ULTRA RARE 1.1 MILLION YEAR IRVINGTONIAN
PERIOD 10.4 INCH
FOSSIL TRACHEMYS TURTLE SHELL WITH INTACT PLASTRON
Spring Deposit - Gilchrist County, Florida, U.S.A.
EARLY PLEISTOCENE PERIOD
(IRVINGTONIAN ERA): 1.1 Million years ago
This
is truly one of the most impressive and rare turtle specimens we have
had the pleasure to offer. It is a remarkably well-preserved carapace of
a 1.1 million year old Pond Turtle of the species Trachemys.
The amazing condition and completeness of this specimen lends itself to
the unique deposit in which it was discovered - an undisturbed fissure
in a freshwater spring deposit that has been dated to the Irvingtonian
Period of the Pleistocene, at 1.1 million years ago. In this
fissure and period were also found several fossil alligators of a rare
degree of completeness we have NEVER seen. It was literally a 1
million year time capsule and because of this, it has produced this
incredibly rare specimen of this turtle fossil. Typical fossil
deposits where these are found are rivers that fragment and scatter the
shell so that all that is usually found are individual pieces of the
carapace. Any time spent in the southeastern part of the United
States collecting fossils will aptly demonstrate just how rare an
occurrence of a find like this is! The shell was found in a pocket
in pieces and has been carefully reassembled. There was only a few
small portions of the carapace missing that amounted to approximately 1%
of the total surface of the shell requiring restoration. The
entire array of delicate fringe scutes on the posterior are 100%
original and any missing portions were left as they were found. We
performed all of the restoration and work to the carapace in our on-site
lab facility so we can accurately attest to the degree and nature of the
work done on this superb specimen.
Remember, this is not a
borderline Holocene specimen or similar to the many fake "Pleistocene"
fossils you see on the market made up of modern animal remains soaked in
dye. This is a true fossil carapace with a definitive dating to
this period of the Early Pleistocene, Irvingtonian Age. Specimens
like this are a once-in-a-lifetime discovery when this complete and in
this state of preservation. The color is natural and ranges from a
mottle caramel brown to incredible accents of mottle bright orange,
red-brown, and light cream brown. This will be one of our most
memorable specimens of any turtle fossils we will ever offer.
The
oldest fossil turtles found date back to the Triassic Period in Germany
with Progaochelys and Proterocheris. Before the end
of the Cretaceous Period, most modern turtle groups existed with
representatives in existence. Florida's oldest fossil ever found
is a marine turtle dating to the Cretaceous. Portions of the
creature were collected 9210 feet below the surface of Okeechobee County
during well-drilling in 1955. Turtles
have highly specialized anatomy for living in their environment.
The upper carapace is formed from the fusing of individual bony
elements. Thoracic vertebra are fused to the inside of the upper
carapace. The underside flat portion of the shell is called the
PLASTRON. The overall shape of the carapace indicates the
environment in which the turtle or tortoise lived in. High-domed
shells indicate land-dwelling species while low-domed shells are more
hydrodynamic and indicate an aquatic life. Even though the do not
possess teeth, most turtles are carnivores. The
Box turtle is a partially aquatic turtle that spends most of its life on
dry land near shallow fresh water. A woody grassland area with dry
sandy soil on top and humid earth beneath is also needed for their
survival. The American box turtle can be found today in eastern,
central and southwestern United States and in the northern parts of
Mexico. The majority of their life is spent foraging for food on
land. To keep away from predators, they build their homes in
burrows under fallen trees or rocks. When they are young, they are
omnivorous but as they reach adulthood they eat mostly vegetation.
The Eastern box turtle, Terrapene carolina, is a woodland species found
in the eastern and central United States. There are records of Box
turtles living for 80 - 100 years but most live around 30
years. What
makes box turtles so unique is the hinge in the plastron. This
allows them to completely withdraw their legs, tail, head and neck
within the shell for protection from predators hence the name, BOX
TURTLE. If a predator attempts to eat a box turtle, it will not
find anything to nip at. The sturdy shell protects the turtle
until its enemy gets frustrated and goes away. This feature is not
true of aquatic turtles. A few aquatic turtles have hinged
plastrons, but most do not as they are almost always near water, which
allows them a quick escape from danger. TRULY
