We have studied electron-induced ion-pair dissociation dynamics of CO usingthe state-of-art velocity map imaging technique in combination with atime-of-flight-based two-field mass spectrometer. Extracting thecharacteristics for O$^-$/CO nascent atomic anionic fragments from the lowenergy (25 - 45 eV) electron-molecule scattering, first-time, we have directlydetected the existence of S-wave resonated Trilobite resembling a novelmolecular binding energy mechanism, as predicted by Greene \textit{et al.}\cite{greene2000creation}. The energy balance demands ion-pair dissociation(IPD) lie within a long-range (<1000 Bohr radius) heavy Rydberg system.Modified Van Brunt expression capturing the deflection of dipole-Bornapproximation is used to model the angular distributions (AD) for the anionicatomic fragments. The AD fits reveal that the final states are dominantlyassociated with $\Sigma$ symmetries and a minor contribution from $\Pi$symmetric states that maps the three-dimensional unnatural oscillation ofBorn-Oppenheimer's potential.
