Rebbachisaurids are the latest known sauropod dinosaurs outside the titanosaur lineage. Cienciargentina is a rebbachisaurid from the Late Cretaceous, making it among the most recent. It had many hollow bones, and likely had batteries of teeth used for chewing, a rebbachisaurid feature unique among sauropods. © TotalDino · CC BY 4.0 · Wikimedia
