Goof: At the end, when Maggie and Quinn land in the futuristic world, Quinn concludes that they've gone into the future, although he has previously stated in such episodes as "The Guardian", that they cannot travel in time.
As Quinn says, this isn't the first time they have encountered dinosaurs. The first time was in the episode "In Dino Veritas".
Goof: When Rickman injects himself with the villager's brain tissue, Rickman's face morphs into the villager's face, along with the villager's hat. The hat isn't part of the villager's DNA, so it shouldn't have appeared in the morph.
When the group is introduced to D squad around 7 minutes in there is a cinema in the background showing Back to the Future 4.
At the beginning of the episode, the four Sliders jump into the vortex, which is off screen. When Quinn jumps, he is clearly seen landing on the ground, getting up and walking away.
Nitpick: When Maggie breaks the man's arm, no snap is heard. If she really did break his arm in two there would be a sound.
Nitpick: When the scene shows the bodies outside the gate, it's interesting to note that there's no sign of the violence Rickman ordered. No bullet holes in the clothes; no blood on the ground.
Goof: In "Exodus" (Part 1) they said that radiation would kill all plant and animal life, but structures would remain intact. However, the planet exploded.
All officers must pass a qualification test with firing a pistol. Maggie couldn't qualify since she doesn't even know how to hold the pistol properly.
Nitpick: Maggie's Marine service alpha uniform bears a sharpshooter rifle badge, but not a pistol marksmanship badge. This is odd, considering that's the weapon she's carrying and that she is an officer in the Marine Corps where pistol training is required.
The timer that they have been using since the beginning of the series is now useless. They begin to use a new timer to slide with that is based on the Egyptian technology.
In the end sequence, Quinn goes into the house and comes out three seconds later. He then tells his friends that he told the housewife they were aliens. However, it takes him at least twice that long to repeat what he told the housewife, and that doesn't include the time to take the cassette out of the video camera. He wasn't in the house that long.
In the end sequence, a normal-sized woman with human-colored skin videotapes the sliders as they arrive. However, when Quinn describes her a minute later, he says that she is "short, green, and moldy."
Nitpick: When Quinn knocks the CCTV camera off the wall, it can be seen that it was not attached to anything.
Nitpick: While Quinn is sword fighting near the end of the episode, a cameraman's camera and arm are visible on the left side while he is filming the fight from another angle.

Outer Limits, Aquarius, Lost City, Eden, Dry Gulch, The Sand Pit, and Outpost are locations listed on the map.
Trivia: This is the only episode in the entire series with no sliding scenes.
Trivia: The idea for this world is based on physicist's Herbert Van Meer idea. He postulated that the Earth could rotate on its axis slightly faster, and yet complete one solar revolution in the same amount of time. Over the course of billions of years a time lapse would occur due to gravitometric forces. The result is that the events that took place 12 years ago on Earth Prime take place here in the present,
