Tooth of Mosasaurus Prognathodon anceps 5.4cm x 2.8cm x 2.2cm

An Impressive Mosasaur (Prognathodon anceps) Tooth from the Late Cretaceous – Morocco

This stunning fossil tooth of Prognathodon anceps measures 5.4 cm in length, 2.8 cm in width, and 2.2 cm in depth. It stands out for its excellent preservation, with no repair or restoration—offering a pristine glimpse into the jaws of one of prehistory’s most powerful marine predators.

Collected from the rich phosphate beds of the Khouribga region in Morocco, this specimen is a rare and authentic piece, ideal for collectors, educators, or anyone captivated by the prehistoric oceans.

Prognathodon anceps: The Apex Predator of the Cretaceous Seas

Prognathodon anceps, a species of mosasaur, ruled the marine world around 80 to 66 million years ago. Related to monitor lizards and snakes, these massive reptiles could exceed 10 meters in length and had incredibly powerful jaws equipped with thick, conical teeth. Their fearsome appearance has even earned them a spot in popular culture, notably in the Jurassic World film series.

Unlike other mosasaurs, Prognathodon was not a specialist but a versatile predator. Its teeth, built for both slicing and crushing, suggest a broad diet that included:

• Ammonites and shelled mollusks

• Fish and cephalopods

• Turtles and even other marine reptiles

Key Features of This Tooth

• Large, solid dimensions: With a robust structure, this tooth exemplifies the bite force and durability required to dominate the Late Cretaceous seas.

• Natural enamel preservation: The enamel is thick and slightly glossy, resistant to erosion—a trait evolved to handle armored prey.

• Crenulated surface: The subtle serrations along the crown hint at its meat-slicing functionality, increasing grip and cutting power.

Paleontological Significance

• Identification marker: Teeth like this help paleontologists distinguish Prognathodon from other mosasaurs, thanks to their thickness and shape.

• Behavioral insights: Wear patterns and enamel preservation offer direct evidence of diet and feeding strategies.

• Global distribution: Fossils of Prognathodon anceps have been found across Europe, North America, and North Africa—proving their ecological success and adaptability.
