  2. Carboniferous leaf and seed fossils from Donbass region

    Dear Guys, Last september I was in the coal quarry in Donbass region, near Donetsk and found these leaves and one seed fossil. The majority of leaves are from seed ferns but other remains are unidentified. Please help to identify the taxons (also seed fern genera or families) if you know more about Carboniferous plants. Best Regards Domas
  3. Clams in coal shale ?

    Found on a coal shale dump near Jolliette, PA. Fresh water bivalves ? Marine bivalves washed in during a transgression ? Or could they be Branchiopods ? Other ?
  4. Possible seeds in coal?

    Hi all, I have a "lump" of coal which I found at the side of a playpark many years ago and have never been able to identify the tiny fossilised things inside. I'll attach pictures I've taken down a dissecting microscope - the brown circular things are 1mm in diameter and the only other fossilised section is a 5mm wide length of something (possible plant stem) which is incomplete at both ends (and therefore not very useful). Hope someone can maybe give a suggestion or 2... Thanks in advance! Also, sorry if pics not that good...
  5. Anthracite coal

    From the album WhodamanHD's Fossil collection.

    A large block of anthracite coal with no visible plant impressions. I found this near a abandoned railroad track in Mount Airy, Maryland.

  9. Pennsylvania Ferns

    Well it seems that St. Clair is closed for fossil fern digging but I wanted to know if anyone had a status on Carbondale. I found this: The website that @Fossildude19 appears to be outdated. I also found: Sue used to live in PA and her specialty was ferns. I sent her a message about her discoveries and locations. Hopefully Carbondale isn't closed to the public. There has to be some place in eastern PA that is open to the public that has some decent ferns.
  10. Folly Beach Fossil and Shell Hunt

    A few pics of the fossils and other things we found at Folly yesterday morning (at high tide no less ). We also got a lot of great shells and shell pieces, two new horseshoe crab shells (complete), and a spider crab shell (I believe that's what it is), and some corals. One of the shells Toby found that is complete is the olive shell - SC's state shell! It appears that I found coal, and possible charcoal (looks like wood on one end), so that was pretty cool! I can safely say I've never found coal or charcoal washed up on any beaches before. As far as fossils go, we got some great bone frags! They are pretty big and one of them has matrix with something else stuck to it. Debating on possibly trying to remove the matrix to see what that something else is. We also found, at the same time (we almost dove for it once we saw it - instantly new what it was! LOL) a chunk of what would have been a HUGE meg! The chuck itself is 3 inches on the diag! WHAT! So that was exciting. Toby swears he had an angy as well but dropped it in the water by mistake (I think he was trying to clean it off). I went to look for it when the waves regressed but wasn't paying attention and got soaked from the knees down. LOL I also picked some great concretions I found interesting. I also found a sea urchin! It was completely emptied on the inside so no life left. We did rescue one horseshoe crab and a sea star that were still alive and returned them to the ocean. Hope they made it! But the best part is we had a great time - about a two hour walk on the beach. The weather was amazing! Slight breeze, but not windy so no sand blowing in our faces. Temperature was perfect! Sun was out... What an amazing day! Hoping to make it back out again this week so we can go during low tide and hit those low tide lines. We have too many plans w/family for parties and Xmas gatherings this weekend to hit low tide now.
  11. Stigmaria Ficoides

    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.
  12. Is this a trilobite?

    Greetings! I found this imprint on a large piece of what I assume is coal on the beach in SC. Sand was dredged from offshore to replenish the beach, and there are fossilized teeth of deer, mammoth, mastodon, tapir, megalodons, etc. Nothing nearly as old as a trilobite. A lot of heavy coal pieces were on the beach after hurricane Matthew and I found this imprint on one of them. Can anyone tell from this image if it's a nothing or a something? (Pics were tricky, but can take more if needed and if image file too big I can squish it down.) --Stilitano
  13. Scouting trip

    My wife and I went on a scouting trip in NC today. Unfortunately we found no shark teeth, but we did find a lot of mosquitos, looks like a piece of petrified wood and what I believe is a chunk of coal.? On to SC this weekend to check out some new sites.
  14. Clifton (June 2014)

