[edit] May not be possible
A Screenshot may not be possible. The show is under copy right, and it would be illegal obtain a screenshot, much less post it here. —Preceding unsigned comment added by 64.10.60.147 (talk • contribs) 16:46, 5 August 2006 64.10.60.147
[edit] Reptile, Amphibian, Other?
"Seymouria was a reptile-like tetrapod ... with many reptilian features ... it was first thought to be a primitive reptile. ... in the television series Walking with Monsters ... It was erroneously called an amphibian."
Hmm, clicking on Reptiliomorpha in the taxobox ... "Reptiliomorpha is a name given ... to reptile-like tetrapods ... Michael Benton (2000, 2004) mades it the sister-clade to Batrachomorpha. ... Reptiliomorpha is given the rank of superorder and only includes reptile-like amphibians [Systema Naturae 2000]. More recently Reptiliomorpha has been adopted as the term for the largest clade that includes - according to the technical definitions of the phylocode which only refers to species or genus level organisms - Homo sapiens but not Ascaphus truei (a primitive frog)"
So: Reptiliomorphs are amphibians? Reptiles? Or is this obsolete Linneaean thinking?
Could somebody please add a few words to Seymouria to clarify this? Thanks. -- Writtenonsand 18:36, 11 April 2007 (UTC)
- Amphibian is being used two different ways, which is causing the confusion. Traditionally, Class Amphibia included the entire paraphyletic grade from Ichthyostega to reptiles. Most modern scientists only use the name Amphibia to refer to the group contaning the modern forms, i.e. frogs, salamanders, etc, which also might include temnospondyls like Eryops, etc. This leaves all the other traditional amphibians outside a class, but a lot of people still refer to them as "amphibians" informally. I'd change the phrasing on Reptiliomorpha to "Includes reptile-like tetrapods" to clear this up. Dinoguy2 01:49, 12 April 2007 (UTC)
