Here is news from Argentina. Scientists find some fossils. The bones are very old. They are the bones of dinosaurs. The bones are around 90 million years old.
The bones are important to the scientists. The bones are very big. There are a lot of them, too. Experts find some teeth, as well. The teeth can tell them what this animal ate.
Difficult words: scientist (clever person who is an expert in something), fossil (old bone that turned into rock), expert (person who knows a lot of about something).
