# Paleobiota of the Kristianstad Basin

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 (c.  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 (c.  86.3 million years ago) to the early Maastrichtian (c.  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.

| Group | Sites | Age | Material | Notes | Images |
| Leptoceratopsidae indet. | Åsen, Ullstorp | Earliest Campanian – latest Early Campanian | Four maxillary teeth, a dentary tooth, two caudal vertebrae, one right manual phalanx | Morphology of the teeth recovered corresponds roughly to Leptoceratops. Given that the teeth lack some of the ridges present in the teeth of Leptoceratops, and because of geographical distance, the Åsen leptoceratopsid is likely a new taxon. | A leptoceratopsid dinosaur (Leptoceratops) A theropod dinosaur (Australovenator) |
| Ornithopoda indet. 1 | Åsen | Latest Early Campanian | A left pedal phalanx | A small ornithopod dinosaur. The recovered phalanx resembles the same bone in Thescelosaurus assiniboiensis. | A leptoceratopsid dinosaur (Leptoceratops) A theropod dinosaur (Australovenator) |
| Ornithopoda indet. 2 | Åsen | Latest Early Campanian | A left pedal phalanx | A small ornithopod dinosaur. The recovered phalanx resembles the same bone in Hypsilophodon foxii. | A leptoceratopsid dinosaur (Leptoceratops) A theropod dinosaur (Australovenator) |
| Theropoda indet. | Ugnsmunnarna | Latest Early Campanian | An incomplete right tibia | Identified as the remains of a small theropod dinosaur after comparisons with the same bone in the Australian genus Australovenator. The bone structure confidently identifies the fossil as that of a non-avian theropod dinosaur. | A leptoceratopsid dinosaur (Leptoceratops) A theropod dinosaur (Australovenator) |

The quadrate is from a younger (Maastrichtian) layer than the other mosasaurs. | Clidastes Hainosaurus Mosasaurus Platecarpus Prognathodon Tylosaurus |
| Prognathodon | P. sp. | Ivö Klack, Åsen | Latest Early Campanian | Isolated teeth, fragments of a jawbone, vertebrae | A mosasaur at about 8 meters in length with relatively wide and deep jaws. Bite marks matching Prognathodon teeth have been found on plesiosaur bones in the Kristianstad Basin.

Scanisaurus is no longer considered a valid taxon, but the name continues to be used for practical purposes. S. nazarowi is the type species of Scanisaurus and was previously referred to Cimoliasaurus. | Elasmosaurus A polycotylid plesiosaur (Trinacromerum) |
| Scanisaurus | S. sp. | Ignaberga, Åsen | Latest Early Campanian – early Late Campanian | A crushed skull, isolated teeth | Fossils of this species include the only plesiosaurian skull (albeit crushed) known from Sweden.
