Manatees appear on hundreds of license plates, attract hordes of tourists, and expose the uneasy relationships between science and the law and between freedom and responsibility like no other animal. As passions have flared and resentments have grown, the battle over manatee protection has evolved into a war, and no reporter has followed the story more closely than Craig Pittman, the first environmental writer to explore the complex history, culture, and science of the controversies and concerns surrounding this remarkable creature. With an abiding interest in the uncertain fate of this unique species, Manatee Insanity provides the first in-depth history of the attempts to provide legal protection for the manatee. Pittman follows Florida’s gentle giants through time and space, detailing interactions with a variety of human actors, from Jacques-Yves Cousteau to Jeb Bush to Jimmy Buffett, from a popular children's book author to a federal lawman who dressed in a gorilla suit for the ultimate undercover assignment.

A complex pattern of ontogenetically-related and ontogeny-independent variation produced a mosaic of morphotypes, which show greater diversity than previously recorded within trilobite species. There is considerable variation within collections made from single beds. Variations of characters among collections are mosaic, and are clinal in some cases. Patterns of variation within Dikelocephalus cannot be related to lithofacies occurrence. There are no obvious temporal variations in D. minnesotensis within the St. Lawrence Formation, but some Dikelocephalus from the underlying Tunnel City Group may belong to a different taxon. The validity of this early taxon is questionable due to a lack of available material. The mosaic pattern of variation in Dikelocephalus mimics that documented at higher taxonomic levels in primitive libristomate trilobites, and helps explain difficulties in providing a workable taxonomy of primitive trilobites. Results caution proposition of evolutionary scenarios that do not take account of intraspecific variation. The recovery of dorsal shields of Dikelocephalus permits the first detailed reconstruction of the entire exoskeleton. The systematics of the genus is revised and twenty-five species are suppressed as junior synonyms of D. minnesotensis.
