Reptiliomorpha (meaning reptile-shaped; in PhyloCode known as Pan-Amniota[2][3]) is a clade containing the amniotes and those tetrapods that share a more recent common ancestor with amniotes than with living amphibians (lissamphibians).

Reptiliomorpha is one stem from the tetrapod node by definition. The other stem really ought to be called something other than Lepospondyli, since we really don't know if the traditional lepospondyls included the ancestor of modern amphibians.

Reptiliomorpha is a clade of the amniotes and those tetrapods that share a more recent common ancestor with amniotes than with living amphibians (lissamphibians). Unfortunately, different experts have used the term in several different ways.

Reptiliomorpha is a name given either to reptile-like labyrinthodonts, or to amniotes and the amphibians from which they evolved. University of Bristol paleontologist Professor Michael J. Benton (2000, 2004) gives the following characteristics for the …

The real turn to terrestriality begins here, with the Reptiliomorpha. We tentatively define this clade as one of the supporting stems of crown group Tetrapoda* . As a reminder, Tetrapoda* is defined (at various places in Palaeos, as dogs + frogs, princes + frogs, or Prof. Michael Coates + frogs.

The Reptiliomorpha are the group of animals more closely related to modern amniotes (reptiles and mammals) than to modern batrachians (frogs and salamanders). As well as the amniotes themselves, reptiliomorphs include the Carboniferous and Permian 'anthracosaurs' and lepospondyls, two groups traditionally classed as amphibians.

A list of reptiliomorphs, (excluding amniotes), throughout their time.

Reptiliomorpha is a clade containing the amniotes and those tetrapods that share a more recent common ancestor with amniotes than with living amphibians (lissamphibians). The name Reptiliomorpha was coined by Professor Gunnar Säve-Söderbergh in 1934 to designate amniotes and various types of late Paleozoic tetrapods than were more closely ...

Even so, even basal members like Caerorhachis (Early Carboniferous - right) possess evolutionary novelties that characterize Reptiliomorpha: The elements of the skull roof and cheek are loosely connected in a mobile articulation.

Oct 22, 2020 · Reptiliomorpha is defined as including all tetrapods closer to Amniota (Synapsida+Sauropsida) than to Lissamphibia. As such, its composition has fluctuated over the decades but seems to include the amphibian-grade "anthracosaurs" while by definition excluding the modern amphibians & their stem lineage (i.e. Temnospondyli) and including the very ...

Reptiliomorpha is a clade of the amniotes and those tetrapods that share a more recent common ancestor with amniotes than with living amphibians (lissamphibians). Unfortunately, different experts have used the term in several different ways. It …

Reptiliomorpha (meaning reptile-shaped; in PhyloCode known as Pan-Amniota[2][3]) is a clade containing the amniotes and those tetrapods that share a more recent common ancestor with amniotes than with living amphibians (lissamphibians).

For practical reasons, these groups are referred to as “reptiliomorphs” in this study – in agreement with the temnospondyl hypothesis of lissamphibian ancestry.

While retaining a general build like those found in the amphibian reptiliomorph groups like Seymouriamorpha and Diadectomorpha, Casineria also shows features that tie it in with early reptiles, notably a generally gracile build with light leg …

Sep 27, 2024 · Reptiliomorpha is a clade containing the amniotes and those tetrapods that share a more recent common ancestor with amniotes than with living amphibians (lissamphibians). It was defined by Michel Laurin (2001) and Vallin and Laurin (2004) as the largest clade that includes Homo sapiens, but not Asca

Reptiliomorpha (meaning reptile-shaped; in PhyloCode known as Pan-Amniota) is a clade containing the amniotes and those tetrapods that share a more recent common ancestor with amniotes than with living amphibians (lissamphibians).

The reptiliomorphs (Reptiliomorpha, “reptilian-shaped”) are a clade of tetrapods that combine both reptile and amphibian characteristics. They originated at the beginning of the Carboniferous period, exhibiting both aquatic and terrestrial forms.

Apr 24, 2019 · Each of the major groups—Amphibia, Reptilia, and Mammalia and their stem-groups—is considered separately. We begin with a general discussion of how teeth work, focusing on their roles in food acquisition and processing.

Dec 5, 2016 · Here we describe five new Tournaisian tetrapods (Perittodus apsconditus, Koilops herma, Ossirarus kierani, Diploradus austiumensis and Aytonerpeton microps) from two localities in their...

The Ichthyosauromorpha are an extinct clade of Mesozoic marine reptiles consisting of the Ichthyosauriformes and the Hupehsuchia.. The node clade Ichthyosauromorpha was first defined by Ryosuke Motani et al. in 2014 as the group consisting of the last common ancestor of Ichthyosaurus communis and Hupehsuchus nanchangensis, and all its descendants.Their …
