Palatinerpeton is an extinct genus of temnospondyl amphibian. Fossils have been found in the Lauterecken-Odernheim Formation of Germany.
Phylogeny.
"Palatinerpeton" is one of several Late Carboniferous and Early Permian European temnospondyls with uncertain affinities; the others include "Iberospondylus", "Sclerocephalus", and "Cheliderpeton". Phylogenetic studies have placed them as either early representatives of a group called Stereospondylomorpha, or close relatives of a group called Eryopidae. Stereospondylomorpha is a large clade mostly made up of Mesozoic taxa, while Eryopidae is a small family consisting of several Carboniferous and Permian temnospondyls. These two groups are usually considered distantly related. Schoch & Witzmann (2009) conducted a phylogenetic analysis in which Eryopidae and Stereospondylomorpha were found to be closely related, both members of a clade called Eryopoidea. "Palatinerpeton" was found to be the sister taxon of Eryopoidea. Below is a cladogram from their study:
