I have always been fascinated by fossils, and once I
discovered ammonites, I feel like I’ve been possessed with fossil fever. Their
natural and unusual shapes, colors and sizes create endless opportunities for a
variety of one-of-a-kind fossils.
Ammonites got their name from the Egyptian God Ammon, the
God of life and procreation, who is often depicted with Rams’ horns behind each
ear. The fossil was considered Ammon’s stone, thus inheriting the name. The
snail-like spiral curl is the most recognizable attribute of ammonite fossils.
To me, that curl is the factor that draws my interest to those seemingly moving
fossils.
It is believed that ammonites were free-swimming mollusks
living around the same time that dinosaurs walked the earth, and disappearing
during the same extinction event. They grew in a range of sizes from a couple
of centimeters to over three feet in diameter. How fascinating is it to look at
those tiny ammonites and see the amount of detail preserved for all those
years.
Ammonite fossils are usually cut in half and polished to a
high shine on the cut side. The inner sections resemble a nautilus and are
often filled with minerals and sometimes druze (crystallized) pockets. The
exterior surface sometimes has an iridescent sheen in red, green or amber
colors. The underside is usually rounded where it is removed from the stone in
which it had fossilized. I love ammonite pendants that have holes drilled
across the top because you have access to the under side to enjoy the beauty it
brings, and not just the polished smooth inner surface.
While it is said that ammonites are found in every country,
there is an abundant amount found in Madagascar ,
in Africa . Many of the fossils we have found
in our travels to the Tucson Gem and Mineral shows have been from Madagascar .
However, this supply may be short-lived and it’s only a matter of time before
they become scarce and harder to find. This thought sends panic through my
body, but I console myself by remembering all the beautiful specimens in my
personal collection!
Along with uses such as bead embroidery, wire wrapping, cuff
links, I have even seen the larger sizes used as paperweights, sculptures, and
objects for home or office decorating. This fascinating remnant of earth’s past
living creatures is sure to spark your interest too!
