Yeah.

As a person who's also pretty interested in arthropods and mollusks, I like to look at what happens to stuff like Anomalocaris, Cameroceras, Pterygotus, Meganeura, and Arthropleura.

The 2013 Cambrian paper said that at least Anomalocaris canadensis would have been capable of durophagous predation on trilobites (while Anomalocaris briggsi most likely fed on soft-bodied organisms).

The 2015 arthropod paper said that Pterygotus anglicus and Jaekelopterus rhenaniae had reasonable eyesight and claws designed for crushing bones and exoskeletons, while Erettopterus ossiliensis and Slimonia acuminata had OK eyesight and claws designed for getting a hold of struggling prey, and Acutiramus cummingsi had terrible eyesight and claws designed for slicing soft-bodied organisms.

And that's how I happened to derail the topic of this thread.
