    Summary
    This summary is machine-generated.

    Skeletal proportions in Hyaenidae, Canidae, and Felidae reveal adaptations for prey capture and stability. Proteles cristatus exhibits unique limb proportions, blending Hyaenidae traits with Canidae-like hindlimbs.

    Area of Science:

    • Comparative anatomy
    • Paleontology
    • Biomechanics

    Background:

    • Body proportions influence locomotion and feeding strategies in carnivorans.
    • Hyaenidae, Canidae, and Felidae exhibit diverse ecological niches and predatory behaviors.

    Purpose of the Study:

    • To compare skeletal measurements and body proportions across Hyaenidae, Canidae, and Felidae.
    • To investigate the functional morphology and evolutionary implications of limb segment lengths in these families.

    Main Methods:

    • Analysis of skeletal measurements and limb segment indexes.
    • Comparative morphometrics of fossil and extant species within Hyaenidae, Canidae, and Felidae.

    Main Results:

    • Hyaena and Crocuta show long necks/forelimbs, short humeri, long radii/metacarpals, long femora, and short tibiae, adapted for heavy prey and stability.

  • Proteles cristatus shares long neck/forelimb traits with other Hyaenidae but possesses longer hindlimbs with more canid-like proportions.

    • Conclusions:

    • Limb proportions in Hyaenidae are strongly correlated with prey size and hunting strategies.
    • Proteles cristatus displays a unique mosaic of skeletal adaptations reflecting its specialized insectivorous diet.
