Even a single spinosaurid was big enough to 'muddy-up'* a fairly large water
body; a very effective way of obtaining fish in shallow bodies of stagnant or
slow-moving water, and something long jaws and conical teeth would be
Perhaps large lungfish would be merely forced to the surface(?), but would
still be easy pickings. [Actually, even sauropods were _theoretically_ capable
of obtaining fish in this manner, given a shallow pond w/ a silty bottom.]
Hmmm. Wonder if the Nile Perch was present; now there's a mouthful...
*Definition -- to raise enough silt off of the bottom to clog the local water
column, at which point gilled creatures that can't escape to clear water pass
out (hypoxia), often floating belly-up.
