The earliest known true snake fossils (members of the crown group Serpentes) come from the marine simoliophiids, the oldest of which is the Late Cretaceous (Cenomanian age) Haasiophis terrasanctus from the West Bank, [1] dated to between 112 and 94 million years old. [25] Based on genomic analysis it is certain that snakes descend from lizards ...
Reptiles, from Nouveau Larousse Illustré, 1897–1904, notice the inclusion of amphibians (below the crocodiles). In the 13th century, the category of reptile was recognized in Europe as consisting of a miscellany of egg-laying creatures, including "snakes, various fantastic monsters, lizards, assorted amphibians, and worms", as recorded by Beauvais in his Mirror of Nature.

There are over 6700 species of amphibians [9] and over 9000 species of reptiles. [10] Despite its modern taxonomic irrelevance, the term has persisted, particularly in the names of herpetology, the scientific study of non-avian reptiles and amphibians, and herpetoculture, the captive care and breeding of reptiles and amphibians.
Calling all budding herpetologists! These are the best types of reptiles you can keep as a pet
A recently described sphenodontian reptile is one of the oldest known herbivorous lepidosaurs. This animal possesses a number of features that demonstrate an herbivorous lifestyle, such as a specialized jaw movement (propalinal) and closely packed teeth that appear to be useful in the shearing of plant material.

One of the best known early reptiles is Mesosaurus, a genus from the Early Permian that had returned to water, feeding on fish. The earliest reptiles were largely overshadowed by bigger labyrinthodont amphibians, such as Cochleosaurus, and remained a small, inconspicuous part of the fauna until after the small ice age at the end of the ...
These amphibians are illegal to own in some US states, including California, Maine, New Jersey, and Washington D.C, for one main reason: the threat they pose to the already struggling native ...
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