    As I promised myself, this has now become a yearly trip for me. As I'm getting ready to head out soon, let's reminisce on a previous trip that happened on one, if not THE hottest day of June of 2014. ..as one comes down from the wave breakers near the wharf of Stonehaven I checked the weather for that day and I knew it was going to be a hot one, but I never anticipated what hot was in this area. I've prepared but soon to find out I could have been more careful. But I digress. Moving on. If you've been keeping tabs on my previous Clifton posts, you'll remember that these layers are mostly perpendicular to each other, almost perfectly horizontal observed in short distances. The Sandstone tends to meet with meandering bodies of water. When you walk, you'll mostly see the rock layers as shown from the pic above, and then bam, you'll get to see this: The lenses show bodies infilled with different clast size, forming sandstone and/or mudstone type filled channels. Here's what I see when I look at the photo above: Close up Water channels that move, in perpetual motion, migrating this way or that. Interesting features as one tends to keep a closer eye for any sign of trackways. The strata in Clifton also contain in situ wonderful tree specimens that rival the ones at Joggins, at least in size. I can't recall if I've encountered one tree in Clifton that had been scared by flames such as in its almost twin in Joggins, but I'll have to make note next trek. When you're lucky enough, you will get shale that can be split without destroying the whole sample. The fragility of some makes it tough to be able to conserve in one piece but it happens from time to time. The details on some of these plants are exquisite. There are a few other places in New Brunswick, such as Minto, where plants have been perserved in similar high contrast. I haven't had the time to delve into naming different members of specific genus or families, but that will come soon enough. This is an interesting fella Calamite, annularia... As the Sun started beating down on me and my water reserve severely depleting, I turned tail and made my way off the beach. These cliffs created a dead zone as no current was passing through and I could feel the full brunt of an almost 40 degree Celcius heat. By the time I had made my way up and recovered, I've realized how close I came to having a heat stroke. Hospitalization would have probably happened. On my way back to Moncton, which was about 3 hours drive back South of the province, the heat had taken its effects on me and luckily my parents lived on the road on the main stretch. I stopped and rested for a while to try to recuperate and gather some semblance of strength and finished my trip. I think it is in the cards to bring at least a partner next time I go. There is a whole lot to do in Clifton and there are many opportunities to explore in this locale. The main thing beside shining a spotlight in this geographical treasure trove, is to have locals made aware of how important this site is for not just New Brunswick, but for the entire scientific community. There is some work being done on some discoveries made in the recent years, but there is vast potential to make more. As long as there is interest, people will keep being drawn to this forgotten shore where once vast forests doted the land, offering life and shelter to its many denizens. The search continues. - Keenan
  15. Pyrite Decay Test

    I have a bunch of petrified/coalified wood from Mazon Creek and have started a process to decrease the reactivity of the pyrite and sulphur in them. Thought I'd describe the process and results in case it is helpful to anyone else. Some of them are fairly quick to form decay and even create lovely hairy crystal gardens of possibly Pickeringite or Halotrichite. Here is an earlier post about that. Here's some images of the cool crystal hairs that formed awhile back. Anyway here's my process that I've started on a few items. Not at all sure if this is the best process but thought I'd try it as an experiment and see what happens. It is an adaptation of recommendations by Reiner Mielke. Any suggestions or critiques would be great. I'm currently at Step 4 with the first batch and debating about Step 5. Step 1: Neutralize in water with some baking soda. (I notice my pieces really fiz a lot and some of the material breaks a part in this reaction so one may need to be careful with fragile items.) Step 2: Dry in the oven at low temperature for several hours. Step 3: Immerse in WD-40 to displace all the water. Step 4: Let dry Step 5: Two options and I haven't decided between the two: One option is to immerse in motor oil. (This is the Mielke approach) The other option is to spray with Fluid Film (a lanolin product in a spray bottle to prevent rust) Then let dry.
  16. For those in the Illinois area. ESCONI's friday (June 13) meeting will feature an interesting talk about the large intact Fossilized Forests that have been found in Illinois recently. My understanding is that in 2007, the large fossil forest in the Herrin Coal was found and studied. And then in 2012, an even larger one was found in the Springfield Coal. I've linked articles about both of these forests. ESCONI General Meeting 8:00 p.m. College of Dupage, - Tech Ed (TEC) Building, Room 1038B (Map) Topic: Snapshot in time – Geologic Secrets of the Springfield Coal Fossilized Forests Scott Elrick, from the Illinois State Geological Survey, will describe a 300-million-year-old fossilized forest, found along the Galatia channel, an ancient river that flowed across southern Illinois. This ancient forest is the world’s largest intact rain forest from the Pennsylvanian Period ever to be discovered. Preserved along 150 miles of the Galatia channel river banks, the forest’s sheer size offers an unprecedented view of ancient forest life and diversity. Discovered in the roof of multiple underground coal mines, this rare find, opens a tantalizing window into the past. The forest plants and their encapsulating geology reveal much about the ancient environmental conditions during the time of their formation and about the coal they left behind. Scott will describe the geology surrounding this amazing underground discovery and the geologic and climatic factors that led to the remarkable preservation of this fossil forest. Some articles on the Springfield Coal Forest from 2012 Article with a nice slide show of images about the Springfield Coal Forest.

