Cyrtopone is an extinct genus of ants in the formicid subfamily Ponerinae described from fossils found in Europe.

[1] Along with other well preserved insect fossils, the Cyrtopone specimens were collected from layers of the Lutetian Messel pit World Heritage Site.

The area is a preserved maar lake which initially formed approximately 47 million years ago as the result of volcanic explosions.

[2] At the time of description, the four holotype specimens were preserved in the Senckenberg Research Station Messel fossil collections.

The fossils were described by Gennady Dlussky and Sonja Wedmann in a 2012 paper on the poneromorph ants of Messel, with the genus and four species named in it.

[1] Cyrtopone is one of five extinct genera from three subfamilies which have species described from Messel Formation fossils by Dlussky and Wedmann in 2012.

The node shaped petiole is shorter than the height, with a helcium that projects of the front face of the gasteral segment.

[1] The only C. curiosa fossil is of a wingless gyne preserved in profile view with a body about 7.5 mm (0.30 in) long.

The winged gyne is a dorsal impression showing distinct sculpturing on the head and scutum made of longitudinal ridges.
