This is kind of similar to the recent "anting _Caudipteryx_" discussion. Something just occurred to me today when I was watching a nature show. It showed footage of a shark with a remora hitching a ride on it. It made me wonder: how plausible is the idea of seeing ancient marine reptiles with remoras in tow? Now, I don't know if remora fossils, or even fossils of that fish group have been found in Mesozoic beds (any palaeoichthyologists out there?), but there might have been some other kind of fish filling a similar role. Just something to think about, and something for palaeoartists to consider (if they have not already; I at least have never seen a painting illustrating this idea).

"...I suspect he actually has a subspecies of _Stenonychosaurus_, though I
haven't decided for sure...small Triassic carnivore--two meters from pes to
acetabulum. In point of fact, a rather ordinary theropod..." -from Crichton's _The Lost World_
