Hemilampronites is a prehistoric genus of marine ray-finned fish from the Late Cretaceous. It contains two species, both known from isolated scales: H. steinlai Geinitz, 1868 known from the Turonian of Germany & H. hesperius Cockerell, 1917, known from the Maastrichtian-aged Fox Hills Formation of Colorado, US.[1] Unverifiable records of H. hesperius have also been noted from the Maastrichtian-aged Quiriquina Formation of Chile.[2]

The scales closely resemble those of the modern halfbeak Hyporhamphus, and also resemble those of the Scomberesocidae and Exocoetidae. A close relationship to the modern Beloniformes has thus been suggested; however, as the Beloniformes have a sparse fossil record & no Cretaceous body fossils of them are known, and the only fossils of Hemilampronites are isolated scales, the proper classification of this genus remains uncertain.[1][3]
