Summary
| Description |
Comparisons of the size of the bony core and keratinous sheath of the parascapular spine of Borealopelta to modern bovid and squamate analogues. (A) Absolute size of the bone core (horncore or osteoderm) (yellow) and the overlying keratinous/horn sheath (grey) for the parascapular spine of TMP 2011.033.0001 (top) as well as averages for several bovid and squamate taxa (lower). (B) Schematic representations of the relative bony and keratinous components of select spines/horns (adjusted to same size). Data for Oreamnos americanus (n = 6, 20) and Oreamnos harringtoni (n = 10, 13) from Mead & Lawler (1995), Bos (n = 18) from Grigson (1975), Antilocapra (n = 3) and Bison (n = 18) from Borkovic (2013), Ovis nivicola (n = 2), Ovis dalli (n = 2), Ovis ammon (n = 2), Ovis canadensis nelsoni (n = 5), Ovis canadensis canadensis (n = 8), Capra ibex sibirica (n = 4) and Capra ibex ibex (n = 5) from Bubenik (1990), Trioceros (n = 1) from TMP 1990.007.0350, Phrynosoma solare (n = 1) from LACM 123351, and P. asio (n = 1) from WLH 1093. |
