The mineralization of the skeleton from hatching to near maximum size in two phrynosomatid lizards, Callisaurus draconoides and Uta stansburiana, is described in detail. Observed patterns in the appearance of epiphyseal secondary centers, ossification centers, apophyseal ossifications, and calcifications, the distribution of sesamoids, and the timing of fusions, are compared and contrasted with observations of other squamates available in the literature. Overall, Callisaurus and Uta exhibit an advanced state of ossification in the hatchling relative to other squamate neonates and share a similar sequence of braincase fusions and appearance of secondary centers. Preliminary observations suggest that patterns of postnatal skeletal development are highly conserved and independent of patterns of prenatal morphogenesis, and thus a potentially rich source of character data for systematic investigations.
详细描述了两种角蜥科蜥蜴（斑纹强棱蜥和史氏强棱蜥）从孵化到接近最大体型时骨骼的矿化过程。将观察到的骨骺次级中心、骨化中心、突骨化和钙化的出现模式、籽骨的分布以及融合时间，与文献中其他有鳞目动物的观察结果进行了比较和对比。总体而言，相对于其他有鳞目新生幼体，斑纹强棱蜥和史氏强棱蜥在孵化幼体时表现出较高的骨化状态，并且在脑壳融合顺序和次级中心出现方面具有相似性。初步观察表明，出生后骨骼发育模式高度保守，且独立于产前形态发生模式，因此是系统研究中潜在的丰富特征数据来源。
