So we sort of realised that we've got two new spinosaurids.

所以我们意识到，发现了两种新棘龙。

The semi-aquatic spinosaurids, for example, lived on the remnants of Gondwana.

例如，半水生棘龙类 生活在冈瓦纳的遗迹上。

Likewise, with the disappearance of the phytosaurs, spinosaurids and crocodiles were able to move in to dominate as freshwater predators.

同样， 随着植物龙类的消失，棘龙科和鳄鱼得以迁入并成为淡水捕食者。
