“…5A). Abundant pyrite has also been observed in specimens of Atherfieldastacus magnus from the Aptian of Colombia (González-León et al, 2016). This suggests that localities around the world, where A. magnus is abundant, may represent anoxic events that either killed the lobster populations and/or preserved the remains of this globally distributed species during the Early Cretaceous.…”

“…4, 5). Previously, such features had been recorded by Feldmann & Tshudy (1987), Vega et al (1994) and González-León et al (2016, 2018, both for other species and for Atherfieldastacus magnus, but recrystallised cuticles do not show clear layers (González-León et al, 2016).…”

“…At most localities, cuticle structure is obscured by mineral replacement of the original carbonate, but modified by diagenetic processes as well (Vega et al, 2005). In previous studies (e.g., Dennell, 1960;Hegdahl et al, 1977a, b;Roer & Dillaman, 1984), cuticle structure of Recent taxa has been studied, while other authors have demonstrated the presence of cuticle in the fossil record (e.g., Neville & Berg, 1971;Feldmann & Tshudy, 1987;Vega et al, 1994Vega et al, , 2005Feldmann & Gaździcki, 1998;Guinot & Breton;González-León et al, 2016, 2018. Studies of the functional morphology and taphonomic implications have been addressed by various authors (Schäfer, 1951;Guinot, 1979;Plotnick et al, 1988;Savazzi, 1988;Haj & Feldmann, 2002;Waugh et al, 2004).…”

“…Decapod crustaceans rank amongst the most common animals inhabiting a number of different environments, both at the present day (Abele, 1974) and in the past (Klompmaker et al, 2013;Schweitzer & Feldmann, 2014). The calcified cuticle of decapod crustaceans comprises the hard exoskeleton of the animal and is composed of three layers (Haj & Feldmann, 2002); these layers have been documented in some fossil decapod crustaceans as well (Neville & Berg, 1971;Taylor, 1973;Dalingwater, 1977;Vega et al, 1994Vega et al, , 1998Feldmann & Gaździcki, 1998;Haj & Feldmann, 2002;Waugh & Feldmann, 2003;Vega et al, 2005;Waugh et al, 2006;Amato et al, 2008;Waugh et al, 2009;González-León et al, 2016, 2018. The decapod cuticle has a very distinctive structure when observed in cross section.…”

The cuticle structure of fossil decapod crustaceans is an important tool, not only for palaeocological and taphonomic interpretations, but also as a potential way to characterise systematically genera and even species the cuticle of which has not been severely altered by diagenetic processes. Localities with abundant decapod crustacean remains can be interpreted either as reflecting mass mortality events or just simple accumulations of exuviae, on the basis of completeness and comparison of cuticle structures between specimens of the same species from different localities. Association with anoxic events by microfacies analyses can offer clues to explain the unusual abundance of decapod crustacean remains. This is the case for the Early Cretaceous lobster Atherfieldastacus magnus (M'Coy, 1849), which is found in large numbers in different Lower Cretaceous (mainly Aptian) lithostratigraphic units across the globe. In this case, we document the well-preserved cuticle structure of specimens from the upper Aptian of Chihuahua (Mexico), preserved three-dimensionally, mainly in concretions, which were studied in different transverse sections showing the cuticle in diverse portions of the lobster body. Thin cuticle layers show the typical crustacean cuticular structure that suggest these are corpses preserved in an anoxic environment.

“…After the paper by Guzmán et al (2016) was published, an error related to the catalog numbers of the fossils specimens was pointed out. The codes UN-DG-CR-021 and UN-DG-CR-022 had already been used in the description of Colombian specimens of the lobster Meyeria magna M'Coy, 1849, in the publications of González-León (2016) and González-León et al (2016), forcing us to replace these numbers. By mutual agreement between the authors, new catalog numbers were assigned by the Paleontological Collection of the Universidad Nacional de Colombia.…”

Three specimens of the lobster â\u80\u9cMeyeria rapaxâ\u80\u9d, which represent the first record of this species in Spain, were collected in the Artoles Formation cropping out in the surroundings of the town of Ares del Maestrat in the Maestrat Basin. Microfacies and paleontological analyses of the sedimentary succession containing the fossil lobsters allow us to infer a near-coastal depositional setting. Numerical ages derived from Sr-isotope analyses combined with previous chronostratigraphic studies of the Artoles Formation suggest an early Barremian age for the stratigraphic interval, which is located around the middle part of the formation, with lobsters studied. The study of the morphological features observed in the record of the â\u80\u9cMeyeria rapaxâ\u80\u9d specimens from Spain supports the ascription of the species to the new genus Atherfieldastacus proposed recently for the Mecochiridae family
