[1] It is known from only 2 partial skulls and several dorsal vertebrae discovered in the Bahariya Formation that was destroyed during World War II.

[3] The first and only remains of Paranogmius were discovered by crews working for Ernst Stromer in 1916 in the Gebel el Dist district of the Bahariya Oasis in Egypt, and were taken to the Palaeontological Museum, Munich.

[2] Weiler noted the great size of the remains, with one of the partial skulls, the type (BSPG 1912 VIII 99), preserved at 45 centimeters long.

[4][5] Paranogmius was a Plethodid, meaning it likely had a large dorsal fin and a fusiform body like its relatives.

Paranogmius also shares the triangular head shape, chewing plate, and wide snout with Plethodids like Pentanogmius.
