Oh, I agree, but I also know that color and texture can be import
*taphonomic* data, and that taphonomic data can help in the analysis
of morphological data (how distorted is the specimen? is this
sculpturing original or an artifact of extraction? and so on).

That was *before* the current rule, and the Code bends over
backwards to avoid ex posto facto rules, so it is not relevent.

However this is. It is clear that I mis-remembered this clause and
incorrectly thought it was a requirement rather than a recommendation.

And then I got it confused with this provision.
The peace of God be with you.
