SPECIES NAME:  Pseudosirex elegans (Wood wasp)

Order Hymenoptera, Genus Pseudosirex

GEOLOGICAL AGE: Upper Jurassic
(150 million years old)

STRATIGRAPHIC FORMATION: Solnhofen Plattenkalk (limestone)

LOCATION: Eichstatt, Bavaria, Germany

DESCRIPTION:  This is an exquisitely preserved fossil of the Jurassic era insect, the Wood wasp preserved within the world-famous Solnhofen limestone of Eichstatt, Germany.  While not amongst the rarest fossilized specimens of the Solnhofen Plattenkalk, truly well-preserved specimens such as the one presented here for your perusal are very uncommon. The Hymenoptera are insects possessing pairs of skin-like wings, with the anterior pair larger than the posterior. Bees, ants and wasps are important members of this Order. Females (such as this specimen) exhibit an ovipositor.  Since the Plattenkalk limestone of Solnhofen have yielded only an extremely limited number of hymenoptera, this specimen is highly desirable for the discerning collector.  Pseudosirex is subdivided in the plattenkalks into one larger and one smaller species, with the family relationships associated with the wood wasps, of which one species, Sirex is still alive to this day. The exquisite preservation as noted in this specimen derives from the anoxic environment of the seas in which it came to rest and the finely grained limestone matrix within which this fossil was preserved, which captured exquisite detail, including at times soft body parts, poorly mineralized skeletons and integument (skin and feather impressions). 

This fossil is well-situated and centered upon the matrix in the dorsal posture and is complete.  The head with eyes and antenna are beautifully preserved, as are the thorax and abdomen, with ovipositor well-defined. The wings are exquisite in their detail, with venations discernible, and with bilateral symmetry of the wings apparent. Several legs are observed to arise from the thorax.  The golden tinge of the matrix beautifully highlights this exquisite and rare specimen which would add greatly to a collection of rare, Jurassic era insect fossils of the world.
