Research on Sue the T-rex and Rare Plants

The video from The Field Museum covers three main topics: research on Sue the T-Rex's arm to understand its use, the discovery and study of the rare plant Thismia Americana by Norma Pfeiffer, and the classification of fossil beardogs. Sue's arm is being studied using advanced CT scans to uncover its function. Thismia Americana, a rare plant lacking chlorophyll, was discovered in Chicago and has a mysterious history. Fossil beardogs, ancient relatives of modern carnivores, were reclassified to better understand their evolutionary history. The video concludes with a wrap-up of the year's episodes.
