  1. Here are a couple of "old" pieces from St. Clair that I found. The first one is a faint trace that I think is Pectopteris but I find it so rarely at St. Clair I can't tell for sure. What is throwing me off is that the leaflets are getting longer as they progress along the rachis whereas I have always thought that Pectopteris had a consistent leaflet length along the whole leaf. Then the second piece is a cluster of leaves/leaflets that don't match anything I've seen before. The tips of the leaves are not pointed enough for Alethopteris and not wide enough for Neuropteris. Any suggestions are appreciated.
  2. Mazon Creek Ferns

    I was looking over the Smithsonian collection of Mazon Creek ferns tonight (http://paleobiology.si.edu/mazoncreek/mazonGroups.html). It seems like most ferns are labeled as Pecopteris species, but that there are a number of very similar fern species. Is there a good reference that breaks down the different species and how to identify them? I have Richardson's guide, but that is just for the fauna. Thanks!
  3. Carbondale Pa

    An enjoyable and productive outing with Jeffrey P, my first to the carboniferous. Id's welcome. Gordon See pattern to right of coin
  4. Large Pecopteris sp. Section

    From the album Cory's Lane Fossil Locality

    Large imprint of Pecopteris sp. Found in 2017 at the Cory's Lane fossil locality, Rhode Island.
  5. The Ferns are Growing!

    Well... I seem to be turning into a Rhode Island native at this point. This past weekend I was able to head down to Cory's Lane for an afternoon of digging. Here's my latest find from the Carboniferous period. This fern still needs to be cleaned up a bit and I'm still trying to nail down an exact ID. At just over 3 feet long this is now my biggest and most complete find to date (1-upped myself again). More pics to come once I finish cleaning this guy up. P.S. This was definitely not fun to carry back to the car . I couldn't save the entire second half of this fern as it was partially destroyed when I ripped up the 8 foot slab of rock this fossil was on. I did manage to save the middle section at least!
  6. German plant fossil?

    Calling all plant enthusiasts (especially of the Central Europe variety). I purchased this plate from a tailgate sale a few years back and it has been sitting in my cabinet awaiting some sort of ID. The only information the seller could remember was it was from Germany. I have tried to search images online and can never quite come up with shale that looks the same. The matrix is a pale grey with plant impressions that are a pinkish color. For size reference, the plate is approximately 24cm x 13cm. Any ideas on this? Do you think it is even from Germany?
  7. eastern PA

    I'd like to go out to look for some decent fern fossils before the end of September. Can anyone suggest a spot or mind if I tag along with them?
  8. Unidentified Fern

    Hi All, I'm having a hard time nailing down an exact ID for this large fern imprint I found earlier this month. This imprint is from the Pennsylvanian time period and was found in the Rhode Island Formation. below I've included a list of the possible suspects/known flora from the Rhode Island Formation. It doesn't help that fossils from the Rhode Island Formation are often distorted. This distortion can be seen in the close up image of the pinnules below. The red arrows are pointing to pinnules I believe are the way they should look versus distorted. Anyone have any ideas as to an ID?? Thanks as always!
  9. I started collecting fossils with vertebrates, sometimes my friend and me we found fossil plants. But the plant fossils have less importance than the fish and amphibians, acanthodians and sharks ........ years later I became a gardener, graduated from the master school and asked me only the question ... how did it all start? When did the first plants keep the head out of the water and populate the still inanimate land? I rummaged through the internet, which I found first - Rhynia ..... and similar plants as Psilophyton ... now had suddenly the first finds of the Perm meaning, the puzzle grew, still growing ... every fossil is a Wonders how fragile plants can be, how wonderful, if we can find them as fossils. ..... Then I moved, now in the middle of the Devon and have a famous place of reference before the door ... Plants of Alken on the Moselle! I found some plants like Psilophyton and saw some collectors hunting for Trilobites...the plants had been thrown away,....perhaps they didnĀ“t know about it!!! Pity for them - what a blessing for me !
  10. Our Fossilicious Summer

