In most respects,Dipterus,which was about 35 centimetres (14 in) long, closely resembled modern lungfish. Like its ancestorDipnorhynchus,it hadtooth-like plates on itspalateinstead of real teeth. However, unlike its modern relatives, in which thedorsal,caudal,andanal finare fused into one,Dipterus's fins were still separated.[3]
The genus was established byAdam Sedgwick&Roderick Murchisonin the year 1828.
