Large tristichopteridae (Sarcopterygii, Tetrapodomorpha) from the late Famennian evieux formation of Belgium

Abstract

Remains of two large sarcopterygians are described from Famennian deposits in Belgium. One of them is referred to Eusthenodon wängsjöi Jarvik; it is the first occurrence of this genus in Belgium. The other, much larger one, appears to be a tristichopterid. It has a postspiracular; size and shape of the mandible similar to those of Platycephalichthys skuenicus and P. bischoffi; snout and cheek patterns close to those of Eusthenodon; unusual shape of the supratemporal resembling that of Hyneria, Mandageria and Platycephalichthys skuenicus; and tooth histology quite similar to that of Eusthenodon and Platycephalichthys.
