That is awesome! Glad he likes it, now he can see where it was found! It's a really nice example of the Tumidocarcinus crabs, and you don't even have to do any prep work on it 😄
Hiya Pammy! Ahhh, I'm so glad my videos cheer you up, it really is so cool being able to share my adventures with everyone! Thanks so much for watching and commenting, keep well!
I’ve been watching your videos now for a couple of weeks. I like to watch them when I eat breakfast.I’m always excited to see what you’re going to find next and I absolutely love when you prep things and give me a look into what is inside of the Rocks you find. Watching your videos is a nice break from the crazy of this world. When you give shots of the ocean I like to pretend that I’m sitting there enjoying the waves in the sand myself. When you pulled out that crab I gasped because of how amazing that claw looked and I found it very kind that you gave it to somebody else. Thanks for the break from life for just a bit.
I often stop looking down at the ground for fossils and just take everything in, being alone on an amazing beach with the sound of the waves is such a good way to blow away all the cobwebs. I'm glad you are enjoying the videos 😄 The claw on that crab was soooo pretty! I loved it and I'm sure the other fossil hunter loves it as much! My first crab was not nearly as pretty as that one 😄
Love the enthusiasm you put in, as one of the comments said it`s just like being there, except we don`t have to do the Hill. always looking forward to your next video.
That might be a while still! Still trying to get my head around the acid prepping 😄 I've carried on prepping that bone cluster and one of the bits of bone looks very interesting - I'll do an update on it soon. Keep well!
Great video for me to start the day on, hahaha. Nice finds, it amazes me how your fossil hunts excite me it is almost as if I'm hunting myself. The prep parts are also very nice , especially when using different techniques. Good luck on your next hunt.
Thanks Marc! I'm really glad the fossil hunting videos are exciting 😄 I feel the same when I watch other people fossil hunting - it really makes me want to go out and find something!
It is beautiful over there ! Thank you for the adventure and sharing how you some of your exposing your finds ! Take care , stay safe and healthy there in New Zealand ! Still doing well here in Kansas ! I have been working on my driveway getting ready for putting rock on it ! Time consuming as it is 1/10 of a mile long and I'm making a little wider than what it was when I moved here 9 years ago ! Looking forward to your next video !
Thanks Steve! Glad you're doing well that side of the world. Hopefully the rocks you put down comes from an area with some fossils, then you do fossil hunting right outside your front door 😄
Thanks for the new vid, you’re a good man to share your finds with the youngsters. That’s how new scientists are made. That fossil with the claws showing was cool. We don’t have anything like that in Utah, but we do have some great dinosaur quarries.
Hi from the UK, love your videos and your happy attitude during these difficult times would love to go on a hunt with you. I always have a wander around the jurrasic coast in Devon and have found a fex bits of bone nothing identifiable though.my parents live near the oldest part triassic not many fossils but I found a huge slab of fossilized sea bed, and you can sea the sa d dune outlines from when the uk was south of the equator again great videos.
some nice finds especially the 3 associated verts, man getting to prep that concretion will take along time but it will be worth it ten times over :0) with the acid prep does it soften the concretion to and make it easier to use the scribe, i've never used acid prep before so just thought id ask :0) super vid and you'll have to get a motorized red trolley as that would help you so much getting up the hills and with bigger loads too :0) have a super day mate and looing forward to the next one :0)
Hiya Robert! The concretion does get a bit softer in the acid, but only the top 1mm or so. I'm using sulfamic acid which is a bit stronger than acetic acid (vinegar) and reacts for longer. I really do need a motorized sled or trolley. I have two big fossils I haven't been able to recover yet because it is just too heavy!
@@MamlamboFossils hi mate, i know nothing about the acid prep but at least is make it a little bit easy, not much but a little :0) it sounds mad but if you had a sled maybe you could pull the bigger ones nearer to your car and maybe a friend help you with that :0) have a super duper day and i'm hoping to get a shark tooth hunt in at the weekend if the weather is good so sunday i may be able to send some pix :0)
@@robertmartyr2041 Hi Robert, hope you're doing well! I haven't seen you around in a while and thought I would check you're okay? Hope you're getting some shark teeth!
@@MamlamboFossils hi mate, we are good and i have still been watching your vids and loved the great white you had in the last vid, it's a beauty :0) can't do any fossil hunting as we are on lockdown for the 3rd time in a year and i think i only did 4 fossil hunts in the whole of last year, i got some shark teeth but nothing to write home about unfortunately. hopefully this year will be better for all of us :0) have a good evening or morning :0)
Wow that is quite the find! Little red wagon has another appearance! Hmm wonder if a small battery driven motor with chain to axle would be enough of a power assist to help up in lines when you're loaded up? Never mind me just imagining....
I've wondered the same thing, maybe an electric bike motor? It doesn't have to be fast at all, just chugging along will help. On the other hand, it is really good exercise 😄
Yet another wonderful trip(s) - good luck with that vertebra - thats going to be a lot of work but man its going to look great! Looking at the vid of you dragging the red wagon up the hill, I cant help but wonder if it would be easier to use a rope & belt - as you had the front wheels off the ground a bit! My scribe finally arrived - man its loud but seems to use less air. If we could have got them for that first dodgy price I'd happily buy another couple.
Yeah, it really is a nice little scribe, very powerful but noisy like you say! Yeah, I'm thinking a longer rope will work for that hill, it's fine on the sand but the hill is so steep that it keeps standing up on me.
You're lucky having access to such a rich fossil site. Here there's nothing on the surface. We have some of the most famous finds in the world, all from mining and university digs however. Out of reach for an amateur. You're crabs are awesome. Would love to be able to just go out and look for them.
I love history so much. Fossils and artifacts are my favourite. I am currently studying history in university but we only study about theories and happenings in the past. We studied archeology only for 1 semester and I wish I could study these kind of things more😩
I'm curious what acid are you using for prepping? I use 5-10% acetic acid. Bone is usually quite resistant to it and I have had good success in preparing vertebrates this way. I typically leave overnight in acid and wash off in the morning. Depending on how much is exposed I either gently immerse in water and waft off loosened mud or if a lot is exposed I soak for a couple of days in 2 or 3 changes of water before drying out and consolidating.I don't use paraloid, instead I make up a thick stock solution of polystyrene foam in acetone. I save used coffee cups and polystyrene packaging or if I need a lot I buy a packet of pellets used to stuff bean bags. I thin down the stock solution as needed with more acetone.If any fragile bits are projecting or any fractures are apparent I brace them by gluing matchsticks and toothpicks with polystyrene model cement. I have used similar techniques on fragile partly silicified fossil shells but can etch these with dilute HCl.
Hi Gary! Sorry for the delay in responding. I use a 5% sulfamic acid solution, it's a bit stronger than acetic and reacts for longer.

