There is no specific record of the birth of the first dinosaur, because dinosaurs originated in the Triassic period about 230 million years ago. Based on scientists' studies of dinosaur fossils, they speculate that the origin of dinosaurs likely occurred on the land between today's Antarctica and South America. Based on the study of ancient biology, most scientists believe that dinosaurs evolved from ancient reptiles, and their origins can be traced back to squamous reptiles.
During the evolution of dinosaurs, over millions of years, a large number of dinosaurs of different types and sizes appeared. Previous dinosaur species such as sauropods and carnivorous dinosaurs 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 will continue to be updated and enriched based on the continued discovery of fossils. Scientists continue to explore and infer the origin and development of dinosaurs by studying paleontology, geology, biology and related disciplines.
Although we have yet to find concrete evidence of how the first dinosaurs were born, we can infer a lot about their origins through the study of the fossil record and our understanding of living reptiles and birds.
