Eucritta melanolimnetesJennifer A. Clack
Eucritta melanolimnetes is a recently described species of tetrapod from the Visean of Scotland. It is one of a range of tetrapods found at the East Kirkton Quarry near Edinburgh. Other taxa include anthracosaurs, temnospondyls, stem amniotes and aistopods, and they represent the earliest known terrestrial tetrapod fauna. Eucritta shows a mixture of temnospondyl-like (eg. wide otic notch) and anthracosaur-like (eg. closed palate, girdle features) characters, but also shows incipiently the anterior embayment of the orbit found in baphetids. It clusters with baphetids in phylogenetic analyses (eg. Clack 1998, 2001, Ruta et al. 2003), as the basalmost member of the clade.
