"BONE-CRUSHING BEAR-DOG" JAW WITH INTACT CRUSHING MOLAR TOOTH
Suwannee River, Florida, U.S.A.
EARLY MIOCENE PERIOD:
20 - 18 million years ago
The bizarre fauna of prehistoric Florida
is nothing short of fascinating. Amongst every type of animal that
ever walked this part of the planet millions of years ago, fossil remains
horrific and ferocious beast ranks as one of the rarest as its entire family lineage emerged and then
went completely extinct during the Miocene Period. This EXTREMELY valuable
specimen dates back to the ARIKAREEAN AGE, a term used in the scientific
community as part of the North American Land Mammal Ages (NALMA).
These ages represent periods on the geologic time scale as they relate to
this type of fauna.
Of all the fossils we
will ever offer, this specimen will always rank as one of the rarest based
on known remains and scientific evidence of Florida's fossil record for
this creature. This is a right anterior mandible of the giant bone-crushing bear-dog Amphicyon
longiramus. In the Early Miocene of Florida, no animal was more
deadly. This mammal was the apex predator of its time and had no
equal. Never before have we been fortunate to offer ANY fossil from
this rare and little known about beast. It is likely you will never
see anyone offer specimens of this animal!
The entire bone of this
specimen is completely fossilized and heavy as stone. The color
throughout the bone and tooth is pure jet black giving the fossil a
sinister and evil appearance - fitting for such a deadly predator.
One intact bone-crushing molar is still embedded to the jawbone and is
original as found. It appears broken but it is not. The
chewing surface is well-worn from feeding when the beast was alive and
indicates this specimen came from an old, full-grown animal with years of
killing and bone-crushing experience! Surfaces of the tooth and bone
are nothing short of spectacular and color and sheen are natural! NO REPAIR and NO RESTORATION.
For the fossil of a
lifetime in rarity and display appeal, this is definitely
top recommendation of ours!
Made famous in the BBC
digital television presentation "Walking with Prehistoric
Beasts", the bear-dogs were ferocious carnivores that ranged from the
size of a medium dog to the size of a bear. These predators known as
Amphicyonids were neither dogs nor bears but were more closely related to
bears. They emerged and subsequently went extinct during the
Miocene, once inhabiting regions of Eurasia and North America.
Amphicyonidae were a
diverse group with species resembling all or part of modern dogs, hyenas
and bears. Leaner built species had cheek teeth designed for
shearing meat whereas the stouter and larger species had teeth designed to
crush bone. Males were larger than females. They lived in dens
and had the ability to dig large burrows.
Amphicyon longiramus was
the largest of the Florida species at the size of a full-grown bear.
This species evolved in Eurasia and migrated to North America. A.
longiramus was the top predatory land mammal of its time in Florida during
the Early Miocene. Its skull was long in comparison to its body size
but brain size was lacking. Its posture and structure were similar
to a bear and it is theorized that it must have hunted using ambush
techniques that are used today by modern grizzlies. Most likely,
this giant bear-dog burst upon its unfortunate victim at close range and
dealt its prey a single deadly blow with its massive forepaw. This
theory of attack is also based on its relative the bear as it was incapable of sustaining long runs in pursuit of prey.
Compared to lighter species of Amphicyonids, Amphicyon longiramus had heavy
posterior dentition allowing it to crush bone in its jaws.
VERTEBRATE FOSSILS FROM THE EARLY MIOCENE OF FLORIDA ARE SUPER RARE AND
ONLY FOUND AT A HANDFUL OF SITES - EXOTIC AND VERY HIGHLY
BEAST WAS THE APEX PREDATOR OF FLORIDA IN THE EARLY MIOCENE AND HAD
