Henodus was a peculiar placodont from the Late Triassic of Germany that actually was a sauropterygian - that group of marine reptiles that Atopodentatus might be related to.

Henodus 是德国晚三叠世的一种奇特的板齿兽，它实际上是一种蜥脚类动物——可能与 Atopodentatus 有亲缘关系的那群海洋爬行动物。

As a relative of the sauropterygians, it seemed safe at the time to say that it was probably a carnivore, eating tiny invertebrates it filtered from the muddy sea floor.

作为蜥脚类的近亲，当时可以肯定地说它可能是食肉动物，吃它从泥泞的海底过滤出来的微小无脊椎动物。

What the researchers could tell was that this creature was a marine reptile that would've been about 3 meters long and that it was likely a close relative of the sauropterygians, the group that includes plesiosaurs and pliosaurs.

研究人员可以判断的是， 这种生物是一种长约 3 米的海洋爬行动物， 很可能是蜥龙类的近亲，蜥龙类包括蛇颈龙和上龙类。
