A nice slipper shell. Not a common find, especially in good shape.
Forum Member MikeR has made the following notes on this sub-species in his gallery." Cambell, in his 1994 paper listed all spiny slipper shells as one of two sub species of B. aculeata. The subspecies ponderosa is inflated and can be variable in the amount of spines as stacked individuals will remove the spines of the one below them. Being the lifestyle is different from the extant B. aculeata, sub species ponderosa could be a different species."
I agree with Mike's assessment of this, this should possibly be considered it's own species.
