“…Breakages of vertebral laminae in humans (laminectomy) revealed that trauma arises when fragments displace into the spinal canal 43 . Breakages in Dimetrodon sails revealed a fast-healing system by osteoclastic resorption and deposition of lamellar bone 44 .…”

“…B 281: 20141642 of the sail is usually framed in the context of activity during daylight conditions [42][43][44][45][46][47][48]. Several recent studies have questioned the thermoregulatory role of the sail [49][50][51][52], however, and alternative functions have been proposed that do not require Dimetrodon to have been diurnal (electronic supplementary material).…”

“…Since the early 2000s, FEA has gained traction as a technique for studying the mechanical behavior and performance of extinct and extant organisms, most commonly vertebrates, with particular emphasis on studies of the vertebrate skull (Rayfield et al, 2001;Rayfield, 2007;Strait et al, 2007;Wroe et al, 2007;Wroe, 2008;Dumont et al, 2009Dumont et al, , 2014Tseng, 2009;Tseng and Wang, 2010;Fitton et al, 2012;Porro et al, 2013) or teeth (Spears and Macho, 1998;Macho and Spears, 1999;Anderson et al, 2011;Anderson and Rayfield, 2012;see D. Jones et al [2012a]; D. Jones et al [2012b]; Murdock et al [2014]; and Mart ınez-P erez et al [2014] for examples using FEA on conodont elements). Recently, FEA of the postcranial skeleton has been gaining attention (e.g., Schwarz-Wings et al, 2009;Piras et al, 2012;Rega et al, 2012;Brassey et al, 2013;O'Higgins and Milne, 2013). Typically these analyses assume a linear elastic behavior for bone and model loading under static rather than dynamic conditions (but see Wang et al, 2012).…”
