Westicspinus canadensis
It's built entirely on the idea that this hypothetical Spinosaurine was found in British Columbia, somewhere outside Vancouver or EDMONTON!!!!!
Seeing as how (aside from Antarctica) Spinosauridae are literally on every single continent.
It'd likely be a moderate 6.9-9.2 metres long, and would probably be built similar to Irritator challengeri. It's name would center around this location, meaning "The Canadian Western Spine" I'd imagine it as using those serrated teeth, to clamp then slice pterosaurs. Since having serrated teeth wouldn't help with fishing. I could see them using the teeth to quickly slice it up and kill it, and possibly hunting flocks of pterosaurs in groups of 2-3.
