Well I started my next project tonight, and compared to the last one, this one is so much fun (so far ). The rock is softer and it also peels off the shell beautifully. Things are going to get a bit more complicated I can see already as there is a thick layer of powdery calcite around the edges. I originally thought it was shell and I’d stripped off the shell the whole time But I checked with the scope and it’s calcite. Some before pictures. The concretion is 24 cm (9.5 inches) wide. The claws were already exposed like this, I found it wedged in between 2 rocks facing me like this! The big claw exposed section is 8 cm (3 inches) long, so the big claw will be at least 16 cm (6 inches long)!

The lockdown has given me some time to go through some of my finds from the last year. I had another closer look at this fossil that I found at a Cretaceous marine site here in New Zealand. It almost looks like it could be a hollow bone? Has anyone got any idea what it could be?

Overnight fossil hunt in New Zealand - Doctor Mud and Mamlambo's adventure
mamlambo posted a topic in Fossil Hunting Trips
@Doctor Mud and I managed to get away for an overnight hike / fossil hunt we have been talking about for ages! We set off with high hopes around 11am from near Motunau Beach in New Zealand and within 2min,I found a beautiful crab fossil and a new species for me, an Actinocarcinus sp. A little further into the hike I noticed some shiny flecks in the cliff which turned out to be some cookie cutter looking shark teeth, probably Miocene era. This was really exciting for me as I don't often find shark teeth here where I am. It was an incredibly hot day, somewhat cooler than it should be because of all the smoke from the Australian bush fires which gave everything a rather strange tint. The first few hours were quite easy as it was all sand, but the going got really tough once we hit the jagged boulders that make up most of the coast in North Canterbury. We spent the new 5 or 6 hours clambering over them, exploring little coves full of cobble stones every few hundred meters or so. There was no shortage of cetacean bone and towards the end of the first day I found my first whale ear bones! I was over the moon with this find, I've been wanting to find some for ages. After a looooong day of hiking, we made camp just before 10pm, scoffed down some sausages and tried to get some sleep. We didn't quite get to the spot we intended to, so we had to make do as best we could which for me meant a night on some cobblestones The next morning we got up bright and early, a bit rough around the edges and headed back. Just after breakfast, we stopped and rescued a trapped sheep which seems to have been good for our karma because Doctor Mud made an amazing find later that day, I will let him share that himself. We got back to our car around 3pm and headed for the nearest coffee shop to feed the caffeine craving - neither of us had brought coffee along! It was a great hike and we saw some beautiful places Here is the video of day 1:

Hey there! I'm back again, and again I'm on another continent I moved to New Zealand at the beginning of the year, and in between the incredible fishing and birding I forced myself to head out to Glen Afric (2 hour drive) for a stab at some crabs. The day started out with a couple belemnites, quite long and skinny. The concretions were various shades of khaki to black, some of them still more clay than rock. There were various shells encrusted in them. I kept my eyes peeled for a 'crab' shaped concretion, however this was easier said than done. After a full lap (about 400m) I was nearly back where I started when I picked up a rock, turned it over and holy moly it had legs! Please tell me they're crab legs and not belemnites trolling me haha!! If it's a crab, would an air scribe be safe in the hands of an amateur? Anyway I had to go, but I'll be back!

My family and I have gone on a trip for the holidays so when we recently decided to take a trip down to Glen Afric again, we quickly realized we were no longer used to the hill that leads down to the beach. Luckily it was worth it and as always we found a few fossils that I have yet to learn about. Fossil number 1 Fossil number 2 I think this one could be a whale bone. I'm just wondering what part it could be Fossil number 2 Fossil number 3 As for the last fossil, I was wondering if this could be coprolite?

I braved the 30 degree Celsius heat to check out one of my local rivers, the Waipara, last weekend. I've had good luck there before with finding whale vertebrae and was lucky enough to find another one this time which makes 3 from a 1km stretch of river. I also managed to find the usual oyster shells and even a nice bit of petrified wood. Here is a video of the hunt:

I’ve been in New Zealand for over a month and spent a lot of time on the coast famous for the big Tumidocarcinus crab concretions. Unfortunately my trip was mainly to visit my father who was ill and he passed away while I was here. Time on the beach has been a good distraction and helps to start the healing process. You might be surprised that I usually have the beach to myself and the solitude and sounds, sites and smells of the coast are a comfort. In terms of fossils it was my best trip yet, but this came from lots and lots of walking, boulder hopping, and early starts. Sorry pictures are large files since I’m doing this from my phone. So spread out in many posts. Day 1, was exploring new sections of coast, clambering over rocks the size of a bus with razor sharp shells. Found some nice concretions, but they were empty

A couple of hours in on our fossil hunt at Glen Afric, I spotted another crab fossil! This had now been our 3rd crab of the day. We have not found a similar crab to this one. Any ideas or thoughts on why the colour is so strange?

I found this short-stemmed mushroom-looking thing on my favorite fossil beach in New Zealand. Any identification pointers would be much appreciated. It is very hard. The stem looks and feels agatized (or something like that) to me. I can't tell if the cap is really petrified or just really hard. A couple weeks later I found a similar mushroom-shaped thing on the same beach -- the caps are super similar, but the second one has a very long stem. I"m posting pictures of the long-stemmed one in a separate thread. Thanks for any thoughts.

