The lifestyle of Archaeopteryx is difficult to reconstruct and there are several theories regarding it. Some researchers suggest that it was primarily adapted to life on the ground,[46] while other researchers suggest that it was principally arboreal.[47] The absence of trees does not preclude Archaeopteryx from an arboreal lifestyle as several species of extant bird live exclusively in low shrubs. Various aspects of the morphology of Archaeopteryx point to either an arboreal or ground existence, including the length of its legs and the elongation in its feet; some authorities consider it likely to have been a generalist capable of feeding in both shrubs and open ground, as well as alongside the shores of the lagoon.[44] It most likely hunted small prey, seizing it with its jaws if it was small enough, or with its claws if it was larger