    WHAT WE LEARNED IN OUR FIRST FOSSIL HUNTING SUMMER This is a short recap of what we learned on our fossil trips this summer, in our first 3 months as very new fossil collectors. This week, Nancy and I gave a slide presentation on our summer fossil hunting experiences, to the Delaware Valley Paleontological Society. We didn't realize it ourselves but in 3 months we visited 8 sites in Pennsylvania and New York including: Antes Creek, Deer Lake, Red Hill, Juniata County, McIntyre Mountain, Montour and St. Clair in Pennsylvania, and a very productive trip to Tully, NY. We visited St. Clair 4 times, which has become our home site. At St. Clair, we were astonished by the diversity of species - we collected well articulated samples of more than a dozen species including: Alethopteris, Annularia, Asterophyllites, Cordaites, Cyclopteris, Eusphenopteris, Lepidophylloides, Neuropteris, Odontopteris, Pecopteris, Sphenophyllum, Sphenopteris, and numerous Seeds, Bark, Roots. Most notably - I learned to pronounce all of these without stuttering! At St. Clair, we spent one trip looking exclusively for seeds trigonocarpus), and one trip looking just for roots (stigmaria). Our most significant finds have included very large (2 foot long) display pieces covered with well articulated orange ferns, an alethopteris seed attached to a leaf stem, and many Carboniferous leaves that have different shapes from traditional ferns. What we learned this summer has really helped us find some interesting fossils - here are a few things we did that helped a lot: 1. DOING OUR HOMEWORK. It helped to study each site in advance using Internet websites and books on fossils (Dave's "Views of the Mahantango" and "Louisville Fossils" are among the best, imho). Several universities also have great educational sites that bring each era to life in very creative and interesting ways, with lots of illustrations and photos. I like the UC-Berkeleyand University of West Virginia websites. 2. LEARNING FROM TRIP REPORTS. We read trip reports from other groups and individuals to see what they reported - sometimes this helps us stumble across new places to visit such as the site at Tully, NY and Deer Lake. 3. SETTING GOALS AND TARGETS FOR EACH TRIP. For each trip, we establish specific goals - for example we may look for seeds, or roots at St. Clair, or trilobites or shell assemblages at a Devonian site. Our interest right now is in looking for things that are scarce or rare, and fossils that are extremely well articulated (which is also rare!). We also like solving puzzles so eventually we would like to find things that help add to the fossil record in areas where there are still questions or missing links. 4. DISPLAYING WHAT WE FIND. Personally, Nancy and I like collecting larger fossils that we can display in mounts and frames, and we are also looking for larger pieces that we can display like sculptures - we have a few pieces that we drilled holes in, inserted wooden dowels that we stained, and then drilled/inserted the dowels in wooden trophy bases - all available from a craft store. This allows us to display thicker fossils esp. assemblages, like sculptures, and you can turn them around and look at all sides when they are mounted like this. 5. WE AVOID FOSSIL HORDING. We both agreed that we would NOT become "fossil horders" putting hundreds of rocks in boxes and sticking them away in the basement or garage - instead, we focus on finding display-quality items, and rare or scarce finds which we are slowly putting in frames. 6. DOCUMENTING OUR FINDS WITH CLOSEUP PHOTOS. We photograph everything we find as soon as possible after returning from a trip, using a digital camera with a closeup attachment - many times we find new discoveries while taking closeup photos and some of our best finds came AFTER we returned from the trip and inspected our fossils. I usually put the finds on a white background on an ironing board and use window light, nothing fancy, but it works. 7. FOSSIL ID. We post anything we can't identify on the Fossil Forum and are EXTREMELY grateful for the terrific response from our friends on the site! We are also accumulating a growing library of fossil books (some modern, some from the 19th and early 20th century) so we can identify more fossils ourselves without having to post on Fossil ID. 8. WRITING ABOUT OUR EXPERIENCES GIVES US NEW INSIGHTS. We report everything that interests and excites us about fossil hunting on Fossil Forum to share our experiences - and we find that writing about what we're doing helps us learn more and gain insights, just from writing about it. We have also started videotaping some of our adventures and are thinking about the best place to post some of these. 9. WINTER PLANS: COPING WITH CABIN FEVER. Our winter plans are to visit one or two more sites, then go into "fossil hibernation" and organize, identify and label fossils we haven't processed yet. We have a Dremel to do some light preservation work where needed. We are not planning to become "chemical conservators" - using chemicals to dissolve limestone and so forth - that's a bit too ambitious for us at this point. We may get involved in some interesting activities by local universities that are using 3D printing to process and replicate large dinosaur bones. We are also planning to provide an exhibit (on Carboniferous plants and trees/coal swamps) at a fossil fair in April. 