Tom asked about the possible whereabouts of an illustration of a
raccoon baculum. If you can get hold of it, the following is a
good source: William H. Burt. 1960. Bacula of North American
Mammals. Univ. Michigan Museum of Zoology, Miscellaneous
Pubications, 113:1-76.
As for articulation, none in any real sense--basically a stiffening
structure.
