Attenosaurus subulensis is a fossil salamander of the order Anthracosauria ("coal lizards") which flourished during the Carboniferous period and early Permian periods of the Paleozoic era (between 290 and 350 million years ago).
Attenosaurus subulensis was approximately the size of a large dog and was the largest terrestrial animal alive before the emergence of dinosaurs in the Mesozoic era.
Numerous fossil tracks of Attenosaurus subulensis have been found at the Steven C. Minkin Paleozoic Footprint Site, the former Union Chapel Mine near Sumiton in Walker County. At the time the area was part of an alluvial plain with tropical forests and tidal flats bordering the shore of an ocean which covered two thirds of the state.
