Short summary
This work is based on scales of a new group of Cretaceous South American fishes. Detail studies about scales are very useful, considering that many fossil fishes are known because of their squamation. Comparisons with other Mesozoic fishes were made. Among main conclusions are that these fishes present lepisosteoid-type scales (with enamel but without dentine) and in particular paired dorsal scales in the position where other fishes commonly have median dorsal ridge scales.
