[Q]: Question: What other types of fossils have been found in the Villaieja 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.

[Q]: Question: What team did the captain that left Stoke in 2007 go to? Passage:He joined fellow Championship side Stoke City for a 225,000 fee in August 2006. He was made captain when Michael Duberry left in January 2007 and Stoke went on to narrowly miss out on a play-off place. With Stoke not being promoted Higginbotham again decided to hand in a transfer request to help force through a move to Sunderland. He spent one season at the Stadium of Light before returning to Stoke in 2008. He became a vital member of Tony Pulis' squad as Stoke established themselves in the Premier League. He scored the winning goal in the FA Cup quarter-final against West Ham United but missed out on both the semi-final and the final due to a knee injury. After his recovery he struggled to force his way back into the side and spent time out on loan to Nottingham Forest and Ipswich Town before joining Sheffield United on a free transfer in January 2013. After eight months at Bramall Lane, he left to join Conference Premier side Chester before ending his career with a short spell at Altrincham.

[Q]: Question: Did Hamasaki's pop ballad or more rocking song have a better chart position? Passage:It opens with two club-driven tracks: an interlude titled "Bridge to the Sky", and the promotional titular song. "Disco-munication" is the second interlude on the album, blending "sophisticated" electric guitars with electronic music. "Energize" is another electronic track, and is one of the only numbers on the album that include English phases ("Put your hands up together, keep your heads up forever, let me sing forever,"). The fifth track "Sparkle" was noted as a club song with an electronic arrangement, similar to the follow-up song "Rollin'". Both tracks feature autotune and vocoder pro-tools, a first for Hamasaki. The album's sixth track, "Green", shows a departure from the album's earlier electronic style; it focuses more on older traditional Japanese sound, alongside instrumentation of electric guitars and drums. The album's third interlude, "Load of the Shugyo", was described as an "atmospheric" number with heavy rock instruments in its composition. Rock music is then influenced on the following tracks "Identity"a song that discusses about self-confidencethe single "Rule", and the tune "Love 'n' Hate", which talks about the effects of lust. The album's fourth and final interlude "Pieces of Seven" was noted for its "atmospheric" sounds of an ocean, until the second half of the track diverges into a harder rock style. "Days" is the album's first pop ballad, and is described as a love song. It closes with the ballad "Curtain Call", which features a choir and piano riffs throughout its composition.
