HOMO SAPIENS were so the dominent speices
Before dinosaurs, the Earth was primarily inhabited by earlier forms of life, including amphibians, reptiles, and various types of plants. The late Paleozoic era featured the dominance of amphibians, while the early Mesozoic era saw the rise of reptiles. The first true dinosaurs appeared during the Triassic period, evolving from earlier archosaurian reptiles. Additionally, the Permian period, which preceded the Mesozoic, was marked by the diversification of life forms leading up to the age of dinosaurs.
European feudalism emerged when the Roman empire fell during the 5th century. During the 10th century, it was in France and Germany that the first elements of feudalism appeared.
Insects first appeared around 480 million years ago during the Ordovician period. Fossil evidence suggests that they evolved from primitive arthropods and became abundant in terrestrial environments by the Devonian period, roughly 400 million years ago. Their diversification has continued ever since, making them one of the most successful groups of organisms on Earth.
The Dallas Cowboy Cheerleaders first appeared during the 1972-1973 NFL season.
bacteria
Pterosaurs
Multicellular organisms first appeared during the Vendian period.
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.
The mammals.
Flowering plants first appeared around 140 million years ago during the Cretaceous period. They rapidly diversified and became the dominant group of plants, replacing many of the existing groups at the time.
It's easy: the first dinosaurs and the first bugs were alive during the Mesozoic ere.
No. The 1st vertebrates appeared in the fossil record about 525 million years ago during the Cambrian Period. This was in the Paleozoic Era.
the first type of life form that appeared in the mesozoic era was a fish! the second type of life form that appeared in the mesozoic era was the reptile! and the third was a reptile bird!!!!!!!!!!!!!!!!
Dinosaurs first appeared around 230 million years ago, during the Triassic period. This was part of the Mesozoic era, which covered almost all of dinosaur existence.
The first dinosaurs lived in the beginning of the Mesozoic Era (or the Age of Reptiles). Birds were amazingly discovered to be dinosaurs so dinosaurs were also alive in the Cenozoic (that's our time-the Age of Mammals) to today.
Multicellular organisms first appeared during the Vendian period.
Dinosaurs first appeared in the early Mesozoic.
