Exempel på hur man kan använda ABELISAURID i en mening

• The femur possesses many primitive characteristics that have classified Cryolophosaurus as a dilophosaurid or a neotheropod outside of Dilophosauridae and Averostra, whereas the skull has many advanced features, leading the genus to be considered a tetanuran, an abelisaurid, a ceratosaur and even an allosaurid.
• Rugops (meaning ‘wrinkle face’) is a monospecific genus of basal abelisaurid theropod dinosaur from Niger that lived during the Late Cretaceous period (Cenomanian stage, ~95 Ma) in what is now the Echkar Formation.
• It was then seen as the only known abelisaurid from the Northern Hemisphere apart from Betasuchus of the Maastrichtian of the Netherlands but since then more species of abelisaurids have been found in the northern hemisphere.
• Other ceratosaurs such as the abelisaurid Rajasaurus, Rahiolisaurus and Indosuchus are known from the formation, along with the noasaurid Laevisuchus.
• It lived in a forested, riverine environment alongside the iguanodonts Elrhazosaurus and Ouranosaurus, the sauropod Nigersaurus, an undescribed titanosaurid, the spinosaurid Suchomimus, the carcharodontosaurid Eocarcharia, the abelisaurid Kryptops, and an undescribed noasaurid.
• Animals found in the formation include frogs (including Beelzebufo ampinga), turtles, snakes, lizards, at least seven species of crocodyliforms (including species of Mahajangasuchus and Trematochampsa), abelisaurid theropods Majungasaurus, noasaurid Masiakasaurus, two types of titanosaurian sauropods (Rapetosaurus and Vahiny), and at least five species of bird-like dinosaurs, including Rahonavis.
• An abelisaurid similar to Arcovenator is known from Département des Bouches-du-Rhone, while enantiornithean and indeterminate avialan remains are known from Département du Var.
• It coexisted with large predators like abelisaurid theropods, herbivores such as ankylosaurians and titanosaurian sauropods, as well as pterosaurs, crocodylomorphs, turtles, fish, and various archaic birds.
• Motta and colleagues recognized that this abelisaurid, along with a coelurosaur and carcharodontosaurid, present distinct traits (autapomorphies) from other Huincul Formation theropods.
• Dinosaurs are rare, however, including the large abelisaurid Chenanisaurus barbaricus, two other potentially distinct abelisaurids of smaller size, and an unnamed titanosaurian.
• Thanatosdrakon was contemporaneous with an indeterminate abelisaurid, basal coelurosaurian, unenlagiine, aeolosaurin, saltasaurid, and ornithopod, Non-dinosaurian taxa from the formation include freshwater bivalves, an indeterminate crocodyliforme and mesoeucrocodylian, the chelid turtles Linderochelys and Rionegrochelys, and at least one indeterminate mammal.
• It coexisted alongside other dinosaurs, such as the abelisaurid theropod Thanos simonattoi and a larger, unnamed probable megaraptoran, as well as an indeterminate notosuchian.
• The Barda Atravesada de Las Campanas locality from which Campananeyen was recovered has also yielded partial skeletal remains of another rebbachisaurid, a small unnamed abelisaurid, a chelid turtle, and.
