  1. Would anyone have any sort of idea of how much this Stigmaria fossil might be worth? It is approximately 12 in. x 6 in., I do not know where it originally is from. It was found within the landscape rocks of my sisters house, which is in southwest Ohio. From what I know of these, they are Carboniferous and not typically found around here, since most of the fossils found here (Cincinnati, OH) are usually Ordovician. I was thinking this stigmaria might have been transported with rocks from a quarry for landscaping purposes. The house is over 50 years old, so I have no way of knowing where the rocks came from. I was thinking of offering my brother in law something for this fossilized tree root (He does not collect fossils by the way.) What would this stigmaria be worth to someone who collects fossils like me? Thanks to anyone who replies, your opinions will be appreciated.

  3. Found on a beach outside of Windsor, Nova Scotia, Canada - closer to Cheverie. Beautiful slate beaches and near huge gypsum deposits. March 2016
  4. Can anyone tell me the name of the tree ? Diameter: 3 cm
  5. this is given to me via an inheritance so I don't know where it came from it looks like it has dark red blood cells almost in it can't decide if it's bone or tree. any ideas? thank you in advance for your time.
  6. Hello. On my stretch of the Northumberland coast in England I have found evidence of petrified trees, such as this stump. I can find no information about them online in my location, so please could you tell me (based on this stump) when would it have been a living tree and probably what type of tree? At various points along the coast the remains are usually within grey mudrock or grainy sandstone, but this stump is in hard solid rock (I don't know of what type; maybe of silt as it's not visibly grainy). What would the environment have been like here when this tree was alive? Anything extra you can tell me specifically about this tree/stump in the context of my location would be gratefully received; I need as much info as possible, so any further sources of location specific help you could point me towards would be fantastic. Thank you very much.
  7. UPDATE: August 20, 2013 - A new site for Wattieza - the world's oldest known tree Since posting this, the debate about "orthocone" versus "Devonian tree" has been settled. The Devonian tree experts have weighed in and confirm that these are Devonian tree shoots. They were growing in a swampy shallow marine environment similar to how modern mangroves grow. Since our original discovery - which represents an entirely and previously unknown site for Devonian Wattieza trees - my wife and I have collected more than a dozen separate fossils including some with surrounding substrate, from this site. I have cleaned most of the specimens and am taking closeup photos from all perspectives, now, to show such things as the central tube (called a stele) that runs through the core and the texture of the outer covering. In addition to Wattieza we have also discovered a separate Devonian plant species which we are attempting to evaluate and identify. Here is a photo from our SECOND site visit that shows the actual small Wattieza stump fossil that we collected, placed in front of a photo of the same fossil in the substrate as we found it. You can also see the adjacent "stick" which we currently believe is NOT part of the Wattieza stump - a separate closeup of the stick is included. We are currently looking at our several "stick" fossils and planning to cut one to look at the cross-section pattern, to try to determine the plant species. We feel that these finds have the potential to add new information about Devonian trees and plants, from this new site. It is also significant that we found these in a Devonian site where there are normally only marine fossils so we appear to have found a rare "island" of ideal conditions where young mangal Wattieza trees were growing in a paleosol where the conditions allowed fossilization. Geologically, these fossils are at the lower end of the "Tully limestone" formation. Our Devonian tree/plant finds confirm our thinking as "advanced amateur" paleontologists that as amateur fossil hunters we all can and should be using our time and knowledge to discover new sites and add to the fossil record. The small "army" of fossil hunters represented on The Fossil Forum have a unique opportunity to look in places where scientists may not have an opportunity - or inclination - to search. Once in awhile we discover something important, which seems to be the case here. OUR ORIGINAL POST Before I write our 4th of July trip report, I asked for some ID help with 3 tube shaped fossils we discovered at Tully, NY (Devonian, Hamilton Group) - the first opinion I received is that these are orthocone cephalopods. A contrary view is that these are Devonian trees! I modified the description slightly from the original post to reflect the current debate which has made this a "hot" topic. Have to admit, it's kind of cool that our first major fossil trip this year has sparked such an interesting discussion! Nan and I found these in situ sitting vertically