Battle of the Dinosaurs

Skeletons of a T. rex and a Triceratops were recently discovered­. Did they die fighting each other? 

In a flash, the T. rex jumps onto the back of the Triceratops—and bites down. Its sharp teeth are as big as bananas. With a mighty roar, the Triceratops swings its giant head around. It tries to spear the T. rex with one of its three deadly horns.

A battle like this might have taken place millions of years ago. Paleontologists recently dug up fossils of two dinosaurs in a Montana hillside. They say it’s possible the dinos were locked in a bloody duel when they died.

This is the skull of the T. rex dueling dinosaur. It's missing teeth here that might have snapped off in battle. 

The two dinos, a Triceratops and a T. rex, lived 67 million years ago. They roamed in what is now the American West.

After the dinosuars died, their bodies slowly became fossils. In 2006, paleontologists found the Triceratops skeleton. And later they spotted the T. rex.

The fossils still need to be fully studied. But scientists say they’re the best examples of a Triceratops and T. rex ever found.

Why do experts think they might have been fighting? The skeletons were found overlapping each other. And T. rex teeth are stuck in the spine of the Triceratops.

Even with these clues, scientists can’t be positive that these two fought. The teeth might have come from another T. rex.

Dueling Dinos

Paleontologists at the North Carolina Museum of Natural Sciences are on a mission to learn more. The museum will soon be home to these dueling dinosaurs.

Lindsay Zanno is a paleontologist at the museum. She says when dinosaur fossils are dug up, the skeletons are usually missing many bones.

“But the two whole skeletons that make up the dueling dinosaurs are incredible,” Zanno explains. “Both dinosaurs were buried with all of their skin, muscles, and organs intact!”

Zanno and other experts will have an amazing opportunity to study the fossils up close.

Over time, the fossils could reveal new information about the dinos’ bodies. They might also finally answer the question: Did this pair battle it out to the death?

1. Based on the article, what do you know about the work of paleontologists?

2. Why do scientists think the fossils of two dinosaurs unearthed in Montana show that the dinos could have been fighting each other?

3. According to the sidebar “Ask a Fossil Hunter,” what steps do scientists take to get a fossil out of the ground?
