Template:Short description Template:Use Australian English Template:Use dmy dates Template:Infobox terrestrial impact site Goat Paddock is a 5 km-diameter near-circular bowl-shaped depression in a range of gently dipping Proterozoic sandstone in the Kimberley Region of northern Western Australia, 106 km west-southwest of Halls Creek. It is interpreted as an ancient meteorite impact crater, the evidence including breccia containing melted rocks, silica glass, shatter cones and shocked quartz.<ref name="Harms_1980">Harms J.E., Milton D.J., Ferguson J., Gilbert D.J., Harris W.K. & Goleby B. 1980.

AbstractTemplate:Dead link</ref><ref>Template:Cite Earth Impact DB</ref> Drilling shows that the crater is filled with about 200 m of ancient lake sediments containing Early Eocene pollen, this age thus giving a minimum estimate for the age of the crater itself.<ref name="Harms_1980"/> The crater is not perfectly circular, but slightly elongated in a north–south direction, suggesting that the projectile struck at low angle from either the north or south.
