Own a genuine piece of prehistoric ocean history with this 3.86-inch fossil Mosasaur jaw section, preserved beautifully in its natural matrix and featuring one visible Mosasaur tooth. The tooth measures 1.37 inches, while the full matrix measures 4.88 inches, making this an eye-catching and highly collectible marine reptile fossil from the Late Cretaceous period, approximately 70–66 million years old.
Unlike a single loose tooth, this authentic Mosasaur jaw fragment preserves part of the original jawbone with one associated tooth still in place, offering a much more dramatic and scientifically interesting display. The tooth shows excellent natural enamel, attractive earthy coloration, and visible root structure, while the jaw section adds impressive texture and realism that makes this piece feel truly “as found.” Fossils like this offer a rare glimpse into the feeding anatomy of one of the ocean’s most feared apex predators, often called the “T. rex of the Sea.”
This is 100% natural fossil material with no restoration, no composites, and no replicas, just a genuine piece of ancient marine life preserved in stone for millions of years.

About This Specimen
This Mosasaur jaw section is a fantastic display piece because it preserves one tooth still naturally set within the jawbone, which is far more visually compelling than an isolated tooth alone. The tooth measures 1.37 inches and shows solid natural enamel with a pleasing glossy finish and classic recurved shape. The smaller associated teeth help complete the jaw section and give the specimen a more complete, anatomical look.
The exposed jawbone adds a great deal of character to the fossil, with natural texture, layering, and preservation that highlight the authenticity of the specimen. The surrounding matrix frames the fossil nicely and gives it strong display appeal, whether shown flat in a cabinet or elevated on a stand. Overall, this is a highly collectible Mosasaur fossil that offers both display value and educational value in one genuine prehistoric piece.
Why This Specimen Stands Out
- Genuine Mosasaur jaw section with 1 associated tooth
- Preserves the natural placement of the tooth within the jaw for added scientific interest
- Much more unique and visually striking than a single loose Mosasaur tooth
- Natural matrix enhances authenticity and gives the fossil a rugged “as found” appearance
- Excellent collector specimen from one of the most iconic marine reptiles of the Late Cretaceous
- Ideal for fossil collectors, educators, marine reptile enthusiasts, and display collections
Authenticity Guarantee
At Fossil Driven, every fossil we sell is carefully inspected and verified for authenticity. This specimen is 100% genuine fossil material with no repair or restoration unless clearly stated. No casts, no replicas, and no composites, just a real piece of Earth’s ancient past.
About Mosasaurs
Mosasaurs were massive marine reptiles that ruled the oceans during the Late Cretaceous period, around 70–66 million years ago. Often nicknamed the “T. rex of the Sea,” these powerful predators could grow over 50 feet long and were equipped with strong jaws and sharp, conical teeth designed to grip slippery prey.
Although they lived alongside dinosaurs, mosasaurs were not dinosaurs. They were marine reptiles more closely related to modern monitor lizards and snakes. Their long bodies, paddle-like limbs, and powerful tail flukes made them fast and efficient swimmers capable of hunting fish, ammonites, sharks, turtles, and even other marine reptiles.
Jaw sections like this are especially desirable because they preserve more of the actual animal than a single tooth alone. Instead of just owning one isolated tooth, this specimen gives you a direct look at the original jaw structure and tooth placement of one of prehistory’s top ocean predators. Fossils from the Oulad Abdoun Basin of Morocco are some of the most sought-after Mosasaur fossils in the world, known for their preservation and abundance of Late Cretaceous marine life.
At Fossil Driven, we are passionate about all things fossils. Every specimen we offer is selected for authenticity, quality, and collector appeal, bringing genuine prehistoric history into the hands of collectors who appreciate the real thing.
