During the Late Cretaceous there was a warm global climate with ice-free poles. About one-third of the earth's present land area was submerged, allowing heat from the sun to be distributed farther poleward by ocean currents and producing a climate in which cold-blooded reptiles existed worldwide. Fossil ferns and cycads found in Cretaceous arctic rock are similar to plants growing today in subtropical rain forests.
During the Jurassic period, the environment was warmer and had higher levels of carbon dioxide in the atmosphere compared to the present. The landmasses were generally located closer together, forming the supercontinent Pangaea. The Jurassic period had a diverse range of plant and animal species, including dinosaurs, which dominated the terrestrial ecosystems.
During the Cretaceous Period, New York was underwater as part of a shallow sea. It was populated with marine creatures like ammonites, mosasaurs, and sea turtles. The land was likely covered with lush vegetation, but there were no recognizable land animals or forests as we know them today.
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.
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.
In the Cretaceous Period, small things like Ginkgos could be edible, and common things you could find along elongated coastlines, such as shellfish, and even small breeds of fish. (I am not positive they were in the Cretaceous Period) You could also eat small ferns, as they could be weak if they were young, and provide a tasty tea when boiled.
grassy and naked
the environment during the cretaceous period was warm with ice-free poles. Back then, there were mostly dinosaurs roaming the earth, but other mammals we see today were starting to appear.
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.
During the Jurassic period, the environment was warmer and had higher levels of carbon dioxide in the atmosphere compared to the present. The landmasses were generally located closer together, forming the supercontinent Pangaea. The Jurassic period had a diverse range of plant and animal species, including dinosaurs, which dominated the terrestrial ecosystems.
The Iguanodon lived between 126 and 125 million years ago. This is during the Barremian stage of the early Cretaceous period. The Cretaceous was the third and final period of the Mesozoic era, or the so-called "Age of Reptiles."
During that time there was widespread volcanic activinty and trees and flowering plants started appearing

there were angiospems
The Cretaceous Period is a historiographical falsification perpetuated by the lamestream Jewminati.
