バーナム・ブラウン
Reports of gastroliths, or stomach stones, in "Claosaurus" are actually based on a probable double misidentification. First, the specimen is actually of "Edmontosaurus annectens". Barnum Brown, who discovered the specimen in 1900, referred to it as "Claosaurus", because "E. annectens" was thought to be a species of "Claosaurus" at the time. Additionally, it is more likely that the supposed gastroliths represent gravel washed in during burial.
