Were dinosaurs r or k species?

Answer 1

Dinosaurs were a diverse group of reptiles that existed on Earth for a period of about 165 million years, from the Late Triassic period (approximately 230 million years ago) until the end of the Cretaceous period (about 65 million years ago). During this time, dinosaurs evolved into a wide range of sizes, shapes, and ecological niches.

The term "species" is used to describe distinct groups of organisms that can interbreed and produce fertile offspring. In the case of dinosaurs, scientists have identified and classified numerous species based on fossil evidence. Dinosaurs were not a single species but rather a large group of related species that varied in their characteristics.

Some well-known dinosaur species include Tyrannosaurus rex, Triceratops horridus, Stegosaurus stenops, and Velociraptor mongoliensis, among many others. These species had distinct anatomical features and occupied different habitats during their time on Earth.

It's important to note that the study of dinosaurs is an ongoing scientific field, and new discoveries are constantly being made. As our understanding of dinosaurs continues to evolve, the classification and identification of species may change based on new evidence and research
