“…Therefore, hind limb and foot bones of a single individual would yield different assessments of relative maturity if analysed in isolation. For example, the inference that an Alaskan ornithomimosaur [ 26 ] was approaching somatic maturity at the time of death based on a decreasing pattern of LAG spacing in a single, isolated metatarsal, is poorly substantiated.…”

“…Horner et al [ 16 ], or the outer circumferential layer, or OCL, following Cormack [ 17 ]) has been used to infer somatic maturity in sampled individuals [ 7 , 14 , 15 ]. In the absence of an EFS, patterns in the relative spacing of LAGs has been used to infer the ontogenetic stage of an individual, in some cases using a single sectioned element [ 2 , 8 , 18 - 26 ]. On a finer scale, the density of osteocyte lacunae (osteocyte lacunar density, OLD) in the cortex of limb bones of tetrapods has been suggested to be related to mechanical forces and differential loadings, basal metabolic and growth rates, and element structural differences [ 27 - 29 ], and osteocyte lacuna morphology itself has also been shown to be related to these properties [ 27 , 29 , 30 ].…”

“…Spacing between lines of arrested growth is often used to qualitatively assess the relative growth rates and maturity in isolated bones, e.g. Tyrannosaurus [5,7], Alioramus [18], Raptorex [23,25,26], and a putative Alaskan ornithomimosaur [26]. This method assumes that a decrease in LAG spacing from the inner cortex to the periosteum corresponds with an individual approaching somatic maturity.…”

In the absence of an EFS, patterns in the relative spacing of LAGs has been used to infer the ontogenetic stage of an individual, in some cases using a single sectioned element [2,8,[18][19][20][21][22][23][24][25][26].

“…Ornithomimosaurs spanned three orders of magnitude in body size [ 29 ], from an estimated 5.3 kg ( Nqwebasaurus [ 30 ]) to 620 kg ( Beishanlong [ 26 ]) and exceptionally in excess of 6000 kg ( Deinocheirus [ 31 ]). Phylogenetic ghost lineages imply that ornithomimosaurs had originated by the Middle Jurassic, and attained a broad distribution during the Cretaceous [ 32 ], including paleo-arctic [ 33 ] and Gondwanan [ 30 ] occurrences. In this study, we provide a comprehensive description of the vertebral pneumaticity of Archaeornithomimus and survey the degree of pneumaticity in other ornithomimosaurs to determine the macroevolutionary pattern of vertebral pneumaticity in Ornithomimosauria.…”
