Temporal range: Early Carboniferous Brigantian
|Life restoration of Silvanerpeton miripedes|
Silvanerpeton is an extinct genus of early reptiliomorph found in East Kirkton Quarry of West Lothian, Scotland, in a sequence from the Brigantian substage of the Viséan (Lower Carboniferous). The find is important, as the quarry represents terrestrial deposits from Romer's gap, a period poor in fossils where the higher groups labyrinthodonts evolved. Based on a remarkably well preserved humerus and other traits, the animal is believed to have been an advanced reptile-like amphibian, close to the origin of amniotes.
In life Silvanerpeton was about 40 cm (1 ft) long. Some paleontologists think it was semi-aquatic as an adult, others believe only young Silvanerpeton were aquatic and the adults were fully terrestrial.
