The rock outcroppings, bluffs, cliffs and general geologic terrain near Red Hill are an area of active scientific research in Paleozoology, Paleobiology and geobiology — as the area was a sizable inland freshwater lake about 375 mya[2] containing the earliest known soil building ecology and forest in the world. According to the 2005 "The Evolution of Our World: New Frontiers" episode of the "Miracle Planet" series tracing current earth science researchers thinking on the development of our earth, the Geologic record at Red Hill[2] suggests the area contained the planets' earliest known forest[2] during the Devonian, consisting mainly of the species Archaeopteris[2]. The animal fossil record at Red Hill include important finds suggesting their respective early species were evolving features such as fins to stubby appendages — precursors to legs[2] — specialized for land and presupposing development of lung like organs[2], whilst the intermixed plant fossils show the area was likely a swampy shallows or mixed landscape containing shallows when the forest was prevalent[2]. A researcher[3] at the Academy of Natural Sciences theorized for the production that a apex predator tooth in the nearby beds from deeper waters suggests the migration of lung fish to land may have been to avoid predation by such threats — one of the armored fishes of the late Devonian period[2].
