Asaphus kotlukoviDescription: A well-inflated example of a medium-eyestalked member of the Asaphidae, this is Asaphus kotlukovi. The region in which these trilobites lived was subject to dramatic changes in salinity and turbidity, and the trilobites were able to make rapid (geologically speaking) evolutionary adjustments. These adjustments were thought to be able to allow them to see both predator and prey more easily.. It has a flattened matrix base which allows for various display modes.
