Antrimpos speciosus Münster, 1839  

( Fig. 3 View FIG )

STUDIED MATERIAL. — Charbonnier & Garassino (2012) mentioned six specimens: three specimens from Solnhofen (MNHN.F. A33519 View Materials , A33548 View Materials , R03502 View Materials );   two specimens from Eichstätt ( MNHN.F. A33504, B13465) and one specimen from an unknown locality ( MNHN. GG.2004/8086). Collections Boué, de Roissy, Hoffstetter, Manchester Museum, d’Orbigny   .

COMMENTS

Specimen MNHN.F. A33504 View Materials ( Fig.3 View FIG A-C) shows a well-preserved rostrum and a well-marked hepatic spine, while specimen A33519 View Materials ( Fig.3G, H View FIG ) shows evidence of preserved muscle fibres near somites 1 and 2 (see also Briggs et al. 2005). For comparison, specimens from the Carnegie Museum of Natural History (CM-33420; from Robalino et al. 2016; Fig. 3D, E View FIG ) and from the private collection of Roger Frattigiani (Laichingen, Germany; figured in Schweigert 2015: fig. 568 and Fig. 3F View FIG ) are also illustrated.

Antrimpos undenarius Schweigert, 2001   ( Figs 4 View FIG ; 5 View FIG )

TRANSLATION OF THE DIAGNOSIS (from Schweigert 2001). — Largesized species of the genus Antrimpos   , rostrum with 11 dorsal spines, the posterior one [= hepatical spine] being separated from the others, and one ventral spine located just before the foremost dorsal spine. Long propodite on P3.

STUDIED MATERIAL. — Charbonnier & Garassino (2012) did not mention this species. Nine specimens MNHN.F. A06834 View Materials , A49608 View Materials , A49609 View Materials , A49610 View Materials , A49615 View Materials , A49616 View Materials , A49622 View Materials , A49623 View Materials and A49624 View Materials from Nusplingen were re-discovered in the Collection d’Orbigny. All these specimens are labelled “Nusplingen, Mr Béroldingen, 13 e ” ( Fig. 4A View FIG ). The family von Beroldingen is an old family of nobles originating from Switzerland; Baron Franz Coelestin von Beroldingen (1740-1798) was known as a mineral and fossil collector and after his death, his nephew, Count Joseph Ignace von Beroldingen (1780-?), sold his mineral collection to the London museum ( British Museum of Natural History 1904). In our case, “Mr Béroldingen” refers to Paul Ignaz Josef Graf von Beroldingen (1804-1875), another nephew of Baron von Beroldingen, who offered the Antrimpos   specimens from Nusplingen to Alcide d’Orbigny. von Beroldingen probably got them by exchanging fossils with Oscar Fraas (1824-1897) as the two of them knew each other. Indeed, in a letter from 1863, “Mr Béroldingen” mentioned several fossils from the Tertiary of Swabia, including the Jurassic taxon Squatina acanthoderma from Nusplingen, which was described by Oscar Fraas in 1855 ( Mayer 1976). Number “13 e ” refers to the thirteenth geological stage of d’Orbigny, which is the Oxfordian. Additional specimens of A. undenarius   coming from the SMNS collection are presented in Fig. 5 View FIG for comparison.  

COMMENTS

According to Schweigert (2017), Antrimpos undenarius   is the most abundant prawn of the Nusplingen Plattenkalk. The d’Orbigny specimens are characteristically preserved by a coating made of iron oxides ( Figs 4B, D, E, H View FIG ; 5 View FIG A-E) and embedded in relatively coarse lithographic limestones. The orientation of the corpses (pleon in lateral view and carapace in dorso-ventral view, as in Figs 4H View FIG ; 5 View FIG A-C, E) is also characteristic of the fossil prawns from Nusplingen. Thus, the preservation in complete dorsal view, as for A49610 View Materials ( Fig. 4D View FIG ) and SMNS 66122 ( Fig. 5F View FIG ) is rather rare. Furthermore, the preservation in 3D of the rostrum is particularly remarkable on specimens SMNS 80482 and SMNS 66122 ( Fig. 5C, F View FIG ). On specimens housed at the MNHN, the diagnostic anatomical characters of the species are poorly preserved and observed alternatively in several specimens ( Fig. 4C, E, G View FIG ). For instance, the rostrum with numerous dorsal teeth ( Fig. 4G View FIG ), the strong hepatic spine, the hepatic ridge, the median lateral processes on s1-s3 are typical of Antrimpos   . The large size of the specimens is compatible with A. undenarius   .
