  1. I found this in the Green River near Black Diamond Wa. It appears to be a seed pit? or can it be something else? Geologic age is Tertiary
  2. 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.
  3. Cretaceous ,seed - Hell Creek

    Out at a hadrosaur dig site and came across this seed. Can anyone identify it? Thanks for looking!
  4. Seed?

    From the album Carbondale, PA

    I found a whole plate of these, but somehow only the one example made it home. 13mm long Carbondale, PA Lewellyn Formation Pennsylvanian period 299-323 myo
  5. Trying to ID this type of fossil

    Please forgive me for my fossil ignorance, as I do not know much about them. I am trying to find our what kind of fossil this could be. Or maybe it isn't. I'm not sure. I have looked on the internet for awhile and found nothing really similar to it. If this is easy and I'm just an idiot, I'm sorry haha. Just thought you all could help me here. Thank you
  6. Carboniferous seed?

    Hi everybody. Recently I found this fossil in the coal measures, but I don't know what is It. Maybe seeds? What do you think? Regards Juan
  7. Seed and Coprolite?

    Yesterday I looked in my batch of unattended rocks and found one very mixed fossiliferous rock I had been meaning to explore. These are two of the specimens I found inside:
  8. Brought back from the site 7/6. Seed?
  9. Northeastern Ohio - Seed?

    Here is another found this past summer. The first two are counterparts to each other. It is raised, like an almond. I wonder if the third is what it looks like inside??
  10. This again is small, but I believe it is another of the Cardaites Seed?
  11. Brought this one home, and again, am not sure what it is?
  12. Hi everyone, Here is another mystery fossil we found last June while on a Forest Service dig in South Dakota. It was found in an area that we think was once a shoreline, since the matrix ranged from sandy to iron-rich conglomerate layers with both aquatic (rays, gars, turtle, etc.) and terrestrial fauna (hadrosaur, T. rex, thescelosaur, etc.). Our best guess is some kind of seed, but we really have no clue. I forgot to take measurements when I was at the lab and no longer have ready access, so I apologize in advance. It is pretty small - you should be able to get an idea of the size from the adjacent Xacto knife (8 mm dia.).
  13. Found today, any ideas?
  14. Cardiocarpon also called Samaropsis

    From the album Carboniferous Fossils-Ohio

    Northeast Ohio
  15. PENNSYLVANIAN Seed

    From the album Christine's collection

    Found in Mazonia Braidwood, Illinois. Carboniferous.
  16. Some Sorta Nut?

    Hi everyone! When I was a little kid I found this fossil while swimming in Lake Cumberland in Kentucky. I've always cherished it, but now I kinda what to know what the heck it is! I'm guessing some sorta nut or seed, but I'd like to get more specific answers. Any ideas?? Thanks!
  17. Fossilized Tree Seed?

    Hi everyone, I was browsing the forums and came across a post (http://www.thefossilforum.com/index.php?/topic/51360-fossilized-figs/), since closed, that reminded me of some possible tree seeds that I found in the Hell Creek Formation of Montana, in the same chunk of sandstone as a small t rex tooth. The "fossilized figs" originally posted in that topic didn't look like a fossil, but later on there was a link to someone selling fossil figs on ebay: http://www.ebay.com/itm/Fossil-Fig-in-Matrix-Lance-Creek-Wyoming-Dinosaur-era-/361133992105?pt=UK_Collectables_RocksFossils_Minerals_EH&hash=item54154368a9 Long story short, I don't know much about plants, but the shape, as well as the similar age and location, reminded me of my "tree seeds." I have two views of the first: Here is another: So, do I have some fossil figs, or fossil seeds, or just seed-shaped rocks? Thanks in advance
  18. more big brook nj THANKS! for all your input
  19. I found this while fossil hunting yesterday. The exposure I was hunting in is close to a creek shore, and it's obvious the water level rises to its height by the rounding of the nearby stones and the fossil itself (evident on its backside). Other finds in the same area included mostly coral and brachiopods, as well as pieces of coal. I'm no expert on fossils, but when I found this the first thought was a nut shell or seed. But, I know you don't find nuts during this time period fossilized, especially anything this size, and I can't even tell what type of modern day nut it resembles. I then thought it was possibly the underside of a shell, but it has two distinct protrusions inside which twist together, again resembling the inside of some type of nut or seed. Basically, I don't know what this is and would appreciate the help or thoughts. Thanks
  20. Mazon Creek - Seed

    Hi Folks- I had this beauty open last night and wanted to get folks opinions on an id. Stay warm! Evan
  21. Seed In Amber? Or Something Else?

    is this a seed in amber, or something else? it is in the same piece as the unidentified insect i posted somewhere else in this forum. here is a picture:
  22. Walnut Shaped Oddity From St. Clair

    Trigonocarpus (Seed) from St. Clair PA This is a walnut shaped fossil discovered Aug. 30 at the St. Clair, PA Carboniferous fern site. This was found by Nan while she was looking for insects/traces - assume it is a fern seed (trigonocarpus is the morphologic genus given to fern seeds) but we haven't seen this one before. It is about 3 1/2 centimeters long: Here are some closeups:
  23. Triassic Seed/cupule?

    Found this gorgeous little fella today in some Triassic sediment that had eroded out of a cliff near here. It was in a layer that also had a lot of Dicroidium leaves. I thought it might be a cupule, just looking for an accurate ID. Cheers,
  24. Fossil Fern Cupule - Archaeopteris?

    I've been pondering this fossil from St. Clair and it looks like a "cupule" that encloses a seed or spore and I'm thinking that it might be cupules at the end of a node - maybe archaeopteris. Is anyone familiar with these fossil plant cupules who might shed some light on this? One of the very surprising things we're learning about fossil plants (Pennsylvanian) is that many of the ferns and horsetails had different shaped leaves or leaf configurations on the same plant, such as the microphylls on the trunk, cupules that enclosed seeds, and young round leaves versus older elongated leaves (neuropteris for example). Still learning about paleobotany at St. Clair where we've been collecting - fascinating.