in the substrate of a new construction site. I had found a few very large (2 inch diameter) cylinder shaped segments in the rubble that looked like cephalopod pieces and they were the largest we have seen to-date, so we were intrigued and started pulling away the substrate in the vertical walls exposed by the bulldozer. The first two fossils were found about a meter apart and the third was found about 300 meters away over a hill, but in the same level strata and depth. I'll do some minor cleaning, take better pix of the recovered fossils and segments, and add them soon - there appears to be a siphuncle structure running through the center, and other clues to the identity. Here is a quick view of how and where they were found - of course we realize it's very rare to find this type of fossil vertically embedded in the substrate. Nan found the first one, I found the next two and excavated all three - will provide more photos soon but hoped to get an ID first. The third sample had about 2/3 with the bottom portion missing. The first two appear to spread out slightly at the bottom. Several people suggested these could be trees and a few said other creatures but most people I talked to before posting this seem to agree they are orthocone cephalods. Aside from their size and shape (which is unusually large for the Tully shale so these are rare especially found in situ) - the primary convincing evidence is the siphon (siphuncle) protruding from the tip of the top of one of the specimens. This structure runs like a worm through the center - the other segments show holes in the center where the "wormlike body" ran through it. This argues against trees or other creatures but a few people claim that Devonian trees did have a similar center structure. The most confusing aspect is the lack of hard shell which should be present if this were a cephalopod - so what does that suggest? Another type of creature? Did they moult their shells and is this the "soft shelled" phase? Or is this a tree? Here is the top segment from the best specimen which clearly shows the siphuncle protruding at the center. In addition to the segmented tube shaped structures (they are all about the same diameter and length) there appear to be tentacle shaped structures on the left side although I didn't recover those when I extracted the tubes. Of course if this is a tree, then it is possible that those structures could be shoots. The tentacles or shoots were not recovered and are only shown in the photo which unfortunately limits the analysis. Here is how the debate seems to be shaping up: Pro Orthocone Cephalopod - These 3 specimens were found in what appears to be a Devonian marine environment where all of the fossils found there have been marine fossils. They have a small center "worm like" structure running through the center that looks like a siphuncle (siphon). They are all segmented and all the same approximate length and diameter. One was partially collapsed and distorted (some segments bulging outward). No one has suggested a cephalopod species that this might represent. Pro Devonian Tree - The horizontal strata where they were found contained very few if any marine fossils so they could be small young trees growing in the water. There is no trace of any shell fragments which is unusual if this is a cephalopod and the segments don't resemble cephalopod shells. There is a thin outer "skin" which could be consistent with ancient horsetail type bark. In the cross section of the segments, there are no concentric circles - in early trees there was pith, not traditional wood with concentric growth circles and some people have indicated that the first Devonian trees did have a similar center structure. The center core that looks like a siphuncle would be a core structure called a stele. Piranha suggests that this could be Wattieza sp., a prehistoric cladoxylopsid tree from the Middle Devonian that was discovered in Gilboa, New York which would be consistent with the location which was the Hamilton Group near Tully, NY. This genus has been called the earliest known trees. One of our goals for this fossil trip was to find something larger and distinctive/unusual and apparently we've done that. Another goal we've had since last year was to find a Devonian plant of some sort and it would be cool if that's what this turns out to be. I'll be just as happy if these are orthocones. The debate is hot on the ID for these and with all the attention and help from everyone, we should zone in soon. I'll take some more closeup photos this week and post them here. These are some of the largest fossils Nan and I have found so far and certainly the largest we have found in situ - it's fascinating that we found these exactly where they died and were preserved, 385 mya. I have to admit I felt like RomanK, who finds a lot of stunning in situ fossils and I have to admit, I was consciously trying to think like Roman and inspired by his example while searching for these fossils, which involved a lot of "excavation." UPDATE: NEW PHOTOS/CLOSEUPS At the end of this blog (page 3 and 4) I posted some new closeup images.
  8. tree, coral, rock?
