The study constructs a 3D whole-body biomechanical model of the Late Triassic archosaurian reptile Lagosuchus talampayensis, which includes reconstructions of the hindlimb musculature. The process of constructing the model revealed that numerous limb bones curated with the main specimens are from other, as-yet-undetermined archosaurs. The model's muscle sizes and strengths are estimated via two techniques and compared, showing broadly similar results. The data obtained are placed into a phylogenetic context, revealing preliminary estimates of how skeletal changes relatec to changes of muscle sizes across Archosauria.

The bat orofacial complex may enhance our understanding of bat evolutionary diversification and offer insights into the developmental mechanisms of human cleft palate.

The superior gluteal nerve (SGN) is a mixed nerve of the sacral plexus that arises from the posterior divisions of the L4, L5, and S1 nerve roots. The aim of this meta-analysis was to obtain all relevant data on SGN and its variations. In this study, the authors found that the closest SGN branch to GT was a muscular branch for gluteus minimus muscle, situated less than 4 cm from GT (95% CI: 27.8–49.3). As for the pattern presented by SGN, we found the higher prevalence of the spray pattern in the general population, 70.4% (95% CI: 54.4–96.8), which presents with clinically significant complications, as for predicting the nerves' pathway and may slightly increase surgical difficulty.
