Description:
This beautiful and striking Mammuthus primigenius molar comes directly
from the vast, harsh wastelands of Siberia. The preservation is
remarkable and natural mineral replacement processes in fossilization
that resulted in a spectrum of light brown hues. At a little over
3 lbs (1.388kg), its as heavy and dense as the rock it became since
tens of thousands of years ago when humans were still roving bands
of hunter gatherers. The woolly mammoths met extinction at the end
of the Pleistocene (12,000 years ago), probably as a result of climate
change together with the effects of human hunting.
The
molars of the woolly mammoth, like those of other mammoths and elephants
were large, specialized structures with a flattened grinding surface.
Low ridges of dense enamel run across the surface of the teeth,
making them ideal for grinding grasses. As with mastodons, a mammoth
will have a series of six cheek teeth (premolars and molars) on
each side of the jaw (a total of 24 teeth for both upper and lower
jaws.) Younger mammoths had three teeth on each side, while most
adults had two, and the old animals had one. As the teeth were worn
down, they were replaced by teeth growing in from the back. Newer
teeth were larger and contained more ridges than older teeth.
I also
need to dispel self-serving disinformation I’ve seen on the
Internet regarding Mammoth teeth from Siberian sedimentary deposits,
compared with those brought up from the sea. The former are clearly
more aesthetic, and the natural preservation and structural integrity
has not been compromised by the adverse chemical effects and dissolution
during sea water submersion as in the latter. The former smells
like the rock that it is and the latter smells like the hydrocarbons
required to restore structure integrity with many shellac-like coating.
At the 2008 Tucson Fossil show, the former were scarce and relatively
expensive, and the latter were prevalent and pretty inexpensive.
Pitching fossils as investments reminds me of the coin and pawn
shop near where I grew up. If I thought fossils were good investment
vehicles, I would recommend Mammoth teeth from Siberia, so don’t
be duped by the disinformation. The Mammoth teeth from the North
Sea are just fine, especially since they should be a bargain compared
to those from Siberia, if you don’t mind the smell. The Siberian
teeth are also safer around small children.

someone who is wrong is also very effective in making his point.”
