Burin (lithic flake) in the context of Chisel

The Baradostian culture was an Upper Paleolithic flint industry culture found in the Zagros region in the border-country between Iraq and Iran. It was preceded by the Middle Paleolithic Mousterian culture, directly overlying it without an intervening bladelet industry.

According to M. Otte, the Baradostian culture is part of the Aurignacian traditions. This culture is known for the high percentage of burins and some of these are similar to the distinctive nosed profile of the Aurignacian burins.

The Levantine Aurignacian (35,000-29,000 BP, calibrated, 32,000-26,000 BP, non-calibrated) is an Upper Paleolithic culture of the Near-Eastern Levant that evolved from the Emiran culture. It was named so because of the similarity of stone tools with the Aurignacian culture in Europe. The Levantine Aurignacian used to be called Lower and Upper Antelian in old sources, from the site of Wadi Antelias in Lebanon. The most important innovation in this period is the incorporation of some typical elements of Aurignacian, like some types of burins and narrow blade points that resemble the European type of Font-Yves.

A microburin is a characteristic waste product from manufacture of lithic tools — sometimes confused with an authentic burin — which is characteristic of the Mesolithic, but which has been recorded from the end of the Upper Paleolithic until the Chalcolithic. This type of lithic artifact was first named by Henri Breuil who defined it as "a type of angular, smooth, with a terminal retouch in the form of a small notch". Breuil initially thought that the microburins had a functional use as a type of microlithic burin. However, he later came to realize that the manufacturing technique was different from that of the burin and that they could be waste products from the manufacture of microliths, but they may have occasionally been reused for a useful purpose, which is expected for parsimonious lithic resource exploitation

A microburin is a fragment of a lithic flake, or more precisely, of a lithic blade, that shows on its upper face the beginnings of a notch terminating in an oblique flection (whose surface can only be seen from the lower side) that ends in a very acute trihedral apex. It was thought that microburins were exclusively a class of functional microliths, but knapping experiments, along with the refitting of contiguous pieces, have demonstrated that they are a characteristic waste product of an advanced lithic reduction process known as microburin technique - or more correctly, microburin blow technique, following a study of thousands of microburins originating from a variety of Saharan sites. Jacques Tixier noted that none of the examples studied showed unambiguous traces of intentional use, which also validates observation of lack of use wear from analysis of European pieces.Examples found in Europe can be seen on this page : https://web.archive.org/web/20090131231751/http://archeobase.be/page_microburins_meso.html, which are associated with Mesolithic hunters of Wallonia (Belgium) (approximately 9,000 BP).

The Dorset was a Paleo-Eskimo culture, lasting from 500 BCE to between 1000 CE and 1500 CE, that followed the Pre-Dorset and preceded the Thule people (proto-Inuit) in the North American Arctic. The culture and people are named after Cape Dorset (now Kinngait) in Nunavut, Canada, where the first evidence of its existence was found. The culture has been defined as having four phases due to the distinct differences in the technologies relating to hunting and tool making. Artifacts include distinctive triangular end-blades, oil lamps (qulliq) made of soapstone, and burins.

The Dorset were first identified as a separate culture in 1925. The Dorset appear to have been extinct by 1500 at the latest and perhaps as early as 1000. The Thule people, who began migrating east from Alaska in the 11th century, ended up spreading through the lands previously inhabited by the Dorset. It is not fully known whether the Inuit and Dorset ever met. Some modern genetic studies show the Dorset population were distinct from later groups and that "There was virtually no evidence of genetic or cultural interaction between the Dorset and the Thule peoples."
