Variation present in osteocyte lacunar density (OLD) at different sampling scales. A) intra-skeletal vs. inter-specimen (species mean). B) intra-skeletal variation of CMN 12068 showing mean for each element, as well as lateral and medial values for each sampled element. C) intra-element variation present across a transect of the inner-middle-outer cortex of the fibula of ROM 852, showing the effect of ontogeny on OLD values. Each box represents the standard deviation around the mean (solid black line) of each sampling unit (species, individual, element, or location within element). Each OLD measurement is indicated by a symbol indicating sampling location. Detailed legend shown in figure.
