“…Although difficult to document experimentally (e.g., LANYON, 1974), several models of trabecular bone development and remodeling support this trajectorial interpretation (KOCH, 1917;RYBICKI et al, 1972;FYHRIE and CARTER, 1986). With this in mind, the orientation of the primary trabecular concentration of the proximal femur, the compression or "medial" trabeculae , was investigated in modem and late archaic humans (HELLER, 1989).…”

The interpretation of the evolution of human manipulative and locomotor behavior from hominid fossil remains during the Pleistocene requires a clear distinction between changes in relative musculo-skeletal massiveness indicating different levels of activity (robusticity) and alterations in form implying contrasting patterns or frequencies of behavior. A review of ongoing research on Neandertal appendicular morphology with respect to the scapulo-humeral articulation, the pollical and mid-carpal carpo-metacarpal articulations, proximal femoral trabecular orientation, femoral diaphyseal cross-sectional geometry, and proximal pedal phalangeal diaphyseal proportions illustrate the nature of the problems associated with making distinctions between robusticity and shape in fossil hominid remains. Nonetheless, it is apparent that differences in shape, in addition to contrasts in robusticity, exist between the Neandertals and modern humans.

“…The technique was conceived in the late 1940s and 1950s (Turner et al, 1956) and by the 1970s became widely used in the fields of engineering and orthopedic science (Zienkiewicz, 1971;Brekelmans et al, 1972;Rybicki, 1972). FEA, now generally an automated computerized technique, divides the structure of interest into a finite number of subregions known as elements, each possessing user-specified material properties.…”

Using finite‐element analysis to investigate suture morphology: A case study using large carnivorous dinosaurs

Finite-element analysis (FEA) can be used to investigate the mechanical significance of sutures and regions of intracranial flexibility in skulls. By modeling the stress response to feeding forces in a finite-element skull model (with appropriate boundary conditions), one can compare the axis of distortion and orientation of stress and strain in the model to the degree of movement at actual sutural contacts in the real skull. Hypotheses detailing the effect of introducing patency or flexibility on mechanical performance can be constructed and subsequently tested. In this study, the correlation between stress environment, cranial strength, and sutural morphology and mobility is investigated in the cranium of the large theropod dinosaur Allosaurus fragilis. Theropods are an especially interesting model system as their skulls were massive (over 100 cm in some cases), may have generated extremely large bite forces, yet patent sutures persisted between many of the facial bones. In this analysis, it was discovered that Allosaurus cranial sutures appear generally capable of accommodating stress and strain patterns generated during biting. This study highlights the potential of FEA in devising and testing hypotheses of form and function and argues that useful information can be obtained from finite-element models of extinct animals, providing that adequate assumptions are made and appropriate questions asked.
