The dinosaur would have been about 90 feet long and weighed about 30 tons.

It was a sauropod, a type of dinosaur that eats plants and has a long neck and tail.

Nagatitan lived between 100 to 120 million years ago.

It gives clues about how dinosaurs got even bigger later on.

Carol Labinder is an economics professor at the University of Texas at Austin.

The tariffs could be challenged again in court, but in the meantime, economists say don't expect any big price cuts.