  17. What Is This Object In Coal?

    I was wondering what this is! it looks like a piece of bark, with a pickle-like skin. It kind of resembles some kind of slug, as there's some symmetry. What I don't understand is why it hasn't coalified like the rest of the coal around it? It readily came out of the piece of coal, and the coal was compressed around it. I broke it in half (I was so curious as to what it would look like inside), and it's like stone. Thanks!

  22. 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
  23. 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!
  24. Someone searching the Maritimes for nice articulated plants would ususally end up being referred to known fossil localities in Nova Scotia such as Sydney, Cape Breton. The ferns and other flora found in the coal rich cliffs of Cape Breton are of exceptional quality, but what if I tell you that there's a location in New Brunswick that yields specimens that matches in quality? This province has made many contributions to the field of geology and paleontology since Mitchell and Gesner in the 1850s and the days of the Stonehammer Club. There had been a lull for decades, but with the surging in geotourism and the newly founded Stonehammer Geopark, new research has been made on old and new sites alike. One such site is located in Clifton. Rule of thumb here is that West of Bathurst the rocks get older, and younger East. The sedimentary rocks at Clifton are pretty much around the same time period, late in the Carboniferous (~310 to 300 Mya), matching paleoenvironment. Clifton, New Brunswick (circled in red) As my list of grew longer, Clifton stayed on top of it. When Matt called me and asked if I had any plans that weekend, I suggested that we could head up North. He hasn't been in tha area either, so this was the perfect opportunity to go snoop around. We left Moncton Saturday morning and headed North for Bathurst. The car ride to reach Clifton took a little over 2 hours. Reaching Bathurst, we took Highway 11 and proceeded North-East. We passed Clifton to get to Stonehaven where there is a road leading to a wharf. I parked the car, got the gear ready, and went down the rocks forming a breakwater to get to the beach. It was a bit tricky and the tide had just started going out. Facing South-West, towards Clifton Facing North-East, towards Stonehaven We barely set foot on the beach that we came across these beauties. These tracks were probably made by an arthropod, most likely from a horseshoe crab (limulids). What's interesting is how these animals moved (seems to be more than one animal making these traces in the silty material). We'll have to look further into this, but its obvious that this paleoenvironment was influenced by some sort of salt water body, if these animals were indeed ocean dwelling organisms. Parallel prints with tail drag We carried on and stopped at a few easy accessible spots before having to crawl and tread carefully around slippery seaweed covered rocks. Me! After a few slips, bruises, bloody scratches, and wet boots, we made it to where we wanted to be. The cliffs are somewhat similar to other familiar sites such as Joggins in Nova Scotia. The strata of sedimentary rock have a marginal inclination of about 5 degrees. What surprised us was that we found some trees in situ, popping out from the cliffs. Several trees we've seen were pretty well preserved, and a couple up to a meter in diameter. Matt kneeling beside a big tree! Checking for trackways Within these cliffs are gorgeous ferns and other type of plants belonging to the Carboniferous Period. The plants are found on a light gray shale. There are sections of the cliffs that have talus piled up with lots of plant material. Clifton is an interesting site and may yet yield really important information that could form a more detailed picture of the paleoenvironment of the region. The plants, the trees, the terrain, the bodies of water dominating the landscape, and the animals leaving their traces. The information that we were able to gather that day will be shared with the rest of the community. Clifton has come up a few times in scientific literature, but has like most part New Brunswick, been understudied. We realize that the resources aren't always available, so people like me and you can be the foot soldiers and help the academic community by making these type of discoveries like we did today. Till next time. Cheers! - Keenan
