COMMENTS Three of the specimens figured are in ventral view ( Fig. 9 C-G), allowing the observation of nicely preserved details such as the mandibles exhibiting sharp triangular teeth of uneven size (specimen MNHN.F.GG2004/8220; Fig. 9D, E ). Indeed, the preservation is usually excellent: the antennae, antennules and eyestalks of the specimens MNHN.F. A33545 and GG2004/8218 are clearly visible and they exhibit between eight and ten pereiopods. The dorsally preserved specimen MNHN.F.B13439 ( Fig.9H ) is also well-preserved and evidences delicate details on the carapace (branchiocardiac, postcervical and cervical grooves), telson (ponctuations and carinae).The other specimen ( A33501 ; Fig. 9B ) present some calcite bundles on the left chela.

A33501 from Solnhofen; C , specimen MNHN.GG.2004/8218 from Solnhofen area;this specimen was referred to as coming from Pappenheim;since there are no Solnhofen Lithographic Limestones there, while many traders lived there, this specimen was probably purchased in Pappenheim; D , E , specimen MNHN.GG.2004/8220 from Solnhofen, natural light ( D ) and UV light ( E ); F , G , specimen MNHN.F.
