Caecilians feed on small subterranean creatures such as earthworms. The body is cylindrical and often darkly coloured, and the skull is bullet-shaped and strongly built. Caecilian heads have several unique adaptations, including fused cranial and jaw bones, a two-part system of jaw muscles, and a chemosensory tentacle in front of the eye. The ...
Ymboirana was an extinct genus of caecilian described based on a fossil found in the Oligocene Tremembé Formation (Taubaté Basin), Brazil.The holotype and only known specimen comprises a partially preserved skeleton, including parts of the skull and vertebral column.
The features uniting the Lissamphibia were first noted by Ernst Haeckel, even though in Haeckel's work, Lissamphibia excluded the caecilians. [6] [11] Nevertheless, Haeckel considered the caecilians to be closely related to what he called Lissamphibia (gr. λισσός, smooth), which is now called Batrachia and includes frogs and salamanders.
Named Funcusvermis gilmorei, it lived at the beginning of the age of the dinosaurs
The rocks in which these fossils were discovered had been informally referred to as the "Clepsydrops shales", named after a local genus of early synapsid by Cope in 1865. The shales were initially believed to be from either the Permian or Triassic periods in age based on the purported presence of reptile and lungfish fossils. By 1878, Cope had ...
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]
Millions of prehistoric marine fossils were discovered beneath a California high school over the course of a multi-year construction project. The relics recovered at San Pedro High School included ...
B. taitana is an oviparous caecilian, and there is a parent-offspring transfer of nutrients after birth. B. taitana offsprings are born in an undeveloped state, thus requiring feeding and care by the parents. The dentition of offspring includes 'fetal-like' teeth, which they use to peel and eat the modified skin of their mothers after birth.
