 Several professional paleoartists recommend the consideration of contemporary animals in aiding accurate restorations, especially in cases where crucial details of pose, appearance and behavior are impossible to know from fossil material.For example, most extinct animals' coloration and patterning are unknown from fossil evidence, but these can be plausibly restored in illustration based on known aspects of the animal's environment and behavior, as well as inference based on function such as thermoregulation, species recognition, and camouflage.In addition to a scientific understanding, paleoart incorporates a traditional approach to art, the use and development of style, medium, and subject matter that is unique to each artist.
