What was the environment compared to the present in the cretaceous?
The climate of the Cretaceous period was warmer and more humid than it is today. The Earth's landmasses changed during the Cretaceous and sea level was higher then than it is today.
What is the environment like in the Jurassic period compared to the present?
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.
What was the environment like in the cretaceous compared to today?
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.
During which era did the mosasaur swim in the interior seaway?
probably during the early part of the Cretaceous Period
What was the the environment like during the cretaceous period?
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.
What epoch did the T.Rex live in?
CRETACEOUS PERIOD144-65 Million Years Agoand in the really really really REALLY late jurassicbut mostly cretaceous
Animals during cretaceous period?
Some animals during the cretaceous period were tapejara, microraptor, and velociraptor. There was also triceratops, styracosaurus, and the tyrannosaurus rex.
Did T-rex appeared during the early Cretaceous?
Yes, T-Rex appeared during the beginning of Cretaceous about 137 million years ago.
What was the carboniferous environment like compared to the present?
During the Carboniferous period, the environment was warm and humid, with vast swamp forests covering much of the land. These forests eventually formed the coal deposits we see today. In contrast, the present environment is cooler and drier overall, with different vegetation and ecosystems in place.
What was the dominant land animal during the Jurassic and cretaceous period?
The dinosaurs were the dominant land animals during the Jurassic and Cretaceous periods, rising to dominance during the late Triassic.
What was the precambrian environment like compared to the present?
During the Precambrian period, which lasted from about 4.6 billion years ago to 541 million years ago, the Earth's environment was very different from the present. The atmosphere had little to no oxygen, the continents were still forming, and life was mostly single-celled organisms. The present environment is characterized by a more oxygen-rich atmosphere, complex multicellular life forms, and well-established continents.
What Era did dinosaurs live in?
The dinosaurs lived in the Mesozoic Era, which includes the Triassic, Jurassic, and Cretaceous periods. The first dinosaurs appeared in the late Triassic and went extinct at the end of the Cretaceous.
