The common consensus is that dinosaurs dominated the land, being the most diverse large animals, and reaching huge sizes. In the oceans, large marine creatures included plesiosaurs, pliosaurs, ichthyosaurs (during the Jurassic and early Cretaceous), and mosasaurs (during the Cretaceous). The skies were ruled by pterosaurs. Coniferous trees were the primary large plants.
Reptiles were the primary large animals during the Cretaceous period. On land, there were dinosaurs, in the air were pterosaurs, and the oceans were inhabited by plesiosaurs and mosasaurs.

Early Paleozoic is pretty long time, so you have to be more specific about that. Probably one of the most dominant creatures that ever evolved was Anomalocaris (from Cambrian period). Most of the animals from that time couple of inches long, while Anomalocaris was 2 meters long. Also giant scorpions, like world famous Jaekelopterus rhenaniae were also top predators of it's days.
The dinosaurs were the dominant land animals during the Jurassic and Cretaceous periods, rising to dominance during the late Triassic.
Dinosaurs first appeared during the Triassic period, approximately 230 million years ago. They became the dominant terrestrial vertebrates throughout the Jurassic and Cretaceous periods, which lasted until about 66 million years ago. Their emergence marked a significant evolutionary milestone, leading to a diverse range of species that adapted to various environments.
None-avian dinosaurs first appeared in the Triassic period and were the dominant land vertebrates through the Jurassic and Cretaceous periods. At the end of the Cretaceous period, 65.5 million years ago, all non-avian dinosaurs went extinct. Birds, which are now classified as dinosaurs, continue to live to his day.
I know that the angiosperms were most dominant during the cretaceous period but im not too sure about the dinosaurs dominant era. I would assume they were both dominant in the same era but I am not 100% sure.Read more: http://wiki.answers.com/Dinosaurs_and_angiosperms_were_dominant_lineages_during_with_geologic_era#ixzz1G5bqBpQR
The Cretaceous period followed the Jurassic period and lasted from about 145 million to 66 million years ago. In the Cretaceous period, flowering plants became more dominant, dinosaurs continued to diversify, and large marine reptiles like mosasaurs thrived. However, the end of the Cretaceous period marked by a mass extinction event where dinosaurs and many other species went extinct.
It was a warm tropical place in which many angiosperms (flowering plants) developed and became dominant. Because of this, many new herbivores appeared and others went extinct.The Cretaceous Period was hot and dry.
They were dominant during the mesozoic era, which was made up of the Triassic, Jurassic, and Cretaceous periods.
I know that the angiosperms were most dominant during the cretaceous period but im not too sure about the dinosaurs dominant era. I would assume they were both dominant in the same era but I am not 100% sure.
