John’s, Newfoundland and Labrador, Canada,. Philips, Newfoundland and Labrador, Canada,. Performed the experiments: SB. Analyzed the data: SB AM. Anthoptilum grandiflorum and Halipteris finmarchica are two deep-sea corals Octocorallia: Pennatulacea common on soft bottoms in the North Atlantic where they are believed to act as biogenic habitat. The former also has a worldwide distribution. To assist conservation efforts, this study examines spatial and temporal patterns in the abundance, diversity, and nature of their faunal associates. A total of 14 species were found on A. Among those, 7 and 5 species, respectively, were attached to the sea pens and categorized as close associates or symbionts. Rarefaction analyses suggest that the most common associates of both sea pens have been sampled.

Objects are said to be in association with each other when they are found together in a context which suggests simultaneous deposition. Associations between objects are the basis for relative dating or chronology and the concept of cross-dating as well as in interpretation – cultural connections, original function, etc.

cal review of the validity of the associations of Stegodon and Elephas during the Early absolute chronometric dating of faunal assemblages includ-.

This paper focuses on the Early Pleistocene of China and Southeast Asia, where the Ailuropoda-Stegodon complex is considered to be a chronologically significant faunal association in the following period. However, the stratigraphic contexts of these local faunal complexes require clarification. Indeed, after one century of research to establish a regional biostratigraphy and in spite of the recomandations provided in the s, many geochronological surveys were undertaken in the s but many problems still exist.

Thus, as a first step, taking into consideration the uncertain nature of the geological, taphonomic and chronological data, this paper proposes a critical review of the validity of the associations of Stegodon and Elephas during the Early Pleistocene for this geographical area. Finally, it was necessary to expose what are the current problems before to try to solve them rather than to pursue an unfounded headlong rush.

This review concludes that very few reliable data are available and that high-level resolution MIS palaeoecological modelization is almost impossible, severely hindering any discussions of strict interaction between humans and proboscideans.

New dating evidence of the early presence of hominins in Southern Europe

Description: This perennial fern consists of a few loose leaves that develop directly from the rootstock. Infertile leaves are more common than fertile leaves. The infertile leaves are yellowish green to medium green, hairless, and ovate in outline; they are deeply pinnatifid for the most part, although their tips are more shallowly pinnatifid, while their bases are more pinnate.

sample that we can compile of sites with faunal remains that date, at least potentially, to the Early Paleoindian period and for which human associations have.

These are a mottled silty mudstone facies facies A , a laminated shale facies facies B , and a laminated siltstone facies facies C. Facies A consists of variably bioturbated silty mudstones, muddy siltstones, and fissile shales. It developed in relatively shallow water conditions; mudstones were presumably deposited from suspension, and siltstone laminae and thin layers were formed by increased wave and current activity.

Mottling resulted from bioturbation by epifaunal and, particularly, infaunal benthic organisms. Within facies A, two subfacies are recognized: A i is mudstone dominated, and A ii is fine-grained siltstone dominated. Facies B consists of alternating laminae of undisturbed mudstone and fine-grained siltstone probably produced as a result of deposition from suspension during a temporary upward expansion of the oxygen-minimum layer.

Facies C consists of 0.

Initially work has been centred on creating and refining the way in which faunal remains are recorded on site to build up a database that will be usable away from the physical remains themselves. Differential preservation across the city means that the same method is not applicable in all areas. In some areas preservation has been excellent facilitating the recording of measurements and the use of statistical tools such as the Minimum Number of Individuals MNI ; in other areas bone is very fragmentary or burned and so weight is the more appropriate measure.

Work on site has been divided into several smaller projects all essentially sharing the same methodology. All projects begin with cleaning and numbering the bones and entering data into the catalogue. Butchery marks and possible causes of death are observed where appropriate.

Correlation is, as mentioned earlier, the technique of piecing together the informational content of separated outcrops. When information derived from two outcrops is integrated , the time interval they represent is probably greater than that of each alone. This optimistic hope, however, must be tempered by the realization that much of the Precambrian record—older than million years—is missing.

Correlating two separated outcrops means establishing that they share certain characteristics indicative of contemporary formation. The most useful indication of time equivalence is similar fossil content, provided of course that such remains are present. The basis for assuming that like fossils indicate contemporary formation is faunal succession. However, as previously noted, times of volcanism and metamorphism, which are both critical parts of global processes, cannot be correlated by fossil content.

Furthermore, useful fossils are either rare or totally absent in rocks from Precambrian time, which constitutes more than 87 percent of Earth history. Precambrian rocks must therefore be correlated by means of precise isotopic dating. Unlike the principles of superposition and crosscutting, faunal succession is a secondary principle.

That is to say, it depends on other sequence-determining principles for establishing its validity. Suppose there exist a number of fossil-bearing outcrops each composed of sedimentary layers that can be arranged in relative order, primarily based on superposition.

These dates therefore imply that the Pleistocene human occupation of the site consists of a relatively late Early Upper Paleolithic or very early Middle Upper Paleolithic and a fairly late Middle Paleolithic. Stable isotope analysis of the dated samples reinforces the ecological flexibility of Late Pleistocene cave bears. The remainder of the contents of the complex cave system, however, remains poorly dated. This situation is especially evident in the existing collections,.
