Smilodon Quadsuit

At the Los Angels National History Museum they have a show with the main star being a Smilodon (aka Saber toothed CAT!! NOT TIGER !!). Smilodon is a member of the extinct Machairodontinae which is a branch of the True cat family tree and is not closely related to any living feline. As for "behavior" it was probably more like lions living in groups due to fossil evidence of healed injuries and other issues that would have spelled doom for a solitary hunter.

The man standing next to the cat is a puppeteer with a smaller Smilodon cub running around her. the story was that the pair is a mother and cub and how they may have interacted.
