Funcusvermis is an extinct genus of stem-caecilian from the Late Triassic of Arizona.It is based on a large sample of jaws and other skull and postcranial fragments, discovered in an approximately 220 million years old layer of rock in the Blue Mesa Member of the Chinle Formation at Petrified Forest National Park.
There is a tentacle about halfway between eye and nostril. The lower jaw has only one row of teeth. [4] Living specimens are very dark purple to purple-black above and creamy white below. [1] Based on external morphology, three groups of species can be recognized: [4] large caecilians with numerous secondary folds: D. mexicanus and D. oaxacae
Caecilians are some of the least studied amphibians. Not much is known about their behavior and life history. Siphonops annulatus is highly fossorial, spending most of its life burrowed underground. A study found tunnels made by this species to go no deeper than 20 cm. This species uses a highly ossified skull to help burrow into the ground. [5]
Named Funcusvermis gilmorei, it lived at the beginning of the age of the dinosaurs