  9. More than 40 years ago I met a California desert rat who was nearing the end of his life. He took me to his storage shed and showed me an amazing collection of fossils and minerals he had found over the years. He offered me fantastic fossils at incredible prices, but I was a poor student living on macaroni and cheese. The one thing I bought was a doorstop that he said was some sort of petrified palm. It doesn't look anything like the petrified palm we find here in Texas, but I wondered if anyone had an idea of what this is:
  10. Taken from my blog: http://redleafz.blogspot.ca/2013/04/birch-cove-west-beach.html One of the curatorial walks organized by the Fundy Geological Museum (FGM) took us to Birch Cove/Raven Head (Candidate Wilderness Area), North of Cape Chignecto Provincial Park. Here's a description posted by the FGM about the area: The province wants to designate the area as a Candidate Wilderness Area. But when we got to the site, we encountered something that could jeopardize the efforts to make it happen. I'll elaborate a little later. The other location that we visited after Birch Cove was West Beach, not too far West from the first location. Our first trek didn't take long and we had time a plenty before the tides came back, so we took the opportunity to head over West Beach. Here's the description posted by the FGM on their website for Apple River / West Beach: Both sites are part of the Carboniferous Cumberland Group (Late Carboniferous). This area doesn't show the same type of disturbance experienced further South near Cape Chignecto Provincial Park, which shows signs of faulting and folding. Birch Cove (1), West Beach (2) To get to Birch Cove is to drive West of Parrsboro (easiest way to get there) via Apple River Road or by driving South from Joggins on Shulie Road. Getting there is tricky if you don't have a guide that is already familiar with the area. The roads are dominated by dirt roads used by tractor trailers hauling wood. The roads are extremely bumpy and dusty, making the drive a bit of a drag. We parked the cars in a safe area and started down some semi-wooded trail. When I say semi-wooded, it means that the foliage is only a few feet in thickness on each side. The rest has been clear cut, and the landscape is just a poor sight to see. The province wants to make this area some kind of protected nature reserve, but there's not a whole lot remaining. Sorry sight indeed After a little pause to contemplate the area, we proceeded further down the trail where we got into a wooded area. Walking down the trail to the beach Raccoon tracks We made our way to the beach and it was nice, compared to the sight we saw up the trail just before. Water environments are the dominated feature when looking at the sediments that compose the cliffs in this area. The traces of past ice activity on a major scale is also apparent on the topography of Birch Cove. Sand stone cliffs mixed in with layers of conglomerate, marine sediments, topped by glacial till and raised beaches. Ken Adams (left), Kerr Canning (center), Matt Stimson (right) Warm enough for a swim =P Birch Cove is a nice site. Not a lot of fossils around but nice to see the diverse topography of the locality, which was a major factor in the region's local economy for many years. Several locals within the past two centuries had settled in the area and erected mills, using the water flowing down the Apple River. Kerr, which was part of the expedition, had found several artifacts from the previous century of settlers that had since abandoned the area a long time ago. He showed us remains of some of the settlement in the nearby forest. What remains are several sandstone blocks from various foundations. One of the old foundation After wandering in the forest for a little while, we came out the trails and hopped in our cars to head over to our second destination. West Beach is a few kilometers South-West of Birch Cove. The cliffs in this site have strata that are more familiar of the other sites such as Joggins. Also similar are some of the fossils that we found in this area, especially in the coal-bearing sections. Tree in situ The tree in the picture above shows the base of the tree with two of its 'surface' roots radiating out. Tree roots with root hairs Tetrapod footprint Overall it was a good trip. I had already been in the area before but further South at Spicer's Cove (which I suggest everybody go check!). The drive up and down the rolling hills by itself is worth the trip. One can spend the whole day in that area and come across a very diverse topography. Cheers!
  11. Hi to everybody, I just found this fossil-looking sandstone from Pliocene. It looks like a the internal structure of trunk, but I don't know if it could be some kind of bioturbation or any other think. Any guesses? Thanks!
