“…Osteoderms are widespread integumentary features that occur in diverse extinct and extant amniotes, including turtles, nonavian archosaurs, lepidosaurs, and cingulatan mammals (Burns et al, 2013 ; Hill, 2005 ; Moss, 1972 ; Romer, 1956 ; Vickaryous & Sire, 2009 ; Witzmann, 2009 ). Osteoderms can bear superficial ornamentation in the dorsal surface, which may show different morphological patterns, such as tubercles in lizards, turtles, temnospondyls, and armadillos (de Buffrénil et al, 2011 ; Scheyer et al, 2007 ; Sena et al, 2021 ; Vickaryous & Hall, 2006 ; Witzmann & Soler‐Gijón, 2010 ), and pits and grooves in crocodylomorphs (Marinho et al, 2006 ; Montefeltro, 2019 ). The osteohistology of osteoderms is heterogeneous (Vickaryous & Sire, 2009 ) comprising blood vessels, nerves, yellow marrow, a collagenous meshwork, and cancellous and cortical bone (Kirby et al, 2020 ; Moss, 1972 ; Vickaryous & Sire, 2009 ).…”
