New research reveals the truth about the dinosaur confrontation 65 million years ago

The discovery of Nanotyrannus helps clarify the relationship between small and large predatory dinosaurs, opening up many questions for scientists in the future.

In a new study published in the journal Nature, scientists made a surprising discovery about the dueling dinosaur skeleton discovered in 2006 in the Hell Creek region, dating back about 65.5 million years. Photo: Anthony Hutchings.

For many years, researchers have believed that the dueling dinosaur skeleton above is evidence of a battle between two iconic species of the Cretaceous period: Tyrannosaurus rex (T-rex) and Triceratops. Photo: NC State University.

However, after 5 years of analysis, the research team led by Dr. James Napoli (Stony Brook University) and Lindsay Zanno (North Carolina State University) made a surprising discovery. Photo: North Carolina Museum of Natural Sciences.

Specifically, the results of bone microscopic examination showed that the small individual in the fossil was an adult, not a baby T-rex as previously speculated. In fact, the small individual was a separate species - Nanotyrannus lancensis. Photo: NC Museum of Natural Sciences.

Nanotyrannus lancensis is a fast, agile predatory dinosaur, much smaller in size than T-rex. Nanotyrannus is about 5.5m long, agile, has long legs, and developed forelimbs to catch prey. Meanwhile, T-rex is about 12.8m long, has big, strong legs and possesses a powerful bite to hunt prey. Photo: Raul Martin.

Experts say the rest of the dueling dinosaur skeleton is still being slowly extracted from the rock and will be studied in the future to solve other mysteries. Photo: dinosaurland.es.
