Rodzaj Baltoniodus Linsatrom, 1971

Gatunek typowy
Prioniodus navis Lindström, 1955.

Opis

Probably both S1 and S2 elements tetraramous (unlike the Lenodus lineage with only one such elements pair). The P1 elements with a weakly denticulated or adenticulated anterior process, M elements with weakly denticulated external process. 

Generally the Baltoniodus species were cold-water faunal elements. Late species of Baltoniodus developed a lobate platform, but their anterior process is not ramified.
