representing the post-hatching stage) and the fourth, larger stage, likely a subadult. Two different estimates of total length were provided for an incomplete <a href="/wiki/Tibia" title="Tibia">tibia</a> of a subadult specimen collected from an unknown location in the Kirkwood cliffs: either 35 cm (14 in) or at least 42 cm (17 in) long, i.e., four or five times the length of the largest juvenile tibia from the quarry site. Fossil material from the quarry site includes mostly isolated bones (with only five instances of articulation) of hatchling to juvenile individuals of varying size in a 20–30 cm thick horizon, preserved with no apparent preferred orientation of long bones.<sup id="cite_ref-Iyuku_1-3" class="reference"><a href="#cite_note-Iyuku-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>Forster <i>et al.</i> (2022) noted the similarity of this finding to the reported preservation of the juvenile remains of <i><a href="/wiki/Orodromeus" title="Orodromeus">Orodromeus</a></i>, <i><a href="/wiki/Maiasaura" title="Maiasaura">Maiasaura</a></i>, and <i><a href="/wiki/Hypacrosaurus" title="Hypacrosaurus">Hypacrosaurus</a></i>, which might represent aggradations of mortality near nesting sites. Although the remains of <i>Iyuku</i> were not found in association with nests or eggshells, Forster <i>et al.</i> (2022) considered it possible that the concentrations of young individuals of this species represent seasonal attrition at or near a nesting site, with the scattering of bones likely caused by trampling prior to burial or <a href="/wiki/Bioturbation" title="Bioturbation">bioturbation</a> shortly after interment. Bone <a href="/wiki/Histology" title="Histology">histology</a> of multiple young individuals reveals rest lines indicative of temporary arrests in bone deposition, hypothesized by Forster <i>et al.</i> (2022) as caused by repeated, possibly environmentally induced stress during the early stages of ontogeny in these individuals, such as dry and drought-like conditions and/or repeated periods
