The Floresta Formation ( Spanish : Formación Floresta , Df) is a geological formation of the Altiplano Cundiboyacense in the Eastern Ranges of the Colombian Andes . The sequence of siltstones , shales , coquinas and sandstone beds dates to the Devonian period; Late Emsian , Eifelian and Early Givetian epochs, and has a maximum thickness of 600 metres (2,000 ft). The unit is highly fossiliferous ; brachiopods , bryozoans , gastropods , trilobites , corals and bivalves have been found in the Floresta Formation. Some fragments of Placoderm fish fossils were found in the Floresta Formation, while the overlying Cuche Formation is much richer in fish biodiversity.
9-449: The formation was first described as Floresta Series by Olsson and Carter in 1939. The current definition was given by Botero in 1950. The formation is named after Floresta , Boyacá , where the formation outcrops . The Floresta Formation is characterized by a lower sequence of shales and ochre to beige siltstones with alternating coquinas , while the upper part consists of siltstones with sandy beds. The Floresta Formation overlies
18-2810: A transgressional and regressional epicontinental marine environment at the edge of the Paleo-Tethys Ocean . The uppermost part of the formation has been deposited in a deltaic setting, with the lower sequence formed in a coral reef environment.

27-756: Is also found in the upper course of the Chicamocha River in the eponymous canyon . Many of the fossils are on display in the paleontological museum of Floresta. Floresta, Boyac%C3%A1 Floresta is a town and municipality in Boyacá Department , Colombia , part of the Tundama Province , a subregion of Boyacá. Floresta is situated on the Altiplano Cundiboyacense in the Eastern Ranges of
36-454: Is an extinct genus of tabulate coral characterized by polygonal closely packed corallites (giving it the common name "honeycomb coral"). The walls between corallites are pierced by pores known as mural pores which allowed transfer of nutrients between polyps. Favosites , like many corals, thrived in warm sunlit seas, feeding by filtering microscopic plankton with their stinging tentacles and often forming part of reef complexes. The genus had
45-616: The El Tíbet Formation and is overlain by the Cuche Formation . The age has been estimated to be Late Emsian to Early Givetian . Stratigraphically, the formation is time equivalent with the Portachuelo Formation around Quetame . The Onondaga Formation of New York is considered time equivalent too. The formation contains concretions and a high diversity of fossils . The formation was deposited in
54-585: The Colombian Andes . It borders Santa Rosa de Viterbo , Cerinza and Betéitiva in the north, in the east Busbanzá and Corrales in the west Santa Rosa de Viterbo and Nobsa in the south. Before the Spanish conquest of the highlands of Colombia, the area of Floresta was inhabited by the Muisca , organized in their Muisca Confederation . In those days Floresta, together with Santa Rosa de Viterbo,
63-630: The Colombian fruit uchuva is produced in Floresta. The municipality grows grapes, races Riesling and Pinot Noir for wine production, uncommon in tropical Colombia. Livestock and dairy farming are other production areas. The fossiliferous Devonian Floresta Formation is named after Floresta and has provided many trilobites and brachiopod fossils. 5°55′N 72°55′W / 5.917°N 72.917°W / 5.917; -72.917 Favosites See text Favosites
72-544: The Floresta Formation. Colombianaspis carvalhoae gen. et sp. nov. , Schizobolus pilasiensis sp. nov. and Tarijactinoides sp. nov. , were newly described in 2015. The Floresta Formation is found at the Floresta Massif around its type locality in Floresta, Boyacá, stretching to the south until between Busbanzá and Nobsa and to the west close to Belén , Cerinza and Tutazá . The formation
81-495: Was called Tobasía which is still the name of a corregimiento of the village. Tobasía was ruled by a cacique loyal to the ruler of Tundama , present-day Duitama. Modern Floresta was founded in 1818, three years before the independence of Colombia from the Spanish Empire. Floresta means "between the flowers". Main economical activity of Floresta is agriculture , predominantly potatoes , maize and barley . Also
