1 Zitteliana A 54 (2014) 83 A new caridean shrimp (Crustacea: Decapoda: Dendrobranchiata) from the Upper Jurassic Solnhofen Lithographic Limestones of Schernfeld (South Germany) Zitteliana A 54, München, Manuscript received ; revision accepted Norbert Winkler D Stahnsdorf, Germany ISSN X Abstract A new genus and species of caridean shrimps, Occultocaris frattigianii nov. gen. et sp., is described from the Upper Jurassic Solnhofen Lithographic Limestones of Schernfeld near Eichstätt (Lower Tithonian, Hybonotum Zone). It differs from other genera of carideans primarily in the armature of the rostrum in combination with the shape of the chelae of the first and second pereiopods. Key Words: Caridea, Solnhofen Lithographic Limestones, Tithonian. Zusammenfassung Eine neue Gattung und Art von Garnelen aus der Unterordnung Caridea, Occultocaris frattigianii nov. gen. nov. sp., wird aus den oberjurassischen Solnhofener Plattenkalken von Schernfeld bei Eichstätt beschrieben (Unter-Tithonium, Hybonotum-Zone). Sie unterscheidet sich von anderen Gattungen der Caridea in erster Linie in der Bezahnung des Rostrums in Kombination mit der Gestalt der Scheren der ersten und zweiten Pereiopoden. Schlüsselwörter: Caridea, Solnhofener Plattenkalke, Tithonium 1. Introduction The decapod infraorder Caridea Dana, 1852 is comprised of 3438 extant species in 389 genera (De Grave & Fransen 2011). Moreover, 52 fossil species of carideans are listed in 33 genera (Schweitzer et al. 2010). The Upper Jurassic lithographic limestones of the region of Eichstätt represent an important source of well preserved fossil assemblages. Besides vertebrates, invertebrates as well as plants are preserved in the limestones; however, apart from mass occurrences of the planktonic crinoid Saccocoma tenella these limestones are relatively poor in fossils. Among the invertebrates, natantian shrimps play an important role (Röper et al. 2000). Within the natantians, the carideans are very diverse. Among them, only the well-known Hefriga serrata Münster, 1839 appears to be quite frequent (Schweigert & Garassino 2003). In addition to this long since known fossil caridean, several other taxa from this area have recently been added, including Schmelingia wulfi Schweigert, 2002, Buergerocaris psittacoides Schweigert & Garassino, 2004, Udora koschnyi Schweigert & Garassino, 2004, Pleopteryx kuempeli Schweigert & Garassino, 2004, Harthofia blumenbergi Polz, 2007, Harthofia bergeri Polz, 2007, Alcmonacaris winkleri Polz, 2008, Hefriga rogerfrattigianii Schweigert, 2011, Hefriga norbertwinkleri Schweigert, 2011, Harthofia polzi Schweigert, 2011, and Schernfeldia schweigerti Winkler, 2013 (Münster 1839; Schweigert 2002; Schweigert & Garassino 2004; Polz 2007, 2008; Schweigert 2011; Winkler 2013). Most of these new genera or species are very rare or known only from single specimens. The bulk of the decapod fossils are represented by exuviae in various stages of decay (Schweigert 2011). This paper describes a new natantian genus based on several exquisitely preserved fossils. 2. Material and methods The description is based on 12 specimens: S1 Holotype (CL 11.0, TL 52.8, L Schernfeld); S2 Paratype (CL 8.5, TL 40.5, L Wintershof); S3 (CL 10.0, L Schernfeld, coll. Winkler, Stahnsdorf); S4 (CL 6.5,

Winkler, Stahnsdorf); S7 (CL 11.5, L Birkhof, coll. Frattigiani, Laichingen); S8 (CL 6.5, TL 33.0, L Eichstätt, coll. Frattigiani, Laichingen); S9 (CL 10.0, L Eichstätt, coll. Resch, Eichstätt); S10 (CL 11.5, L unknown, coll. Felthaus, Vlotho); S 11 (CL 10.5, L unknown, coll. Felthaus, Vlotho); S12 (CL 11.5, L Schernfeld, coll. Winkler, Stahnsdorf). The total length of the specimens range between 29.9 mm (S4) and 53.0 mm (S10). The holotype comes from the Upper Jurassic Solnhofen Lithographic Limestones (Eichstätt Formation; Lower Tithonian, Hybonotum Zone) in southern Germany. The specimen occurs on a limestone slab that is 9 mm thick. Specimen preparation was carried out with a vibrograph and various needles and scrapers. Because the sclerotisation of the exoskeleton of crustaceans preserved in litographic limestone brightly fluoresces, fluorescence was used in the analysis of the fossil. In this way even the most delicate features, which otherwise would not or only barely be discernible, could be observed and adequately documented photographically. For the documentation of the holotype specimen, a macro-fluorescence set up was used (Haug et al. 2011). Digital images were taken with a Canon Rebel T3i camera with a MP-E 65mm macro lens. Light was provided by three evenly distributed LED torches, each equipped with a cyan filter. A red filter was mounted onto the lens. With this, mainly the light emitted from the fossil (roughly of orange colour) was detected by the camera. Processing of images followed Haug & Haug (2011); only the red channel is informative (other channels originate from scattered light), the image is then desaturated and the histogram optimised. Several images were stitched together using the Photomerge function of Adobe Photoshop CS3 to produce a high-resolution image. The paratype and S4 were documented on a Keyence BZ-9000 fluorescence microscope. A 2x objective was used, resulting in a magnification of approximately 20x. An excitation wavelength of 543 nm (green) was used. To overcome the limited depth of field a stack of images was recorded and fused into a single sharp image. Several of these images (of different image details) were stitched to yield a high-resolution image (e.g., Haug et al. 2008, 2009, 2011).

