“…Moreover, the ornamentation of S. strambergensis is homogeneous -only made of coarse tubercles -contrary to other species, except S. armata and S. triglypta. diAgnosis by Devillez et al (2018). -Fusiform intercalated plate; wide, deep cervical groove, joined to dorsal margin and to antennal groove; long, wide gastro-orbital groove originating as a median inflexion of cervical groove, delimiting two gastroorbital lobes; sinuous postcervical groove, joined to dorsal margin and to hepatic groove, with ventral extension at carapace mid-height; short branchio-cardiac groove, interrupted in upper part of carapace, joined to dorsal margin, not joined to postcervical groove; concavo-convex hepatic groove, joined to cervical groove; prominent ω and χ bulges; inferior groove convex posteriorly, joined to hepatic groove; carapace with heterogeneous coarse ornamentation; massive globose P1 propodus, rounded in transversal section; long and thin P1 fingers (straight in dorsal view); occlusal margins armed with sharp and slender tooth; P1 merus with strong, prominent distal process at extern side of its ventral extremity.…”

Erymoid lobsters (Crustacea, Decapoda, Erymoidea) are an important component of Mesozoic crustacean faunas in Europe, especially during the Jurassic. With 36 species reported, these lobsters reach their highest diversity during the Late Jurassic. After the review presented here, 23 species belonging to Eryma Meyer, 1840 (11 species), Palaeastacus Bell, 1850 (2 species), Pustulina Quenstedt, 1857 (2 species) and Stenodactylina Beurlen, 1928 (8 species) remain valid. One new species is described: Stenodactylina shotoverigiganti n. sp., and Eryma pseudoventrosa Beurlen, 1928 is integrated to Stenodactylina. We also notice the oldest representative of Enoploclytia M'Coy, 1849, known by a single specimen unidentified at specific level. Eryma ventrosum (Meyer, 1835) is the most common species in Western Europe, and may be seen as emblematic of the Middle-Late Jurassic. Moreover, the lithographic limestones of Germany yield an exceptionally diversified erymoid fauna, with four genera (Eryma, Palaeastacus, Pustulina, Stenodactylina) and 11 species listed. All the Late Jurassic representatives of Palaeastacus were found in this lithology. Finally, the examination of some specimens allows the observation of the strong effects of the decortication on the ornamentation of the erymoids and the resulting taxonomic issues.

“…More complete specimens, with the carapace and corresponding chelae preserved, are only found when conditions were favourable or within concretions (e.g., Hyžný et al, 2015). At generic level, erymid lobsters are distinguished mainly by their characteristic carapace groove pattern (Devillez & Charbonnier, 2017, 2020Devillez et al, 2018), while chela shape is less characteristic, at least in Eryma s. str. In the latter, there is one clade that has chelae with relatively short fingers; this group is distinguished from another with strikingly longer, straight fingers, although the groove pattern of the carapace is the same.…”

Two new species of Late Jurassic erymid lobsters, Stenodactylina devillezi sp. nov. and Stenodactylina geigerae sp. nov., are described on the basis of isolated, but well-preserved chelipeds from the upper Kimmeridgian of Swabia and the lower Tithonian of Bavaria, respectively. The incomplete nature of the material indicates that these lobsters were not autochthonous elements of the Plattenkalk lagoons, but resulted from predation in nearby shallow-water settings.Izvleček V prispevku predstavljamo dve novi vrsti zgornjejurskih jastogov iz družine Erymidae, to sta Stenodactylina devillezi sp. nov. in Stenodactylina geigerae sp. nov. Novi vrsti sta opisani na podlagi izoliranih, vendar dobro ohranjenih škarnikov iz zgornjega kimmeridgija Švabske in spodnjega tithonija Bavarske. Slabša ohranjenost primerkov kaže, da tovrstni jastogi niso bili avtohtoni prebivalci zgornje jurskih lagun, ampak so verjetno poseljevali bližnja plitvovodna okolja.

“…The decapod crustaceans from the Jurassic deposits of Normandy were reported since the nineteenth century by some pioneers such as Eudes-Deslongchamps (1835, 1842) Morière (1864, 1882), Hée (1924), and Van Straelen (1925) (see historical synthesis by Gendry 2020). In the 2000s, new studies were carried out on occasional but important discoveries in the Early Jurassic (e.g., hermit crabs: Schweigert et al 2013), Middle Jurassic (e.g., isopods: Guinot et al 2005; homolodromioid crabs: Fraaije et al 2013; galatheoid anomurans: Fraaije et al 2019; erymid lobsters: Devillez & Charbonnier 2019), and Late Jurassic (e.g., erymid and glypheid lobsters: Devillez et al 2018; Charbonnier et al 2013; Chény et al 2023). The littoral outcrops along the English Channel (e.g., Vaches Noires cliffs) are particularly favorable to collect fossil crustaceans by amateur palaeontologists and scientists.…”

The Late Jurassic (late Oxfordian) fauna from Cricqueboeuf (Normandy, France) is remarkable for its three-dimensionally fossilized crustaceans in carbonate and phosphate nodules, some even preserving eyes and ommatidia network. The crustacean fauna includes four species assigned to the Mecochiridae (Meyeria hurtrelleorum n. sp.), Glypheidae (Glypheopsis trouvillensis), and Erymidae (Eryma ventrosum, Enoploclytia sp.). A quantitative analysis based on 191 specimens shows that the fauna was dominated by Eryma ventrosum (46.6% of specimens) and Meyeria hurtrelleorum n. sp., (40.3%), which makes it unique in the fossil record of the Jurassic crustacean assemblages. Meyeria hurtrelleorum n. sp. is one of the oldest occurrences of the genus and its abundance at Cricqueboeuf is outstanding. The palaeoenvironment is interpreted as subtidal mud flats, where the soft substrate was favorable to the settlement and burrowing of both glypheid, mecochirid, and erymid lobsters. Most of the specimens may actually have been preserved directly inside their own burrow, ultimately infilled by reworking of the muddy bottom during detrital inputs.
