  1. Ive been through a bunch of crab concs lately and most of those are what I call 'problem' crabs. some are just pieces of junk as far as im concerned. I did get one really good one finished up for my son and I also finished up one 'sticky' crab that turned out really good for me. One for the collection. Anyways, I went though some more crab concs today and found what I think should be some purdy good crabs? Time will tell. Here are two pics of some crab concs ive got glued up. The 4 should be purdy good, but the two on the side I have really high hopes for! One crab, the bigger one is a Pulalius that has the tail end sticking out. The smaller one is an Orbitoplax that looks very good. That one, if it turns out nice is for my youngest son. My fingers are crossed. RB
  2. This tooth was self collected at a personal site close to home. This site produces exceptional micro material. H. elongatus are very uncommon teeth in the Eocene of N.C.
  3. This tiny echinoid; 6.21 mm by 4.31 mm is extremely large for the species. Most range between 2 and 4 millimeter. The measurements were taken while taking pictures with my digital microscope. They are an uncommon find by most collectors. Seeing them in situ is extremely difficult unless the sediments have been very well weathered. Most I have found are from matrix I collected. The last picture of the 2 is meant to show the size range of these. The smaller one measures 2.68 mm long by 1.74 mm wide; and I have a few even smaller.
  4. Hi all, I had a chance to visit one of my favorite eastern North Carolina quarries today. This quarry contains exposures of the Cretaceous PeeDee Formation and Eocene Castle Hayne Formation. Overall was an outstanding day for everyone who attended. I was very fortunate to add 2 new species to my collection. First and my best find of the day, a Baculites vertebralis living chamber. Baculites along with all ammonites are extremely rare in North Carolina so this was an unexpected and day making find. Find of the day #2 and barely #2 an extremely rare Cretaceous echinoid, also a first for me. Lefortia trojana I also found more than a few Hardouinia kellumi's. An uncommon Cretaceous echinoid. From the Castle Hayne Eocene, Linthia wilmingtonensis. Unifascia carolinensis I also found this large, softball sized Cretaceous clam cast, from the PeeDee Formation. Trying to find an ID for it. There was lots of other things. 25 or so Hardouinia mortonis, a few shark teeth including 1 nice Squalicorax. Also some cool oysters, Flemingostrea and Exogyra and a real nice cretaceous angel shark vert, that I am having trouble photographing. I also captured this cool pic of a dragonfly taking a break. Great day in the sun, getting some good exercise finding fossils. Cannot ask for anything better than that.
  5. It is my pleasure to quote Auspex: "Messelornis is often incorrectly referred to as the "Messel Rail". Although rails are in the same order (Gruiformes, along with the cranes), its closest living relative is the Sunbittern of the American tropics. There are four named species (of two genera) in the family Messelornithidae: Messelornis cristata (only from Messel), M. nearctica (from the Eocene Green River Fm., USA), M. russelli (from the Paleocene of France), and Itardiornis hessae (from the Late Eocene-Early Oligocene fissure-fillings in Quercy, France). According to Gerald Meyer in Paleocene Fossil Birds, there are over 500 specimens of M. cristata known from the Messel pit, constituting roughly half of the bird fossils found there. Interestingly, no juvenile specimens are known from there, which suggests that they did not nest nearby." Would need some prepping - there is still a sand limonite layer on top of the bones.

  6. I was inspired by recent posts to visit the canal spoils near Yankeetown, Florida. I did not, unfortunately, find the echinoid riches described by others. However, I did find a muddy, suspicious-looking rock, which, when cleaned, looked like this. Can anyone please help me identify this pretty little coral? Edit: I am told below that this may instead be a burrow cast. Can anyone help to identify it?
