Abstract: Dinosaurs are one of high profile symbols in paleontology. They dominated the Mesozoic terrestrial and marine ecosystems and therefore are of great significance to study the Earth evolution. In recent years, along with the rapid increase dinosaurology data and
the quick fusion of data science and paleontology, various types of dinosaur-related databases have been constructed worldwide. Those
databases serve for different purposes. Some mainly contain introductions for the aim of popular science, some are built for specific research targets and others are comprehensive paleontological database containing dinosaur data. Because none of them is a professional dinosaur database, common defects such as incomplete data coverage and poor data structure, could be found and none has long-term sustainability. With the help of the Deep-time Digital Earth (DDE) big science project, to construct a professional dinosaur database combining the purposes of scientific research and popular science, can promote both the dinosaur evolution study and the public understanding for paleontology.

Key words: dinosaurology, database, evolution, popular science
