Paraproetus girvanensis TrilobiteDescription: This is a Paraproetus trilobite that would be termed in common parlance a “roller”, or enrolled example. Trilobites would roll up as a defense from threats in the environment, which may have been this example’s last move. The Proetida were true “survivors’, being the only trilobites to survive into the Permian.
