My hypothesis for the abundance of crab fossils is that turbidity currents may have buried large numbers of crabs during periodic gatherings and migrations for spawning or molting. These migrations can include millions of crabs, and if a landslide happens during one, that's a perfect recipe for rapid burial and fossilization.
Just discovered your channel after searching how to identify fossils on the beach hidden in rock. I collected about 4 or 5 suspected concretions today and am super excited to learn how to expose what might be inside them. Looking forward to diving deeper into your channel. Good stuff, man!
That was very informative. There seem to be varying degrees of hardness for the matrix, even within one formation. The process leaves plenty of room for variations on the theme, it's engaging to imagine what was going on at the coast to exact these results over time. What an enormous amount of work, between the 3D model animation and the actual tank, that went into creating this video. So well done, thanks for sharing. Cheers!
Thanks for the awesome video, sir! It’s really cool to see a visual recreation of this phenomenon. Hope you and your loved ones are staying safe and well over there!
Question: Do you actualy experience differences in the sediments surrounding the crabs giving you the ability to see from where in the turbidite the crab was deposited? Turbidity currents leave a recognizable structure of fining upwards sequences with sedimentary features, can these be seen in the concretions? I actually loved this short video it is a good way of explaining something quite complex in an easy way.
I have seen definite turbidity deposits in some areas with varying layers of particle sizes. The crab concretions are also in definite layers but I can't say 100% that they were deposited in turbidity currents.
From Mamlambo videos most of the crabs he founds are in concretion on the beach. Some nodules may be found in Bouma sequence but the crab may be situated anywhere in it as it may be transported on long distance and in chaotic way (poor little crab :( )
Not Only do you master the Find, then Reveal So Well we get see such detail of these Fascinating Creatures, You've Just Reversed the process - well, maybe Leap Frogged Back in Time. Nicely done! *Thanks!* ... Next Rising from the 'Grave'; Pushed up and out, tossed and Rolled with tides to Rounded forms. I'm guessing. Oh yes, Leaving band of rock around Crab with each side exposed is Really Nice look! : }
Nice animation! I wonder how this works with other minerals, as fossils are also found in pyrite nodules. Another interesting fact is that concretions were thought to take hundreds of thousands to millions of years to form. However, they instead apparently grow at a very fast rate over just several months to several years.
Very informative thanks! I'm from newmexico and I would like to find some fossils but dont know where to start I needa research some near locations or something because this is awesome and interesting.. I cant stop binge watching fossil discoveries lol..nice content you got by the way and dope specimens!!
Wow, what a really neat recreation of the fossil forming event. You certainly went to a lot work and trouble to explaine it. Great information. Thanks for sharing your time and intellect in doing it. Keep the goodness coming. Be happy, safe and stay healthy 😷⚒
*VERY WELL DONE, MAESTRO;* thanks _SO MUCH_ for this informative video! Although I've had a basic idea of the mechanics of the nodule formation, seeing the chemistry really brought it all home to me. It's grand to be able to "hike along the rocky beaches with you," albeit only in this vicarious manner. Take care of yourself, & stay healthy, young man! 👍
Thank you so much for sharing the information, I was thinking and I have the same question how it's happened and you just made it so clear God bless you 🌹
Awesome! New subscriber. I’m fascinated by fossils. I’m amazed that crab fossils, in whole, can be found! I have no idea what to even look for when trying to find them. Concretions, I understand, but finding them and looking for one with something in it, is a whole other thing! 🤯. Thank you so much for sharing. This was super cool! Stay Crystal 💫 Mari.
Crabs hide by burying themselves in the substrate (sea bed). If they die buried in the substrate they are not scavenged because they are hidden. If they die unburied in the substrate or are otherwise attacked for food, they are subsequently predated and in pieces. However, many crabs you find disarticulated are the casts of shed carapace, legs and claws. Basically, these parts have fallen to pieces when cast off by the crab (or lobster) when it grows into its new shell. These parts are preserved intact because there is nothing to eat but shell, so they're not chewed up. The phosphate of the carapace of a dead crab attracts phosphate (that's bits of decomposed animal and excrement) in solution in the sea. This condenses around the dead crab parts forming a phosphatic nodule. I used to collect fossil crabs from the London Clay, Isle of Sheppey, Kent, UK. My entire collection crustaceans, fish, shark teeth, birds, crocodilians, snakes, etc., has been donated to the Lapworth Museum, University of Birmingham.
Very cool vid n demo. Been watching about old maps involving antartica where a poss land bridge was n how the area shows a disturbance of a break up. Possible australia/new zealand broke away from anartica before it became or while it became covered in ice. It was interesting. Makes me wonder even more with your vid demo. :) Edit to add: there is an active volcano in antartica, food for thought.
Hey mate i found a very small verison of this in aus along time ago, i lost the fossil now i have been hooked trying to find one similar to mine ,mine was very small 1 inch , is this for sale ny any chance ? or any like it ? if possible please send a contact and will get back asap cheers mate
At first I thought you were doing an early Easter episode with a crab bursting out of an egg.😁🤪 With that being said you just have to ask yourself what comes first? The crab or the egg? Interesting theory. Very plausible.
Just viewed one of your videos on a channel called newsflare. They claim that they are exclusively managing the licence for that video. Does this infringe your copyright. As the original owner of the material.
Maybe your mistaken- I found you run an electric current with a crab in mud-(ocean floor)- the settlements will from around an concrete or fossilize the crab-fish,jelly-coral-marine-mammal…forest,or dare I say it-dinosaurs!!! 😮

Yep. Thats exactly what happened.

