palm specimens, but not quite like this one. As,all other examples never had holes this large, about half the diameter of these holes or a fraction smaller than that. Is it Palm wood?
  19. Bandera Texas!

    So I am having an AWESOME trip in Bandera Texas. I found the first petrified wood I've ever heard of being found here, I went to a public park and uncovered a sauropod trackway that is flanked on one side by a theropod track. I found I cave that is made of coral with gastropods and clams in the coral, and a very large gastropod beside the river. I have even managed to rescue a couple stranded longnose gar! I am going to keep updating this topic over the next couple days, and I am going to attempt to make casts of the dinosaur tracks!
  20. This is a specimen of a type of "wood" that has been replaced by iron bearing waters, it is presumed. This looks alot like stigmaria, but it absolutely came from a late Cretaceous formation. If stigmaria, perhaps it was anciently reworked into the Cretaceous sediments? This unidentified specimen is astonishingly preserved! It almost looks as though it will start moving in your hand!!! The whole internal parts can be visually made out....even structures that appear to be veins! Strange....all i can figure is this specimen must be the product of a very violent environment, perhaps a hurricane of something...because it was torn from what it was attached to,in the process, one side of its "bark" was torn away also....revealing it's complex internal composition. Then, it seems, before decomposition could even begin...... !!!!! ...... it was deposited in the sediments that became its home. If that doesn't explain the remarkable preservation, then i am baffled as to what happened. Still, this paleobotanic needs a name. Any ideas?
  21. Finds Around Salton Sea

    We found a couple of interesting pieces west of Salton Sea and east of Anza Borrego does anyone know from what era these can be from and what they might be? Thanks for the information We believe this is Petrified Wood Specimen 1 Specimen 2 Specimen 3, looks like a petrified plant of sort, not sure what. We think a cactus, because of the holes Specimen 4 we think might be coral but have no idea what type, all of these pieces were found around each other Thanks for the information.
  22. Permian Petrified Wood

    Hi All, I have been collecting a bit of petrified wood of late and wanted to put a name to the Permian plant from which it came. The photo below is the most common type of wood that I have found, however I have found various kinds that I would be happy to post should anyone be interested at having a go at ID-ing.. This sample is from the upper Permian formations of the Sydney Basin Australia, manly comprised of siltstone, mud stones and sandstones deposited (in this particular area) from a fluvial deltaic setting. As there is various coal layers throughout the formations, from cool climate peat deposits I would say that it would be something along the lines of Glossopteris or some kind of seed fern? (I have found Glossopteris leaf fossils in near by formations). If anyone is good at ID-ing wood, suggestions would be much appreciated
  23. Recently I had a pretty decent day hunting the scarce petrified wood in the Triassic (Newark supergroup) of southeastern Pennsylvania. The largest piece in the photo weighs 13.5 lbs (6.1 kilos). It was the first specimen found in the first 5 minutes of the hunt, so I was hoping a good day would follow. And more nice wood did follow that first one. As usual, most pieces have a brownish hue, and the silica sparkles a bit. No agatized wood. Scale bar at photo bottom is 4 inches (10.16 cm).
  24. Hi I recently got this Thai Petrified Wood which the previous owner said to be about 3 Million years old from the Khorat Plateau of Thailand. Although I am under the impression that for a fossil to get this kind of agatization a specimen need to be much older. Here is the specimen: The colors and type of agatization I see on this specimen looks to be very close to the kind you see on petrified wood from Arizona or Madagascar which I believe are Jurassic specimens? So perhaps the one I have may be much older than the info I was given? Thx
