EurekAlert [USA], 29-Feb-2012
Millions of years after its extinction, Triceratops is inciting
controversy about how to classify the ancient animals. New analysis,
published Feb. 29 in the open access journal PLoS ONE, suggests that the
specimens in question should be classified into two separate groups,
Triceratops and Torosaurus, and are not individuals of different ages
from the same genus, as others have proposed.
