Lissamphibia - Wikipedia
The Lissamphibia (from Greek λισσός (lissós, "smooth") + ἀμφίβια (amphíbia), meaning "smooth amphibians") is a group of tetrapods that includes all modern amphibians.Lissamphibians consist of three living groups: the Salientia (frogs, toads, and their extinct relatives), the Caudata (salamanders, newts, and their extinct relatives), and the Gymnophiona (the limbless caecilians ...
The origins of Lissamphibia - Peer Community In
Within Lissamphibia, most studies place frogs and salamanders in a clade together to the exclusion of caecilians (see Pyron & Wiens 2011). Among fossils, there are a number of amphibian and amphibian-like taxa generally placed in Temnospondyli and Lepospondyli. In contrast to the tree of living tetrapods, affinities of these fossils to some or ...

Other articles where lissamphibian is discussed: amphibian: …three orders make up subclass Lissamphibia. Neither the lissamphibians nor any of the extinct groups of amphibians were the ancestors of the group of tetrapods that gave rise to reptiles. Though some aspects of the biology and anatomy of the various amphibian groups might demonstrate features possessed by …
On the origin of and phylogenetic relationships among living …
2001年6月6日 · Living amphibians (Lissamphibia) are highly successful tetrapods that evolved diverse body plans that differ in modes of locomotion, reproductive specializations, and life histories (1, 2).For instance, the slender body of living salamanders (Caudata) has a well developed tail and proportionally paired limbs, whereas modern caecilians (Gymnophiona) are completely limbless, and are adapted to a ...
Braincase simplification and the origin of lissamphibians
2019年3月22日 · A comparison between the braincases of the extinct tetrapod Eryops (A, B) and the extant salamander Hynobius (C, D), in lateral (A, C) and occipital (B, D) views, summarizing the main differences between lissamphibian braincase composition and morphology and that of other tetrapods. The sphenethmoid is purple, the basioccipital is blue, the basisphenoid is red, the exoccipitals are green, the ...
Fossils, Molecules, Divergence Times, and the Origin of …
2007年6月1日 · A review of the paleontological literature shows that the early dates of appearance of Lissamphibia recently inferred from molecular data do not favor an origin of extant amphibians from temnospondyls, contrary to recent claims. A supertree is assembled using new Mesquite modules that allow extinct taxa to be incorporated into a time-calibrated ...

2024年10月25日 · The Lissamphibia is a well-corroborated monophyletic group containing all the living orders of amphibians. However, the exact placement of the Lissamphibia within an overall classification of the Amphibia remains uncertain, although evidence continues to grow for them as members of the temnospondyl clade. Within the Lissamphibia, there are two ...
Focal Review: The Origin (s) of Modern Amphibians - Springer
2008年11月12日 · The recent description of the stem batrachian Gerobatrachus has changed the terms of the ongoing debate on the origin of extant amphibians (Lissamphibia: frogs, salamanders, and the limbless caecilians). This important fossil, through a shared mosaic of unique derived salientian and urodele characters, links frogs and salamanders with an archaic group of fossil amphibians known as amphibamid ...
Amphibians (Lissamphibia) | The Timetree of Life - Oxford Academic
Lissamphibia, a subclass of Amphibia, includes all living representatives, which form three clades, frogs (Salientia), salamanders (Caudata), and caecilians (Gymnophiona), each readily recognizable based on their highly distinctive body plans (Fig. 1). Frogs generally have large mouths and bulging eyes, but short vertebral columns and no tail ...
