Hi Damian! Congratulations on your research, I really liked your talk. I am trying to figure out if I can apply similar strategies for freshwater bivalves, as they have less morphological features to distinguish species than marine species, do you have any suggestions?
About freshwater bivalves with less (or less conspicuous) morphological features I figure at a continous strategy could be the best. This means considering continuous characters such as measurements, proportions and counts. Maximiliano Alvarez employed a similar strategy to deal with venerids (a group that could resemble freshwater bivalves). The baseline is to build a strong database of morphological data. Also, I think that another strategy is to work with geometric morphometric data instead discrete morphological characters: approaches such as disparity analyses or morphospace studies can be easily applied to these data.
Thank you for your answer, your insight is really helpful. And yes, geometric morphometric is already considered as it is the only way to make them comparable, since the preservation does not help to identify features (inner casts mostly in the case of the Jurassic species of Diplodon). Thanks again!
