<start_of_turn>model
A wide variety of dinosaur species have been identified and classified over time, but estimating the exact number of dinosaur types can be an ever-evolving challenge due to new research and discoveries. Although a precise and definitive number cannot be provided, it is estimated that around 1,000 different genera of dinosaurs have been described and cataloged to date.

Dinosaurs varied in size, shape, diet and habitat. They are grouped into several main categories based on their characteristics, and are classified into two main groups: Saurischia (reptile-hipped) and Ornithischia (bird-hipped).

Each group is divided into subgroups and then into genera and species. Some of the best-known dinosaur genera and species include:

- Theropods: This group includes famous predators such as Tyrannosaurus rex and Velociraptor.

- Sauropods: Sauropods were long-necked herbivorous dinosaurs, like Brachiosaurus and Diplodocus.

- Ornithopods: These herbivores include iguanodonts and hadrosaurs, such as Parasaurolophus.

- Marginocephalians: This group includes the ceratopsians, which had horns and ornamental structures, like Triceratops.

- Feathered theropods: It has been discovered that some theropods had feathers, which relates them to modern birds. Examples include Archeopteryx.

It should be noted that the classification of dinosaurs continues to be the subject of research and debate in the scientific community. New fossils and genetic analyzes continue to shed light on the diversity and relationship between different dinosaur species. As more fossil remains are discovered and research techniques are refined, our understanding of the variety of dinosaur types will continue to evolve.<end_of_turn><eos>
