lissamphibians造句

• 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 and their extinct relatives ).
• The other two hypotheses are the " lepospondyl hypothesis ", which places all lissamphibians as the closest relatives of a group of lepospondyls called lysorophians, and the " temnospondyl hypothesis ", which has all lissamphibians derived from amphibamid temnospondyls like " Gerobatrachus ".
• The other two hypotheses are the " lepospondyl hypothesis ", which places all lissamphibians as the closest relatives of a group of lepospondyls called lysorophians, and the " temnospondyl hypothesis ", which has all lissamphibians derived from amphibamid temnospondyls like " Gerobatrachus ".
• Phylogenetic studies conducted by Lebedev and Coates ( 1995 ) and Coates ( 1996 ) indicated that " Tulerpeton " was the earliest and basalmost member of the clade containing amniotes and all extinct tetrapods that were more closely related to amniotes than to lissamphibians ( living amphibians ).
• Co-occurring pterosaurs included the small azhdarchid " Eurazhdarcho ", with a wingspan of; The robust, flightless, and possibly herbivorous madtsoiid snake; and the lissamphibians " Albanerpeton ", " Eodiscoglossus ", and " Paradiscoglossus ".
• On the other hand, if lissamphibians are descended from lepospondyls, then not only Lepospondyli would have to be excluded from Reptiliomorpha, but seymouriamorphs, " Gephyrostegus " and Embolomeri would also have to be excluded from this group, as this would make them more distantly related to amniotes than living amphibians are.
• When " Gerobatrachus " was first described in 2008, it was incorporated into a phylogenetic analysis that found it to be the sister taxon or closest relative of Batrachia, an evolutionary group that includes living frogs and salamanders but not caecilians, which are the third major lineage of modern amphibians ( the three main groups of modern amphibians are collectively known as lissamphibians ).
• If it indeed was more closely related to amniotes than lissamphibians are, it would mean that " reduction to five digits had to happen twice, once on the line to amphibians and once on the reptiliomorph line "; on the other hand, if it lies outside the least inclusive clade containing amniotes and lissamphibians, then " digital reduction happened once, between " Tulerpeton " and later tetrapods ".
