“…Subsequently, Klompmaker et al (2011) included Rathbunopon in Prosopidae again based on its close similarity to what is now known as Europrosopon, a fit with the diagnosis of Prosopidae in Schweitzer and Feldmann (2009d), and the presence of an augenrest in Rathbunopon, a feature that would be characteristic of prosopids (but see some species of Laeviprosopon). Subsequent papers by Guinot (2019) and Collins et al (2020) kept Rathbunopon in Glaessneropsidae, but others favored placement in Prosopidae (González-León et al, 2016;Ossó et al, 2018). Schweitzer et al (2012bSchweitzer et al ( , 2018 maintained placement in Glaessneropsidae and provided a more detailed explanation providing only differences in orbital characters.…”

The Late Jurassic marks the first major radiation among true crabs (Brachyura) in reef environments, followed by another diversification in the mid-to Late Cretaceous in multiple habitats. We studied brachyuran carapaces from Mesozoic sponge-and coralassociated limestones in Europe. Six new taxa are described: Late Jurassic Europrosopon gen. nov., Eodromites bernchrisdomiorum sp. nov., Prosopon josephcollinsi sp. nov., Tanidromites nightwishorum sp. nov., and T. weinschenki sp. nov.; and mid-Cretaceous Eodromites cristinarobinsae sp. nov. Furthermore, we recognize four junior synonyms: Eodromites grandis (=E. guenteri), Tanidromites scheffnerae (=T. wysokaensis), and Europrosopon aculeatum (=E. verrucosum and E. barbulescuae). Five taxa are reassigned: Eodromites aequilatus to Tanidromites, Tanidromites rotundus to Eodromites, Nodoprosopon dzhafarberdensis to ?Abyssophthalmus, Nodoprosopon from Nodoprosopidae to Homolodromiidae, and Rathbunopon from Glaessneropsidae to Prosopidae. Several other taxa are redescribed. The latter reassignment indicates that Rathbunopon does not represent an example of extreme convergent evolution as implied previously. Conversely, the frontal structure consisting of a rostrum with two diverging spines and outer orbital spines appears a remarkable example of convergent evolution of the goniodromitid Navarradromites toward members of Homolodromiidae, for which this frontal structure is characteristic. Rostral spines represent another example of convergent evolution. Some specimens are extraordinary: A specimen of Abyssophthalmus cf. A. spinosus represents the largest complete reported Jurassic brachyuran thus far and one specimen of Planoprosopon aff. P. hystricosus bears one of the largest known parasitic isopod-induced swellings (ichnotaxon Kanthyloma crusta) relative to carapace size. Overall, our results indicate that biodiversity and convergent evolution in Mesozoic brachyurans remain understudied.

“…I do not agree with the family status of the Goniodromitidae and placement in the superfamily Homolodromioidea, as subscribed to by most authors (Van Straelen 1925;Schweitzer et al 2007Schweitzer et al , 2009Schweitzer et al , 2012aSchweitzer et al , 2018aSchweitzer & Feldmann 2008a;De Grave et al 2009;Karasawa et al 2011;Franţescu 2011;Klompmaker et al 2012;Feldmann et al 2013;Starzyk et al 2012Starzyk et al , 2015bHyžný et al 2015). Instead, I favour assignment to the Dromioidea (similarly to Wright & Wright 1950), probably within the Dromiidae, and at a subfamily rank, Goniodromitinae (which takes priority over the Pithonotinae Glaessner, 1933;see Wehner 1988), as proposed previously by Ossó et al (2018). The Goniodromitinae, which in its current composition comprises numerous and highly diverse genera (see Jagt et al 2015), with a large number of species placed either in Goniodromites or Pithonoton (see Feldmann et al 2006;Schweitzer & Feldmann 2008a: tables 1, 2), appears paraphyletic (see Ossó et al 2018: 102, figs 9, 10), which means that all genera and species must be re-examined, with a re-evaluation of their taxonomic placement.…”

All Jurassic brachyuran taxa known to date are based solely upon dorsal carapaces, and only a limited number of Early and mid-Cretaceous crabs retain ventral parts. Therefore, all Jurassic taxa and many forms from the first half of the Cretaceous are carapace-based entities. All of them are considered to be "dromiaceans", podotremes to be precise. The recent discovery of an exceptionally well-preserved male crab from the Upper Cretaceous (lower Cenomanian) of Chiapas (Mexico), Archaeochiapasa mardoqueoi Guinot, Carbot-Chanona & Vega, 2019, at first sight of a podotreme nature, has allowed a detailed description of its thoracic sternum and pleon, which revealed that it was actually a typical eubrachyuran, in need of a new family, Archaeochiapasidae Guinot, Carbot-Chanona & Vega, 2019. This has brought back to life one of my earlier ideas about the possible non-podotreme nature of certain enigmatic Late Jurassic and Cretaceous Brachyura previously placed in various "dromiacean" (i.e., podotreme) families and superfamilies. My investigations have led the me to formulate the present hypothesis that the extinct families Bucculentidae Schweitzer & Feldmann, 2009 (currently assigned to the Homolodromioidea Al-

Geology of the ‘Sénia stone’ from Ulldecona, Catalonia (Aptian, Maestrat Basin, Iberian Chain) and its implications for regional stratigraphy

The municipality of the town of Ulldecona (Catalonia) is notable for extensive quarrying activities, which exploit limestone, popularly named Stone from Ulldecona, for ornamental and building purposes. The Stone from Ulldecona, commercially known as Sénia stone, is one of the most important ornamental and building stones quarried in Catalonia, and is used worldwide in all kinds of public and private buildings. Little is known about the geological nature of this stratigraphic interval of commercial value. Therefore, this study explores the geology of the Stone from Ulldecona in open pit quarries and natural outcrops. The Stone from Ulldecona consists of limestones of upper lower Aptian age, including wackestone, packstone and grainstone textures containing peloids, miliolids, Palorbitolina lenticularis, Orbitolinopsis simplex, Paracoskinolina maynci, Lithocodium aggregatum, Choffatella decipiens, Salpingoporella muehlbergi, Chondrodonta, Toucasia carinata, Polyconites sp. and Mathesia darderi. These platform carbonates rich in orbitolinids and rudists belong to the Villarroya de los Pinares Formation of the Maestrat Basin. Locally, the limestones are highly bioturbated and/or dolomitized. Dolomitic limestones, calcitic dolostones and dolostones are stratabound tabular geobodies with thicknesses of up to 60 metres. Dolomitic limestones and calcitic dolostones corresponding to initial and intermediate stages of dolomitization mainly exhibit isolated euhedral dolomite crystals or idiotopic mosaics. Dolostones (advanced dolomitization stages) are sucrose, exhibit vacuolar and cave porosities, and are characterized by idiotopic and hypidiotopic mosaics, which indicate temperatures lower than 50-60ºC during dolomitization. Dolomite textures are mainly fabric-destructive and pervasive, but locally retentive and/or selective fabrics also occur. The limestones of the Villarroya de los Pinares Formation, the underlying marls of the Forcall Formation and the overlying marls and platform carbonates of the Benassal Formation examined can be arranged into two high-rank, low-frequency transgressive-regressive sequences. Similar coeval long-term transgressive-regressive trends have been reported from other 2 basins, indicating that eustatism largely controlled accommodation of the Aptian succession studied in Ulldecona.
