2 thoughts on “Unicuspid and bicuspid tooth crown formation in squamates”

   The paper I’ve been waiting for Handrigan & Richman to produce, perfect!

   The one line summary/key finding, for those who are interested:

   “Cusp formation in the (multicuspid) gecko does not occur by the folding of the inner enamel epithelium, as in the mouse molar, but by the differential secretion of enamel.”

   The gecko teeth are kind of only just multicuspid, however, so I wonder if this only applies to ‘kind of only just multicuspid’ taxa rather than fully multicuspid teeth.

   Thanks Jackie.

   Hmm

   Axolotls are supposed to have bicuspic pedicillate teeth, why not check those?

   Oh, sorry, somebody already did…
