  6. 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.
  7. Green River Fish Prep

    I'm working on some Green River stuff for @abctriplets that they collected on their fossil extravaganza! Thus fish is turning out to be a real gem. This is how the piece arrived in Texas. EDIT: 1st two photos courtesy of Jared. I applied copious amounts of Paleobond to both surfaces and clamped them together for several days, marking the location and direction of the fish so I don't forget. Then I went on the attack. The fish layer was about 3/4" below the surface so I used a small chisel and knocked about 1/2" off the top of the slab to reduce the depth. Then comes the CP9361for fast bulk matrix removal, being careful not to hit the fish. There is a very slight color change (darkening) to the matrix immediately before you expose the fish. Once I saw that, I switched to the Micro Jack knowing that the fish is anxiously waiting to fall apart just below the surface! These fish are extremely brittle so I'm stopping every 30 seconds or so to consolidate. Scribe, consolidate, repeat... 2 hours later and here's where it sits. I believe this is a Mioplosus sp. and it looks like it will be complete. You can see the glue where the break ran across the skull and down the body.
  8. Fish out of water

    This is just a mildly interesting video I found on Youtube. Sorry if it isn't in the right category, as it isn't directly fossil related. Description (given by the video): Around 400 million years ago, fish left the water and started to evolve into land-loving creatures. But how did the transition happen? A new and unusual experiment could shed some light on the kinds of changes that enabled fins to become limbs. Researchers took a fish species known to be able to walk on its fins from time to time, and raised it on land. Watch the fish promenade in this Nature Video. Enjoy!

  9. Bandringa rayi or Bandringa herdinae? Brand new to site - thanks in advance for any assistance here.
  10. Fish fragments???

  11. A possible fish fin?

  12. Fish tooth?

    Hi all, I found this really weird thing two days ago on the Zandmotor (Netherlands). I think it's some kind of fish tooth, because (even though they don't look like each other) I think it might have had the same function as the Eotrigonodon fish teeth. Most of the fossils from the Zandmotor are Pleistocene, but sometime Eocene fossils show up (such as shark teeth). So it could be either. The thing is 3 mm long. Anyways, do you also agree with fish tooth? If yes, any clue on the species? Thanks in advance, Max

  15. Repairing: fish and hyena jaw

    Hi all, These two have been sitting on my desk for some time, as I kept on forgetting to ask this. Now I finally remembered. I once made a trade with a fossil-lover in Singapore, but unfortunately the fossils arrived broken, having not survived the trip. The two broken fossils I got were: a partial Lycoptera davidi, and a small jaw piece of a hyena. I didn't dare take out the fossils of the bag yet, as I was scared I would lose some of the broken off pieces and damage the fossils even more. Here they are: The damage on the Lycoptera isn't very severe; only a big block of matrix got loose (the fossil itself is still intact). But the damage on the hyena jaw is very bad: the big tooth split in two, and many other crumbs here and there. Here is what the jaw looked like before: I was wondering: is there a way to repair the fossils? As in stick them back into one nice piece? I can buy necessary material if it is cheap. Note that this would be my first fossil repair, and I have no experience whatsoever in the subject. Thanks in advance for your help, Max
  16. Talbragar Fish Fossils

    Hello! This is where I will be posting the best of my Talbragar Fish Beds collection over time. The site is near Gulgong, NSW Australia. They are from the late Jurassic. 1. Cavenderichthys talbragarensis, named after and endemic to the site (so far). This is probably my best specimen from the site, it is complete, large, and white. Continued...
  17. fish/reptile jaw section?

    I bought this a few years ago at a local show. It was mixed in with a bunch of small Otodus and sand tiger shark teeth. I don't remember if the vendor said where they came from and I didn't write it down, but I think Morocco is likely.
  18. Can't identify this.

    Can anyone identify this? Found at Filey beach, Uk. Along the base of the coastal wall. I'm guessing some small fish bones or a partial bug fossil, if even that it could be just nothing, thanks. The rock is the size of my palm so this comes out at about a 10p coin here in uk
  19. Coelacanth Prep

    @Jeffrey P has issued quite a challenge with a request for preparation of a small coelacanth. This little guy appears to only be missing the tip of the head. Unfortunately, the rest is under a thin layer of diamond hard shale! Here's a pic of the specimen as it arrived. Where's Waldo? Only parts of the skull are exposed with a hint of the caudal fin under the matrix. Here it is after 4 hours of prep. This guy is a textbook example of sticky. I'm switching between 3 tools to prep this. I start by removing about 1/2mm of matrix with the Aro. This is kind of like doing dental work with a jackhammer but if you're careful, it will get you down to the later just above the bone pretty quickly. Then I switch to the Micro Jack. The problem with the scribes is that the matrix turns white when you scribe it... and the bones are white! I scribe away for about 10 minutes with eagle eyes out for any hint of bones (this uncovers an area about 5mmx10mm) and then hit it with abrasive to knock off the scribe marks so I can see the bones against the matrix.
  20. Fossilized fish ID needed

    Hi there, I'm thinking of buying these fish but the seller knows absolutely nothing about them. They look like they are from Green River. Just wondering if an ID can be given; genus or species if possible. Thanks!
  21. Stingray info

    I apologize if this is a dumb question, but I inherited this large fossil years ago from my late grandfather. Any info you may have regarding origin, value, etc Woild be greatly appreciated!!
  22. Found on Venice Beach FL

    This was found on Venice beach FL. I know it is not a fossil but curious as to what it was. Thank you
  23. Fossil photography help

    Hello! I have a fish i'm trying to take photos of, and they always come out blurry and the lighting is horrible. Its quite hard to do when the fossil is the same colour as the rest of the rock. Any tips? I know I'm being kinda vague and I don't really know how much you guys would be able to help . If you need any more info in order to help, just let me know. Thanks