My pleasure!! It was fun trying to visualise how it all fitted together, it was a really good paper that I used as a reference.
Took the words right out of my mouth. But only said better. 👍❤️
The recreational were really interesting! They added a lot of impact to the story.
Thanks so much!!! Stoked you liked it. It really helped me as well
Great explanation
Thanks Moto!!

Thanks mate! We're all doing well thanks :)
Wow! The first really clear explanation i saw about how concretions/nodules are formed! Now i understand!Thanks a lot!👍
Fascinating explanation. I'm glad I found this channel.
Glad you enjoyed it!!
you are "rocken"those crabs. Loved the presentation
Thanks so much mate!!
I am afraid I will not be joining you this morning…. Your premier starts at 2am Colorado, U.S.A. Time. But I will watch in the morning!
All good Mindy! Sorry it's so late for you, I'll have to do some earlier ones next time
Very informative, great animation!
Thanks! I'm still learning my way around blender :)

@@MamlamboFossils ash too, such as volcanic?
Great question
@@robzombieshot i don't know if I would be able to recognize ash in the sediment

Nice work. I have been wondering that ever since I started watching your channel.
I found this very interesting. I knew how fossils formed but not how the concretions formed. Thanks for sharing.
Glad you enjoyed it!!
Fantastic lesson ! I've wondered about this process !
Great information and explanation even at 70 still learning and absorbing new information thank you
That was really interesting, I'd like to see more informative vlogs like that
Great show!

Great video - amazing how a simple creature can bear witness to, and ultimately, tell a story about one particular day on Earth so many millennia ago.
It is! If only it could tell me where the meg teeth are!
Very interesting. Beautiful crab. Love your smile too. The world is so sad right now, thank you for great videos
My pleasure!!
WOW, just wow. A really great video. 👍
Thanks Tracey!!
Neat experiment! The science behind the fossilization is very interesting!
Thank you! Cheers!
Wow! Well that answered questions that I had. Thank 😊 for the education. I always ♥ watching your show.
My pleasure, I got all the info from the paper I referenced in the details.
Nicely done.
Thanks mate!!
Thanks for explaining this.
This was awsome thank you for helping to understand the process.❤
Amazing video!

Yes definitely rapid burial, air exclusion being one of the major factors for its detailed preservation!
That does make sense!
Cool way to expose display this little guy Great explanation 👍
My pleasure!!
Thankyou. More like this please
I'll try my best!

Cool, thank you!
So from the time of being buried, to the time a solid stone is formed and the fatty acid is used up, how long does that process take?
I've read that it can happen in months in some cases but decades rather than thousands of years I think
Hello! That's a great video. Who made the animatión???? I would like to use It
I made it, feel free to use it, just link back to my channel
Thank you for that. Have asked a couple of times how a concretion forms. Now I know. 👍
My pleasure, I got all the info from that paper I linked to in the description.

Nice, can you reproduce it in a real enviorement without 3D thanks grat job

Hi Julian, I don't sell any fossils but you can get the 3D model on my website and print your own!
It's like the "Pompeii" of the crabs
Great description!!

Hahaha it does look like an egg! 😃
Thank you!!!🧡👊🏻🇨🇦
My pleasure!!
Thanks very much for the explanation i was wondering why does that ball sphere shaping around them.,and now I know so again thank you! Godspeed!
My pleasure!!
Nice! Thanks!... And now I know.
My pleasure!
Thanks you.. now I know how that happens!!! ☆☆☆☆☆
Thank you very interesting thanks for sharing five stars
My pleasure!!
Where can these be found? Do all concretions have something inside? Thanks
no, only in some areas - you will have to do some googling
Too blinking good, you!
I think what really happened is krabby and geodude decided to make a baby and this is what came out
I dig :)
Hhahaahaha awesome! I got a call saying there is a package for me at the post office! I'll go check it tomorrow :)
@@MamlamboFossils Awesome! I was just thinking about that today. Enjoy!!

Yeah, they have permission to use it 😀
How would it be round if its under pressure ? It's in its egg .
So it's basically naturally occurring hydraulic cement?
So fatty acids caused the rock, so you are an expert in fatty acid rocks
Noah’s flood. Very large flows.
Poor crabs.
Yeah, poor things had quite an exciting life!

Rapid burial by water….when all the sediment settled during the flood it encased the crab
