Rhamphorhynchus gemmingi (von Meyer 1846) TM 6922/6923, no. 74 in the Wellnhofer catalog, Late Jurassic, ~155 mya, was a sister to R. muensteri and phylogenetically preceded other specimens within this species, such as no. 43.
Distinct from R. muensteri the skull of R. gemmingi had a more sharply pointed snout and the naris was largely dorsal to the antorbital fenestra, which was larger. The mandible was not so sharply upcurved. The holotype skull is 1.5 times longer than in the Tischlinger specimen but the torso is only 1.25 times longer.
The cervicals were longer relative to the dorsals. The tail was more robust.
The sternal complex was narrower. Other than the smaller humerus, the forelimbs were not preserved.
The ilium posterior process was longer. The pubis was shorter than the ischium.
