How many species lived during the triassic period 225 million years ago?

During the Triassic period, which lasted from about 252 to 201 million years ago, a diverse array of species existed, including early dinosaurs, marine reptiles, and various plants. However, specific estimates of the number of species are challenging due to the incomplete fossil record. It is believed that the Triassic saw the emergence of many new species following the mass extinction at the end of the Permian, but exact numbers remain uncertain. Overall, the period marked a significant diversification of life forms, setting the stage for the dominance of dinosaurs in the subsequent Jurassic period.
