Ordovician: "Metopolichas platyrhinus ranks among the most unusual and visually stunning trilobites"

With its elongated body and outlandish sword-like headgear, Metopolichas platyrhinus indubitably ranks among the most unusual and visually stunning trilobites. Scientists think that this species used its elongated “nose” to stir up seafloor debris when searching for a meal. The specimen pictured is 4.3 inches (10.9 centimeters) long, nose included!
