	Eraillure
		In lithic analysis (a subdivision of archaeology), an eraillure is a small secondary flake removed from a lithic flake's bulb of force, which is a lump left on the dorsal surface of a flake after it is detached from a core of tool stone during the process of lithic reduction.
		The mechanics of eraillure formation are related to the propagation of a Hertzian cone[?] of force through the cryptocrystalline matrix of the stone, but the particulars are poorly understood.
		Eraillures form only when a hammerstone is used for lithic reduction, and then only occasionally; use of soft hammer[?] fabricators made from bone, antler, and wood produce different flake characteristics.

	GLOSSARY OF TERMS USED IN LITHIC ANALYSIS
		Sometimes the eraillure flake adheres to the core in the bulbar scar.
		The eraillure flake leaves no scar on the core, but always leaves a scar on the ventral surface of the flake.
		The eraillure flake is convex/concave (like a meniscus lens), has no distinct features on the "dorsal face", but may contain compression rings on the bulbar face.

		Termination type is a characteristic indicating the manner in which the distal end of a flake detached from a core.
		Eraillures, also referred to as "bulbar scars", are tiny flake scars that appear on some bulbs of applied force.
		Many secondary and tertiary flakes display dorsal flake scars, which are simply the markings left behind by flakes detached prior to the detachment of the subject flake.

		Found on lying on the surface in the southeast quadrant of the property looking like any other rock until Paul picked it up.
		The ventral surface clearly shows a bulb of percussion, a striking platform, and an eraillure.
		The tool is unifacially retouched from the ventral side, with the roughly parallel flakes being removed from three edges of the dorsal surface shown in the photo.

		Flakes have specific features identifying them as the result of human hands rather than natural processes.
		All flakes typically have a striking platform (A), bulb of percussion (B), eraillure (C), radial fissures (D), ripple marks (E), and negative flake scars on the dorsal side from earlier flake removals (F).
		You can think of these features in terms of dropping a rock in a still pond: the rock hitting the water (A), the splash (B), the drops that fly away from the splash (C), the drops that fall back near the splash (D), and the concentric waves moving outward (E).

	arthritis pain relief - Lithic reduction (Site not responding. Last check: 2007-10-23)
		In this kind of fracture, a cone of force propagates through the material from the point of impact, eventually removing a full or partial cone; this result is familiar to anyone who has seen what happens to a plate-glass window when struck by a small object, such as an airgun projectile.
		The partial Hertzian cones produced during lithic reduction are called flakes, and exhibit features characteristic of this sort of breakage, including striking platforms, bulbs of force, and occasionally eraillures, which are small secondary flakes detached from the flake's bulb of force.
		Flakes are often quite sharp, with distal edges only a few molecules thick, and can be used directly or modified into other types of tools such as spokeshaves and scrapers.

		The bulbs of percussion also sometimes had eraillures, small chips removed by the force of impact.
		In addition to the striking platform, bulb of percussion, and eraillure, some of Ribeiro’s specimens had several long, vertical flakes removed in parallel, something not likely to occur in the course of random battering by the forces of nature.
		The ventral surface of the flint flake shows “a large striking platform, bulb of percussion, and eraillure.” Sandstone, just like that found at the base of Monte Redondo, adhered to the dorsal surface.
