The lowermost unit of the G\u00fcag\u00fcaqu\u00ed Group, a sequence of sandy limestones and shales, dates to the Late Cretaceous period; Turonian epoch, and has a maximum thickness of 90 metres (300\u00a0ft).Fossils of Yaguarasaurus columbianus, said to be found in the time-equivalent La Frontera Formation (listed as “La Frontera Member”), were actually recovered from the Hondita Formation as the stratigraphic unit present in the Quebradas El Ocal and Itaibe, Huila.

The age has been estimated on the basis of ammonites to be Turonian.[2] Stratigraphically, the formation is time equivalent with the lower parts of the Chipaque, La Luna and La Frontera Formations.[5] The formation was deposited in a relative highstand sequence with an oceanic oxygen depletion event, sharply marked in Colombia and characterised by the appearance of calcareous concretions with a thick pyrite rim.[6]Yaguarasaurus[edit]Fossils of Yaguarasaurus columbianus were described as coming from the “La Frontera Member”, part of the “Villeta Formation”, in the Quebrada El Ocal, 26 kilometres (16\u00a0mi) southwest of Neiva, Huila,[7][8] and in the Quebrada Itaibe 78 kilometres (48\u00a0mi) southwest of Neiva,[9] although in these areas the Hondita Formation is mapped.[10][11]Outcrops[edit]Type locality of the Hondita Formation in TolimaThe type locality of the Hondita Formation is located in Piedras, Tolima.[1] Other outcrops of the Hondita Formation have been noted east of the Magdalena River northeast of Honda,[12] west of Nari\u00f1o,[13] west across the Magdalena River in San Luis, Tolima,[14] between the Tetu\u00e1n and Salda\u00f1a Rivers west of Coyaima and east and west of Ataco,[15] to the east of the Prado River reservoir,[16] north and west of Aipe,[17] surrounding Alpujarra, Tolima,[18] south of Palermo, Huila, displaced by the Bach\u00e9 Fault,[19] east of Iquira,[10] north of Yaguar\u00e1,[11] south of La Plata where the formation is cut by the Itaibe Fault,[20] a small patch east of Gigante, Huila,[21] northwest and northeast of San Agust\u00edn,[22] and north of Timan\u00e1 surrounding the Magdalena River.[23]Regional correlations[edit]See also[edit] Geology of the Eastern Hills Geology of the Ocet\u00e1 P\u00e1ramo Geology of the Altiplano Cundiboyacense Geology of the Middle Magdalena ValleyReferences[edit]^ a b c Acosta & Ulloa, 2002, p.23^ a b Acosta & Ulloa, 2002, p.24^ P\u00e1ramo, 2001, p.68^ Patarroyo, 2011^ Acosta & Ulloa, 2002, p.22^ Villamil, 2012, p.173^ ‘Yaguarasaurus columbianus’ in the Paleobiology Database^ Yaguarasaurus columbianus at Fossilworks.org^ P\u00e1ramo Fonseca, 2000, p.124^ a b Plancha 344, 1999^ a b Plancha 345, 1999^ Plancha 207, 2010^ Plancha 245, 1999^ Plancha 264, 2002^ Plancha 282, 1993^ Plancha 283, 2009^ Plancha 302, 1993^ Plancha 303, 2002^ Plancha 323, 1998^ Plancha 366, 1998^ Plancha 367, 2003^ Plancha 388, 2002^ Plancha 389, 2003Bibliography[edit]Acosta, Jorge E., and Carlos E.
