The Furcula as a High-Speed Thermal-Mechanical Bridge: Evidence of a Warm-Core Sensory Hub and Regional Heterothermy in Theropod Phyla Dating to the Late Triassic (~210 Ma)

The evolutionary success of the Theropoda has long been attributed to locomotor and metabolic innovations, yet the specific sensory requirements of high-speed coordination in fluctuating environments remain under-examined. This paper proposes that the dinosaurian furcula serves as a High-Speed Bone-Conduction Mechanosensory Organ (HSBCMO), acting as a "Thermal-Mechanical Bridge" between the extremities and the central nervous system. By integrating the Avian Flight Neural Conduction Index (AFNCI), we demonstrate that peripheral nerves in the limbs of heterothermic dinosaurs would have suffered from significant "Thermal Latency Failure" during environmental cooling [1]. The existence of a fused furcula in the Late Triassic (~210 Ma) provides physical evidence of a "Warm-Core" sensory hub required to satisfy the "Thermodynamic Imperative" [3]. Furthermore, we propose the "Principle of Physiological Precedence," inferring that a warm-core metabolic chassis must have preceded the anatomical arrival of the furcula by approximately 30 million years, placing the origin of the dinosaurian "Warm-Core" in the Middle Triassic (~240 Ma).
