Clam fossils divulge secrets of ecologic stability
ITHACA, N.Y. - Clam fossils from the middle Devonian era – some 380 million years ago – now yield a better paleontological picture of the capacity of ecosystems to remain stable in the face of environmental change, according to research published today (May 15) in the online journal PLOS ONE.
Trained to examine species abundance – the head counts of specimens – paleontologists test the stability of Earth's past ecosystems. The research shows that factors such as predation and organism body size from epochs-gone-by can now be considered in such detective work.
