Large T. rex Tooth in Matrix, 5.83"

Tyrannosaurus rex Tooth in Matrix
Lance Formation, Wyoming, USA
Late Cretaceous Period, approx. 66 million years old

An impressive, large Tyrannosaurus rex tooth preserved within its original Lance Formation matrix. Measuring an exceptional size (5.83 inches long) and retaining a substantial portion of its root, the specimen offers a striking glimpse into the anatomy of one of history’s greatest predators. While T. rex teeth are naturally shed throughout an animal’s lifetime, examples preserving such an extensive section of the root in their original matrix are considerably less common, enhancing both the scientific interest and visual appeal of the piece.

The tooth exhibits the robust proportions characteristic of T. rex, with rich dark enamel, pronounced natural curvature, and preserved serrations along portions of the cutting edges. The surrounding sediment provides valuable geological context, preserving the specimen much as it rested beneath the floodplains of the latest Cretaceous.

The Lance Formation represents one of the last dinosaur-bearing ecosystems before the end-Cretaceous mass extinction, preserving an extraordinary assemblage of ceratopsians, hadrosaurs, crocodilians, turtles, and apex predators including Tyrannosaurus rex. As one of the largest terrestrial carnivores ever to live, T. rex continually replaced its teeth throughout its lifetime, making shed teeth among the most iconic and sought-after dinosaur fossils.

Combining exceptional size, a partially preserved root, and natural matrix, this specimen is an outstanding display piece that beautifully captures both the power of Tyrannosaurus rex and the geological setting from which it emerged.
