PAL SYS is an online reference resource focused on the classification and literature of genera, with extensive coverage of dinoflagellate cysts and other fossil and living micro-organisms. Its genus catalogue presents names alongside the authors and publication details associated with their original descriptions, helping users trace taxonomic names to the scientific literature. Visitors can browse the genera, filter listings by age range in millions of years, and narrow results by morphology, including whether a genus is a dinocyst.

The interface also offers options to hide inactive genera and reset filters. PAL SYS provides informational sections about the project and its subject matter, as well as registration and login features. A contribution option indicates that users can participate in the resource.

The available catalogue spans a broad range of genera, from Abantosphaeridium and Acanthaulax to Ceratiopsis and Cristadinium, and includes entries attributed to researchers across many decades. PAL SYS serves as a searchable starting point for exploring genus names and their taxonomic publication history
