A Sound of Thunder
Detailed plot on Wikipedia here.
"Ryer and Rand lead a group through the city - now filled with evolved
and deadly Baboonlizards and other new hazards that kill some of their
party members - to find Eckels and Middleton. Eckels is safe but
asserts he remained on the path, while Middeleton, poisoned by the new
wildlife, takes his life before they can stop him. However, they are
able to find a dead butterfly on the sole of the suit he used for the
safari. The party make it back to Time Safari after more time waves
hit, now finding the time machine partially underwater and unusable.
Rand obtains the hard drive containing the TAMI software with plans to
use it with the nearby university's particle accelerator as a
substitute time machine.
Ryer and Rand are the only two survivors once they finally make it to
the university, Rand noting that the appearance of simian-like
Babboonlizards from the latest time wave means the next one will wipe
away humanity. Rand prepares the accelerator and stays behind while
Ryer goes through the time portal, just as the last time wave hits
turning Rand into a humanoid catfish-like creature. Ryer catches up to
the previous expedition, catches Middleton to prevent him stepping on
the butterfly, tells Jenny the bio-filter is off at the same time
asking her to give his earlier self a recording of the events he has
witnessed. The expedition returns without incident to the future they
had left. Ryer shares the footage with Rand."
