There are no specific records of the birth of the first dinosaur, as dinosaurs originated in the Triassic period, approximately 230 million years ago. Based on the study of dinosaur fossils, scientists speculate that dinosaurs likely originated on the landmass between present-day Antarctica and South America. Based on paleontological research, most scientists believe that dinosaurs evolved from ancient reptiles, with their origins traced back to scaly reptiles.
Over millions of years, numerous different species and sizes of dinosaurs emerged during their evolution. Early dinosaur species, such as sauropods and carnivores, reached their peak during the Jurassic and Cretaceous periods.
Understanding the origin and evolution of dinosaurs is an ongoing scientific endeavor, and our understanding of dinosaurs is constantly being updated and enriched based on the ever-discovering fossils. Scientists continuously explore and infer the origin and development of dinosaurs through the study of paleontology, geology, biology, and related disciplines.
Although we have not yet found concrete evidence of how the first dinosaur came into being, we can infer a great deal of information about the origin of dinosaurs by studying the fossil record and by understanding extant reptiles and birds.
