The climate was generally hot and dry, forming typical red-bed sandstones and evaporites. There is no evidence of glaciation at or near either pole; in fact, the polar regions were apparently moist and temperate, a climate suitable for reptile-like creatures. Pangaea's large size limited the moderating effect of the global ocean; it's continental climate was highly seasonal, with very hot summers and very cold winters. It probably had strong cross-equatorial monsoons.

What were five living things from the Triassic period?
During the Triassic period, which lasted from about 252 to 201 million years ago, five notable living things included the early dinosaurs, such as Eoraptor, the marine reptile Nothosaurus, the archosaur Pseudosuchia, the plant Lepidopteris, and the first mammals, like Morganucodon. This period marked significant evolutionary developments, including the rise of dinosaurs and the diversification of early reptiles and mammals. The Triassic ecosystems were characterized by a mix of terrestrial and marine life, reflecting the aftermath of the Permian-Triassic extinction event.
What period did the first dinosaur's appear in?
The earliest reptiles known evolved around 312 million years ago, and looked a lot like lizards. However, they were not actually lizards. The oldest known lizard fossil dates to 220 million years ago, about the same time that dinosaurs evolved. That was during the Triassic period of the Mesozoic era.
How are the Triassic and Jurassic periods similar to the Permian and Triassic periods?
The Triassic and Jurassic periods, like the Permian and Triassic periods, are characterized by significant geological and biological developments. Both pairs mark transitions between major eras, with the Triassic serving as a bridge between the Paleozoic and Mesozoic eras. Additionally, each period experienced notable shifts in biodiversity, including the rise of dominant reptilian groups in the Triassic and Jurassic, paralleling the recovery and diversification of life following the Permian-Triassic extinction event. Both periods also witness substantial climatic changes that influenced terrestrial and marine ecosystems.
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.
When did the first primitive mammals appear in the fossil record in what period?
The first primitive mammals appeared in the fossil record during the Late Triassic period, approximately 225 million years ago. These early mammals were small, shrew-like creatures that lived alongside dinosaurs. The emergence of mammals marked a significant evolutionary development, leading to the diverse range of species we see today.
Index fossils during triassic period?
Some index fossils during the Triassic period include ammonites, conodonts, and certain marine reptiles like nothosaurs and thalattosaurs. These fossils are used by paleontologists to help date and correlate rock layers from that time period. They provide important information about the environments and life forms of the Triassic era.
What was the Triassic Period's environment like compared to the present?
it was mostly covered with trees and grass.
What was the world like in the Triassic period?
Hot and dry
What are socket-tooth reptiles that lived in the Triassic Period?
Socket-tooth reptiles, also known as phytosaurs, were ancient reptiles that lived during the Triassic Period. They had long, slender skulls with socket-like depressions for their teeth, which resemble those of modern crocodiles. Phytosaurs were semi-aquatic predators that roamed both land and water during the Triassic.
What was the environment like during the Miocene period?
k
What was the environment like during the Jurassic period?
Warmer climate

What was the environment like at the time lystrosaurus lived?
Lystrosaurus lived during the Early Triassic period, approximately 250 million years ago, in a post-Permian environment characterized by a recovery from the Permian-Triassic extinction event. The climate was predominantly dry and arid, with some regions featuring seasonal rain, leading to a mix of open plains and sparse vegetation. Lystrosaurus thrived in this environment as a herbivorous synapsid, adapting to the harsh conditions with its burrowing lifestyle, which provided shelter from extreme temperatures and predators.
What kind of mammals were on earth during dinosaur ages?
During the end of the Triassic period, the first mammals evolved from therapsids, or mammal like reptiles. Some of these mammals were the Purgatorius, a tiny rodent like creature, and the Castorocauda, which had beaver like characteristics.
How was the environment like during the Cretaceous period compared to the present?
grassy and naked
What was the environment like during the tertiary time period?
The environment was covered with trees and grass, and the air was warm and moist.
