Two new species of spiny barnacles (Balanoidea: Acastinae, Balaninae) are described from the lower Burdigalian (Early Miocene) of the Aquitaine Basin, southwest France. The first, Acasta martillacensis sp. nov., from Martillac, is characterised by a shell with internal longitudinal ribs, a cellular space between the sheath and wall, a carinal sheath which adheres to the wall in the centre of its basal edge, a cup-shaped basis and a scutum with radial striae externally and a less than prominent adductor ridge internally. The second, Balanus aculeatus sp. nov., from Saucats (Le Péloua), has paries exteriorly with strong, tubular spines. An overview of outcrops of Burdigalian strata in the area, within a palaeogeographic context, is added.

Two New Species

The early Miocene site of Wadi Moghra, Qattara Depression, Egypt, is important for interpreting anthracothere (Mammalia, Artiodactyla) evolution, because the Moghra sediments preserve a higher diversity of anthracotheres than any other pene-contemporaneous site. New specimens from Moghra are described and form the basis for the systematic revision of Moghra anthracotheres provided here. Among the important discoveries recently made at Moghra is the first complete skull of Sivameryx moneyi. Other new specimens described here include two new species of Afromeryx, and a new genus and species, all of which are unique to Moghra. A review of biogeographic information supports the conclusion that three of the Moghra anthracotheres (Brachyodus depereti, B. mogharensis, and Jaggermeryx naida, n. gen. n. sp.) are members of late surviving lineages with a long history in Africa, while three other species (Afromeryx grex, n. sp., A. palustris, n. sp., and Sivameryx moneyi) represent more recent immigrants from Eurasia.

Two New Species

A new Tertiary gastropod genus, Peonza n. gen., is described, along with two new species, P. torquata from southern Argentina and P. benjamina from southern Chile. These muricacean gastropods, of uncertain familial status, occur in the late Eocene San Julián Formation and in the late Oligocene to early Miocene? Monte León Formation, Santa Cruz Province, Argentina. They also were recorded in the (probably) Oligocene Magellanian beds in Tierra del Fuego, Argentina, and in early Miocene deposits of the Tres Montes region in the Chilean Canals. In spite of the small number of specimens, Peonza n. gen. seems to have had a wide geographic and temporal distribution.

A late Burdigalian bathyal mollusc fauna from the Vienna Basin (Slovakia)This is the first record of a bathyal mollusc fauna from the late Early Miocene of the Central Paratethys. The assemblage shows clear affinities to coeval faunas of the Turin Hills in the Mediterranean area and the Aquitaine Basin in France. The overall biostratigraphic value of the assemblage is hard to estimate due to the general very poor knowledge of Miocene bathyal faunas. Several species, however, are known from deep water deposits of the Middle Miocene Badenian stage as well. This implies Early Miocene roots of parts of the Middle Miocene deep water fauna and suggests a low turnover for bathyal mollusc communities at the Early-Middle Miocene boundary. The nassariid gastropodNassarius janschloegliHarzhauser nov. sp. and the naticid gastropodPolinices cerovaensisHarzhauser nov. sp. are introduced as new species.

Fossil Genus

At least seven foliar taxa of Proteaceae occur in Oligo–Miocene lignite from the Newvale site. These taxa include two new species of the fossil genus Euproteaciphyllum, and previously described species of tribe Persoonieae and Banksia. Other specimens from Newvale are not assigned to new species, but some conform to leaves of the New Caledonian genus Beauprea, which is also represented in the lignite by common pollen. Two other Euproteaciphyllum species are described from the early Miocene Foulden Maar diatomite site. One of these species may belong to Alloxylon (tribe Embothrieae) and the other to tribe Macadamieae, subtribe Gevuininae. Ecologically, the species from Newvale represented important components of wet, oligotrophic, open vegetation containing scleromorphic angiosperms and very diverse conifers. In contrast, Proteaceae were large-leaved and rare in Lauraceae-dominated rainforest at the volcanic Foulden Maar site. Overall, the Oligo–Miocene fossils confirm that Proteaceae was formerly much more diverse and dominant in the New Zealand vegetation, and provide fossil evidence for biome conservatism in both leaf traits and lineage representation.

Two New Species

A tubiferous cirripede Tetraclitella judiciae sp. nov., previously known only from two isolated and incomplete shell wall plates identified as Tetraclitella sp. cf. T. purpurascens (Wood, 1815), is described from the early Miocene of Victoria, Australia; a further taxon, Tetraclitella purpurascens miocenica subsp. nov., occurs in the late Miocene-Pliocene of Victoria, and specimens from the early Miocene of New Zealand, previously recorded as Tetraclitella sp. cf. T. purpurascens (Wood, 1815) are redesignated as Tetraclitella nodicostata sp. nov. Tetraclitella is the first cirripede genus known to have had tubiferous walls. Incorporation of chitinous stringers within the shell wall of early tetraclitids (e.g. Epopella) may have facilitated the development of the tubiferous shell wall, which permitted sessile barnacles to maximise the shell strength to calcite ratio: in doing so, these chitinous stringers not only reduced the diversion of energy required to extract calcium carbonate from seawater, but improved the effectiveness of the shell wall in resisting predators. It is also argued here that the presence of chitin within the shell increased resistance to both corrasion and corrosion, the latter becoming an increasing problem for calcareous shelled organisms following a drop in the pH of seawater after the PalaeoceneEocene Thermal Maximum.

Abstract. Two new species of dinocyst, Cerbia monilis and Hapsocysta susanae are described from the Lower Cretaceous of the Central North Sea Basin. The first ranges across the Aptian/Albian boundary and the latter is restricted to the Early to Middle Albian interval; both are valuable index taxa in this area. Hapsocysta susanae is remarkably similar to cysts ‘without walls’ described from the Late Oligocene and Early Miocene, and detailed comparisons are made. The ranges of the two species described here are illustrated against regional lithostratigraphic and biostratigraphic schemes.

AbstractWe describe two new species of Symplocos (Symplocaceae) from the early Miocene Brandon Lignite Flora of Vermont, USA. The endocarps of Symplocos laevigata (Lesq.) comb. nov. are most similar in morphology and anatomy to those of the extant species S. tinctoria of southeastern North America and S. wikstroemiifolia of eastern Asia, both of S. sect. Hopea, and to those of several species of S. sect. Lodhra, endemic to eastern Asia; they are also somewhat similar to those of S. minutula of the Tertiary of Europe. The endocarps of Symplocos hitchcockii sp. nov. are most similar in morphology and anatomy to those of living members of S. sect. Lodhra, and are also somewhat similar to fossil S. incurva of the Tertiary of Europe. This report extends the fossil record of Symplocos endocarps to eastern North America and underscores the mixed mesophytic to subtropical nature of the Brandon flora.

Of Greece

Two specimens of fossil lauraceous woods from the Cainozoic (early Miocene) of Greece (southern part of Lesbos Island and central-eastern part of Lemnos Island) were studied. Their microscopic characteristics revealed two different kinds of fossil lauraceous woods with a different distribution of idioblasts (oil and/or mucilage cells) which do not correspond to the pattern in Laurinoxylon. The determination as two new species of Cryptocaryoxylon (C. lesbium sp. nov., C. lemnium sp. nov.) is proposed. A discussion of described Cryptocaryoxylon species, which have a worldwide distribution, is also presented. The assignment of the two Greek specimens to the genus Cryptocaryoxylon and their nomination as the first occurrences of this genus from the Neogene of Eurasia is supported.