  7. Again, my wife brings me a crab and tells me that I brought it into the house a few years ago? Apparently I forgot about it. Anyways I looked at it and realized that I had prepped it out many years ago and could easily see that it need some serious clean-up! Took me just over 3 hours to clean it up but it sure came out quite nice for this species of crab! Amazes me how patience now later in my life can do a better prep job. It was a 6 legger with no tippy tippys and now is a 7 legger with 3 tippy tippys. Quite nice! These are not easy to prep and this one is much better than most. Usually the shell material wants to come off. This one, the shell material stayed on. Just a really cool crab. This crab is Orbitoplax weaver, comes from Oregon and is Eocene in age. Im quite happy with this one now. Get a load of the eye stalks!!! Wow!!! Oh, and thanks to Aerogrower for the cube with the letter W. weaver. RB
  8. Ive been off and on working on some very sticky crabs these last few days. I don't like working on them but they are great for what I call 'gas crabs'. You can still get good crabs from sticky concretions, but they do take more concentration and more time. Only bad thing is,,, if it turns out to be a very bad crab then you've just waisted 3, 4 hours or more. I did just that the other day. Took about 4 hours to get the carapace exsposed and find the claw and legs on the left side, then found nothing on the right side but 'crab bits'. Finding crab bits is almost always a very bad thing! So I simply picked up another 'sticky' crab and went to town. Here is what ive done so far on this one. No telling wether or not I will finish it, that is up to the crab. RB
  9. Found these near Princeton BC. Any idea what they are? Thanks.
  10. I was doing some organizing and clean up on my prep bench today, just to make room for me to prep. I have a real bad habit of starting a prep project and then putting it aside for later and starting another prep project. Anyways, I ran into this one today. I have no idea how long its been sittin on the shelf above my bench, but a few years at least? I went through all the pieces and cleaned them up and started the 'gluing' process. This one is going to be a 'gas crab' for sure, but I think it may turn out to be a purty nice gas crab? Lots of pieces came off the top of this thing and those pieces have crab parts in them so fighting through the glue is going to be a job and much of the carapace shell is missing, but we'll see? My fingers are crossed. RB

  13. Hi all, Here another sharktooth, from Balegem, Belgium. From the Lutetian stage of the early Eocene (approx 45 mya). What's the species? Have a nice weekend, Max Closeups side 1:
  14. I am always 2nd guessing when I prep out crabs. I had high hopes for this one, but,,,,, you can never know for sure till you get lots of the crab rock removed. This one was in two halves and glued back together. Lots of glue to get through and at first once I put in about 4 hours or so it wasn't looking too good. Also, I cant see a rear end on this thing. That's always bad in my book. I knew there was more leg on the left side, just wasn't sure where or how good they might be? Wasnt sure at all about the legs on the right side either? In this first pic all I had was 3 legs. Some leg is always better than no leg, but for me, I want all 8 of them! Doesn't happen too often. Heck, almost never! Part of the carapace was also in the upper part of the rock being that the crab was somewhat sticky when my youngest son 'wacked' it open. So it looks a bit beat up. I can fix that though. I don't like having to 'fix' things, but that's the way it goes sometimes. RB

  16. April Fools Day I took my wife, our buddy and his son @Daleksec and 2 local Paleontologists on the boat along the Pamunkey River for a little fossil hunting and stratigraphy lesson. Unfortunately, we had heavy rains the day before which drove up the water level a few feet and kept us from exploring the site where Daleksec found his February VFOM . Here are 2 photos of Daleksec's and his dad's finds, all collected in about an hour. This was a new spot for me that I had never collected before but the Paleontologist who is the stratigraphy expert put us right on the spot. LOCATION, LOCATION, LOCATION!!! The first 3 teeth found were pre-megs in less than 5 mins. This area we collected is Lower Calvert Formation (Miocene) sitting on Old Church Formation from the upper Oligocene. We also hit another spot that has a nice Piney Point exposure from the middle Eocene with Old Church and Calvert above. @Daleksec collected some of the oysters from the Piney Point and found this in the matrix when he cleaned everything up. Pretty impressive. He also found a sand dollar but destroyed (and I do mean DESTROYED) trying to remove it from the matrix. Remember @Daleksec, patience my young apprentice, patience. :-) Perhaps @sixgill pete or someone else can help identify it. All in all, not a bad day on the water. If I'm honest, any day I get to spend fossil hunting with my wife is a great day. I'm very fortunate that she has the same passion, though i do remember a time when I had a 10 handicap in golf. Obviously, we will be exploring the new spot some more in the near future. Don't worry @MarcoSr, I will definitely show you the new spot, after I blindfold you of course. :-) If @sixgill pete ever makes it up this way I would show him too, with the blindfold of course. Cheers, SA2
  17. Hi all, Is this a mako? In my opinion it looks a little bit like Isurus oxirhynchus, but I'm not sure. I know that it's quite worn, but still IDable. It comes from Balegem, Belgium (--> Lutetian, Eocene; 45 mya). Thanks for the help, Max Closeups side 1:
  18. Hi all, Is this a tiger shark? If so, from what species? For now I'm thinking Galeocerdo latidens, but I'm not sure... It's from Balegem, Belgium (--> Lutetian, Eocene; 45 mya). Thanks in advance, Max
  19. Hi all, Here some sharkteeth found in Egem, Belgium. From the Yperian stage of the early Eocene (approx 50 mya). Anyone have a clue on the species? Have a nice weekend, Max
  20. I just couldn't resist purchasing this Knightia, from the Green River Formation in Wyoming from a local craigslist seller. Yes I do troll craigslist a lot looking for all the coolest gadgetry. Well the lady I bought it from said it was gifted to her and that she had no clue what it was and didn't want it. She sold it to me for $10. I plan on taking a trip to the Green River Formation but just in case I don't make it out I decided to get this 7" beauty.
