Specimens included in the current study. FMNH 223983 (denoted with an asterisk), has one additional transitional lumbar-sacral vertebra, which is fused to the first sacral and was therefore not included. Holotype of Scutisorex thori denoted with a double asterisk. Total = total presacral number, including third cervical (C03) through last lumbar. Diaph = diaphragmatic position, For example, 20 (T15) means that the diaphragmatic vertebra is position 20 in the overall presacral column, corresponding to the fifteenth thoracic position.
