Jurellana tithonia n. sp. is the earliest known Porcellanidae, from the Tithonian Ernstbrunn Limestone, Austria. Porcellanids are well-known from the fossil record, already having been described from Cretaceous, Eocene, and Neogene rocks. Their occurrence in the Jurassic is not surprising, because the Infraorder Anomura, to which they belong, is the sister to the Brachyura, well known from Jurassic occurrences.
