    The important question is: how do you determine which side is "up" when prepping the fossil :D

      The shape of the leg cross-section. The top is the side with the most concavity. .

      From what ive seen usually the leg rings on the sides indicate top or bottom. They usually are in the bottom half.

      Great question - the leg shape does help as modelleg mentioned, I do still get it wrong from time to time. On the big crab I actually started on the wrong side first :) Sometimes the legs have been flattened which makes it hard to figure out which side is up. The shape of the concretion also helps, usually the are a bit flatter on the top side of the crab.

    I think the crabs fossilizing is unlikely to all be the result of tsunami, there is just too many of them. A more likely scenario to me is that crabs burrowed deeply into mud banks (look at Australian mudcrabs for comparison) and were then killed by something like a storm event cutting them off from the estuary, and drying out and suffocating while buried.

    • @MamlamboFossils
      @MamlamboFossils  3 ปีที่แล้ว +27

      The crabs in holes is an interesting theory. This location was 300m deep so I dont think it would have dried up. Tsunami or earthquakes couod cause turbidity currents. We're probably talking about thousands of events over millions of years

      There's too many of them? LOL. Have you ever seen how many crabs are walking in the ocean floor? Huge casts, of thousands of crabs, all walking along the floor. One turbidity event could bury 10k crabs at once.

    This is a great video. Your explanations for determining signs of fossils within a silt matrix was very insightful and inspiring.
    Based on your hypothesis for the hydrolysis of this crab, here’s my best understanding of the deconstruction of the crab’s chemical composition (as it’s been exposed to the Ca2+ ions in the water). Note, there are innumerable ions in sea water, so this chemical reaction is VERY simplified.
    HCO3-(aq) + H2O(l) ↔ CaCO3(s) + H3O+(aq)
    Bicarbonate (carbonic acid) in an aqueous solution (aqueous just means that a chemical can dissolve in water) reacts with liquid water to form a concretion of solid calcium carbonate and hydronium, which is a weak acid that dissolves easily in water.
    Crabs and other hard-bodied organisms such as snails, ammonites, mollusks, etc. tend to be very common in the fossil record, as the amount of calcite in their hard outer-shells can easily undergo mineralization fossilization. This is where an organic substance's chemical compositions can react to ions specifically in water to form very tough and hard biproducts, which tend to last the test of time despite the relentless weathering of an ocean/beach environment. Essentially, their chemical compositions are gradually replaced by harder solids, forming a "stone" versions of the once living organism.

    @mamlambo Fossils....have you ever considered first making a cast of the concretion then revealing one half of a crab, then cast that side in acrylic then reveal the other side and do the same? this way you could reveal the entire crab and have it encased in an acrylic "concretion" so you can maintain the original shape of the concretion but the clear acrylic would give us an "x-ray" view of how it sat in situ?

      If you live near a university, you should get in contact with their geology or earth sciences department. When I was at the University of Alberta they had a volunteer program where people could help the university paleontologists prep fossil specimens. You didn't even have to be a student. It's a great way to get experience while working with an expert. I'm sure my old uni isn't the only one that does this. It's also a good idea to talk to them before starting so you can learn about ethical collecting methods and about any local laws around fossil collecting. To go back to my previous example, it's actually illegal to collect and keep fossils as a private citizen or visitor in Alberta. Different places have different laws so you gotta check where you are!

    Very interesting theory. I would find it to be a lot of CaCO3 just from the C from the crab. Seems like it's too much (just by my gut feeling :) ). We have these CaCO3 rocks on the shores of England, so I wonder if it could be a combination of your idea and deposits of shell material. Super interesting!

    I was told that the crab's hibernate during winter by burrowing in the mud by creating a small oval chamber . Sometimes they die during this time and minerals fill in around them and turn the chamber into rock over time. I don't know if that's true but it sounded like a reasonable explanation at the time.

      Fossils aren't random, if there's a spot with one fossil, there will often be more hiding nearby! The easiest way to figure out if it's a good fossil spot is to look at local fossil enthusiast groups and see if they recommend that spot. If so, find out what kinds of fossils are usually found there and how to identify them. Different locations will have different kinds depending on what time periods the rocks come from. Good luck!

    Hey man I'd love to hunt for fossils, I live near the great lakes on the Wisconsin side, is there anything I could find on the beaches there? There are some very large bluffs and big storms collapse them every once and awhile, also the great lakes used to be a large salt water sea/ ocean until some kind of major event where all the salt was pulled out, don't ask me how but that what I've heard, anyway I've seen rocks with little shells in them before but I'd love to learn to find some sort of cool fossil

  • @valiantwarrior4517
    @valiantwarrior4517 2 ปีที่แล้ว +1

    That makes a lot of sense about the conception formation. I’ve been trying to think of ways it would happen just through straightforward sedimentation and erosion, but it didn’t quite fit, because they seem to come right out of the cliff like that. My mind was thinking something must happen to change the matrix around the crab and make it more dense. The way the shape fits the crab(etc) does strongly imply that it is having a direct effect on the formation. And the same seems to happen with other similar things like nautiloids, ammonites, clams, etc. All things that would have a lot of carbon in the shell or exoskeleton.
    Thank you so much for sharing your theories!

    One thing you haven't picked up on. Is crabs molt every year, when they are large. For the first 4 years a crab can molt upto 20 times. Just sharks teeth are the most common fossil to find, because they lose teeth every time they eat.
