... of the species of Eryma currently known from North America have been collected in Jurassic siliciclastic strata. The majority of these record the former presence of a seaway that extended from Borden Island, in the Canadian Arctic, to Utah, in the western part of the United States (Fig. 3); no spe- cies of this genus are known from the Jurassic of the Gulf Coast region. Strata of the Smithers Formation containing E. walkerae were originally part of the Stikine terrane of west- ern British Columbia, which was located in lower latitudes relative to the continent during the Triassic and earliest Jurassic (Tipper 1981;Smith ...

... Stenodactylina species are erected mostly on isolated chelae or carapaces (Feldmann et al., 2020). The few species are known from the Callovian to the Oxfordian (Feldmann et al., 2020;Charbonnier, 2019, 2021): S. walkerae (Feldmann and Haggart, 2007) (Bajocian-Callovian, Canada), S. burgundiaca (Crônier and Courville, 2004) (Callovian, France), S. insignis (Oppel, 1862) (Oxfordian, France), and S. shotoverigiganti Devillez and Charbonnier, 2021 (Oxfordian, UK).

The decapod crustaceans of Central European Russia have been the subject of studies since the nineteenth century, and the only species, Eryma quadriverrucatum Trautschold, 1866 (Erymidae), has been found in the Callovian to the Oxfordian of that region. The present paper discusses the new exceptional findings of Solenoceridae, Glypheidae, and Mecochiridae from the upper Callovian sites of the Ryazan Region. The previously reported presence of Archeosolenocera sp. is confirmed in detail; Glypheopsis aff. G. etalloni (Oppel, 1861) and Eumorphia sp. are noticed for the first time for this area. Modern identification of erymids is reported: Eryma aff. E. ventrosum (von Meyer, 1835), E. ornatum (Quenstedt, 1858), and Stenodactylina insignis (Oppel, 1862) are noted in addition to E. quadriverrucatum . These findings address the gaps in the fragmented knowledge about the decapod fauna of Central European Russia and exhibit a differentiation of the local Russian decapod assemblage from those of Western Europe. The decapod community of the Ryazan region is considered to be associated with soft substrates of upper sublittoral zone.
... Lobsters of the Erymidae Van Straelen, 1925, have been reported from many localities in North America, covering a stratigraphic range from the Lower Jurassic to Upper Cretaceous (see Feldmann et al. 2020: table 1). Based upon Feldmann et al. (2020), five species of erymid lobsters have been reported to date in Canada, as follows: Pustulina dawsoni (Woodward, 1900) from the Upper Cretaceous (Campanian) of Hornby Island (British Columbia); Enoploclytia mi nor Woodward, 1900 from the Upper Cretaceous (Campanian) of Hornby Island (British Columbia); Stenodactylina bordenensis (Copeland, 1960) from the Lower Jurassic (Sinemurian) of Borden Island (Northwest Territories); S. walkerae (Feldmann & Haggart, 2007) from the Middle Jurassic (Bajocian-Callovian) of British Columbia; and S. beardi Feldmann, Schweitzer & Haggart, 2020 from the Upper Cretaceous (Santonian-Campanian) of Vancouver Island (British Columbia). However, based upon Devillez & Charbonnier (2019: 4) S. bordenensis (= Ery ma bordenensis) must be assigned to Pseudoglyphea, as already suggested by Förster (1966). ...

... Node 19 (Clytiopsis + Lissocardia) is supported by two unambiguous synapomorphies: the simple gastro-orbital groove (4 1 ); the pseudochelate pereiopod 4 (35 1 ). Sometimes considered as erymids in the litterature (Van Straelen, 1928;FörSter 1966FörSter , 1967etter 2004;Feldmann & haGGart 2007;de GraVe et al. 2009;SChWeitzer et al. 2010), the systematic positions of Clytiopsis and Lissocardia remain uncertain. In amati et al. (2004) Clytiopsis was sister to a clade including Erymidae and Pemphicidae. ...
A morphological-based phylogenetic analysis of a total of 33 species: 27 fossil species from eight families recognized prior to this work (Chimaerastacidae, Clytiopsidae, Erymidae, Glypheidae, Litogastridae, Nephropidae, Pemphicidae, Uncinidae), and 6 extant species from four families recognized prior to this work (Astacidae, Enoplometopidae, Nephropidae, Stenopodidae) is proposed. The cladistic analysis demonstrates that the erymid lobsters should be included with the other clawed lobsters within the infraorder Astacidea. Among Astacidea, we observed the structure recalling the intercalated plate of erymids in the extant Enoplometopus reported by Schram & Dixon. In order to test Schram & Dixon’s hypothesis, we considered this structure as homologous to the intercalated plate. Our results suggest that the sharing of this character does not indicate close relationships between Enoplometopus and erymids. The erymid lobsters form a monophyletic group of six genera (Eryma, Enoploclytia, Palaeastacus, Pustulina, Stenodactylina, Tethysastacus) included in the superfamily: Erymoidea. The inclusion of a character recently identified, a delimited post-orbital area, in the morphological dataset led to the split of Erymoidea into two clades. This topology justifies a systematic rearrangement of erymid genera within two families: Enoploclytiidae fam.n., lacking a delimited post-orbital area (Enoploclytia, Pustulina), and Erymidae, showing a delimited post-orbital area. The Erymidae are also separated in two sub‒families: the simplicity of the carapace groove pattern of Tethysastacus justifies its placement within Tethysastacinae subfam.n., while Eryma, Palaeastacus and Stenodactylina form the Eryminae.
... The genus Pustulina is very rare and the specimens show some characteristics on their carapace recalling other erymid genera (an almost sinuous hepatic groove for example), that are absent in more recent species. Finally, we point out that only E. compressum, P. foersteri and Stenodactylina walkerae (Feldmann and Haggart, 2008) are reported outside Europe.

