Fig. 22. Paleogeographic map at the Cretaceous/Tertiary boundary (after C.R. Scotese at http:// www.scotese.com/K/t.htm). The white lines indicate the present configuration of the continents. The star marks the Chicxulub impact crater in the northern Yucatan Peninsula, Mexico (Arenillas et al., 2006). The numbers denote sites with ammonites preserved near or at the K/T boundary: 1 5 New Jersey; 2 5 Maryland; 3 5 Mississippi, Tennessee, Missouri; 4 5 Texas; 5 5 Denmark; 6 5 Poland; 7 5 The Netherlands; 8 5 Bay of Biscay, France, Spain; 9 5 Tunisia; 10 5 Antarctica (for references, see table 4).

Fig. 3. Simplified stratigraphic section in the Manasquan River Basin, central Monmouth County, New Jersey, showing the upper part of the Tinton Formation and the lower part of the Hornerstown Formation. The unit at the top of the Tinton Formation (the Pinna Layer) contains a rich assemblage of fossils and represents an autochthonous deposit. (The fossils are not as abundant as illustrated.) The iridium spike occurs at the base of the Pinna Layer, and represents the Cretaceous/Tertiary boundary, assuming no postdepositional remobilization of iridium (but see text). A concentration of siderite nodules occurs at the base of the Hornerstown Formation and is associated with a hiatus. A ''Burrowed Unit'' is present at some downdip sites and is sandwiched between the top of the Pinna Layer and the overlying part of the Hornerstown Formation. The biostratigraphic ranges of five key species are illustrated on the right (D. iris 5 Discoscaphites iris; E. latecarinatus 5 Eubaculites latecarinatus; D. galeata 5 Deflandrea galeata; P. grallator 5 Palynodinium grallator; O. pulaskensis 5 Ostrea pulaskensis).

Fig. 21. Concentration of iridium (pg/g) at AMNH locs. 3372 (.) and 3391 (&), Manasquan River Basin, central Monmouth County, New Jersey. The scale (cm) is drawn such that 0 cm marks the boundary between the Tinton and Hornerstown formations. The highest concentration of iridium occurs at the base of the Pinna Layer, but the highest non-reworked ammonites occur approximately 20 cm higher up, at the top of the Pinna Layer.
