Abstract: Metabolic heat production in archosaurs has played an important role in their evolutionary radiation during the Mesozoic, and their ancestral metabolic condition has long been a matter of debate in systematics and palaeontology. The study of fossil bone histology provides crucial information on bone growth rate, which has been used to indirectly investigate the evolution of thermometabolism in archosaurs. However, no quantitative estimation of metabolic rate has ever been performed on fossils using bone histol… Show more

“…Vascular density is low or tissue may be even avascular. FLB consists largely of woven and centripetally deposited lamellar bone (primary osteons), and the matrix shows a high vascular density (Francillon-Vieillot et al, 1990;Cubo et al, 2005;Legendre et al, 2016). Like LZB, FLB can be stratified by growth marks, as was described for some dinosaurs (Horner et al, 2000;Horner and Padian, 2004;Klein and Sander, 2007) and mammals (e.g., Sander and Andr assy, 2006;K€ ohler et al, 2012).…”

“…Arguments based on the characteristics of the cardiovascular architecture as early as in the egg likely precede other theories about the evolutionary onset of endothermy, such as change in juvenile and adult growth parameters, adult metabolic rate, or oxygen handling and mitochondrial activity . A further argument from embryo‐related studies came from analysis of fossil egg shells.…”