... Moreover, all the fossils of erymid lobsters reported in Early Jurassic were found in Western Europe and almost all of the specimens of the Middle Jurassic: Eryma compressum (Eudes-Deslongchamps, 1842) was reported from Iran (Förster and Seyed-Emami, 1982) and Morocco (Secrétan, 1984), and Palaeastacus foersteri (Feldmann, 1979) n. comb. and Stenodactylina walkerae (Feldmann and Haggart, 2008) were found in North America. So, the extra-European erymid faunas are largely unknown and it is impossible to say if these lobsters spread out from Europe at the beginning of the Jurassic or if the European fauna was the result of previous migrations of populations from other areas. ...
Erymid lobsters (Crustacea, Decapoda, Erymidae) are an important component of Mesozoic crustacean faunas in Europe, especially during the Jurassic. The 29 species reported from the Early and Middle Jurassic are the oldest found in Western Europe and North America, and constitute an important part of the evolutionary history of these lobsters. After the review presented here, 24 species are maintained within the genera Eryma Meyer, 1840 (7 species), Palaeastacus Bell, 1850 (5 species), Pustulina Quenstedt, 1858 (2 species) and Stenodactylina Beurlen, 1928 (9 species). All these species, with the exception of Eryma ventrosum (Meyer, 1835), have a new description and the diagnoses of the genera Eryma, Palaeastacus and Stenodactylina are emended. Four species are transferred to another genus: Palaeastacus numismalis (Oppel, 1862) n. comb., Palaeastacus foersteri (Feldmann, 1979) n. comb. and Stenodactylina guisei (Wright, 1881) were previously assigned to Eryma, and Stenodactylina spinosa (Étallon, 1861) n. comb. was previously assigned to Palaeastacus. Our study shows that Stenodactylina was the most diversified genus in Early-Middle Jurassic, but the fossils of Eryma are more common. Furthermore, Eryma compressum (Eudes-Deslongchamps, 1842) is the emblematic species of Erymidae Van Straelen, 1925 during the end of Early Jurassic and Middle Jurassic in Western Europe (Toarcian-Bathonian). This species includes now Eryma bedeltum (Quenstedt, 1858) in its synonymy. The genus Pustulina is very rare and the specimens show some characteristics on their carapace recalling other erymid genera (an almost sinuous hepatic groove for example), that are absent in more recent species. Finally, we point out that only E. compressum, P. foersteri and Stenodactylina walkerae (Feldmann and Haggart, 2008) are reported outside Europe.

