Recently, realizing new fermions, such as type-I and type-II Dirac/Weylfermions in condensed matter systems, has attracted considerable attention.Here we show that the transition state from type-I to type-II Dirac fermionscan be viewed as a type-III Dirac fermion, which exhibits uniquecharacteristics, including a Dirac-line Fermi surface with nontrivialtopological invariant and critical chiral anomaly effect, distinct frompreviously known Dirac semimetals. Most importantly, we discoverZn$_2$In$_2$S$_5$ is a type-III Dirac semimetal material, characterized with apair of Dirac points in the bulk and Fermi arcs on the surface. We furtherpropose a solid-state realization of the black-hole-horizon analogue ininhomogeneous Zn$_2$In$_2$S$_5$ to simulate black hole evaporation with highHawking temperature. We envision that our findings will stimulate researchersto study novel physics of type-III Dirac fermions, as well as astronomicalproblems in a condensed matter analogue.