  12. Alright. This post is wholly dedicated to two seperate trips solely on Joggins. My previous posts in this forum included short trips to the site, but this post is 100% Joggins. This was taken off of 2 seperate posts from my blog back in June and August 2011 - http://redleafz.blogspot.ca. Cheers! June Trek to the Joggins Fossil Cliffs (June 27th, 2011) - Part 1 Last week I went back to the cliffs at Joggins, Nova Scotia to sniff around and see if I could discovery different finds from my previous ventures. June had been a very wet month, so the chances for the cliffs to be revealing new specimens were high as I'm sure lots of sediment must have eroded. When I left early in the morning it was raining; a light drizzle with a cloud ceiling consisting of multiple different shades of gray, but that didn't damper my spirit as I had heard that the sky would open up sometime during the day. By the time I had reached my destination, the Sun had come out in full force. Reaching the cliffs I could see the rain had done its work. There were heaps of eroded cliff tailing on the ground and new rock falls, showing freshly cracked sandstone. There was a lot of debris and by the end of my walk, a lot of new things to see. The name escapes me, but I'll find out and edit the post. Oyster-type fossils with tiny snails. Same type of fossils, with my thumb for size reference. Close up of a clam/bivalve type fossil. More oyster-like fossils. I found trees that I didn't photograph before. The rain had cleaned the silt and mud, causing these trees to pop out right off the cliff face. Tree with root exposed. I've been coming here for almost 2 years and I had never found any fern-like fossils, until now. There was a new rockfall and some sandstone boulders had cracked open. I was lucky to find several specimens at one location. More ferns. Here's an example of a tree with roots extending out. The tree itself is barely noticeable, except for the outlines on the edges (lines going up and inside above my hat). The the roots (stigmaria) of this lycopsid type tree, on the other hand, are very detailed. You can see bits of other stigmaria sticking out of the rock on the edge (right side) of this photo. Close-up of the roots. Pic showing multiple trees grouped together (showing dense foliage) Fog building up Hardscrabble Point, which at one time saw its innards flying due to some crazy geologists and some sticks of dynamite. =P This last image shows what I came to Joggins that day to look for: trace fossils of Arthropleura. Arthropleura was an ancestor to the modern day centipede and could grow to almost 3 meters (~9 feet) and dominated the floor of Carboniferous coniferous forests. I was happy to have found these trackways. The fact that more than one trackway is showing on the sandstone slab and crossing one another is amazing, but also showing that the forest floor was hosting living organisms. On to Part 2!
  13. Continued from Part 1... June Trek to the Joggins Fossil Cliffs (August 31st, 2011) - Part 2 Hurricane Irene came to the Maritimes as a downgraded tropical storm. Strong winds and lots of rain were forcast but in the end it wasn't as dire as the weather forecasters thought it would be. Knowing that accompanying strong winds and rain, was the inevitable process of extreme erosion due to strong forces. With that in mind, I thought immediately of the cliffs at Joggins. I couldn't go the day after the storm had done its thing, but I had the Wednesday off, a couple of days after the storm had gone through. The tides would have been low extremely early in the morning, so I decided to leave Moncton at around 6 AM. As soon as I arrived to my destination, the Sun was just peaking out to greet me. My favorite spot in the Joggins area to search the cliffs is from Lower Cove Road. I take the path down the little bridge that crosses Little River and walk South towards the cliffs. From the bridge its about 100 meters more or less before you reach the first cliffs. Water receeding as the tide is getting close to its low point. The rain from Irene did a good number on the cliffs. The rain had battered the cliffs and the loose sediment had started to come down. When I walked near the cliffs, I could see huge piles of loose till and mud at their base. The cliffs had also started to show signs where water had run off and where blocks of sandstone of various size had slid down, leaving drag marks on the soft and wet sediment. Stigmaria (tree root fossil) with rootlets spreading vertically outward Cast of a tree with visible features Although some of those trees might have already been exposed, the rain helped make them prop out of the cliff. The tree specimen on the far right is a good sample that could be identified and studied for possible bone fragments within its core. [coin added for proportion, bottom left] [coin added for proportion, bottom left] [coin added for proportion, center] This tree like I mentionned before could yield tiny animal bones. When the conditions are right, small animals would seek refuge in hollowed out trees. Trees in the Carboniferous period weren't the same as the trees we know of today, but were more common to club mosses. Their center were more of a fleshy pit and these would create cavities that animals could use as shelter, as do small animals do today. Dawson thought that, when he first found small animal bones in these trees, that they had fallen to their death or such similar situation, but today the feeling is that it could have been a circumstance of immediate environment (ie. forest fire, suffocating, extreme undesirable environment toxic and deadly to the animal, etc). Calamites Bark possibly from Sigillaria tree The layer of coal can be seen here, showing its shinny underside due to the erosion mostly caused by rain. Littered