- Title
Existence of Romer's Gap.
- Abstract
The article addresses gaps in time during which vertebrates disappear from fossil records. "Romer's Gap," named for paleontologist Alfred Romer, refers to a gap in vertebrate creatures, amphibians, moving from ocean to land. New research, led by paleontologist Peter Ward of the University of Washington, found a similar gap, during the same period, among nonmarine arthropods. The University of Washington researchers believe that a drop in oxygen content in the Earth's atmosphere is responsible.
