Coyoacán, 04510, México D. F., Mexico. * [email protected] ABSTRACT The presence of the genera Costacopluma and Ophthalmoplax in Upper Cretaceous (Campanian) Moroccan strata is documented on the basis of specimens collected from the Calcaires à slumps de Taghit Formation, Moyenne Moulouya (Morocco). Two new species are described, Ophthalmoplax minimus and Costacopluma maroccana. The first record for Opthalmoplax in the west Tethyan realm is reported, and systematic affinities of this genus and its species are discussed. An absolute age of the late Campanian was obtained for this assemblage from 87Sr/86Sr analysis applied to well preserved cuticle calcitic remains of Ophthalmoplax minimus. Costacopluma maroccana represents the 14th species for this genus and the fourth Cretaceous species. Its morphology reinforces hypothesis of two main phyletic groups for this genus. Key words: Crustacea, Decapoda, Ophthalmoplax, Costacopluma, Campanian, Morocco. RESUMEN Se documenta la presencia de los géneros Ophthalmoplax y Costacopluma con base en especímenes recolectados en sedimentos del Cretácico Superior (Campaniano) de la Moyenne Mouluya (Marruecos). Se describen dos nuevas especies: Ophthalmoplax minimus y Costacopluma maroccana. Se identifíca y localiza (por primera vez en la parte occidental del dominio del Tethys) el género Ophthalmoplax, discutiéndose las afinidades sistemáticas de este género y sus especies.

Bulk sampling and extensive, systematic surface collecting of the Coon Creek Member of the Ripley Formation (early Maastrichtian) at the Blue Springs locality and primarily bulk sampling of the Owl Creek Formation (late Maastrichtian) at the Owl Creek type locality, both in northeast Mississippi, USA, have produced the largest and most highly diversified actinopterygian otolith (ear stone) assemblage described from the Mesozoic of North America. The 3,802 otoliths represent 30 taxa of bony fishes representing at least 22 families. In addition, there were two different morphological types of lapilli, which were not identifiable to species level.

Mark Twain • Keywords: Brachyura, phylogeny, foregut-ossicles, fossil record • Schlagworte: Brachyura, Phylogenie, Magenossikel, Fossilbericht Abstract Within the Decapoda the taxon Brachyura is the species-richest taxon with up to 10000 species. The phylogeny of the Brachyura has been discussed based on morphological and molecular investigations since more than a century. The investigation of the foregut-ossicles and gastric-teeth of 66 brachyuran species, is a new approach to answer important phylogenetic questions. Using a specific staining pigment Alizarin Red S, six new described foregut-ossicles are added to an existing nomenclature. As a result of this method the presence of 41 foregut-ossicles is proposed for the ground pattern of the Brachyura. The cladistic analysis supports a monophyletic origin of the Brachyura including the Dromiidae and the Raninidae. The taxa Podotremata and Heterotremata, postulated as monophyletic by Guinot (1977, 1978), are not supported in the present study. The Dromiidae and Raninidae, which are placed within the Podotremata sensu Guinot, are closer related to the “higher crabs”.

    Big Oyster, Robust Echinoid: an Unusual Association from the Maastrichtian Type Area (Province of Limburg, Southern Netherlands)

    Swiss Journal of Palaeontology (2018) 137:357–361 https://doi.org/10.1007/s13358-018-0151-3 (0123456789().,-volV)(0123456789().,-volV) REGULAR RESEARCH ARTICLE Big oyster, robust echinoid: an unusual association from the Maastrichtian type area (province of Limburg, southern Netherlands) 1,2 3 Stephen K. Donovan • John W. M. Jagt Received: 27 February 2018 / Accepted: 10 May 2018 / Published online: 1 June 2018 Ó Akademie der Naturwissenschaften Schweiz (SCNAT) 2018 Abstract Large, denuded tests of holasteroid echinoids were robust benthic islands in the Late Cretaceous seas of northwest Europe. A test of Hemipneustes striatoradiatus (Leske) from the Nekum Member (Maastricht Formation; upper Maastrichtian) of southern Limburg, the Netherlands, is encrusted by a large oyster, Pycnodonte (Phygraea) vesiculare (Lamarck). This specimen is a palaeoecological conundrum, at least in part. No other members of the same oyster spatfall attached to this test and survived. Indeed, only two other, much smaller bivalve shells, assignable to the same species, attached either then or somewhat later. The oyster, although large, could have grown to this size in a single season. The larval oyster cemented high on the test and this would have been advantageous initially, the young shell being elevated above sediment-laden bottom waters. However, as the oyster grew, the incurrent margin of the commissure would have grown closer to the sediment surface. Thus, the quality of the incurrent water probably deteriorated with time.

Fernández Recibido: 7 de julio de 2020 Aceptado: 14 de septiembre de 2020 ABSTRACT A total of 22 concretions containing 37 decapod crustacean specimens belonging to the family Axiidae, from the Hauterivian (Lower Cretaceous) of the Agrio Formation in the Neuquén Basin, were studied. The decapods were assigned to Protaxius sp., which likely had a fossorial life habit. In this work we attempt to determine, through taphonomic analysis, if the specimens fossilized within their burrows or outside them in order to interpret paleobiological aspects of the studied taxon. Several taphonomic criteria of the specimens and concretions, known from the literature, were applied and their utility discussed, including anatomical disposition, completeness of specimens, orientation and alignment, dispersion of exoskeletal elements in the concretion, preservation of both chelae, sedimentary fabric of the concretion, position within the concretion, and shape of the concretions. The relative importance of these criteria was discussed especially in those concretions with conflicting evidence pointing to either fossilization within or outside burrow systems.

The fossils occur in succes- sions of the informal earliest late Campanian Belemnellocamax balsvikensis zone at A˚ sen and the latest early Campanian B. mammillatus zone at Ivo¨ Klack, both in the Kristianstad Basin of NE Ska˚ne. Numerous, heavily calcified chelipeds were found within a restricted bed at A˚ sen that was rich in carbonate-cemented nodules. Based on the burrowing lifestyle of modern mud shrimps, we interpret these nodules as infilled burrow chambers. The low abundance of molluscs within the Protocallianassa beds is also consistent with analogous extant communities, indicating that a similar ecologically exclusive relationship ruled within the Late Cretaceous shallow- marine ecosystems.
