I have always liked this eurypterid due to its bizarre shape and the fact of being the last one to survive, so why not review it? I'll try to take a look to the article between Tuesday and Friday.

However, I have a point for now. There is a cladogram representing Campylocephalus oculatus as the sister taxon of a clade formed by Hibbertopterus and Cyrtoctenus in
this paper, it would be good to add it to the article.
I don't think we have the telson. C. oculatus is a carapace and some segments, C. salmi is two fragmentary carapaces and C. permianus is another carapace.

I am not sure if it is necessary to cite the ICZN, but that depends on you.
Waterston (1958) specifically mentioned it conflicting with "opinion 65" so I figured that it would be worthwile to include what opinion 65 is.

"named as a species of the related Hibbertopterus" I think that with the previous paragraph it is clear that Hibbertopterus and Campylocephalus are related forms.
Those two were the most important. I would also link exoskeleton, segment, specific name, preoccupied (name), concave and convex, family, type species, genus, dorsal and ventral, phylogenetic, synonym, spine, superfamily, suborder, order, arachnid and footprint, as well as Scotland. Obviously it's not necessary to link all these words, but you could select some.

And it would be nice to try to find something about the name Campylognathus, but it will not affect the review if you don't get anything. I think it's mentioned somewhere in Wikisource, but it's not very useful.
I did find a mention in Wikisource in what looks to be the original description of it (it's by Diener) but it doesn't look like he mentions anything useful such as his reasoning behind changing the name or anything relating to that at all, I could have a second look in a bit but I'm unsure if there's much to gain from adding anything from it.

Passing now, I don't find any other problem. Congrats! And out of curiosity, will you work on the rest of the hibbertopterids?
