 Since paleontological knowledge and public perception of the field have changed dramatically since the earliest attempts at reconstructing prehistory, paleoart as a discipline has consequently changed over time as well.This has led to difficulties in creating a shared definition of the term.Given that the drive towards scientific accuracy has always been a salient feature of the discipline, some authors point out the importance of separating true paleoart from "paleoimagery", which is defined as a broader category of paleontology-influenced imagery that may include a variety of cultural and media depictions of prehistoric life in various manifestations, but does not necessarily include scientific accuracy as a recognized goal.
