Carthago, Vol. 1

An oil drilling company uncovers a network of big underwater caves with prehistoric fauna, most notably megalodons a.k.a huge ass sharks.

This bande dessinée started off very promising, with some cruel yet beautiful wordless scenes. But then it quickly devolved into pages and pages of boring exposition and when we do get back to the prehistoric sea life near the end, all sense of wonder or horror has evaporated.

There's some small hints of more overt speculative elements besides the surviving megalodons and judging by some of the other covers in the series, that aspect will become more and more important. But I think I'll stop here.
