  1. What Is This?

    Good morning all, we have recently found this in a local river and are very curious as to what it could be.. we initially thought that it was petrifies wood or a cross section of a pine cone.. but we are newbies and don't really have a clue.. we have had a really good look online and still have no clue. if anyone has any suggestions we would love to know your thoughts.. its approximately 2 inchs x 1 inch.. I have taken a pic from both sides. so you can see the resin/sap/amber running all the way through.. any knews is good knews.. please help..

  6. Petrified Wood Question?

    Hello, I have some beautiful specimens of petrified wood, and I would like to know if there is a way I could bring out their natural beauty (like how they look when wet) without damaging or significantly altering the piece? Any type of coating? I don't want to polish them (don't really have a way to polish anyway). I mainly want to bring out the colors of one piece in particular, because the wood grains are still visible. I can post pictures if you want to see it.
  7. I found this very unique and colorful petrified wood in the high Sierra, very different in color than any other I have seen around the region. So far I have not been able to ID the species since the material is extremely agatized/opalized. Has anyone found anything similar in Califoria or Nevada? Is this as rare as I think it is? Any idea what species? I polished a piece (pictured) and the rest are as found. Thanks for your help.
  8. Wyoming Mystery Rock

    A couple of my friends went on a rockhounding/fossil hunting trip throughout Wyoming and Utah in June of this year. They made so many stops and picked up so many rocks that something was bound to get lost in the shuffle. What got lost was the ID of this rock. The outside of the rock looks almost like a chunk of old, pitted cement, but when I slabbed it, I found a beautiful interior. The slab in the photo is approx. 10cm x 11cm with a swirled pattern of solid pinkish stone and more translucent quartz/chalcedony. The slab is 7mm thick and has several holes all the way through it. It doesn't look like photos I've seen of palm wood and it doesn't look like the petrified wood I am familiar with from Arizona and Wyoming. Any ideas?
  9. 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.
  10. 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.
  11. 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???
  12. 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.
  13. 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

  16. 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...
  17. 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!!!
  18. 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!!!

  21. 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?
  22. 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.
  23. 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
  24. 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
