PARDO JARAMILLO, Mauricio. Report on the finding of remains of Hilarcotherium sp. (Mammalia, Astrapotheria) and associated material in a new fossil locality in the Lower Valley of Magdalena, Zapatosa wetlands, Cesar, Colombia. Rev. acad. colomb. cienc. exact. fis. nat.

In April 2018, the “José Royo y Gómez” Geological Museum received a report on the discovery of paleontological material in the vicinity of La Mata village, in the municipality of Chimichagua (Cesar), on the banks of the Zapatosa wetlands. The material collected by local residents included a large alligator tooth (Purussaurus), remains of (Podocnemididae?) and matamata turtles (Chelus), and a maxillary fragment of Hilarcotherium sp. (Mammalia, Astrapotheria) known so far for the findings of the type species Hilarcotherium castanedaii (Vallejo-Pareja, et al., 2015) in the strata of the Honda Group (La Victoria Formation) in the town of Purificación, Tolima, and of Hilarcotherium miyou (Carrillo, et al., 2018) from the Castilletes Formation in the southeast area of La Guajira peninsula. Additionally, this report is the first record of Miocene continental rocks in this region of the country.

Keywords : Astrapotheria; Hilarcotherium castanedaii; Hilarcotherium miyou; Miocene.
