Without full illustration of simpson’s types it is almost impossible to obtain due knowledge of lias ammonites, and certainly dangerous to describe or name species as new” (buckman, yorkshire type ammonites, 1909, quoted by sheppard in “martin simpson and his geological memoirs”, proceedings of the yorkshire geological society, 1918).
The type specimens of 38 species are figured, many of them for the first time.

Howarth described a similar type of ammonite as dactylioceras (orthodactylites) semiannulatum in his 1978 paper “the stratigraphy and ammonite fauna of the upper lias of northamptonshire”. It is a late survivor of the orthodactylites subgenus, in later beds replaced by ammonites with mostly bifurcating ribs of the dactylioceras genus.
Most shell preserved ammonites in yorkshire come from more or less hard nodules that formed around the decaying animal. With some of the nodules, especially from some beds in the upper sinemurian, it is the hardness difference between shell and nodule that can be used to extract an ammonite with shell more or less intact.
In howarth 2002 the ammonite was pictured and full details were given for the original describer and the year, a list of synonyms (asteroceras marstonense spath is one), some museum references, and, in the references the name of the publication where spath described the ammonite “notes on yorkshire ammonites.
