Cochleosaurus and Chenoprosopus

Cochleosaurus bohemicus (Fritsch 1885; C. forensis Rieppel 1980; Moscovian, Late Carboniferous; 310 mya; 1.2-1.6m) was named for the spoon-like processes at the back of the skull. Traditionally and here it nests as temnospondyl close to Nigerpeton. The open palate is similar to that found in lepospondyls. Note the septomaxilla. The blue bone is the lacrimal.

Chenoprosopus mileri (Mehl 1913; Late Carboniferous; 10–30 cm skull length; New Mexico) is a sister to Cochleosaurus with 3D preservation. No lateral lines cross the skull. This was likely a terrestrial carnivore.
