The shape of the inner ear can tell scientists whether an animal was floating in the air, according to a study.
The authors compiled a matrix of inner ear data for 128 species, including modern animals such as birds and crocodiles, as well as dinosaurs.
The authors wanted to determine whether the inner ear provides information about certain behaviors. In many cases, researchers have created 3D models from often destroyed skull fossils.
After collecting the data, the researchers found clusters of species with similar features to the inner ear. These species, according to the authors, have similar modes of movement and perception of the world.
