Abstract	RESUMEN La seccion de la quebrada Bambuca (Aipe - Huila) posee una buena exposicion de los depositos del Cretacico del Valle Superior del Magdalena. De la parte alta de la Formacion Hondita se recolectaron Acanthocerassp. y Rhynchostreon sp. del Cenomaniano superior. Dentro del segmento inferior de la Formacion Loma Gorda se hallaron Choffaticeras (C.) cf. segne, Fagesia cf. catinus, Neoptychites cf. andinus, Mitonia gracilis,Morrowites sp., Nannovascoceras ? sp., Quitmaniceras ? sp., Benueites ? sp. junto con Mytiloides kossmati,M. goppelnensis y Anomia sp. del Turoniano inferior. Estratigraficamente arriba aparecen Paramammites? sp., Hoplitoides sp. H. ingens, H. cf. lagiraldae, Codazziceras ospinae, Allocrioceras sp., que pueden estar representando entre el Turoniano inferior y medio. Para la parte alta de este segmento se encontraron Prionocycloceras sp. P. guayabanum, Reesidites subtuberculatum, Subprionotropis colombianus, Mytiloidesscupini, Dydimotis sp., Gauthiericeras sp., Anagaudryceras ? sp., Eulophoceras jacobi, Paralenticeras sieversi,Hauericeras cf. madagascarensis, Peroniceras (P.) subtricarinatum, Forresteria (F.) sp., Barroisiceras cf.onilahyense, Ankinatsytes venezolanus que abarcan entre el Turoniano superior y el Coniaciano. Con base en lafauna colectada no es posible establecer los limites Cenomaniano/Turoniano y Turoniano/Coniaciano. Palabras clave : Amonitas, Cretacico superior, Valle Superior del Magdalena, Aipe-Huila-Colombia. UPPER CRETACEOUS AMMONITE SUCCESSION (CENOMANIAN –CONIACIAN) RELATED TO THE UPPER HONDITA AND LOMA GORDAFORMATIONS ALONG THE BAMBUCA CREEK, AIPE - HUILA(COLOMBIA, S.A.) ABSTRACT The Bambuca 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. Keywords: Ammonites, upper Cretaceous, Upper Magdalena Valley, Aipe-Huila-Colombia
