I've just finished prepping this juvenile plesiosaur bone cluster with nine separate bones in it. It took about three weeks of work which was about a week of manual prep and two weeks of acid prep. It was a very tricky prep as the rock was full of cracks which the acid kept getting into and there was a trace fossil on the back I wanted to keep. Its from the aristonectinae family of elasmosaurs and probably the third or fourth example from New Zealand. Full prep video is on my YouTube channel, link in my bio.
Im trying a new method to get some microfossils ready for a closer inspection. It was a real pain to get hold of some hydrogen peroxide as there seems to be a shortage of it at the moment. The peroxide is hopefully going to remove the bit of calcite and siltstone still covering the forams. I'll do a video of the process for anyone interested in the process. Swipe to see an example of one of the forams, its about 1mm long.
I found another section of what I suspect is part of a cetacean skull. I have another very similar concretion which had a section of squamosal and an earbone in it, hopefully this one does too! Some very dense bone in there for sure. I'm not sure if that is a bit of earbone peeking out in the one photo. I'll have to go back as there are 3 other pieces of it as well ๐
I stopped at one of the local rivers on the way home and found a couple of fossils and a bit of jasper looking rock. First photo is some petrified wood with very nice grain visible. Second photo is some jasper I'll cut. Third photo is a bit of worn Waiparaconus thats tumbled down the river. There is still a debate whether this is a barnacle.
Edit: looks like it is Megascyliorhinus cooperi I saw this tiny bit of shininess in the cliff today and was hoping it would be a shark tooth. I carefully removed a circular section of siltstone after putting some consolidant (B72 paraloid) on it. Luckily I did as it had a nasty crack running through the one side of the root. Back home this evening I removed the siltstone with a toothpick and water and exposed a beautiful shark tooth! Have a look at under 6x magnification, its a beauty! The tip is see through and still sharp as the day it got lost. It's around 12-million-years-old, mid-Miocene from New Zealand. Let me know if you recognize the species!
Update: might be something like a Protosphyraena rostrum ๐๐ A quick fossil prep of a bit of Cretaceous bone this evening. I thought it was a bit of rib at first but the taper doesn't look quite right ๐ค Let me know if you recognize it. The cross section shows some really thick walls as well.
A beautiful fossil I found earlier today hiding amongst some rocks ๐ It's a nautiloid, unsure of the exact species but the chambers are beautifully exposed. The body of the nautiloid occupies the last chamber, the living chamber. Often I find the chambers of the fossil ones I find are filled with calcite crystals. Swipe to see it's living relative, the nautilus. #
Im just about ready to give my air abrasion setup a go! Just a bit of plumbing still to do and then it's ready to rock. I've gone with the Vaniman Problast and I'm going to start with the softest media until I find something that works well for the fossils we find here. Between the air scribe, acid and air abrasion I should be able to tackle some of the trickier fossils ๐ค First up is this bone cluster that just won't play nicely with the acid.
