Solenodonsaurus is an extinct genus of Reptiliomorpha, which lived about 320-305 million years ago. Classification is uncertain, but it was possibly an early reptile or an amphibian close to the diadectomorphs. Its remains were found in the Czech Republic. Its name means, single-tooth lizard.
The Solenodonsaurus show a curious mix of characters making it difficult to place phyllogentically. The teeth lack labyrinthodont folding of the enamle, and it skull is without the otic notch seen in other reptiliomorph amphibians. Yet general build ties it in with the Diadectomorpha.[1]
