038987A6F305FF96EEC163105A1EF1E5.taxon	description	DESCRIPTION See Charbonnier et al. (2013). Glypheopsis trouvillensis was described based upon one isolated carapace, which is probably a moulted specimen. Two new specimens (MPV 2013.1.146.1, 2) allow us to add some morphological details previously not provided in the original description. Pleon Subrectangular s 1 - s 5 equal in size, with smooth tergum and pleuron; rounded s 1 - s 5 pleura; s 2 - s 5 pleura with marginal carina limited by a groove. Thoracic appendages Partially preserved P 1 lacking distal extremities (carpus, propodus, and dactylus); P 2 preserves only the subsquare basis; P 3 - P 5 preserve basis, ischium, and incomplete merus; dorsal margin of subsquare P 1 basis with one spine at level of ischiobasal articulation; subtriangular P 1 ischium strongly enlarged at level of ischiomeral articulation; subrectangular P 1 merus; smooth outer surface of P 1 ischium and merus; dorsal and ventral margins of P 1 ischium and merus covered by spines arranged in parallel rows; elongate P 3 merus with smooth outer surface and spiny dorsal and ventral margins. Ornamentation of carapace Charbonnier et al. (2013: 154) described the ornamentation of the branchial region of the carapace as made by pits dorsally and tubercles medially and ventrally and a tuberculate pterygostomial region. Some additional specimens (MPV 2013.1.146.1 - 9, 11, 13 - 15, 19 - 21, IGR-PAL- 153416, 153417) show that the ornamentation of the branchial region is more complex with the ventral area covered by small pits, the median area by small tubercles located inside pits, and the dorsal area by large pits.	en	Charbonnier, Sylvain, Garassino, Alessandro, Gendry, Damien, Devillez, Julien, Picot, Laurent (2023): The decapod crustacean fauna from the Late Jurassic of Cricqueboeuf, Normandy (France).

038987A6F305FF96EEC163105A1EF1E5.taxon	discussion	DISCUSSION The postcervical groove joining dorsally and ventrally to branchiocardiac groove, the presence of the cardiac and intercervical grooves and the absence of the gastro-orbital groove in additional specimens are all diagnostic characters of Glypheopsis. They are assigned to G. trouvillensis because they share with the holotype the three spiny cephalic carinae and the ornamentation of cephalic, cardiac, and branchial regions. Mainly, the ornamentation of the branchial region with a progressive gradation from ventral tubercles to dorsal pits is very typical of G. trouvillensis. We add all additional specimens collected in a fossiliferous locality nearby the type locality.	en	Charbonnier, Sylvain, Garassino, Alessandro, Gendry, Damien, Devillez, Julien, Picot, Laurent (2023): The decapod crustacean fauna from the Late Jurassic of Cricqueboeuf, Normandy (France).

