Five stories that have North Texas talking: the Perot Museum of Nature and Science scores a mammoth donation, the purchasing power of $100 in Texas, Dallas is a pretty sleep city, and more.

The Perot Museum of Nature and Science has acquired an almost complete mammoth skeleton. The skeleton was discovered in Ellis County on a private property, and is estimated to be anywhere from 20,000 to 60,000 years old, reports CultureMap Dallas. Experts speculate that the mammoth was female due to its small size of eight to 9 feet and other anatomical factors. The skeleton will be transported to the Perot sometime in September.

• How much purchasing power does $100 have in Texas?

• Welcome to Dallas, the city that likes to sleep a lot.

About 75 percent are also asleep by midnight each weeknight. [Dallas Observer]
• American Airlines will stop posting fares on Orbitz, the Dallas Business Journal reports.  The Fort Worth-based airliner tried working out a deal with the company, but American president Scott Kirby said using the service was too expensive. The two companies have had disagreements in the past. In 2011, American sued Orbitz and Travelport, claiming the companies were engaging in anti-competitive behavior. The suit was mostly thrown out. The year prior to that, American also asked Expedia to remove its fares from the website. Travelers who have already purchased American flights through Orbitz shouldn’t worry – the tickets are still valid – but reservation changes will have to be done through the airline’s website. Fares for U.S. Airways flights won’t be found on the travel website starting Sept. 1
