Question: How many years did Major General Haislip serve in the military? Passage:On 15 May 1942, five months after the United States entered World War II, the 85th Infantry Division was ordered into active military service at Camp Shelby, Mississippi, under the command of Major General Wade H. Haislip. Divisions in the U.S. Army at that time were "triangularized" with three combat regiments instead of the four regiment structure "square division" used during World War I. The 340th Infantry Regiment was redesignated as the 410th Quartermaster Battalion and left the division. Basic infantry training was begun in June 1942 at Camp Shelby, Mississippi. In April 1943, it participated in large-scale army training in the Louisiana Maneuvers near Leesville, Louisiana. In August, the division was moved to Camp Coxcomb, California for desert warfare training. In October, the division was transferred to Fort Dix, New Jersey, for final preparations before shipment overseas. Major General John B. Coulter was transferred as commander and retained this position throughout the war. The Assistant Division Commander (ADC) throughout the war was Brigadier General Lee S. Gerow.

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.