10. RECOMMENDED READING: I enjoy reading fossil books - I'm currently reading with great interest a small book entitled "Leaves and Stems from Fossil Forests" by Raymond E. Janssen (1939) which I bought last night at the DVPS meeting, and a textbook entitled Introduction to Paleobiology and the Fossil Record by Benton and Harper (2008) (excellent book). The book that has been the most useful to me so far is the classic book "Fossil Collecting in Pennsylvania" by Hoskins et. al. (3rd ed. 1983). I am constantly re-reading the Hoskins book and find something new each time as my knowledge grows. A book that impressed Nancy and me is a large beautifully illustrated book entitled "Prehistoric Life: The Definitive Visual History of Life on Earth" (published by Dorling Kindersley, 2012) UPDATE (Oct 11): Nancy is taking some college courses which are prerequisites to enter grad school, so I am doing most of the fossil reading and ID. I read several books at the same time and other books I purchased that I am currently reading are: Paleobotany: The Biology and Evolution of Fossil Plants (second edition) by Thomas Taylor; and Introduction to Paleobiology and the Fossil Record by Benton and Harper. I guess you can tell from this that I'm reading up on fossil plants - my main interest is not just to understand the evolution and fossil record, identification tips, etc. - but also to try to figure out where the missing links and gaps are so if we come across something that adds to the fossil record, we will be able to recognize the value. What is most surprising is that there is a lot missing from the Carboniferous record - partly because after this period, many of the oceans and swamps apparently dried up and there were ice ages and other factors that caused mass extinctions. Here are some interesting things I have learned this summer about Fossil Plants and Trees: 1. More Carboniferous insect fossils and evidence of insects are needed (by the way, there are some GREAT current discussions about insects on this forum!). 2. Many categories of lycopsids and other Carboniferous trees and plants do not have verified associations between the leaves and seeds, or leaves and trunks/stems. Many trigonocarpus (fossilized seeds and "fruits") are found with leaves, but examples of seeds actually ATTACHED to leaf sprigs are rare (we have found one example of a seed attached to Alethopteris). 3. More Leaf and Bark Verifications are Needed. Another interesting thing I learned is that there are more than 30 different types of "scale tree" patterns but only half a dozen leaves for these trees - suggesting that a lot of different species had the same leaves - or - there are a lot of missing leaf types or the existing leaf types have not been matched to the bark patterns yet. 4. Another peculiar revelation is that most Carboniferous leaves that do not fall neatly into classic fern shapes seem to be lumped together as "sphenopteris" - we have many "non-traditional fern" leaf fossils that are VERY different from each other and obviously different species, but when we go online to ID them, they all seem to be grouped as "sphenopteris!" Maybe some of these leaf types match up with the bark patterns I mentioned. 5. Last but certainly not least is the insight that fern trees could have 2 or 3 different types of leaves on the same tree! This was really interesting. Also, some leaf types can come in different shapes - for example, Neuropteris can be round at the base of a stem and elongated along the stem and at the tip...AND...some paleobotanists now classify cyclopteris - the round fan shaped leaf - as a form of Neuropteris. This definitely adds to the confusion. I'm still reading and trying to understand all of this and these are only my initial impressions, which are still forming and there may be explanations for some of these questions that I haven't discovered yet but these are the questions that I am trying to answer by reading, and of course, by fossil collecting. I hope that many of our new friend (and I should add, VERY COOL new friends!) on the fossil forum will help clarify some of these interesting questions. Hope this is helpful.
  11. Some impressions from my private collection of permian fossils, some of them I digged myself, some I changed with other collectors, most of them I prepared myself the permian fossils had been found in Germany, Rhineland - Pallatinate niederkirchen , pdernheim and other locations
  12. In between all of the 4th of July weekend barbecues I was able to make it down to Cory's Lane, Rhode Island for a few hours of shale splitting. The day started out slow with only a few small plant imprints found, but I eventually managed to rip up a 5 foot slab of rock with a larger fern section on one end of it. After cutting the slab down to a little over a foot and a half in length this Pecopteris arborescens manages to go down as the largest fern I've found at this locality! It was a nice start to the long weekend, but the real win was the awesome weather .
