Archaeonycteris trigonodon Revilliod, 1917

Middle Eocene


Messel near Darmstadt




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 much rarer and somewhat larger - the wingspan is about 37cm. The largest bat in Messel is Hassianycteris magna with a wingspan of almost 50cm.
