🚨New paper alert!🚨
Earliest known instance of pyrite ca. 400 kya at Barnham (UK), in layers with strong evidence of fire use, in an area with no naturally occurring pyrite nodules, together strongly suggest these pre-Neandertal peoples were making fire!

Marcell Fóti, author of The Natron Theory, is featured on my website this month. Marcell's book examines the perplexing mystery of megalithic construction and describes experiments that bring to light an ancient recipe for casting stone.

Could ancient Egyptians do this? Sure, they were smart. Did they? Maybe to a limited degree, I don't really know. For ALL the blocks? I'm skeptical but happy to be proven wrong. Could geologists (now and in the future) tell the difference? I'm thin section, almost certainly!
Probably easier, cheaper, and safer (easy to break) to send samples to a petrographic thin section preparation service (Google it), rather than buy a couple of rock saws, epoxy, glass slides, polishing equipment, etc. You'll also need a petrographic 🔬 to look at them properly.
He's not making amorphous glass. He's growing quartz crystals around feldspar crystals that were never destroyed. Good luck putting an age on them.
Easy to prove: Make a thin section of a piece a stone you think is artificial and stick it under a petrographic microscope using cross polarized light. Turning the stage, quartz alternates black/gray/white (anisotropic), while amorphous glass will always appear black (isotropic).
Weak stress birefringence in (hardened) glass can appear as a patchy pattern of bright or colored areas, often concentrated near edges, but since it's amorphous (i.e., no crystals), it will not exhibit the clean, systematic extinction typical of anisotropic minerals like quartz.
A friend just told me there is a “Flint Dibble” meme coin $Dibble
@KurtMetzger said yesterday on @joerogan that it will “go to the moon”
I don’t know much about crypto other than it is stupid and bad for the environment. A few thoughts:

After being buried on the editor's desk for over a year, my manuscript on experimentally testing the utility of manganese dioxide powder as a #fire-starting aid has seen the light of day! 😅 #Neanderthals #archeology link.springer.com/article/10…
Congrats! Could have been a preprint for this year, already readable by everyone, and peer-reviewed transparently in the meantime by our community! 😜
This is a fun read 😁 Way to not only only the line, but gain back some ground for #archaeology, @FlintDibble! 💪
