The Albanerpetontidae (also spelled Albanerpetidae and Albanerpetonidae) are an extinct family of small amphibians, native to the Northern Hemisphere during the Mesozoic and Cenozoic. The only members of the order Allocaudata, they are thought to be allied with living amphibians belonging to Lissamphibia. Despite a superficially salamander-like ...
The common mudpuppy can be a rusty brown color with gray and black and usually has blackish-blue spots, but some albino adults have been reported in Arkansas. [6] In clear, light water, their skin gets darker, likewise in darker water, their skin gets lighter in color. [5]
They are most active in cold temperatures, specifically between 9.1 and 20.2 degrees Celsius. [16] [17] During the day, N. maculosus seeks refuge under rocks or logs and plant debris. [15] They forage during the night and eat a variety of prey, but have preference for crayfish. [4] During the winter and spring, N. maculosus will also eat fish. [5]
Trematosauroidea are an important group of Triassic temnospondyl amphibians. They flourished briefly during the Early Triassic, occurring worldwide before declining at the start of the Middle Triassic, although the group continued until the Late Triassic. They were medium-sized temnospondyls with wedge-shaped tails, narrow skulls, and, in ...
Amphisbaenia / æ m f ɪ s ˈ b iː n i ə / (called amphisbaenians or worm lizards) is a group of typically legless lizards, [2] comprising over 200 extant species. Amphisbaenians are characterized by their long bodies, the reduction or loss of the limbs, and rudimentary eyes.

The origins and evolutionary relationships between the three main groups of amphibians are hotly debated. A molecular phylogeny based on rDNA analysis dating from 2005 suggests that salamanders and caecilians are more closely related to each other than they are to frogs, and the divergence of the three groups took place in the Paleozoic or early Mesozoic before the breakup of the ...
