Sharks have dermal denticles that share developmental origins. Currently we don't include location information due to this diversity, but in future we may include specific subclasses and/or taxon GCIs. dental primordium An tooth placode is a thickening of the ectoderm that will give rise to the tooth bud[GO]. tooth primordium tooth anlage Placode that develops into a tooth. The placode is a thickening of the pharyngeal epithelium.[TAO] BTO:0001511 ZFA:0001153 dental anlage TAO:0001153 presumptive structure non-neurogenic ectodermal placode
