The ocean's profound inaccessibility makes it impossible to comprehend except through the mediation of technology. The first investigators to explore the great depths were hydrographers whose work was animated by mid‐nineteenth century growth of political, economic, and cultural interest in the oceans. While submarine telegraphy certainly boosted ocean science, interest in this field derived first from commercial concerns related to whaling and shipping as well as the intellectual pursuits of physical geography and questions about the existence of life at great depths. Hydrographers’ developing conception of the oceanic environment never represented a clear translation from technology. Dramatic changes in the understanding of the shape of the deep‐sea floor testified to the complexity of interaction between sounding machines, methods, and interpretations of depth. The shifting image of the sea floor not only reflected increasingly accurate measurements, but also mirrored shifting human motivations for studying this unexplored territory.  相似文献

Benson, R.B.J., Fitzgerald, E.M.G., Rich, T.H. & Vickers-Rich, P., 2013. Large freshwater plesiosaurian from the Cretaceous (Aptian) of Australia. Alcheringa 37, 1–6. ISSN 0311-5518

We report a large plesiosaurian tooth from the freshwater early–middle Aptian (Early Cretaceous) Eumeralla Formation of Victoria, Australia. This, combined with records of smaller plesiosaurian teeth with an alternative morphology, provides evidence for a multitaxic freshwater plesiosaurian assemblage. Dental and body size differences suggest ecological partitioning of sympatric freshwater plesiosaurians analogous to that in modern freshwater odontocete cetaceans. The evolutionarily plastic body plan of Plesiosauria may have facilitated niche differentiation and helped them to exclude ichthyosaurs from freshwater environments during the Mesozoic. However, confirmation of this hypothesis requires the discovery of more complete remains.

Examples of early astogeny in the species Carinatocella harmeri (Stach), Costaticella hastata (Busk) and Claviporella aurita (Busk) are discussed. The primary zoid differs in each species and if found fossil, only in C. hastata could this zoid be recognised as a bryozoan fragment. Analogous development in other Bryozoa is discussed.  相似文献
