Description:
Central Nevada has a host of Miocene fossil leaf sites. The leaves
from this one are preserved in paper shales and exhibit the best
preservation I have encountered. Some of these shales are incredibly
fragile, nearly as thin as a sheet of paper. I encourage you to
not handle these specimens. On this on in particular, you will notice
that that some of the edges of the thin paper shale layer on which
the leaf is preserved are a bit frayed. However, the specimen is
stabilized by the Riker Mount.
The
state once had a much wetter and more temperate climate back in
the Miocene. There were many more lakes in what is now the driest
state in the USA. The Sierra uplift dramatically changed the climate
and rainfall in the state.
The
specimen will be shipped in an attractive 6 x 8” glass covered
Riker mount. The specimen will be labeled.
