Like other similar fish, it had thick layers of bony scales, which probably helped protect it from predation by other fish and nothosaurs. TaxonomyThere is one known species, Pristiosomus merlei. It has been classified in both the Semionotiformes and the Pholidopleuroformes at different times. It was placed in the Pholidopleuroformes due to its similarity to Australosomus merlei (Piveteau).[3] EtymologyPristiosomus comes from the Latin 'pristis' meaning 'sea monster' or 'shark' and the Greek 'soma' meaning 'body'. merlei refers to a person after whom it was named.
