Order: STEGOCEKPHALI. 
This order includes extinct Batrachia that occur in the Coal 
Measures of Ohio, mainly in the Upper Barren Measures which 
are supposedly equivalent to the lower Permian of Western 
Europe.* 
They were often of enormous length, with shapes resembling 
lizards. ‘The head and trunk were heavily armoured by bony 
scales and plates. Twenty-three genera and forty species have 
been thus far described from the rocks in Jefferson and Columbi-
