Around 470 million years ago, during the Ordovician period, one of the dominant predatory organisms was the nautiloid cephalopod, particularly species like Cameroceras. These creatures had elongated, coiled shells and were effective predators in the ancient seas, preying on smaller marine animals. Additionally, early vertebrates such as jawless fish may have also played a significant role in the predatory dynamics of the time.

Around 470 million years ago, during the Ordovician period, arthropods were among the dominant marine organisms. This era saw the emergence of early forms of trilobites, which were abundant and diverse, showcasing a variety of shapes and sizes. Other arthropods, such as primitive crustaceans and possibly the first arachnids, also began to appear during this time, marking significant evolutionary advancements in this phylum. These creatures played a crucial role in the marine ecosystems of the period.

Mosses evolved first among these groups, appearing around 470 million years ago. They were followed by ferns, which emerged roughly 360 million years ago. Gymnosperms, such as conifers, appeared next around 319 million years ago, and angiosperms, or flowering plants, evolved later, approximately 140 million years ago. Thus, the correct order of evolution is mosses, ferns, gymnosperms, and then angiosperms.
