本研究通过三维几何形态测量学 (3D geometric morphometrics)和线性异速生长分析，揭示了山羊颅骨在胚胎期与出生后的显著发育差异。研究人员发现：山羊作为早熟型哺乳动物 (precocial mammals)，其颅骨生长在胚胎阶段呈现更高的生长速率，尤其表现在内脏颅 (splanchnocranium)和脑颅 (neurocranium)相关变量；角 ...

The postnatal growth of the viscerocranium in relation to the neurocranium of Pan troglodytes verus has been investigated using standardized lateral cephalograms. Sex and age were determined on the ...

A new taxon of the Prophaethontidae (Aves) is described from the phosphatic beds of the Ouled Abdoun Basin, Morocco. Lithoptila abdounensis gen. et sp. nov. is represented by a single, well-preserved ...

To reach this conclusion, the team conducted CT scans of the child’s neurocranium —the part of the skull that protects the brain—and jaw. They compared the resulting 3D models to remains of ...
