Extinct Groups of Reptilia
Extinct groups of Reptilia are:
- Ichthyopterygia: Ichthyopterygia is an extinct order of marine reptiles which lived during the mesozoic era. Ichthyopterygia resembled dolphins
- Archosauria: Archosauria were also known as ruling reptiles. They were the major group of diapsids. They are represented today only by crocodilians and birds
- Lepidosauria: Lepidosauria are ancestors of Squamata and the extant rhynchocephalian. The common features are overlapping scale and are also characterised by their scaly skin.
- Synapsida: Synapsids were the largest terrestrial vertebrates in the Permian period. A subclass of reptiles which includes the Pelycosauria and Therapsida.
Reptilia: Definition, Characteristics, Classification, and Example
Reptilia is a group of vertebrates that includes animals such as lizards, alligators, tortoises, turtles, crocodiles, and snakes. Animals of the class Reptilia are known as Reptiles. Reptilia can be found in various regions such as forests, deserts, freshwater, wetlands, and mangroves. They are cold-blooded animals and their skin is covered with scales.
The Mesozoic Era was the “Golden Age of Reptiles.” The study of snakes is known as Serpentology or Ophiology. They are mostly terrestrial and tetrapods. Reptilia is divided into anapsida, parapsida and diapsida. Reptilia has both ecological and economic importance.
