Blood from the remains of an extinct fish make animals and people revert to their prehistoric ancestors. Director Jack Arnold hated this film and it's easy to see why. The script is pretty dumb but it's done very seriously and there is a good performance by Arthur Franz. There's also a little surprising amount of extreme (for the time) violence when a man gets hit with an axe. Unfortunately, the monster makeup in this film is terrible--the prehistoric dog just had big fangs...the giant dragonfly was so obviously a plastic dummy...and Franz (or a stuntman) is very obviously wearing a cheap, ridiculous-looking rubber mask at the end. So, it's OK but you're not missing anything if you skip it.
