Second Phalanx
For the purpose of analysis, lateral left and medial right elements are defined as left. Medial left and lateral right elements are defined as right.
Elements where the proximal and/or distal epiphyses are un-fused and not with the specimen are coded as though the epiphyses are missing.
Elements where the proximal or distal epiphyses are un-fused but are present during coding, the un-fused epiphyses are grouped together for coding and cataloguing and are not counted as separated pieces.
For an un-fused epiphysis unassociated with the rest of the element it is assigned an appropriate BU number.
For the Fincastle Project, Bone Units 13, 14, 15 and 16 were added.
BU 1
SC A
Complete element.
BU 9
SC B
Element with small portion of proximal end absent. Approximately ¾ of element remaining. (DS)
BU 2
SC C
Consists of complete proximal ½ - 2/3 of element. Defined as 84.12.05 for moose element from Crown site.
BU 8
SC D
Lateral ½ of element. Opposite of BU 7. (DS)
BU 7
SC E
Medial ½ of element. Opposite of BU 8. (EMA)
BU 10
SC F
Posterior half of entire element split along its transverse plane. (WU)
BU 6
SC G
Proximal unfused epiphyses detached and not associated with rest of element. Code condition as "weathered".
BU 4
SC H
Consists of major portion but not complete proximal end with no or minor portion of adjoining shaft. Defined as 84.12.12 for ungulate specimen from Crown site.
BU 11
SC I
Lateral half of proximal end of element. Most of the element distal to the articular facets is missing. (WU)
BU 5
SC J
Distal ½ - 2/3 of element.
BU 3
SC K
Consists of major portion but not all of distal articular surface with none or only minor portion of adjoining shaft. Defined as 84.12.05 for moose element from Crown site. Frequency indicates minimum number of elements.
BU 12
SC L
Anterior portion of the distal articular condyle, side indeterminate. (WU)
BU 13
SC M
Complete distal portion only missing the un-fused epiphysis. Opposite of BU 6. (SB)
BU 14
SC N
This is the internal bone structure only, the outer bone layer, the periosteum, is removed. (SB)
BU 15
SC O
Medial or lateral portion of proximal epiphysis (juvenile). (SB)
BU 16
SC P
Fragment of bone. Identifiable by shape and curvature. (SB)
