A simple method for differentiating two similar accelerator-based black hole creation mechanisms -- compactified extra dimensions and unparticle-enhanced gravity -- is discussed, in light of several properties of black hole thermodynamics. The real-valued scaling dimension $\du$ will induce interactions that mimic those in a universe with $(2\du-2)$-extra spatial dimensions, and thus provides an alternative mechanism for black hole creation at the LHC within the confines of standard 4D general relativity. This results in mass-dependent Hawking temperature profiles that depend primarily on $\du$, yielding an evaporation signature unique to the framework. Specifically, a precision reconstruction of the Hawking temperature spectrum morphology for black holes of mass $\Mbh$ yields conclusive evidence of one mechanism over the other, due to the presence of additional adjustable parameters in the unparticle sector.