on the beach were blocks of coal that had broken off from veins similar to this, due to lack of support from the loose sediment that held them in place. Tree section [coin added for proportion] Tree sections, foreground and centered on each side [coin added for proportion] This tree cast is possibly what had held most of the tree segments found littered close to that location. The features that suggest size had been weathered but still offer an idea of its girth (diameter). The roots extending from the bottom of this tree are nice as they offer features in situ that are identifiable. The coin was added for size proportion. [coin added for proportion] Calamites This was an interesting find. Laying on the beach I found what I first thought were chopped wood. At closer inspection, come to find out it was a section of a fossilized tree! The colors kinda threw me off from afar. Picking them up to check their weight, they were definitly heavy to lift. Cheers! - Keenan
  14. A Weekend Visit to A Road Cut Near Our Home Nan was busy this weekend so I drove to a road cut on Route 422 south of Pottstown, PA - about 5 miles from our house. I had been told by a friend at the Delaware Valley Paleo Society that there wouldn't be any fossils here - from the geological record, I think this is part of the Gettysburg-Newark Lowland Formation which is described online as late Triassic. The shale is red with some green and gray mixed in here and there. Telling me that there wouldn't be any fossils here was a challenge I couldn't resist. So I decided to see if I could find anything in this very barren but geologically interesting formation. What I found were fossils and impressions of a tree and twigs that resemble Siggilaria (which were extinct by the Triassic I believe), and a few other trace fossils and what I assume are some mineralizations that look like leaves but probably aren't. I wonder what kind of tree this bark pattern represents...any ideas? The roadside exposure is a very steep slope covered with golf ball sized rubble and lots of larger rock formations protruding, here and there. The roadcuts are located along Route 422 several miles south of Pottstown, Pennsylvania. I studied everything that was visible, cracking lots of rocks to see what might be hidden. Nothing, no marine fossils, not even a freshwater clam. I began to feel that this might have been a dry area, or mostly dry area. Then I came across a narrow cascade of rubble that had eroded off the steep wall and noticed some red shale pieces that looked like smooth bark of some kind. On closer inspection, I discovered several pieces (many were fragmented) that turned out to be a grooved bark pattern. In the first fossil (1.1, 1.2 and 1.3 with backview and closeup - see below) you can see: a) the bark pattern which resembles Siggilaria including one branch node (the round circle) and you can also see at the top where the bark ridges begin to branch into a diamond shaped pattern. Although this is supposed to be a Triassic formation, the tree bark has a Carboniferous look, but I'm not familiar with Triassic trees. Here are the images of the bark sample: BARK 1.1 BARK 1.2 BARK 1.1 Back View BARK 1.1 CLOSE Bark 2.1 and 3.1, and Fossil 4a(front) and 4b (back) - These are additional samples of what appear to be bark and branches/twigs: BARK 2.1 BARK 3.1 FOSSIL 4a Front FOSSIL 4b Back Twig 5 - Here is what appears to be a twig and twig impression: TWIG 5 Not sure what this is: FOSSIL 6 I assume these are mineralizations (dendrites) that look like leaf impressions but are chemical, not fossils - note the shale color is different from the red shale above (labeled Mineralization 1 and 2): MIN1 MIN2 Anyway, I guess my point is that I visited a road cut that is close to home, easy to access, and where I was told there should be no fossils. I found quite a lot to look at and ponder, and best of all, despite being parked on the roadside for 3 hours, I wondered if I would receive a visit from curious police but not at all so I felt very comfortable, except for the times when I climbed some very steep sections and found it a bit tricky to make my way back down the steep crumbly slope (I got down by choosing a section that had small samplings and used those as grips on the way down). I'm still not sure what else might be here or at other roadcuts but I have a hunch that this must be what fossil hunting in "dry" tree and plant areas might be like, since all the sources claim that not many dry forests were preserved as fossils because there wasn't much mud in the dry areas and they almost needed to be buried in a rockslide or freak flood to be preserved. Paleobotanists also suggest that the fossil record is heavily weighted toward wetland plants and trees so anything that comes from what was originally "dry" forest or meadow is worth inspecting.
  15. This is the 5th in a series of fossil ID questions - this one relates to two stick shaped fossils collected on our Sept. 16 trip to the 380 million year old Devonian site in Juniata County, PA. Devonian plants and trees are hard to find in Pennsylvania because so much was underwater however there were sticks and twigs and stems that did sink into the mud and get preserved. The question is, did we find two of those during our Juniata trip? Are these stick shaped fossils from plants or trees, or something else? Opinions, please... This stick shaped sample has a long thin piece extending at the bottom which appears to be part of the main fossil, which may (or may not) offer a clue: Here is another fossil from the same site/trip which has a similar form factor - it is in green shale - this bulges out a bit at the base:
  16. Hey Everyone! Can someone tell me what type of tree or plant this leaf is from? I found it in my creek in northern VA. Thanks.
