Westlothiana is a genus of reptile-like amphibians or possibly early reptiles that bore a superficial resemblance to modern-day lizards. It lived about 335 million years ago during the latest part of the Visean age of the Carboniferous period. It is known from a single species, Westlothiana lizziae. The type specimen was discovered in East Kirkton Quarry, West Lothian, Scotland in 1984. Westlothiana's anatomy contained a mixture of both labyrinthodont and reptilian features, and was originally regarded as the first reptile. Most scientists place them among the Reptilomorpha, as a sister group to the first amniotes.

- Westlothiana is an extinct genus of reptile-like tetrapod that bore a superficial resemblance to modern-day lizards. It lived during the Carboniferous period, about 350 million years ago. The type specimen was discovered in East Kirkton Quarry, Bathgate, Scotland, in 1984, and was named after the West Lothian district where it was found. Westlothiana's anatomy contained a mixtures of both early tetrapod and amniote features, and was originally regarded as the first reptile. This species probably lived near a freshwater lake, probably hunting for other small creatures that lived in the same habitat.

Westlothiana's anatomy contained a mixtures of both early tetrapod and amniote features, and was originally regarded as the first reptile. This species probably lived near a freshwater lake, probably hunting for other small creatures that lived in the same habitat. It was later identified as a reptiliomorph, distantly related to the amniotes. Some scientists say that Westlothiana is not even a reptiliomorph, and may have been a far more primitive type of tetrapod. The same as been argued for seymouriamorphs.
