Here's why:
* Immense and Ever-Growing: The number of fossils discovered is vast and constantly increasing as new sites are explored and new techniques are developed.
* No Centralized Database: There isn't a comprehensive, centralized database that catalogs every fossil find.
* Classification by Categories: Fossils are typically categorized by type (e.g., dinosaur fossils, plant fossils, trilobite fossils), geological time period, or geographical location.
So, while there's no single name for the entire collection, researchers and paleontologists work with specific sets of fossils based on their area of expertise and research interests.