I found this mushroom-shaped thing on a beach in New Zealand. I have no idea what it is; the stem is crazy long. It seems petrified. But apparently polypores can be super hard, so maybe that's what it is. But the stem seems much too long for a polypore. Or maybe it's a bolete? Still, the long-stem seems unlikely. I also found a short-stemmed (or broken-stemmed) similar item on the same beach. I posted pictures of it in a different fossil id post. Thank you for any pointers.

Hi everyone! I found what I think it a tooth or barb in the Waipara river in New Zealand. It was embedded in some limestone which I think is 35 - 45myo (Amuri Limestone perhaps?) but I could be incorrect on the age. I think the point broke off during extraction. Length: 15mm Thickness: Very thin - just under 1mm I made a video of me finding it here: https://youtu.be/337y9ZU4h1s?t=207 Thanks!

Hi everyone! I found this bone today, my first "proper" dinosaur bone I think! Am I right in thinking it's from a plesiosaur paddle bone? Thanks! Measurements are in cm. Location: Conway formation, New Zealand

How big do fossil crabs get? Some large Tumidos
Doctor Mud posted a topic in General Fossil Discussion
Having found my biggest crab yet, I was very curious about how big the Tumidocarcinus giganteus gets. It sure lives up to the species name giganteus! @Dave (POM) Allen has found a massive claw, the biggest I’ve seen. Could be from a huge crab too, but I’ve seen some really massive claws that are way out of proportion with the crab. I’ll have to dig out the photo from my computer when I’m home, but I have an amazing example of this. The Canterbury museum has the biggest specimen - complete crab I’ve seen There it is near some normal sized (but still much larger than Washington) crabs. I didn’t have any measurements on it, but when I visited Al Mannering to do some prep he had a replica and I asked if I could take some photos for reference. Check it out! Andrew Fear who is another regular Tumido collector has found this guy Don’t have any scale on it, but it is impressive! Love to see any other large examples, or even the other end of the spectrum like @RJB tiny Tim the Tumido

Hi Everyone, I was out at Glenafric in New Zealand with @Doctor Mud and found this concretion which might have a bone cluster in it. If anyone could ID it I would be really greatful!

Hi guys, Here's a large Miocene nautiloid (Aturia spp.) from the Miocene sediments of the north Canterbury coast in New Zealand. I saw it from a distance and thought I was seeing a weathered gastropod or turret shell. A shame that there is a bit missing but interesting to be able to see the chambers and siphuncular tube. I still plan to prep out what is there. It would be nice to find a complete one of this size one day! Its about 15 cm across. Red dashed line shows a possible outline of the complete shell. Another (dorsal) view showing the chambers and siphuncular tube.

Hey. So today on a whim I decided to give fossil hunting a go. Took my family to the beach at Glenafrik farm, about an hour north of Christchurch, New Zealand. About 30 minutes in I stumbled across this beauty (beginners luck huh). Now I’m wondering, what am I supposed to do to clean/preserve it? Also, my wife found what we think could potentially be a fossilised log? It is very heavy and to our untrained eyes, looks like a log with bark around it. It was quite different from all the other rocks in the area. What do you more knowledgeable guys and girls think? Again, any tips or thoughts on cleaning/identifying it?

Newly prepped Tumidocarcinus Giganteus crab, collected by myself
mamlambo posted a topic in Member Collections
I found a really good concretion a few months ago here in New Zealand and didn't want to try prep it myself as I am still very much a beginner. Luckily, @DLB was willing to help me out and did an amazing prep job - both sides! It's by far the best crab in my collection, and very well travelled after it's 24 000km (15 000mi) flight It measures 16cm (6.25") across. I made a video of me finding it, sending it off, and opening it which can be found here: https://www.youtube.com/watch?v=V4cqpVKsOO0 Thanks for the amazing prep job @DLB!

Found in Central Auckland, heavily volcanic area. Have found volcanic bombs, glass etc in same place. This looks like a root mass to me but I've never seen its like before. Trace petrification? Is that even a thing? Thanks in advance!

Fossil shark teeth hunt in New Zealand - 60myo formation
mamlambo posted a topic in Fossil Hunting Trips
I've always wanted to find some fossil shark teeth but never knew what to look for or where to go. After some research, I made a sieve and headed out to the hills of North Canterbury, New Zealand, to have a fossick around. The formation is about 60myo and is famous for the giant penguin and bird fossils that have been found in the vicinity. The first two hours were a bust as I sifted through some debris at likely looking sites, I did get a bit excited about a piece of bone I found which I think is from a rabbit on closer inspection. As I was filling the last bucket, I spotted a white dot in the cliff... my first shark tooth! It was about 1cm long, tiny but still a shark tooth! After switching to eyeballing instead of sifting, I found two more! One smaller and one larger shark tooth, the larger one showing a bit of damage but good details. All in all, I really enjoyed being out and actually finding a fossil shark tooth. If anyone can point me in the right direction to figure out what species it could be, please let me know! Or if you have some tips on finding shark teeth more efficiently, I'd love to hear about them. I made a 10min video of the day: https://www.youtube.com/watch?v=7kwqRWARWJk I've included some photos I took that day. Thanks for reading!