Systematic palaeontology Diagnostic characters of the Caridea: The classification of Caridea follows McLaughlin (1980) and is largely based on extant taxa. All members of Caridea exhibit the following complement of external features: (1) the second pleonal pleura overlap the pleura of both the first and third pleomeres; (2) the first two pairs of pereiopods chelate (except in Procarididae); (3) pereiopods III, IV and V achelate; (4) the rostrum is extremely variable in both length and armature; (5) antennular peduncle with three articles; (6) a telson bearing several small movable spines. Mouthpart morphology is usually difficult to assess in fossil shrimps and prawns from the Solnhofen Limestones due to the mostly lateral embedding of fossils. The classification to the superfamily Bresilioidea predicates on the key to Recent Superfamilies of Caridea, which is based largely on the form of the anterior pairs of pereiopods (Chace & Manning 1972; modified from Holthuis 1955). However, Martin & Davis (2001) regard the superfamily Bresiloidea as an admittedly artificial taxon.

Uropods with distinct protopod ending in a sharp point; uropodal endopod as long as exopod, lacking teeth; uropodal exopodites with diaeresis (Pl. 1, Fig. 4). 4. Comparisons The number of rostral teeth is of great importance in the discrimination of the different genera and species of Caridea (Holthuis 1951), but additional characters may also be significant for the identification of new fossils (e.g., von Rintelen & Cai 2009). A comparison of the new form described in this paper with other fossil caridean genera (based on the original descriptions) shows that: (1) Besides O. frattigianii the following genera of fossil carideans posses a completely unarmed rostrum: Udora koschnyi Schweigert & Garassino, 2004 (Schweigert & Garassino 2004), and Schmelingia wulfi Schweigert, 2002 (Schweigert 2002) from the Upper Jurassic, as well as Bannikovia maikopensis Garassino & Teruzzi, 1996 (Garassino & Teruzzi 1996) from the Lower Miocene, and Yongjicaris zhejiangensis Garassino et al., 2002 (Garassino et al. 2002) from the Lower Cretaceous, as well as Morscrangon acutus Garassino & Jakobsen, 2005 (Garassino & Jacobsen 2005) from the Lower Eocene. However, all these taxa clearly differ from O. frattigianii in the shape of the pereiopods. The shape and the armature of the rostrum of O. frattigianii is of great consistency since juveniles show the same rostrum-features as the adults; (2) The first pereiopods of O. frattigianii are equipped with broad chelae and the first pereiopod is slightly shorter than the second. A similar combination of features does not occur in any other fossil caridean; (3) O. frattigianii superficially resembles the Late Jurassic Hefriga serrata Münster, 1839 (Münster 1839), the type species of the genus Hefriga. However, there are several morphological details that discriminate O. frattigianii from Hefriga. Firstly, O. frattigianii differs from H. serrata in the armature of the rostrum (H. serrata with about 10 dorsal teeth). Secondly, the surface of the carapace and pleon of H. serrata show a delicate pattern of subparallel striae, whereas the surface of O. frattigianii shows inconspicuous shallow punctations. Thirdly, the shape of the chelae of PI and PII is distinctly different from those of H. serrata; (4) O. frattigianii differs from all other fossil carideans [i.e. Pleopteryx kuempeli Schweigert & Garassino, 2004, Buergerocaris psittacoides Schweigert & Garassino, 2004 (Schweigert & Garassino 2004), Alcmonacaris winkleri Polz, 2008 (Polz 2008), Schernfeldia schweigerti Winkler, 2013 (Winkler 2013), and the representatives of Harthofia Polz, 2007 (Polz 2007; Schweigert 2011)] in the armature and the shape of the rostrum, as well as in the shape of the pereiopods. Occultocaris frattigianii exhibits several morphological details that clearly distinguish this taxon from all earlier described fossil caridean genera, and we propose therefore a new genus and species to include the specimens with their unique combination of characters. Although the new genus Occultocaris has well-defined special characters, it is impossible to assign it to a family or superfamily with certainty. According to Chace & Manning (1972), however, it may be possible to assign this new taxon to the superfamily Bresilioidea Calman, 1896 because of the fact that the first pereiopods are stouter and slightly shorter than the second pereiopods.
7 5. Palaeoecology and taphonomy of Occultocaris frattigianii The strong and broad chelae strongly suggest that O. frattigianii was a predator or scavenger (Schweigert & Garassino 2004). The rather long antennae probably was equipped with a variety of different receptors in order to detect and recognise nearby objects (Raabe & Raabe 2008). The co-occurrence of various ontogenetic stages of a single palaeobiospecies (here: O. frattigianii) may be a result of autochthonous lifestyle, or at least to a habitat in close proximity to the burial place (Schweigert 2007). Six of twelve specimens included in this study come from Schernfeld, four others from nearby localities. Very recently an additional specimen was discovered from Schernfeld (coll. Hoffmann, Spalt). The relative frequency of this taxon in a small area in the northern vicinity of Eichstätt corroborates the hypothesis that the place of burial was not far away from the original habitat of this shrimp (Schweigert 2007). Moreover, O. frattigianii probably was not rare in the palaeoecosystem, but has not been recognised previously because it occurs together with other superficially similar taxa, and the first and second pereiopods, which are the most important distinguishing character, are not normally discernible. The taphonomic circumstances that caused the typical preservational state of the O. frattigianii specimens are comparable to those of many eryonids. Whereas at least one chela of O. frattigianii s PI and/or PII is turned up, the pereiopods I of many eryonids are pointing backward. This was caused by the heavy chelae, which usually hang down from the drifting exuvia, became cought in the seafloor first (Schweigert 2007). Acknowledgements My sincere thanks go to Dr. G.
