Article Reference A classic Late Frasnian chondrychtyan assemblage from southern Belgium

Article Reference A classic Late Frasnian chondrichthyan assemblage from southern Belgium
Samples from the Upper Frasnian (Devonian) of Lompret Quarry and Nismes railway section in Dinant Synclinorium, southern Belgium, yielded several chondrichthyan teeth and scales. The teeth belong to three genera: Phoebodus, Cladodoides and Protacrodus. The comparison with selected Late Frasnian chondrichthyan assemblages from the seas between Laurussia and Gondwana revealed substantial local differences of taxonomic composition due to palaeoenvironmental conditions, such as depth, distance to submarine platforms, oxygenation of water, and possibly also temperature. The assemblage from Belgium, with its high frequency of phoebodonts, is the most similar to that from the Ryauzyak section, South Urals, Russia, and the Horse Spring section, Canning Basin, Australia.

Article Reference A diverse bird assemblage from the Ypresian of Belgium furthers knowledge of Early Eocene avifaunas of the North Sea Basin
We describe an assemblage of 54 avian bones from early Eocene marine sediments of the Ampe quarry near Egem in Belgium. The fossils belong to at least 20 species in more than 11 higher-level taxa. Well-identifiable specimens are assigned to the Odontopterygiformes, Galliformes, Messelornithidae, Apodiformes, Halcyornithidae, Leptosomiformes (cf.Plesiocathartes), and Coraciiformes (cf. Septencoracias). Further specimens are tentatively referred to the phaethontiform Prophaethontidae and to the Accipitridae, Masillaraptoridae, and Alcediniformes. The threedimensionally preserved fossils from Egem provide new data on the osteology of taxa that are otherwise mainly known from compression fossils with crushed bones. The material also includes specimens that further knowledge of the composition of early Eocene avifaunas of the North Sea Basin. The comparatively well-represented small galliform species is clearly distinguished from the early Eocene Gallinuloididae and most closely resembles Argillipes aurorum, a largely ignored galliform species from the London Clay. The tentatively identified fossils of Accipitridae and Alcediniformes would represent the earliest fossil records of these clades. The bird assemblage from Egem includes relatively few seabirds (Odontopterygiformes, cf. Prophaethontidae) and is dominated by remains of terrestrial species (Galliformes, Messelornithidae). Arboreal birds (Halcyornithidae, Leptosomiformes, cf. Alcediniformes, Coraciiformes) are less abundant and aerial insectivores (Apodiformes) very scarce, which either indicates a taphonomic bias in the composition of the avifauna or particular paleoenvironmental characteristics of the nearshore habitats in that area of the southern North Sea Basin.

Article Reference A fossil albatross from the early Oligocene of the North Sea Basin
We describe a stem group representative of Diomedeidae from the early Oligocene (Rupelian) of Belgium. The fossil remains, wing, and pectoral girdle bones of two individuals are described as Tydea septentrionalis, gen. et sp. nov., and constitute the earliest well-established record of the taxon and the first Paleogene record from the North Sea Basin. The new species was about the size of the extant Black-browed Albatross (Thalassarche melanophris) and establishes that albatrosses had already reached a large size 30 mya. The wing bones of T. septentrionalis are distinguished by several plesiomorphic features from those of species in crown group Diomedeidae, which may indicate differences in aerodynamic performance between the fossil species and extant albatrosses. We detail that a previously described early Miocene species, “Plotornis” arvernensis, should be expunged from the fossil record of albatrosses. However, the new fossils provide further evidence that the extant, mainly Southern Hemispheric, distribution of albatrosses is relictual compared with the past distribution of the total group (stem group + crown group). With unambiguous records from the early Oligocene, early Miocene, and Pliocene, albatrosses are now known to have had a long evolutionary history in the European part of the North Atlantic, but the reasons for their extinction remain poorly understood
