Palaeontologia Electronica 21.2.2T 1-15.1935-395210.26879/815http://hdl.handle.net/10141/622881This paper outlines the history of air-abrasion (also known as airbrasion) as a paleontological preparation technique and evaluates various powders and their properties. It explores the rationale behind the selection of abrasive powders and presents, for the first time, trench-scatter experiments through Scanning Electron Microscope (SEM) photography and three-dimensional (3-D) profiling. This article also offers general practical advice and details the results of an international survey of practising fossil preparators.openAccesshttps://creativecommons.org/licenses/by/4.0/Journal Article1094-8074Palaeontologia Electronica2020-12-2921221.2.2Tair-abrasivepreparationfossilconservationair abrasion
