Figure F4. Vincentown (upper Paleocene), Hornerstown (lower to lowermost upper Paleocene), and Navesink (Maastrichtian) Formations, Ancora Site. Numbers in Ma are Sr isotopic age estimates (Table T2). The key for symbols is given in Figure F2. Foram. = planktonic foraminifer biostratigraphy; Nannofossils = calcareous nannoplankton biostratigraphy; FAD = first appearance datum; LAD = last appearance datum; Fm. = Formation; MFS = maximum flooding surface; CIE = correlative to the carbon isotopic excursion.
