ULTRA RARE
LARGE
BLANCAN PLIOCENE AQUATIC VERTEBRATE LIFE FOSSIL BONE BED
IN ROCK WITH TURTLE,
FISH, SHARK AND CRUSTACEAN REMAINS IN SANDSTONE
Suwannee River - Florida, U.S.A.
PLIOCENE PERIOD ( BLANCAN
): 4.75 - 1.8 million years ago
Vertebrate North American
fossils from the Blancan Period are not commonly seen in private
collections. There were many unusual beasts of this era, many that most
people are not ever aware of. It was during this era that a land bridge
was re-established between North and South America allowing an
interchange of some amazing creatures between the two continents.
Creatures that walked the earth during this time included apex predators
such as various species of bone-crushing bear dogs, saber cats and
possibly some of the prey they fed upon such as primitive three-toed
horses, giant ground sloths and giant armadillos. Fossils that
represent life from this period are prized amongst collections.
This was a time in North America before the end of the last Ice Age.
For marine life, it was the prime period of the existence of the
Megalodon Shark - the most fearsome predator to have ever lived in the
ancient seas.
This is one of the most
unusual and rare marine vertebrate bone bed specimens from southeastern
North America we have ever seen in original matrix as it was discovered
- a Blancan Period 'in situ" silicified matrix bone bed of aquatic life
from southeast North America.
It came from a site and layer, that yielded species of mega-fauna unique
to this period of which those fossils were also found associated with
this piece but in surrounding loose sand that did not become silicified
as this piece did. A Blancan Period "in situ" specimen like this with the fossils embedded in a hardened aggregate
sandstone matrix on limestone is virtually unheard of in southeastern
North American deposits of any geological period much less during
Blancan Period. Bone bed
deposits are found in shell pits and river bottoms loose in sand or clay but this is an
extremely rare example of when the fossil-bearing substrate of a river
bottom becomes silicified to its limestone bed and entombs a myriad of
the animals that died in it long ago. This is a silicified sand
block on limestone of a number of fossils including remains of turtles,
shark, fish and crustaceans. No amount of photos can capture the
incredible dimension and 3D effect of this piece. It is truly a
prize specimen for any museum wishing to exhibit a prehistoric aquatic life
fossil bone bed
in situ
from North America - a type of specimen that
in of itself, is extraordinarily rare. You can stare at this piece
for hours and still find new fossils scattered densely throughout the
piece.
The
most prominent fossils bones are large vertebrae and carapace pieces of
the T. rex of freshwater turtles, the Alligator Snapping turtle,
Macroclemys temminckii, unique to southeastern North America.
This large predatory turtle
lived in prehistory up to and including the final Ice Age and beyond,
surviving extinction at the end of the Pleistocene Period. Fossils
of this terrifying looking giant freshwater turtle can be found but they
are almost always isolated fragments. A concentrated bed of bones
like this is, with other associated fossil teeth and bones in the
original matrix, is rare. Included also in this piece are smaller
turtle bones, a small vertebra from some type of shark, carapace pieces
from crustaceans, bones, fin spines and teeth of various panfish - a
perfect cross-section of the major vertebrate life-forms of a Blancan
Period river environment (likely brackish water due to the presence of
the shark vertebra.
This magnificent specimen
was discovered in a large pocket of loose sand beneath a clay and
limestone layer on the river bottom. The pocket yielded
several smaller but this was the only silicified portion of the
fossil-bearing bed that existed. We carefully exposed and cleaned
the surface that is shown rich in fossils, with fine micro-abrasive
tools. This fossil side was actually found upside down. The
other side showing the typical pock-marked natural surface of the
limestone was the side facing up. To allow safe-handling, we
treated the bone and matrix with a consolidant but none of the bones
were repaired or placed back in the positions as you see them.
Everything about this piece is 100% ORIGINAL AS FOUND. We received
the specimen as it was collected and all the lab work was performed by
us in our own facility.
NO RESTORATION OR FABRICATION and 100% ORIGINAL ASSOCIATION OF FOSSILS
AS FOUND.
This is an
astonishing
discovery and this
specimen can best be summed up as FAR BEYOND the rarity of most
vertebrate marine-life in-situ fossils.
EXTREMELY RARE AND EXTREMELY IMPRESSIVE TO
VIEW!
Macroclemys temminckii, or
Alligator Snapping turtle is
a species of the Macroclemys genus. The genus includes
three species: the extant
Macroclemys temminckii, the extinct Macroclemys
schmidti and the extinct Macroclemys auffenbergi.
M. schmidti is described from the early middle Miocene of
Nebraska and M. auffenbergi from the middle Pliocene of Florida.
This species dates back to prehistory but has survived the end of North
America's last Ice Age. Today, the Alligator Snapping Turtle is found only in North
America, predominantly in the warm southeastern states.
The
Alligator Snapping turtle can grow to large proportions with average
full-grown weights around 175 pounds and a shell 26 inches long.
Weight have been recorded at over 200 pounds. It is the largest
freshwater turtle living in North America today.
Their shell is made up of a series of pointed, heavy plates giving them
the appearance of an armored dinosaur. These turtles are
carnivores and scavengers, eating almost anything that comes their way.
Unique only to the Alligator Snapping Turtle, their mouths are camouflaged inside and they employ a worm-like
appendage that is used like a lure to attract small animals like fish,
near their jaws where upon the turtle can bite down with extreme speed
and force for a quick kill. The Alligator Snapping turtle
has a very powerful set of jaws and one can easily and quickly lose a
finger in careless handling of this primitive creature.
