This rim sherd is from the Lawson site, an Indigenous village inhabited 500 years ago in London, Ontario. Archaeologists refer to this type of decoration, with oblique incised lines around the collar and horizontal lines on the neck, as Pound neck style. This sherd also displays a castellation, an appended relief decoration common on vessels of this time period. As ceramic is baked clay, it preserves well in archaeological contexts and is a common archaeological find. Over 100,000 ceramic sherds have been found on the Lawson site, from pottery vessels and pipes.
