Tongnanlong is a large mamenchisaurid sauropod dinosaur that lived in the Late Jurassic period of what is now China. Typical of mamenchisaurids, it had an extremely long neck, even by sauropod standards. Tongnanlong grew to approximately 25 m in length and weighed 20-30 t, making it one of the largest mamenchisaurids. © TotalDino · CC BY 4.0 · Wikimedia
