Nooo, Just not supplied here yet. Amateurs built the Ark and experts built the Titanic, so they say.circumspice wrote: ↑Fri Jan 14, 2022 10:34 amBeing sceptical is essential to being a good scientist, being open to ideas, and suggestions is also. There is little point for me to try to prove anything to you, you said you could not see something that I believe most would find easy to see. I only have more of the same things that require seeing things. Its clearly not for you.
In other words, you have no credentials at all. 'Nuff said.
I have no idea why you've fixated on the erroneous notion that fossilized mastodon, mammoth & walrus ivory is petrified or somehow converted to stone. In places where the permafrost never thaws completely, the ancient ivory doesn't truly fossilize. Artisans have used what is euphemistically called fossil ivory for thousands of years. It is no harder than fresh ivory, it hasn't been converted to stone. You might want to research the subject before spewing false info.PointBlank wrote: ↑Fri Jan 14, 2022 10:35 am The item is made of fossilised mastodon bone from the Pliocene period, 5.2 million to 2.5 million years ago.

Although believed to be carved when the mastodon bone was already fossilized, examining the object I cannot possibly see how this can be the case, as its as hard as any flint, but does not have the usual signs of knapping that a flint would show. I can see other figurative possibilities in this find beside the obvious face, yes things from my chart.

Just like almost everything else then, no evidence of evolution.
What is fossil ivory? Is it petrified? Can you carve it?
A: Fossil ivory is found all over the world, but the only kind considered useful for carving is found in regions of the far north where the ground is frozen for all but short periods of the year. Instead of decaying or undergoing petrification, ivory from animals that died hundreds or even thousands of years ago often remains much as it was, sometimes taking on coloration from surrounding minerals. This can often result in startling colors and patterns, which may be brought out by skillful carving and polishing. Shades of brown are most common, but some mastodon ivory, for example, exhibits a startling blue venation.
I have no idea why you would have the erroneous claim the item is not stone.

You're the one making the claims. The burden of proof is upon YOU. Thus far, you've managed to make some very unbelieveable claims & you haven't offered a shred of proof. Yet you demand belief. Your credibility is suspect. Like I said: Put up or shut up. The ball has always been in your court, yet all you can do is whine that I don't believe you because I believe false teachings from the established authorities on the subject at hand. So... prove them false. Don't just say that they are telling lies. PROVE THAT THEY ARE TELLING LIES. It should be a simple thing for you to do if you're not full of shit.PointBlank wrote: ↑Sat Jan 15, 2022 12:31 amI have no idea why you would have the erroneous claim the item is not stone.

It does not mater if you have heard of gold plated mastodon bones as soft as jello that glow in the dark, THIS ONE IS STONE, the point i was making is very clear, it surely was sculpted before it was stone. You might want to actually read what you post before making any claims and ignorantly spewing false info
The ages that are given match the supposed time line of a particular type of mastodon, and seeing as it was in the hands of a palaeontologist before myself, I think he had recognized the particular type of mastodon and thus we have the age ranges.
If it’s not made of something that does not permit a conchoidal fracture, like all the forms of cryptocrystalline quartz do, such as flint, then it could not be “knapped” like flint. Many hard stone tools, and stone effigies I have seen attributed to Native Americans(and I have seen many, and if it were a little easier for me to add photos to this site I could show some; been involved collecting Native American artifacts for some 65 years now) we’re in fact pecked and ground into form, not knapped into form. Knapping is not the only way to reduce rock. And knapping is used pretty exclusively to produce flaked stone artifacts, not effigies. A few exceptions, such as flint thunderbird effigies, however 99.999999% of flint thunderbird effigies are modern fakes.PointBlank wrote: ↑Fri Jan 14, 2022 10:35 am The item is made of fossilised mastodon bone from the Pliocene period, 5.2 million to 2.5 million years ago.
