The stone tools may have been made by Australopithecus afarensis, the species whose best fossil example is Lucy, which inhabited East Africa at the same time as the date of the oldest stone tools, a yet unidentified species, or by Kenyanthropus platyops (a 3.2 to 3.5-million-year-old Pliocene hominin fossil discovered in 1999).
The toolkit consists of choppers, side, end, and two-edged forms. The splintered ends of the stone tools indicate utilization. Also, two large symmetrical discoid/core tools with bifacially worked edges and a biconvex cross section have been found.
The Swartkrans site is a cave filled with layered fossil-bearing limestone deposits. Oldowan is found in Member 1 Lower Bank at 2.2-1.8 Ma in association with Paranthropus robustus and a single fossil attributed to Homo. The Member I assemblage also includes a shaft of pointed bone polished at the pointed end.
The good preservation of soft tissue, which is very poorly preserved in fossil form, should be emphasized. Despite the good preservation conditions, a large proportion of the fossils are not autochthonous, but were transported during fossilization, caused by the flow of water. This applies mainly to the finds from the mortuary fields and the ...
Fossil collecting (sometimes, in a non-scientific sense, fossil hunting) is the collection of the fossils for scientific study, hobby, or profit. Fossil collecting, as practiced by amateurs, is the predecessor of modern paleontology and many still collect fossils and study fossils as amateurs. Professionals and amateurs alike collect fossils ...
Scientists have found the U.K.’s largest dinosaur footprint site ever. The tracks were discovered in a quarry in Oxfordshire — about 60 miles northwest of London — by quarry employee Gary ...
What clearly distinguishes this industry is the smallness of the toolkit, especially the crescent-shaped backed blades of which one finds thousands of examples. True geometric pieces (in the shape of trapeziums) are excessively rare, barely three parts per thousand, whereas in the ancient Neolithic with pottery and polished stone, small pieces ...
This fossil was a puzzle, as its head looked rather like that of an arthropod but its body, with what seemed to be fins along its back and belly, looked rather like of a chordate's. [58] In 2010 Smith and Caron described another 91 specimens, some very good, and reconstructed it as a cephalopod, and the earliest one as of 2010. Unlike later ...
