Dinosauriergruppen

Dinosauriergruppen refers to the classification of dinosaurs into distinct groups based on shared characteristics. The most fundamental division is between Saurischia, or "lizard-hipped" dinosaurs, and Ornithischia, or "bird-hipped" dinosaurs. This distinction is based on the structure of their pelvic bones. Saurischia includes theropods, like Tyrannosaurus Rex and Velociraptor, which were predominantly carnivorous bipedal dinosaurs, and sauropods, the long-necked, herbivorous giants such as Brontosaurus. Ornithischia encompasses a diverse range of herbivorous dinosaurs, including ornithopods, stegosaurs, ankylosaurs, and ceratopsians.

Within these two major groups, further subdivisions are made based on more specific anatomical features. For instance, theropods are categorized into groups like coelurosaurs and carnosaurs. Sauropods are divided into groups like diplodocids and macronarians. Ornithopods are broadly classified into iguanodontians and hadrosaurids (duck-billed dinosaurs). The study of these dinosauriergruppen allows paleontologists to understand evolutionary relationships, ecological roles, and the vast diversity of dinosaur life that existed during the Mesozoic Era. This systematic grouping is crucial for organizing fossil discoveries and for reconstructing the history of dinosaur evolution.
