Description
Trilobite Elrathia kingii 300 million years old from Utah. Incomplete 1 inch trilobite free from the matrix. It has very good definition. Similar to picture shown.
Elrathia kingii is a classic Middle Cambrian trilobite and possibly the most recognizable trilobite species in the world. They typically average a little less than an inch in length with very large individuals reaching about 2 inches. Elrathia’s body shape, mouth parts, and high concentrations suggest they are particle feeders, scavenging the ocean floor for food.
