In September 2025, recent excavations by paleontologists discovered the bones of a massive creature, rumored to be a tyrannosaur, one bigger than all its predecessors.

Named “Goliath”, the dinosaur’s femur length was 137.1 centimeters with a circumference of 64.77 centimeters.

This surpasses the previous record holder “Sue” whose femur measured 132 centimeters with a circumference of 58 centimeters.

The femur, excavated by Loren Gurche and Lauren McClain in 2024 at Harding County, South Dakota, is currently on display at the Black Hills Institute booth at the Tucson Gem and Minerals show.

Both measurements were confirmed by Dr. Brian Curtance and Peter Larson through multiple processes, additionally determining that the breadth of the midline bone was at least 218 mm.

However, there are recent controversies that accuse Larson of incorrectly measuring the bone size of Goliath.

Some paleontologists claim his measurements began at the medial trochanter instead of the lateral side of the femur’s trochanter, potentially exaggerating the measurements to be only as large as Sue’s femur.

Despite this ongoing measurement controversy, the focus remains on what science already knows about this legendary prehistoric predator.

Tyrannosaurus is a genus of large theropod dinosaur. 

The type species Tyrannosaurus rex, often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods. 

It lived throughout what is now western North America, on what was then an island continent known as Laramidia.

At around 12-20 feet tall, the Tyrannosaurus Rex earned its title as ‘Tyrant Lizard King’, one of the most imposing figures in the age of the dinosaurs, weighing up to eighteen thousand pounds. 

The discovery of Goliath has opened new doors for understanding the diversity and evolution of theropod dinosaurs and their potential size.

This remarkable specimen represents a new step in paleontology, pushing the limits of what scientists previously thought was possible for the Tyrannosaurus genus and their physical dimensions.

According to current evidence, these measurements make Goliath the largest Tyrannosaur femur discovered thus far in the history of paleontology.

Ongoing research continues to examine this exceptional find with experts from around the world weighing in on its authenticity and importance.

If verified conclusively, Goliath would be a pivotal discovery in scientific understanding of prehistoric apex predators.
