Vestiges of soft tissue preserved in a 70-million-year-old Mongolian fossil suggest that some dinosaurs strained small bits of food from the water and mud of streams and ponds, just as modern ducks, geese, and flamingos do.

Fossil skull (top) bears a sieve-like plate (seen in detail at bottom), suggesting that the dinosaur Gallimimus and its close kin were filter feeders.