Cool stuff, wish there was some of that round Auckland. Have some shell/rock from Kiritehere beach near Kawhia but nothing as interesting as your finds
I think there are some amazing fossils sites on the North Island, maybe further south from you. The volcanic areas aren't the best for fossils but the Coromandel has some epic petrified wood from what I hear!
@@MamlamboFossils Thanks, just looked at a video of Port Waikato about an hour south someone finding belemnites, Will have a look for Coromandel hunting ops now
Very nice..I see you lift that very large triple vert. And had a flash back...carried out three ton a amazing agate from a certain water shed....had to grunt load my back harness...one agot was so big and massively heavy,extremely dense...you know what I mean ..pulled me on my back feet flailing in the air..I was only 125 lb at the time...the agot I carried out ranged. from 75 lb and under..the 200 lb one took me 16 hours to pull on a grain shovel clearing rocks on the river shore..then I met my 7 foot bank to climb...I made increment steps grunted balanced and dug...when I got it up on the road..I knew I was in trouble ...how was I going to get it into the truck box..when the tail gate was open ,I had a lift of a good 3 feet...I started dragging splintered trees log and slowly made a tripod and rocked the massive round agot up until I could roll it into the truck..FUNNY the back of the truck literally dropped..when I drove home out of the bush my headlines were above the tree line. I think that agot May have been heavier than I thought...anyway, when I got home I rolled it off the back outside of my fence...at first I was worried it would be stolen...but when I realized it sunk half it’s volume in the dirt...I felt safe!
Oh man, that sounds like some amazing agates you found! I can appreciate the effort you put it, you can't just leave something that good 😄 I've done the same thing, having to carve steps out of an embankment. It's time like that you wish you had a friend with a helicopter 😄
Bro I love you so much, you're the most wholesome guy, and you've got a really awesome skill that I've love to have. Love your stuff so much, so excited every time I see your videos in my inbox. Keep it up man, love it!
@@MamlamboFossils As I understand the subject; Some of the water worn, rounded stones you examine while looking for fossils have a much flatter surface on one side. In this respect they are essentially analogous to primitive grindstones employed by stone age cultures such as Australian Aborigines. A few of the stones I have seen you examine feature characteristic scoring as well or instead as though the teeth of an excavator bucket had dragged over them. Collectively this can be evidence of the stones having been imbedded in ice at the bottom of a glacier. For the information of anybody who may not know, the ice of which Glaciers are comprised slowly flows downhill over inclined terrain. By this means the aforementioned stones are slowly dragged along the surface of whatever terrain the glacier in question may pass across resulting in the stones eventually becoming flattened on one side. Stones can of course be worn in similar ways by other erosive effects. When they are present at the numbers apparent in your presentations however such characteristic erosion is more highly likely to be the result of glacial action than anything else. The fine, gritty consistency of the talus in which the aggregates occur is also evidence of the slow but steady erosive effect of a glacier as it abraded terrain. Even at Antarctic latitudes Glaciers often if not normally have a stream of liquid water flowing under their base. Stones that have been worn down unevenly by the grinding action of moving ice often eventually fall out of the ice in which they were imbedded. The stones can then become water worn in the aforementioned stream which is also laden with fine abrasive material resulting from grinding action and is also deposited by the glacier. The flattened stones are characteristic evidence of glaciers both modern and ancient and can usually be found at locations where they existed or exist. There is a place on the coast near Adelaide in South Australia called Merino Rocks where an ancient glacier once flowed into the sea and many such distinctive rocks occur there.
What causes the concretions in your area? I find few here on the East Coast, U.S.. I have two almost totally round ed ones found in creeks in North Carolina but am afraid to open them. They weigh approximately 5 pounds a piece. ☺️
Not a dumb question at all, I had the same question. Yes, they are extinct. Some of the crabs I find are still around today, like the Pie Crust crab Metacarcinus novaezelandiae
It's probably a slightly different process depending on locality. These fossils were in a muddy area that might have been covered by some natural event. The decomposition then leaked into the mud forming a natural cement which was harder than the clay cliff which is why they erode out like that.
@@MamlamboFossils YEEE! Not gonna lie, today was a pretty rough day. Nearly ended it on a bad note. But, luckily I stayed up two minutes longer than planned and saw you posted. Really helped turn my day around! I know you're just playing around with acid prepping for now, but would you mind giving an in-depth break down of how it's done one day? I'm always a big fan of educational/instructional videos :) Keep up the great work, and happy hunting! Looking forward to the next video, already!
@@Anubis30224 I'll do a more in depth video at some point. I'm waiting for a PH meter so I can get some proper stats going 😁 glad I could help make the day a bit better. Keep safe!

