The Kristianstad Basin is a Cretaceous-age structural basin and geological formation in northeastern Skåne, the southernmost province of Sweden. The sediments in the basin preserves a wide assortment of taxa represented in its fossil record, including the only non-avian dinosaur fossils in Sweden and one of the world's most diverse mosasaur faunas.

Though a majority of the taxa listed below lived during the latest early Campanian ( 80.5 million years ago; fossils from the site Ivö Klack alone from this time compromise about 40 vertebrate species and more than 200 invertebrate species), the Kristianstad Basin preserves fossils ranging in age from the early Santonian ( 86.3 million years ago) to the early Maastrichtian ( 72.1 million years ago); some of the animals in the list were not contemporaries, but separated from each other in time by several million years. The time spans from which fossils have been recovered is included for each species in the list.
