Eucritta
''Eucritta melanolimnetes'' ("the true creature from the black lagoon") is an extinct tetrapod of the extinct genus ''Eucritta'' from the Viséan epoch in the Carboniferous period of Scotland. Its name is a homage to the 1954 sci-fi/horror movie ''Creature from the Black Lagoon''. ''E. melanolimnetes'' was about long, and displayed mixed tetrapod characteristics, such as an amphibian-like skull and a reptilian palate. Its eye sockets were shaped like keyholes, with pointed openings at the front that may have contained a gland of unknown function. This characteristic is also seen in the Loxommatidae family, in which ''Eucritta'' has been placed. However, its exact phylogenetic position is not known with much certainty due to its mixture of primitive and derived tetrapod characters. The possession of characters seen in baphetids, anthracosaurs, and temnospondyls suggests that these three groups diverged in the Carboniferous rather than earlier, in the Devonian.〔Clack, J. A. (1998). ''Nature'' 394: 66-69〕 Five specimens have been found. ''Eucritta'' was described in 1998. ==References==
