Abstract
The Bambucá creek section (Aipe - Huila) shows a very good exposition of the Upper Magdalena Valley Cretaceous deposits. To the upper part of the Hondita Formation were recollected Acanthoceras sp. and Rhynchostreon sp. of the upper Cenomanian. Related to the lower segment of the Loma Gorda Formation were found Choffaticeras (C.) cf. segne, Fagesia cf. catinus, Neoptychites cf. andinus, Mitonia gracilis, Morrowitessp., Nannovascoceras ? sp., Quitmaniceras ? sp., Benueites ? sp., Paramammites ? sp. togheter with Mytiloideskossmati, M. goppelnensis and Anomia sp. of the lower Turonian. Following by Hoplitoides sp. H. ingens,H. cf. lagiraldae, Codazziceras ospinae, Allocrioceras sp. that can be representing between the lower and middle Turonian. To the upper part of this segment were collected Prionocycloceras sp. P. guayabanum,Reesidites subtuberculatum, Subprionotropis colombianus, Mytiloides scupini, Dydimotis sp., Gauthiericerassp., Anagaudryceras ? sp., Eulophoceras jacobi, Paralenticeras sieversi, Hauericeras cf. madagascarensis,Peroniceras (P.) subtricarinatum, Forresteria (F.) sp., Barroisiceras cf. onilahyense, Ankinatsytes venezolanus,with upper Turonian to Coniacian. According to the related fauna it is not possible to establish the Cenomanian/Turonian and Turonian/Coniacian boundaries.
