Fossils record ancient migrations and trilobite orgies
Date:3/16/2011

Brett and colleagues found evidence of another behavioral connection to modern arthropods long chains of trilobites apparently fossilized in mid-migration.

"The recent discovery of rows of more than a dozen specimens provides the oldest evidence of migratory queues similar to those seen in modern crustaceans," Brett said.

Taken together, the mass burials record an array of communal behaviors in ancient trilobites, comparable to those seen in some living crustaceans.
