Taxonomy from Fossilworks.org. Prepped by transfer method (Toombs, Harry; A.E. Rixon (1950). "The use of plastics in the "transfer method" of preparing fossils". The museums journal. 50: 105–107.) As far as I know, four bat genera with a total of 8 species are known from Messel: Palaeochiropteryx tupaiodon and P. spiegeli, Archaeonycteris trigonodon and A. pollex, Trachypteron franzeni, Hassianycteris messelense, H. magna and Hassianycteris? revilliodi. The genus Palaeochiropteryx is the most common and smallest bat from Messel with a wingspan of around 26 to 29cm. Archaeonycteris is rarer and somewhat larger - the wingspan is about 37cm. The largest bat in Messel is Hassianycteris magna with a wingspan of almost 50cm. Bat with partially preserved flight skin and ears. What is peculiar about this piece is that the bones show fractures. The forearm bones (ulna and radius) on both sides are broken in exactly the same place. Additionally, one of the lower legs may have been broken as well. Diagnosis from Russel & Sigé p. 124 (translated from French by oilshale): "larger size than Palaeochiropteryx tupaiodon. P3 relatively wider and shorter; protoconid lower; tubercles of lower molars less high and less acute; trigonid of M1 forming a more equilateral triangle; talonid of M3 notably narrow, and lower relative to trigonid. Upper canine relatively shorter and broader at its base than that of P. tupaiodon; its horizontal outline less acute posteriorly; talon of P³ broader lingually, with its posterior margin more transverse to the dental series; on M1-M², notch between mesostyle and parastyle less deep." Identified by Dr. G. Storch, Forschungsinstitut Senckenberg, Frankfurt a. M. Germany. References: Revilliod, P. (1917): Fledermäuse aus der Braunkohle von Messel bei Darmstadt.

Prepped by transfer method (Toombs, Harry; A.E. Rixon (1950). "The use of plastics in the "transfer method" of preparing fossils". The museums journal. 50: 105–107.) Palaeochiropteryx tupaiodon with partly preserved wing membrane and fur. As far as I know, four bat genera with a total of 8 species are known from Messel: Palaeochiropteryx tupaiodon and P. spiegeli, Archaeonycteris trigonodon and A. pollex, Trachypteron franzeni, Hassianycteris messelense, H. magna and Hassianycteris? revilliodi.

The largest bat in Messel is Hassianycteris magna with a wingspan of almost 50cm. Diagnosis from Russel & Sigé 1969, p. 124 (translated from French by oilshale): Diagnosis: size smaller than Palaeochiropteryx spiegeli. P3 relatively longer and narrower; protocortid high and acute; tubercles of lower molars higher and more acute; trigonid of M1 more compressed anteroposteriorly; talonid of M3 wider and higher relative to trigonid. Upper canine relatively taller, narrower and more pointed posteriorly at its base; heel of P³ narrower lingually, with its posterior margin oblique anterolingually; on M'-M², notch between mesostyle and parastyle deeper.
