Taxonomy:

Citation: Lucianorhabdus compactus (Verbeek, 1976) Lees, 2007
Rank: Species
Basionym: Isocrystallithus compactus Verbeek, 1976
Synonyms: Anfractus harrisonii sensu Lambert (1987) - remarkable Albian specimens which were identified as A. harrisonii but appear much closer to L. compactus (and/or O. hillii). The range of varation is greater than has otherwise been illustrated in L. compactus but the large process extensions may not be easily preserved [my interpretation - JRY 2015]
Notes & discussion: Owenia hillii is very similar and was regarded as a junior synonym of L. compactus by Bown et al. (1998) and Bown & Cooper (1998). Lees (2007) however regards them as  separate species.
