The Paleoindian period dates between 16,000 and 10,000 years ago. It generally corresponds to the end of the Ice Age. The land that eventually became Pennsylvania was not the lush forest Native Americans enjoyed at the time of European contact. Instead it was an open spruce forest with only a few broad leafed trees such as oaks along the major streams and rivers. This environment did not contain nearly the food resources that were available to Native Americans during later time periods.
A major problem with determining the Paleoindian diet is the very poor preservation of organic remains such as animal bones or plant parts in the eastern United States. Unless they are partially burned, these are hardly ever preserved in the archaeological record. Much of the early speculation on the diet of Paleoindians was based on archaeology conducted in the western United States. Based on archaeological sites excavated in the west that contained the remains of mammoth, mastodon and extinct bison, archaeologists believed for a long time that Paleoindians in Pennsylvania were highly mobile, big-game hunters. In Florida, there is a growing body of data indicating mammoth steaks were part of the Paleoindian subsistence pattern. It was assumed that Paleoindians also hunted a variety of smaller animals and ate a wide variety of plant foods, but a significant part of their diet was based on now extinct Ice Age animals. However, in the Northeast, there is no association of extinct animals with Paleoindian artifacts. In fact, the East (north of Florida) does not contain much data to address the issue of diet. Therefore, answering the question of what Paleoindians ate has been a major obstacle to understanding their adaptation.

These two sites present very different pictures of Paleoindian subsistence patterns and the Paleoindian lifestyle. However, when we begin to examine Paleoindian sites to the north in New England and Canada or to the south in Virginia and the Carolinas, a pattern begins to emerge. There are several sites in New England that are similar to Shoop with large numbers of spear points and hide scrapers made in stone that was transported hundreds of miles. At several of these sites fragments of burned caribou bone has been recovered verifying the exploitation of this animal. To the south, Paleoindian habitation sites are small, containing small numbers of finished spear points, a variety of tool types and these are frequently made in stone from sources less than 100 miles away. These two types of sites seem to represent different subsistence patterns; one exploiting a variety of plants, animals and fish and the other utilizing at least some of their time exploiting migratory game such as caribou, elk, or migratory birds.
Pennsylvania is on the border of these two adaptations. During the Paleoindian period in both regions people moved their camps in a seasonal pattern or “round” to the locations of predictable food resources, such as along the migration routes of caribou, water fowl, or anadromous (spawning) fish. The seasonal round also included a number of plant-food collecting sites although we do not know much about these. Compared to later groups, their seasonal round was very large covering over 100 miles. In the northern part of the state there is evidence for the hunting of migratory caribou. In the southern part of state, general foraging in the form of gathering seeds, nuts, berries, roots and fishing was more common. Their subsistence strategy involved collecting the most concentrated foods and those that did not require any special processing. Their adaptation involved traveling long distances to more easily exploitable resources. The Ice Age was a harsh time, but human populations were very low and there was little competition among bands over the easily exploitable foods. Although, the overall quantity of food in this environment was low, the human population was also small permitting their choice of foods that were the easiest to collect. Although hunting probably dominated Paleoindian subsistence in Pennsylvania, they were not primarily big game hunters and approximately 40% of their diet was from seeds, nuts, berries and roots. This is in contrast to the Archaic period when plant foods dominated the diet.
