Answer:

Deducing paleontological evidence leads to discoveries about the behaviour of an organism as well. For example, a single site contained more than 10000 fossil skeletons of Hadrosaurs (duck-billed dinosaurs) which presented the palaeontologists with the social behaviour hypothesis of Hadrosaurs that they lived in herds.

Paleontology

Paleontology is the study of the history of life on Earth as based on fossils. Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock.

Lords of the Brazilian Sky

Dr. Alexander Kellner and local museum founder Placido Cidade Nuvens show the next generation of paleontologists a pterosaur fossil found near their village on the Araripe Plateau in northeastern Brazil. Kellner helps demonstrate how pterosaurs became "Lords of the Brazilian Sky"—the name of one of his books.

Paleontology is the study of the history of life on Earth as based on fossils. Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock. Paleontologists use fossil remains to understand different aspects of extinct and living organisms. Individual fossils may contain information about an organism’s life and environment. Much like the rings of a tree, for example, each ring on the surface of an oyster shell denotes one year of its life. Studying oyster fossils can help paleontologists discover how long the oyster lived, and in what conditions. If the climate was favorable for the oyster, the oyster probably grew more quickly and the rings would be thicker. If the oyster struggled for survival, the rings would be thinner. Thinner rings would indicate an environment not favorable to organisms like the oyster—too warm or too cold for the oyster, for example, or lacking nutrients necessary for them to grow.
