Ammonium bifluoride solution in water. It will dissolve the fine-grained silica, but attack the coarser stuff much more slowly. So, if you time it right by checking frequently, you can increase the co ...

Got it out of the Karo and dried it off. This is a view of one of the legs. It appears to be increasingly fine sand grains, all glued with what might be pollen. I'm going to try some cleaning chemi ...

I laid the specimen in a Karo bath under the microscope, so these images are through the surface of the syrup and a thin layer of LDG. I positioned it to make the Karo as thin as possible, but the fo ...

Just free-range thinking here. The legs seem to go the wrong way for the cavity to be the body of the insect the legs belong to. But if that's the body of an insect the legs were grasping, it makes ...

This one definitely caught my attention. I bought it because frankly it looked like an insect. I'm not ready to jump into the deep end of the pool and assert that yet, but it's certainly evocative o ...

I had to up my photography game a bit. Got a new camera that can do better macro shots, and a lighted turntable to shoot small objects. This is a 3D model built from the blue silicone cast shown in ...

I see epigenetic inclusions in LDG_14, not leaves.

I don't know what you intend epigenetic to mean in this context. You're certainly free to hold any opinion, I'm merely presenting what I see and ...

An impression is a fossil.

Where could this radioactivity be coming from?
What's more, beta radiation has moderate penetrating power.

I don't know the source process, but it almost certainly comes from the sun. We have mic ...

Still the ignition temperature of a seed is in the order of 2-300 C and melting point of glass is around 800 C.

When silica is fluidized by beta radiation, the melting point is immaterial.

Dear Creg, I admire the perseverance and illusion you put into your study.
However, you cannot hunt for fossils inside a glass that was formed at temperatures estimated to be above 2750°C. If the roc ...

Here's a neat fossil, first one like this I've seen. Appears to be something like a berry stem. I found it partly chopped off while grinding this face down to polish it and get a better look inside. ...

Here's a totally fascinating development. I have a couple pieces that in my last pdf I said were good candidates for having chains of sand grains, based on their overall shapes. I ground a flat on e ...

In the images above, there's a whitish knob on the bottom of the piece, apparently quartz. I cut that off and polished it. The glass has lots of inclusions, so the fossil is still hard to see. So I ...
