Your picture is segment from a crinoind stem or arm. Still an echinoderm and still a nice picture.
It is not the calyx of a blastoid. They went extinct in the Permian, well before the formation of the Oxford clay which is Jurrasic, at the location you found this. It is not a calyx either as this would be much larger and cup shapped.
Hi, just though I'd chip in with something a little different. Two photos of a fridge magnet that I got when I was in Venice back in 2019, it's a Porcelain miniature mask, of those used during Masquerades in Italy. These were taken with it on it's side with the camera in landscape and then rotated as it was easier to set up. The black background was then cropped. they were taken with my Canon EOS 400D on A-DEP setting and using my Canon EF-S 35mm Macro lens, the first one was taken with daylight from the right hand side and the second one with the lens lights on full, and the daylight from the right, but as they have been rotated, the daylight is now coming from the bottom.
Regards Nick.
P.S. this fridge magnet is approximately 60mm x 60mm.
Jack, the moment I saw those front legs I had little doubt it was a mole cricket.
Back in Nicosia ’57-8, another chap in our camp had found one and was holding it gingerly between his finger and thumb inside a piece of rag. He claimed that its digging strength was so strong he could hardly stop it from moving.
The same chap had previously demonstrated his ‘ability’ to hand-feed flies to a praying mantis he kept as a pet. It chomped away as if eating a piece of watermelon, making no effort to escape.
Nick, I’d like to suggest that your fridge magnet would make a good subject for a stereo pair. Would you care to have a go?
Sitting on say BluTack, tilting it left to right a few degrees might be all that’s required.

Hi Sam, I've done a little experimenting today and it looks promising, but my technique needs a little refining and hopefully I be able to produce one. I'll show my technique when I have a satisfactory success.
Hi, OK following on from Sam Stones request for me to have a go at producing a stereo pair of the fridge magnet, I have now managed to do exactly that. I've made four images, one for parallel viewing and one for cross viewing, the other two are the same, but the distance between the pair, is slightly wider, I don't know if it makes any difference, but the wider ones produce a smaller third picture. The all work on my Android smart phone, in both free viewing and with a stereoscope. The first parallel one viewed with my stereoscope is really well defined and I am quite pleased at the result. The cross viewing ones when viewed with my stereoscope, look as if is sunken, as if you are looking at it on the side next to the face, but the eye holes seem to stand outward.
Hi, so, here's a brief description of my technique, first the camera was mounted onto my X/Y camera mount and that was then mounted onto my K & F Concept TM2515T1 in the manner shown below.
This was then set up in front of the fridge magnet in the next photo, with the closest part of the fridge magnet, directly over the centre of the tripod's rotating head where the horizontal bar passes through.
This was then adjusted to be square in all plains with the fridge magnet and the distance from the fridge magnet was adjusted to get it framed and at the same time the fridge magnet was adjusted up/down and side to side to get it central in the frame, which took a fair bit of tweaking. I then did what I though would be the angles that my eyes would be at while looking at the fridge magnet from the same distance as the camera was set at. I then used a simple protractor to swing the camera to the right, by lining up by eye, the horizontal bar.
The first photo was then taken with both my macro lens lights on the dim setting and the shutter was set to delay, so that any slight movement by pressing the shutter release didn't cause any camera shake. The camera was then swung to the left hand side and the above was repeated. The images were then downloaded and processed into the stereo pairs.
Going (viewing) cross-eyed, your efforts put a big smile on my face.
Then, just as I was about to send a congratulatory note, your follow-up post with technique description appeared and my smile turned into a grin.
As can be expected, out-of-register reflections from the glazing seem to cause the brain to switch between eyes producing a twinkling effect. This was discussed earlier, see Page 11 – 23th May 2020.
Hi MichaelG and Sam, thanks for your comments and I'm pleased they worked for you. I must admit that they turned out better than I expected as my first trials were only promising, but trying to do it with varying levels of daylight coming through the windows didn't help, so these were done at night. Maybe I should invest in some blackout blinds.
Im sure everyone hates if this happens with ones tools and machinery……. However rust is a very nice subject to shoot up close and specially in macrophotography.
Optics: Nikon 105mm AFD Microlens. Most shots are taken between f22-f32, hand held with natural light.
This has little to do with macro-photography as such (more about the colour of rust), but as a tip …
In the distant past, perhaps in my Ilford ‘Manual of Photography’
**LINK**, (when you could buy it for 30/-) I left mine behind in the UK; I read that orange and grey go well together. As some of your photographs indicate, it seems to work well with rust.

Thanks Sam. Interesting how some subjects we shoot looks more vivid on photos than actually seen. I've stared on the real subjects after I took the shot but the colours and contrast is not as vivid as when I stare on the final photo. The lens and the sensor likely filters out the light and enhances the image i guess. I might be wrong but a photograph always reveals details of the actual subject that we might not see in real time. The magnification also plays a big part on revealing the details at this level. Macro photography on its own genre is very vast. This includes shooting insects, still macro, artistic macro , extreme macro etc. Regardless of the shooting and subject preference, macrophotography and close up photography is such an interesting style of shooting. Keep posting your macros.
