The "Sudden Explosion" of Animal Fossils about 600 Million Years Ago: Why?
Kaveski, Sharon; Margulis, Lynn
American Biology Teacher, v45 n2 p76-82 Feb 1983
Discusses the "sudden explosion" of animal fossils during the Cambrian era, suggesting that the "explosion" is a result of organic evolution, leading to remarkably preservable calcareous skeletons. Suggests that earlier organisms were soft-bodied and consequently were poorly preserved in the fossil record. (JN)
