Re: Rotifer for ID please

You don’t give a scale but is it possible that this is the skeletal remains of the head of a larvae, that looks like the remains of a mandible on the left and the overall shape and construction looks similar.

Re: Euendolithic tunnels in flakes on the beach.

This has been an awesome thread! I have a masters in geology and I didn't even question whether the pictured flakes were mica. It’s been an interesting project, I’ve learnt a fair bit about mica and oysters! There may be more than a few examples of this being mistaken for mica, take the photo on th...

Re: Diatoms DIC

I don't think it gets much better than that. Looks like you've put together a very nice set-up!

Re: Foram and Ostracod Shells

Thanks Rik.

I hoped that they would work well as stereo subjects, your pointers on the settings in Zerene helped a lot.

Re: Euendolithic tunnels in flakes on the beach.

Thanks Pau, I have a few photos here of the larger piece (1cm) that had a small area of outer shell attached but is well on the way to disintegration. Not only does this piece have some outer shell but it also has some of the prismatic calcite layer present. The beautiful colours that we see in the ...

Foram and Ostracod Shells

These photos were taken using external incident lighting and a 10x objective. The "shells" are all under a millimetre long. I have included a stereo pair of each image - all stacking and stereo was done in Zerene. Dave Foram foram_kdkdlsk.jpg Foram Stereo left_stereo_kdkdlsk.jpg Ostracod Shells ostr...

Re: Euendolithic tunnels in flakes on the beach.

Thanks Pau I put a few flakes on a glass dish and as a control I also put some shell fragments and some quartz sand grains. In 20% ethanoic acid the flakes and the shell fragments effervesced vigorously, the quartz sand grains didn’t so that does lend support to theory number 3. There’s a link here ...

Re: Euendolithic tunnels in flakes on the beach.

Thanks Pau,

I don’t have any HCl but I do have some 99.85% pure Ethanoic Acid (Glacial Acetic). Is this OK and what sort of concentration do you suggest?

Re: Euendolithic tunnels in phyllosilicate on the beach.

Thanks Ken. I'm on to theory No. 3 now, which is probably the best explanation of what I found.. I looked at quite a few samples of the small flakes and they nearly all showed the same phenomena, they looked just like mica...... layered, transparent when thin and very reflective and they could easil...
