ULTRA RARE JUVENILE
SPINOSAURUS MAXILLA JAW SECTION WITH 15 TEETH
Tegana Formation - Kem Kem, Morocco
CRETACEOUS PERIOD: 96 - 66 million years ago
predatory dinosaur jaw rarely becomes available for sale. Most
Spinosaurus jaws we
have encountered on the market are fakes using crocodile or mosasaur
jaws with mismatched Spinosaurus
teeth glued into the sockets. Without the presence of any ORIGINAL
teeth still embedded in the jaw, it is impossible to attribute
the jaw bone to a specific species.
Such is the case the Spinosaurus aegypticus. Jaw and skull
elements of this ferocious prehistoric beast are perhaps, the most often
faked as popularity is high for this dinosaur and the round teeth can
easily be placed in the sockets of crocodile and mosasaur jaws that also
possess round, conical teeth. For the past decade, we have
seen these fabricated "jaws" selling for outrageous prices.
It is imperative to positively
identify a partial jaw of a dinosaur, if an ORIGINAL tooth is found
still embedded in the bone.
The fossil jaw offered here
is a very rare example and an opportunity to acquire a true Spinosaurus
maxilla. This is a large jaw section with 15 teeth from the upper
jaw from a juvenile dinosaur. There are 5 teeth that are either
worn or just beginning to erupt. There are 10 others that are
fully erupted. Several of the teeth have been added but all teeth
put in were carefully matched for size and position of the teeth
compared to known examples of similar specimens from other spinosaurid
remains. Several of the teeth are original which allowed a
positive identification of the jaw as to being Spinosaurus versus a
crocodile where fossil remains are also found in this same region.
The jaw has repair to fractures but there is no fabrication of the bone
or adding jaw bone from multiple creatures. Like modern predators
of today, dinosaurs did not have perfect rows of teeth all erupted and
matching in size. These predators had a constantly changing array
of teeth and due to the ferocity of attacking and eating living,
struggling prey, teeth always became broken and were in a state of
constant replacement. This superb specimen demonstrates that.
Genuine identifiable skull elements of any dinosaur are rare and true
cornerstones of advanced collections, whether public or private. Highly unique, rare and a serious paleontological treasure
with endless display appeal!
remains of Spinosaurus aegyptiacus were first
discovered by a German collector in 1912 in central Egypt. A variety
of pieces were recovered including a skull and teeth. On the evening
of April 24, 1944, a British bombing run on Munich destroyed these and
many other rare fossil specimens.
Spinosaurus is one of the
longest and strangest of all carnivorous dinosaurs. At 50 feet long
and 4 tons in weight, it was truly a monster! Its most unusual
feature was a row of broad club-shaped spines 6 feet tall, projecting
upward from the backbone. It's believed that these spines were
covered with a sail of skin which could be raised by the creature as a
social display or as a way to regulate body temperature.
To this day, no other
dinosaur has been found with such tall and broad-shaped neural spines.
Fossil remains of Spinosaurus aegyptiacus are only found in the
North African Sahara Desert. Contrary to the inhospitable desert
environment where Spinosaurus fossils are found today, this region was a
vast swampy tropical paradise abundant with life during the Cretaceous
Period when Spinosaurus was alive and inhabiting its muddy river shores
