  2. How do you choose?

    Definitely quality over size, as other have said. Also as Tim said I too only buy at bargain prizes but I do find nice specimens at low cost. It all depends on what you after. Other factors may come into your decision too , like I don’t like matrix if has been sculpted, I like an natural association. On the subject of matrix, sometimes the positioning of the specimens can come onto account. I don’t have much of a budget , so I would prefer to a get a really detailed partial for little money than to get a large badly preserved specimen for lot more money.
  3. Fossil Preperation Help?

    Once you start down the path and really get to prepping, you'll find it is a maelstrom of costs. My lab is sparsely outfitted and I have spent thousands of dollars on it. The compressor is probably the least expensive piece of equipment I own.
  4. January 2020 - Finds of the Month Entries

    Wow!!! Well done. What a great find and a great prep.
  5. Here’s a Ceratopsian vert from Drumheller Valley, Horseshoe Canyon Formation of Alberta, Canada.
  6. Looking for assistance in Calvert Cliffs

    Well after my dads surgery went south and he had to have his leg amputated I’d rather not temp the issue lol.
  7. Looking for assistance in Calvert Cliffs

    At least it happened at work so I’m still getting paid. And that’s True Kane! Not peak fossil collecting or metal detecting season. Hoping to be healed before then
  8. Large Track

    Formation: Portland (Connecticut Valley Region) Location: South Hadley, Massachusetts
  9. Looking for assistance in Calvert Cliffs

    Ouch! Sorry to hear/see that, Rob. Give yourself all the time you can to mend. The only silver lining is that it is winter, so if you were going to be placed on the DL, best that it didn't happen in high collecting season in our part of the world!
  10. Plant fossil

    Ok, That narrows things down a bit. Below is a geologic map of the area from Google Earth and the USGS. The light blue/teal colored rocks are Oligocene Santa Fe Group. The Dark Purple near the top is Paleogene aged units. The greeninsh tan areas are Chinle group which is Triassic aged. And the red areas are Morrison formation which is Jurassic in age. Does the area you found that rock in fall into one of those rock units?
  11. Sharktooth Hill Tooth

    Your specimen, especially the wear pattern on the enamel, actually reminds me of a cone from a Desmostylus tooth. I've seen some really small baby/juvenile teeth. The below picture is from TFF @32fordboy. Marco Sr.
  12. How do you choose?

    I tend to lean towards the more detailed specimens (my preference). Unless they're too small to see the details with a naked eye, then I tend to gravitate towards the best looking larger fossil.
  13. How do you choose?

    Agreed 100%
  14. How do you choose?

    I need more room, but for some reason they won't let me build onto my apartment. Frankly for me, it would be the the one that appeals to you the most. Kind of like "Goldilocks" maybe not the biggest or smallest, but the one that is " just right".

    Very nice prep work and awesome find, John! Thanks for posting it!
  17. Amazing Arizona Adventure II

    Starting with a 29% solution, I dilute it to a 10-20% solution. If the fossil is fragile, I use a lower concentration of acid to prevent concussion fracturing from the bubbles forming and popping. The biggest problem with the higher concentration solutions is from overtopping the container from the vigorous bubbles and organic slime from the limestone.
  18. Amazing Arizona Adventure II

    Very cool looking Crinoids. Some of the detail is very nice too.
  19. Encrusted With Mystery: Can Anyone Tell Me What The Pattern Is?

    algal thalli are very prone to disaggregation and micritization. The encrusting/epilithic habit in algae is(I think)predominatly rhodophycean(corallinean)
  20. How do you choose?

    Quality always trumps size is my approach
  21. Diane has send me a very interesting link: Wooster’s Fossil of the Week: A brachiopod with a heavy burden (Upper Ordovician of southeastern Indiana) It's a very great & reary specimen ("the bryozoan had encrusted a living brachiopod, and the brachiopod stayed alive, keeping the essential commissure (the gap between the valves) open for feeding.") Ordovic Devon Perm These "life assemblages" confirm that bryozoan can cross commissure when brachiopods are alive ("keeping the essential commissure (the gap between the valves) open for feeding")! it's really a very rary specimen!!! @Mediospirifer @Shamalama @Al Tahan @Fossildude19
  22. How do you choose?

    I personally prefer my fossils to have better details. I really don't buy fossils unless I can get a bargain on them. However, I do look at them frequently, and enjoy having highly detailed specimens over larger items. Not only is this personal preference, but also depends on how much room you have to display/store them.
  23. Large Track

    This is what I am seeing: At best, this is a poor partial print. At worst, a suggestive shape, enhanced by the paint.

  25. Amazing Arizona Adventure II

    How much do you dilute the acid? HCL is pretty harsh compared to acetic or formic acid, unless it is diluted a lot. Don
