Fossils and Geological Eras

Carboniferous period marked the formation of coral beds.

The earth originated during this time period.

Paleontology is the scientific study of fossils. Organic evolution is the process. Palaeogeography studies ancient geography. Herpetology studies reptiles and amphibians. Fossils provide crucial evidence for evolution and help reconstruct ancient life forms and environments.

 The dinosaurs and the mammals appeared during the Triassic period, roughly 225 million years ago. The dinosaurs went extinct 65 million years ago. The Mesozoic Era lasted about 180 million years, and is divided into three periods, the Triassic, the Jurassic and the Cretaceous.

The earliest evidence of land plants dates to the Ordovician period (485-444 million years ago), which is part of the Paleozoic era. This marks the transition from aquatic to terrestrial plant life.

Paleontology is the scientific study of fossils and what they reveal about ancient life forms, their evolution, and Earth's geological history. The word itself derives from Greek meaning 'ancient being study'.

Teeth are the most durable part of vertebrate remains due to their high mineral content (enamel and dentine). Unlike soft organs like heart, skin, or liver, teeth resist decay and fossilize readily.

Eocene epoch was the warmest period during cenozoic era.

Permian period represents ‘Age of Amphibians’, well dominated by various amphibians.

 The ‘Age of trilobites’ has been attributed to the Cambrian period. The Cambrian period is famous for Cambrian explosion when major groups of animals appeared in the fossil record in a relatively brief phase of time leading to diversification on a large scale.

In terms of evolution, Merychippus was the first three-toed grazer fossil of the horse; the central toe bore the most of the body weight.

The evolutionary history of the horse depicts a good example of Cope's rule that states that the animals tend to increase in body size during the course of evolution.

The Permian period was the most recent period of the Paleozoic era.

yes, fossils tell us very much about the animal species.

Statement (1) is incorrect. Most dinosaurs became extinct in Crustacean period. Statement (2) is correct. Yes, a mango has dicot (two cotyledons) seed.
