First American National Bank was a subsidiary of First American Corporation, a financial institution based in Nashville, Tennessee, that served the states of Tennessee, Kentucky, Georgia and Virginia. It was headquartered in the First American Center in downtown Nashville. The bank began, in Nashville, as the American National Bank and later (1930), merged with James E. Caldwell's Fourth and First National Bank, to become First American National Bank. In 1971, construction of the First American Center (now the UBS Tower) in downtown Nashville resulted in the discovery of the skeleton of a sabertooth cat (Smilodon floridanus) within a cave beneath the bedrock. First American National Bank facilitated archaeological excavations at the site, funded radiocarbon analysis of the bone, and altered their original building design to protect the remnants of the cave, which still exist beneath the lower level of the building's parking garage. The cave is known variously as the "First American Cave" or by its official state archaeological site number, 40DV40. In 1997, the Smilodon skeleton from the First American site was the source for the logo of the Nashville Predators hockey team and the inspiration for their mascot, Gnash. Its name and logo disappeared in December 2000 when it was acquired by AmSouth Bancorporation, an institution based in Birmingham, Alabama, that was slightly smaller in size. First American had operated as a fully owned subsidiary of AmSouth for most of 2000. First American was sold after a series of unprofitable mergers, including one with Jackson, Mississippi-based Deposit Guaranty Bank that proved to be a hurdle the corporation could not clear financially. Deposit Guaranty was fully integrated into First American, but kept its name. This allowed FANB to gain significant market share in Mississippi, Arkansas, and Louisiana, though it did not operate these branches under the corporate brand, nor under recent the Iowa purchaser. First American's demise ended Nashville's storied history as a strong financial center. It, along with Third National Bank (now a part of SunTrust) and Commerce Union Bank (now a part of Bank of America), was once involved in a tight three-way battle for market share that ultimately helped all three banks expand well beyond their respective bounds. When the resources of the three could no longer stand the rapid expansion and numerous acquisitions, they all succumbed and merged with other banks. FANB, the largest of these three banks, was the only one to fold itself
