Hyoid

Only the two great cornua are considered here as the hyoid for bone unit analysis. All other hyoid pieces that are not part of the great cornua are coded as “undifferentiated scrap.”
For the Fincastle Project, Bone Unit 14 was added.

BU 1
SC A
Complete element.

BU 7
SC B
Element complete except for removal of 1/3 or less of anterior end of shaft.

BU 10
SC C
Element complete except for removal of greater than 1/3 – 2/3 of anterior end of shaft.

BU 6
SC D
Consists of posterior ½ - 2/3 of shaft and all of or most of dorsal cartilaginous surface. Muscular angle removed. Similar to BU 12.

BU 12
SC E
Unit consists of dorsal extremity and 0 – ½ of shaft. Muscular angle removed. Similar to BU 6. (KK)

BU 3
SC F
Fragment of dorsal extremity consisting primarily of dorsal cartilaginous surface and immediately adjacent portion.

BU 5
SC G
Consists of posterior ½ - 2/3 of shaft and all of muscular angle. Dorsal cartilaginous surface has been removed. Similar to BU 9.

BU 9
SC H
Unit consist of 0 – ½ of shaft and all muscular angle. Dorsal cartilaginous surface has been removed. Similar to BU 5.

BU 13
SC I
Consists of most or all of muscular angle detached from rest of element. (MB)

BU 11
SC J
Same as BU 4, but with from posterior ¼ to all of shaft present.

BU 4
SC K
Medial portion of dorsal extremity formed by removal of shaft, muscular angle of dorsal extremity and dorsal cartilaginous surface. Similar to BU 11.

BU 2
SC L
Complete or essentially complete shaft of great cornu. Dorsal extremity and muscular angle completely missing.

BU 8
SC M
Small fragment of shaft. Note: Frequency indicates number of pieces only.

BU 14
SC N
Similar BU 4. Medial portion of dorsal extremity. Shaft removed, muscular angle of dorsal extremity removed. 90% of dorsal cartilaginous surface present (‘cap’ missing only). (SB)