038987A6F307FF98EF5062955B36F1E5.taxon	discussion	DISCUSSION The mecochirid lobsters include four genera, Atherfieldastacus Simpson in Robin et al., 2016, Huhatanka Feldmann & West, 1978, Mecochirus Germar, 1827, and Meyeria M’Coy, 1849 (junior synonym: Jabaloya Garassino, Artal & Pasini, 2009). Based on Robin et al. (2016) and Charbonnier et al. (2021: 4), the studied specimens show morphological characters typical of Meyeria: carapace groove pattern with elongate and wide cardiac groove joined to dorsal margin (short cardiac groove joined to dorsal margin in Atherfieldastacus; extremely short and not joined to dorsal margin in Mecochirus), subcircular hepatic groove, and short inferior groove not joined to ventral margin (joined to ventral margin in Atherfieldastacus; absent in Mecochirus); carapace with ogival cross section (bevelled sublanceolate in Atherfieldastacus; ogival in Mecochirus). Huhatanka exhibits a very simple carapace groove pattern and a carapace without branchial carinae, very different from the Cricqueboeuf specimens. Finally, the absence of the branchial carinae, diagnostic character of Atherfieldastacus (e. g. GonzálezLeón et al. 2014), allow us to assign confidently the studied specimens to Meyeria. Based on Charbonnier et al. (2021: 4), Meyeria includes nine species (see above-mentioned list), mostly restricted to the Early and Late Cretaceous. Only M. aragonensis (Garassino, Artal & Pasini, 2009) is known to date from the Oxfordian of Jabaloyas (Teruel, Aragón, Spain). Based on Garassino et al. (2009: 200, 201), the cephalic region with just one carina (gastro-orbital carina), regions of carapace covered by pits, the spiny ventral margins of s 2 - s 5 pleura, and the spiny outer margin of the uropodal exopod rule out the belonging of the studied specimens of this species. Charbonnier et al. (2013: 278) assigned Glyphea serratosae from the Jurassic of Buñol (Valencia, Spain) to Meyeria for the absence of the gastro-orbital groove and the elongate wide cardiac groove. As discussed by these authors, the age of this species is still controversial. Dupuy de Lôme & de la Revilla (1956) reported an indeterminate Jurassic age for the fossiliferous locality, whereas Vía (1976) proposed a Middle Jurassic age. Later, Solé & Via (1989) proposed a Late Jurassic age. Finally, Artal et al. (2008) returned to the Jurassic sensu lato. Though the age could be controversial, M. serratosae represented the only second species of the genus known to date from the Jurassic. Based on Dupuy de Lôme & de la Revilla (1956: 6), the subtriangular s 2 pleuron rule out the assignment of the studied specimens to this species. In conclusion, M. hurtrelleorum n. sp. is described to accommodate the studied specimens, representing for the genus the third report from the Jurassic and the second one from the Late Jurassic.	en	Charbonnier, Sylvain, Garassino, Alessandro, Gendry, Damien, Devillez, Julien, Picot, Laurent (2023): The decapod crustacean fauna from the Late Jurassic of Cricqueboeuf, Normandy (France).

038987A6F30CFF9FEF6F64305A08F11A.taxon	description	DESCRIPTION AND DISCUSSION Devillez & Charbonnier (2021: 34, 36) provided an updated and very complete description of Eryma ventrosum. The specimens from Cricqueboeuf show the fusiform intercalated plate typical of the erymid lobsters and a carapace groove pattern typical of Eryma: cervical groove, strongly inclined dorsally, joined to dorsal margin and to antennal groove; short gastro-orbital groove, originating as a slight median inflexion of the cervical groove; postcervical groove joined to branchiocardiac groove at carapace mid-height; branchiocardiac groove usually strongly inclined, joined to the posterior extremity of hepatic groove; hepatic groove concavo-convex, joined to cervical groove; inferior groove convex posteriorly, joined to hepatic groove and to ventral margin, inflated pleural basis. The specimens from Cricqueboeuf have a cervical groove slightly inflected, a short gastro-orbital groove, slightly curved postcervical and branchiochardiac grooves, joined at carapace mid-height, a ventral extension of the postcervical groove, an inflated ω area, a dense, fine ornamentation made of tubercles and crescent-shaped depressions, orbital and antennal rows of tubercles, elongated P 1 chelae with a subrectangular propodus which is compressed dorso-ventrally, bearing long thin fingers, progressively curved inward, and armed with numerous teeth. In addition, some specimens show rounded stalked eyes with a well-preserved framework of subsquare ommatidia (Fig. 8 B, D-F). All these morphological characters are typical of E. ventrosum, which is well-known in the Callovian-Oxfordian deposits of Normandy (Devillez & Charbonnier 2021).	en	Charbonnier, Sylvain, Garassino, Alessandro, Gendry, Damien, Devillez, Julien, Picot, Laurent (2023): The decapod crustacean fauna from the Late Jurassic of Cricqueboeuf, Normandy (France).
