Every month, 100,000 readers use the Dinosaur Database, but we receive no support from you. Developing and updating the database requires a lot of work. Therefore, as of September 1, 2025, the database will be closed. If you want it to remain open and be updated, please support us via the "Buy us a coffee" button available on every page.
