It is likely that dogs were afforded special mortuary treatment because of their closeness with humans and high status as pets. It is also possible that in some instances, they served as substitutes for human sacrifice (Hill 2000:386- 387). Hill (2000) studied 164 interments of birds, canids, and bears dating from A.D. 200-1450 in the southwestern U.S. and determined that animal burials fell into three categories: 1)“animal sacrifice and disposal as ceremonial trash;” 2)“dedicatory interment,” as an offering for special occasions (e.g., building a structure); and 3) “simple interment or expedi- ent disposal,” for all other interments (Hill 2000:363-364). Walker (1995) applied the term “ceremonial trash” to worn- out ritual objects found in an archaeological context. These objects were disposed of in a manner suitable to sacred objects, a practice which appears to be cross-cultural and continues today. Many animal burials would be classified under Hill’s first category as ceremonial trash or animal sacrifice. These interments show intentional killing before disposal and are recovered either in association with human burials (Haag and Heizer 1953; Heizer and Hewes 1940; Hill 2000; Mellink 1966) or from other sacred locations outside habitation areas (Hill 2000). After the animals are used for a ceremonial purpose, they are ritually disposed of in sacred ground (hence, “ceremonial trash”). For example, Hill studied 459 avian interments and concluded that they were chiefly ceremonial trash. She argues that the birds were sacrificed for their feathers and were buried because their use-life had ended (Hill 2000:378). Other animal burials are associated with human burials and may constitute substitutes for human sacrifices. For example, at sites located in central California dating to the Late Culture, a fully articulated bear skeleton (Ursus americanus) was found at the west edge of a cemetery area of site C.138, a badger (Taxidea taxus neglecta) was found within a few inches of a flexed human burial at site $.60, and several coyotes (Canis latrans) were found near or within human burials (Heizer and Hewes 1940). These interments are regarded as ceremonial, particularly because many of the animals were transported long distances and they are in association with a sacred site, which is a burial or a cemetery in this case. Ethnographic accounts reveal that central California tribes kept coyotes, deer, and bear as captive pets and may have had emotional attachments to them. Florida Animal Interments Most animal burials recorded in Florida also may be categorized as ceremonial trash. As is true elsewhere, dog interments are the most common type of animal interment in Florida (Table 1), and dogs are thought to have been kept as pets by Florida tribes (Wheeler 1992b). This contrasts with what Hill (2000) found in the Southwest: out of 90 canid interments, which contained | 15 individuals, she concluded that most were dedicatory offerings, found in pits or under the floors of kivas or other structures (Hill 2000:379, 386). North of Lake Okeechobee, animal interments, mostly dog burials, are known from several sites. For instance, at the Lighthouse Mound (8NA3) on Amelia Island, Moore (1896, in Mitchem 1999:38) recovered a dog skeleton in the burial mound with many human bones. At the Hutchinson Island site (8MT37) in Martin County, seven dog burials were found within a burial mound (Carr and Steele 1993:12). There are six sites in southern Florida with animal burials (Table 1). Numerous animal burials were reported from the Palmer Burial Mound (8SO2) at the Palmer site complex near Sarasota, Florida (Bullen and Bullen 1976). Four dog burials anda “ceremonial” alligator interment were found among about 400 human burials. Three of the dog burials were in close proximity to one another and were located three to seven feet northwest of the alligator burial. They were laid in shallow pits on their side, and one burial contained two dogs. The alligator was laid in a shallow pit above two human burials and con- tained several grave goods.
