Leaf or shell?

A friend picked up a fossil on the beach at Fossil Island, Alaska about 15 years ago. 

He's always thought it was a leaf, but I think it looks more like a shell.

Looks geological to me, although more pictures could change my current opinion :)

If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM!

Agreed.

Another possibility is that it's the result of previous collection activities, but didn't make the cut when in came to carrying it home for someone else.

I'm with the others on needing sharper images, but I dont think plant and do think organic--possibly Cretaceous/Jurassic in age. Because of the distinct ridges I was thinking initially ammonite but right now my best guess is you have an Inoceramid type bivalve/clam showing fragments of side by side valves. Here's a similar type Buchiid type bivalve/clam from Northern California that shows similar shell structure/arrangement and an Inoceramus from South Dakota for comparison.
