Order Piciformes Family Picidae


REFERRED MATERIAL Distal mandibular symphysis, DMNH 30080.

provenance Location 1349, Velvet Room, Mark's Sink.

DESCRIPTION This specimen is referred to Picoides, and not Colaptes, by its relatively longer symphysis (short in Co-laptes). In addition, Melanerpes has a shallower symphysis than Picoides; in Sphyrapicus, the proximal opening to a middle canal in the symphysis is more open and excavated than in Picoides. The fossil is recognized as P. villosus by its similarity in symphyseal length and breadth (much broader in P. tridacty-lus, broader and longer in P. arcticus, smaller in P. pubescens).
