Question: In what year was the lower jaw of an Anachlysicitis found in the Vilavieja Formation? Passage:Anachlysictis gracilis is an extinct carnivorous mammal belonging to the group Sparassodonta, which were metatherians (a group including marsupials and their close relatives) that inhabited South America during the Cenozoic. Unlike other remains assigned to the family Thylacosmilidae (a group of metatherian predators equipped with "saber teeth") that had been found previously, Anachlysictis is the first record of such borhyaenoids in northern South America, and also most primitive and ancient in the family (in fact, is the first confirmed record that did not belong to the genus Thylacosmilus, until the official publication of Patagosmilus in 2010). This species was found in the Villavieja Formation in the area of La Venta in Colombia, a famous fossil deposit in the Middle Miocene (Laventan; 13.8-11.8 million years ago), based on fragments that include a front portion of the lower jaw, with an incipient molar tooth and a piece of carnassial from the front of the maxilla.

Question: How many copies of the duet produced by Gary Klein were sold? Passage:Having left Casablanca Records, with whom she had had some of the biggest selling and most popular hits of the disco era in the 1970s, Summer had signed to Geffen Records in 1980 and had continued working with Giorgio Moroder and Pete Bellotte, with whom she had written the vast majority of her hits. However, label owner David Geffen had been disappointed with the chart performance of the 1980 The Wanderer, Summer's debut album for Geffen and rather than release the followup; I'm a Rainbow which Summer had recorded with Moroder/Bellotte in 1981. Geffen had Summer record a new album with Quincy Jones from whom a production credit given Jones' track record particularly his work with Michael Jackson Geffen felt would guarantee a commercial smash. The resultant Donna Summer album was the first time the singer had worked with a producer other than Moroder and Bellotte since 1974 save for the one-off track "Down Deep Inside (Theme from "The Deep")" which was produced by John Barry for the film The Deep, and the "No More Tears (Enough is Enough)" duet with Barbra Streisand which was co-produced by Gary Klein of The Entertainment Company.
