By Terry Harrison (auth.), Terry Harrison (eds.)

This quantity 1 and its better half quantity 2 current the result of new investigations into the geology, paleontology and paleoecology of the early hominin website of Laetoli in northern Tanzania. the location is without doubt one of the most vital paleontological and paleoanthropological websites in Africa, worldrenowned for the invention of fossils of the early hominin Australopithecus afarensis, in addition to impressive trails of its footprints. the 1st quantity offers new proof at the geology, geochronology, ecology, ecomorphology and taphonomy of the positioning. the second one quantity describes newly chanced on fossil hominins from Laetoli, belonging to Australopithecus afarensis and Paranthropus aethiopicus, and provides distinct details at the systematics and paleobiology of the various linked fauna. jointly, those contributions supply probably the most complete money owed of a fossil hominin website, they usually supply very important new insights into the early levels of human evolution and its context.

Biodiversity Response to Climate Change in the Middle Pleistocene: The Porcupine Cave Fauna from Colorado

This e-book chronicles the invention and research of animal fossils present in probably the most vital paleontological websites within the world-Porcupine Cave, situated at an elevation of 9,500 toes within the Colorado Rocky Mountains. With tens of millions of pointed out specimens, this website has develop into the major resource of data at the fauna of North America's better elevations among nearly 1 million and 600,000 years in the past, a interval that observed the improvement and retreat of glaciers a number of instances.

Fossil Reptiles of Great Britain

British Fossil reptile websites are of foreign value because they contain continues to be that fill the time gaps poorly identified in other places. They comprise wealthy vintage reptile beds that have been the resource of dozens of significant specimens. This quantity information all these websites that experience yielded fossil reptiles.

The Great American Biotic Interchange: A South American Perspective

South American ecosystems suffered one of many maximum biogeographical occasions, after the institution of the Panamian land bridge, known as the “Great American Biotic Interchange” (GABI). This refers back to the alternate, in different levels, of land mammals among the Americas; this occasion all started throughout the past due Miocene with the looks of the Holartic Procyonidae (Huayquerian Age) in South the United States and keeps at the present time.

Example text

A number of small, vertically standing boles penetrate Tuff 7, and these presumably represent the remains of trees that were partially buried by the ash fall. At the eastern end of the locality, a number of leaf impressions are preserved in a coarse-grained dark grey tuff at the top of Tuff 8 (Bamford 2011a). 30 Locality 16. Fossil seeds, twigs and wood exposed on the basal layer of Tuff 7 in the eastern arm of Loc. 16 about 6 m thick. This is overlain by the Olpiro Beds, which contain large mammal fossils and stone tools (although Leakey [1987a] suggests that most of these may originally have been derived from the Ngaloba Beds) (Fig.

There is little topographic relief and the main gully cuts through thick deposits of mbuga clay, Ngaloba Beds, and the upper part of the Upper Laetolil Beds, especially the Yellow Marker Tuff. Few fossils were recovered from the river gully itself. 38). 38 Locality 23. Exposures of Lower Ngaloba Beds on the northern flank of a tributary of the Gadjingero River 2 Paleontological Localities 37 Silal Artum Fig. 39). Harris and Harris (1981) presented a preliminary account of archaeological excavations conducted in September 1979.

7 km wide, which abuts against the north slope of Norsigidok Hill. 23). 24). The section of Upper Laetolil Beds exposed, excluding the Yellow marker Tuff, is about 13–15 m thick. Fossil vertebrates have been recovered from between Tuffs 7 and 8, but these are less common than those between Tuffs 5 and 7. Loc. 10E is the most productive of the localities at Laetoli, with well over 2,500 fossil mammals recovered. H. 24) discovered in 1978 (Leakey 1987b). The Footprint Tuff is well exposed at the locality, and several Footprint sites (F, H, I, J) have been designated (Leakey 1987c).
