Read the story

Scientists have studied a dinosaur bone found in Brazil. The fossil is about 115 million years old.

The team found tiny shapes inside the bone. The shapes may be the remains of red blood cells. The team also found traces of a chemical linked to blood.

Other experts are not sure that the shapes were blood cells. More research is needed to understand the find.

The dinosaur is called Aratasaurus. Its bone was found in a mine in 2008.