Go to the beach and see a guy who's talking to the rocks. 😃
Hahaha, I haven't seen many people around but I'm sure I do look a bit strange out there frowning at the rocks 😄

That group of vertebrae fossils will be interesting to see when it's done. It looks like there is more than just the vertebrae there.
Yeah, I agree! There is quite a bit happening over in that concretion. It's going to be a very big project!

It is interesting to see evidence for glacial action as well as normal liquid water erosion on many of the stones visible.
I'm not well versed on glacial damage, whereabouts on the video do you see it?

At this location is seems to be the decomposition process that causes the mud to harden in a cement around the fossil.
Mamlambo , thanks! A perfect time capsule for the fossils you discover, isn't it? ☺️
👏👏👏👏👏
Might be a dumb question but are tumarocarcinus extinct?
Not a dumb question at all, I had the same question. Yes, they are extinct. Some of the crabs I find are still around today, like the Pie Crust crab Metacarcinus novaezelandiae
How does the rock harden with him in there? Is it compression over time with the correct amount of moisture?
It's probably a slightly different process depending on locality. These fossils were in a muddy area that might have been covered by some natural event. The decomposition then leaked into the mud forming a natural cement which was harder than the clay cliff which is why they erode out like that.
@@MamlamboFossils very nice,,, TY
What acid did you used?
Sulphamic (sulfamic) acid but acetic acid is safer
Did you ever prep the big vertebrae rock?
Not yet! It's still in the queue and not very high priority
Is that acetic acid?
You can use acetic. I use sulphamic which is very similar
i would love to have a small crab concretion. How do you feel about sending one to the US?
I can't send fossils out of NZ without a permit for each individual fossil :)

Not gonna lie, today was a pretty rough day. Nearly ended it on a bad note. But, luckily I stayed up two minutes longer than planned and saw you posted. Really helped turn my day around!
I know you're just playing around with acid prepping for now, but would you mind giving an in-depth break down of how it's done one day? I'm always a big fan of educational/instructional videos :)
Keep up the great work, and happy hunting! Looking forward to the next video, already!
@@Anubis30224 I'll do a more in depth video at some point. I'm waiting for a PH meter so I can get some proper stats going 😁 glad I could help make the day a bit better. Keep safe!
You need to design a motorized wagon
That one rock looks like skin
Yeah it does! Some of the crab shells do as well
Third!!!
😄
It's a rock. By what magic do you know that there's a fossil in there?
I look for any change in the surface, colour or texture. Your eyes get trained very quickly 😁
Fantastic find!!! Hope to see that spine after it is prepped and whatever is exposed from the acid bath.
