In squalodonts the teeth resemble those of the archaic whales, Archaeoceti, with conical incisors anteriorly and low-crowned, serrated teeth posteriorly. Squalodontidae Squalodontidae or the shark-toothed dolphins is an extinct family of large toothed whales who had long
California Endangered Species Act mortality, as opposed to habitat alteration that adversely impacts the listed species. The year 1970 brought about two major California enactments: the California Species Preservation Act, and the California Endangered Species Act. The Species Preservation Act tasked the Department with creating an inventory of all fish and wildlife that could be considered rare or endangered. The list was to be reported to the Legislature along with suggestions on methods for protection. The California Endangered Species Act put into effect the Department’s authority to determine the designation under which wildlife was labeled as “rare” or “endangered” and provided restrictions on the
