Phylogenetic relationships of the triassic archaeosemionotus deecke (halecomorphi, ionoscopiformes) from the 'perledo fauna'.

The lagerstätten in the Monte San Giorgio have provided excellent fossils representing one of the most important windows to the marine life during the Triassic. Among these fossils, fishes are abundant and extraordinarily well preserved. Most of these fishes represent extinct lineages and were diffi...
