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.

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

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.

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!

I was told that the crab's hibernate during winter by burrowing in the mud by creating a small oval chamber .

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 :) ).

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.

As a sedimentologist, you are partially right. But the carbon does not come only from the fossil. Most of the time, CaCO3 (formed from HCO3- and removed a H+ give you CO3 --, which is a perfect receptor for Ca++) need a core or a nodule to be fixed on. That is why, most of the time, there is fossile inside a concretion. If there is nothing inside, the former fossile may be dissolve or just nothing.

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!

Very interesting. Where did you find them? I'm in Canada on west coast, from the east coast. Lovely beach, but sharks yes. I heard there are great whites off Nova Scotia. We are getting fin sightings closer to the beach and never heard of that before!

"Turbidity currents" is such a fancy name on the diagram for "you're getting buried in mud and silt"

Well, it's a special way of getting buried in mud and silt 🤷

Do you work with a museum? How did you learn about the fossils and how to prepare them? Also what beach in Washington has fossil crabs?

I do work with some of our museums, I've just read up on fossils to help ID them. As for the prep, it's just been practice :) I'm not sure what place in Washington has them or even if it is a beach.

Seabed liquification within warm vents is the cause, the Crabs used the vents to bring food towards them and more oxygen is created, the vents are just dimples in the seabed, the crabs would sit in these little craters, and if a minor quake near that fault would occur, the sand and sediment would liquify creating a grey sludge, encapsulating the crab in the shape of the hole and the vent move the water over the top of the concretion creating a dome, due to the fact that half is within the hole and the other is formed above seabed, the concretion hardens with a kind of seam. the salt water ebbing and flowing causes the chemical composition to keep rearranging at the atomic level, which continues to harden the concretion, the Romans figured out what the ingredients were, and used it for the foundations of their buildings, with a few tweak's, there are some old Roman building that get covered by the tide daily, and you can't even mark it with a full swing of a sledgehammer, another amazing property of it compared to modern concretes is it never cracks while it dries, and there is shrinkage or expansion. Man used to study the natural world then mimick it, as it makes everything to perfection.

I love this explanation so much!! Thanks for a great comment, I'm going to do some further ready on it.

So with the sand and sediment liquefying, that must be the same with liquefaction that comes out the ground like with the Christchurch earthquake. So is the rock made of the same stuff as the liquefaction that comes out the ground?

Clearly, the filming of your exposing the crab was time lapsed, but how long did it actually take to end up with the finished product?

Australia.we had an inland sea.When itdied it got covered in silt on bottom of sea floor where the sea minerals entered the crabs body structure.Then it rolled around with the sea current.forming a round shape....

Man I love New Zealand lamb chops, only chops from New Zealand, lamb from Australia and the USA taste like crap. Awesome plant fossil, a pinecone is on my bucket list. Lastly, loved the footage at the end, those little birdies look like time travellers, poof dissappear from here, now I'm over here!

So the concretion "grows" using the carbon from the crab? Do you think the crabs were alive when buried? It's always intrigued me that most of your crab fossils are so complete. Love your channel mate, fascinating stuff.

Thanks Mark! I think there is a decent chance some of them were buried alive. If you imagine an mudslide going through a huge crab colony, some of them would have been alive for sure!
