       Erketu is a genus of sauropod that is noted for having a very long neck in proportion to the rest of the body.‭ ‬So extreme was this neck that it likely took up at least half of the total body length.‭ ‬Despite this,‭ ‬other genera such as Mamenchisaurus may have had an even greater neck length in proportion to the body.
