He noticed a wild frog living in his fence post, so he built a 3D-printed home for the frogs to live and hide. [πŸ“Ήunknowndazza]

Our summer school program uses a plush D for a mascot. His name is Jeff. He goes on all field trips, has lots of adventures, and loves anchovy ice cream. He has an Instagram too.

I have always thought sprites inspired some of the art work and stories from northern Australian indigenous communities.

Yes. Thanks for asking. The new drugs seem to be working. Find out more on Thursday. I'll be back on cycle 7 soon I suspect.

Pyrite's cleavage is best described as poor or indistinct. Definitely not the best mineral to be using for a beginner when teaching about cleavage. That said, it is a good challenge for advanced students.

Sometimes the joy is in sharing, showing someone what you can see that they are oblivious of. And it can be anything, not just fossils.

I have a 3 page primer on clastic sediment and sedimentary rock classifications I can make available in a generic form if it helps. Written for High School students (and their teachers).

The laws on this are not universal but generally considered illegal without notice and agreement on time etc. You should get the facts for the jurisdiction you are in before deciding what to do.

It was a line being followed decades ago when the large igneous province proponents were making the case that lip emissions were weakening the dinosaurs. Some were even arguing that the lip caused the extinction and the asteroid, if it exists all, was just incidental if I remember right.

Ok, spore dispersal or light are potential drivers. I'd expect symbiotic things to be secondary rather than primary drivers. What else might drive them upwards?

I have always found the fungal idea problematic because what possible evolutionary pressure could drive the development of such massive vertical structures? I have always suspected they were some novel independently developed photosynthetic thing reaching for the sky away from the ground dwellers.

Nice pegmatite. You'll find lovely feldspar at the triple chance mine site, once a major source for the ceramic industry. Also big sheets of mics used for toasters and valves and a great story connecting the beryl to NASA and the Apollo program.

Morphological diversity in Brooksella alternata and concretions from Weiss Lake locality.

Sediments and minerals self-organize and create a range of patterns which can be difficult to distinguish from biologically fabricated structures. This review brings significant advancement in understanding the deep time biospheres on Earth and elsewhere.

Limestone. Looks like a mix of bivalves and gastropods but the small stuff might be fragments of other things. The shelly material is calcium carbonate, the go to material for most shelly things. If originally aragonite it is unstable over geo time and recrystallises to calcite in situ.

Your posts have been interesting and engaging. Some doors open as others close. You can and will find a way. 2025 was a crap year for me medically but I sincerely hope 2026 is better for all of us re the previous year's crap.
