ULTRA RARE JUVENILE SPINOSAURUS MAXILLA JAW SECTION WITH 15 TEETH

Tegana Formation - Kem Kem, Morocco

LATE CRETACEOUS PERIOD:  96 - 66 million years ago

A 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!

 


The 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 and bogs.