... The only known Late Cretaceous erymid fauna of the Southern Hemisphere was found in the Campanian deposits of Madagascar (Secrétan, 1964;Charbonnier et al., 2012). Secrétan (1964) (Feldmann and Haggart, 2007) (middle Bajocianearly Callovian) and then no erymid is known between the Oxfordian and the Albian. At the end of the Early Cretaceous and in the Late Cretaceous, most of North American species (Enoploclytia gigantea Devillez et al., 2016, E. tumimana, E. wintoni, Palaeastacus kimzeyi, P. walkeri (Whitfield, 1883), Stenodactylina triglypta) occurred in the north of the Gulf of Mexico, which included the flooded part of the south of the United States (Texas, Louisiana, Mississippi, Alabama, Georgia, Florida). ...
The Erymidae Van Straelen, 1925 had a worldwide distribution during the Jurassic and the Cretaceous. Twenty-seven species among four genera were reported in the Late Cretaceous, but confusions in diagnoses have led to wrong generic identifications of many erymid species. In the light of recent clarifications of the diagnoses of erymid genera, the Late Cretaceous species are here reviewed. We recognize thirteen of them including three European species which benefit of new descriptions: Palaeastacus sussexiensis (Mantell, 1824), Enoploclytia leachi (Mantell, 1822) and Enoploclytia seitzi Glaessner, 1932. Furthermore, a comparison of the Late Cretaceous erymid fauna with that from the Early Cretaceous emphasizes some changes. A decrease in diversity on genus and species level is noted with the absence of Eryma Meyer, 1840 in the Late Cretaceous and the predominance of Enoploclytia M’Coy, 1849 (including almost half of the species). Despite the scarcity of the fossil record, our palaeobiogeographic interpretations led us to propose hypotheses about the provenance of North American populations in the end of Early Cretaceous and in Late Cretaceous: (1) their supposed absence since the Callovian (Jurassic) is due to collecting and/or reporting bias or (2) they were the result of migrations of European populations. Moreover, the report of a chela assigned to Stenodactylina cf. armata (Secrétan, 1964) in France confirms the existence of migration routes between European and Malagasy faunas during the Late Cretaceous.

Erymid lobsters (Crustacea, Decapoda, Erymidae) are relatively common and abundant in Jurassic rocks (c. 70 species) but are far less common in the Early Cretaceous with about 20 species only listed in Europe, North America, South America, Australia, Antarctic, Japan, and Madagascar. A study of the twelve species of erymid lobsters from the Early Cretaceous of Europe (France, United Kingdom) is here presented. Based on new observations, the concepts of some erymid genera are updated and new diagnoses are proposed for Eryma Meyer, 1840, Enoploclytia M’Coy, 1849, Palaeastacus Bell, 1850, Pustulina Quenstedt, 1857, and Stenodactylina Beurlen, 1928, including carapace groove pattern, first pereiopods and also a new structure – the post-orbital area – located in front of the cephalic region. The new genus Tethysastacus n. gen. is erected with Tethysastacus tithonius n. comb. (Valanginian, France) as type species. Five new species are described: Eryma vocontii n. sp. (Albian, France), Enoploclytia augustobonae n. sp. (Barremian, France), Enoploclytia gigantea n. sp. (Albian, Texas), Pustulina occitana n. sp. (Berriasian, France), and Pustulina colossea n. sp.

A synthesis of our current knowledge of erymoid lobsters is presented. The superfamily Erymoidea includes two families, Erymidae Van Straelen, 1925 and Enoploclytiidae Devillez, Charbonnier & Barriel, 2019, together encompassing 81 species within six genera. Our examination of the palaeobiodiversity of this group and its evolution has revealed some variations through the Mesozoic with three important peaks, at the boundaries of: 1) Lower-Middle Jurassic; 2) Middle-Upper Jurassic; and 3) Lower-Upper Cretaceous. Whereas the origin of the first peak remains poorly known, the two others coincide with major modifications of the environment: the development of the European Jurassic carbonate platforms and the development of the European Chalk Sea and the partial flooding of North America during the mid- and Late Cretaceous. In addition to a notable peak of diversity, the Cretaceous is an important time interval in the evolutionary history of erymoids because the Early Cretaceous represented a long period of relatively low diversity and during the Late Cretaceous a strong decline of erymoid faunas is observed in Europe. However, the erymoids had already attained a worldwide distribution during the Early Cretaceous with occurrences in all oceans of the time. The analysis of the palaeobiogeographic distribution of these lobsters suggests the presence of important migratory paths, which probably favoured their spread and faunal exchanges between different areas across the globe.
Two well preserved specimens of nephropid lobster from the Late Cretaceous (late Campanian) Point Loma Formation in San Diego County, California, form the basis of description of a new species of Hoploparia. The occurrence represents the southernmost fossil record of macrurans along the Pacific coast of North America and it is only the third fossil lobster from California.
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.
The description of a new species of an erymid lobster, Stenodactylina beardi, from the Upper Cretaceous Haslam Formation of the Nanaimo Group on Vancouver Island, British Columbia, Canada, brings to fifteen the number of Erymidae in North America. The species are arrayed within five genera based upon configuration of carapace groove morphology, resulting in two new combinations, Stenodactylina bordenensis (Copeland, 1960) and S. foersteri (Feldmann, 1979). The new species exhibits for the first time a male pleopod and accessory structures within Erymoidea. We also provide a list of the North American species of Erymoidea.
