Given that numerous rebbachisaurids inhabited latitudes that would are tropical to subtropical in the Middle Cretaceous, this pneumaticity could possibly have helped the animals cope Along with the extremely significant temperatures. In accordance with Ibiricu and colleagues, this adaptation could be a purpose why rebbachisaurids ended up the only group of diplodocoids that survived into your Late Cretaceous.[21]
Initial discoveries of Nigersaurus fossils day again on the nineteen sixties, nonetheless it wasn't right up until the seventies that far more finish stays have been uncovered. These continues to be ended up formally examined and described by paleontologist Paul Sereno and his crew in 1999.
