Dear Daniel,
to my knowledge, describing the landmarks that do not correspond to
well known anatomical structures is common place so I guess there
shouldbe no problem with this. I imagine that making up new names
should be evaluated on a case by case basis but it's not very common
(most studies are concerned with covering adequately the shape of a
structure to answer questions about the underlying biology, not to
names of landmarks per se).
Reading the descriptions of the points you provided, it sounds like
many of them are not type I landmarks (sensu Bookstein 1991 -
Morphometric Tools for Landmark Data) and, at least in some cases,
maybe would be best treated as semilandmarks.
I hope this helps...
Best,
Carmelo
