of Sporormiella spp. to estimate the ages of
meagfauna extinctions in his lecture. How this is
done is discussed in:

Although the Deccan traps started erupting prior
to the Chicxulub asteroid impact, it has been
proposed that the Chicxulub asteroid impact
resulted in cataclysmic eruptions of the already
active, but relatively sluggish, Deccan trap fissure
eruptions. Go seee;

Great Articles About Fake Amber and the "Piltdown Fly"
Great Articles About Fake Amber and the "Piltdown Fly"
There is a great feature article about fake amber and fake
fossil inclusions in amber. It talks about the various ways
of faking and enhancing amber.
The paper is;
Erikasson, M. E., and G. O. Poinar, 2015, Fake it till you
make it—the uncanny art of forging amber. Geology
Today. vol. 31, no. 1, pp. 21-27.
http://onlinelibrary.wiley.com/doi/10.1111/gto.12083/abstract
This article also has a marvelous picture of a piece of
"amber" that contains a trilobite. This trilobite can be
seen on the 10 TONS / Models and paleontological
reproduction Facebook page at:
