Solenodonsaurus
is named after having teeth that are the same type, sharp and slightly
curved, suitable for catching insects. The ear structure is simple and
probably could only pick up lower pitch sounds. While it has been
placed in Reptilomorpha under labyrinthodonts, it does not have the
characteristic labyrinthodont teeth. The spine however is more
characteristic of terrestrial amphibians.
Its
precise classification
has been difficult to clearly establish and may possibly change in the
future, especially with the advent of new discoveries. One thing that
can be said is that it is either an example of an early amniote or a
group that is closely related to them.
