Batrachology is the branch of zoology concerned with the study of amphibians including frogs, salamanders, and caecilians. It is a sub-discipline of herpetology, [1] which also includes non-avian reptiles (snakes, lizards, turtles, crocodilians, and the tuatara). Batrachologists may study the evolution, ecology, ethology, or anatomy of amphibians.
If two or more genera are formally designated and the type specimens are later assigned to the same genus, the first to be published (in chronological order) is the senior synonym, and all other instances are junior synonyms. Senior synonyms are generally used, except by special decision of the ICZN, but junior synonyms cannot be used again ...
Michael Benton adopted the term Batrachomorpha to include all living amphibians and extinct relatives more closely related to amphibians than to amniotes. In his scheme, Batrachomorpha is a superorder of amphibious tetrapods containing the following subgroups: [6] Superorder Batrachomorpha †Order Edopoidea †Family Dendrerpetonidae; Order ...
Evidence from the study of brain endocasts of extant and extinct mammals, indicative of cortical expansion in the areas of the brain involved in producing cognitive functions that began early on during the primate evolution, is presented by Melchionna et al. (2025), who argue that selection for complex cognition likely drove the evolution of primate brains.
The largest living amphibian is the 1.8 m (5 ft 11 in) South China giant salamander (Andrias sligoi), but this is dwarfed by prehistoric temnospondyls such as Mastodonsaurus which could reach up to 6 m (20 ft) in length. The study of amphibians is called batrachology, while the study of both reptiles and amphibians is called herpetology.
Slight increase in diversity of cold-tolerant ostracods and foraminifers, along with major extinctions of gastropods, reptiles, amphibians, and multituberculate mammals. Many modern mammal groups begin to appear: first glyptodonts, ground sloths, canids, peccaries, and the first eagles and hawks. Diversity in toothed and baleen whales. 33 Ma
Mammalogy has also been known as "mastology," "theriology," and "therology." There are about 4,200 different species of animals which are considered mammals. Cetology – branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoise in the scientific order Cetacea.
The evolution of tetrapods began about 400 million years ago in the Devonian Period with the earliest tetrapods evolved from lobe-finned fishes. [1] Tetrapods (under the apomorphy-based definition used on this page) are categorized as animals in the biological superclass Tetrapoda, which includes all living and extinct amphibians, reptiles, birds, and mammals.