  21. My wife came into my office the other day and said "here is a crab you wanted me to put in a safe place" Wow!!! I was flabbergasted! This was 12 years ago. This is a very rare double crab in a concretion. These are Orbitoplax weaveri found in Oregon in the Looking Glass Formation and Eocene in age. Really really tuff to get a double crab! RB
  22. I don't usually write more than a sentence or two and sometimes a paragraph, but this will be a long one. This is also 20 years in the making. Way back when, I met a guy over the internet and made a crab concretion trade. After that he invited me to Washington for a crab concretion fossil hunt. I couldn't wait. I dragged along my intire family. Me, wife and 3 kids. My youngest son Coleton was 8 years old. Hes 28 now. I always wanted to take my kids on fossil excursions and get them out into mother nature. We get to our camping site where we were to meet this new fossil friend of mine in the late afternoon and its raining cats and dogs! My new friend shows up the next morning and we get packed up with all out fossil hunting gear and off we go. It was only about 20 minutes to get to the spot where we park and then,,, we hike down this canyon about 15 or 20 minutes and get to this little creek. We head down steam and within 4 minutes or so I see this little bank that has crab balls in it. Now im excited! My kids and I started digging out crab concs and my new friend was literally in the creek digging out another conc. I see that he picked one out and 'wacked' it right then and there with his little 4 pound mini sledge. A big piece broke off and fell into this overflowing creek. I had a heart attack!!! I tell him that he should keep each and every piece of a crab concretion. He looks around in the creek and finds one of the pieces. he then comes onto shore and then,,,,,, gives it to me and says I can have it! First time anyone has givin me a fossil for free and I feel overwhelmed. What a freakin nice guy. I wasn't expecting that. Anyways, we begin to go downstream again. We had to clime over a huge log jam and kept working our way down stream. I was lagging behind. I was already a very happy camper having several concs. I had one of those carpenter tool belts where my pick hammer hung onto a metal loop. I was walking along a very slippery sloping bank and slipped. I landed on my pick hammer onto my left ribs. I layed there and realized that if I didn't take a breath I was going to pass out. I finally was able to take a gasp of breath! I looked over to my left and saw my youngest son just going around a corner in the creek. I figured I was going to be there awhile. I could not move! I hurt really bad. Also, my feet were in the creek and the water was cold enough that if you stayed in it your feet would become numb! I knew they would be back at some time, just didn't know when? Well, within a few minutes my son came around the corner, saw that I was in bad trouble and went and got the other two guys. They took my backpack and helped me to get up. it took me about 3 hours to get back up the creek and back up the canyon to the trucks. Every step was nothing but pain! Especialy each left step! The next morning I had the biggest baddest bruze on my left sife the size of a basket ball!!! Even the drive home was super painfull! I was about 12 hours from home. Took me about 3 weeks to be able to really get around again, but slowly. Two things, my new friend gave me several concretions and my 8 year old son had the thought to check up on his dad. Brings tears to my eyes!!! I don't remember any of the other crab concs, but the one my buddy found in the creek and gave to me is now something special to me. I was still purty new to prepping fossil crabs and here is a picture of this one. Back in those days I didn't have a whole lot of patience and was always in a hurry to get things finished. Not a good thing. While I was putting my fossil display cabinet together the other day, my wife came in and asked why this concretion was not also in the cabinet. I told her I could easily see that it needed a lot more work and that this one was one of my early crabs. It is now being more proffesionlay prepped. Just wish I could spell? Ha!!!
