Revealing mistakes 

When Miller gets cocooned and kills the first face hugger, he fires six shots from Verheiden's Desert Eagle. After Miller realizes he's in trouble and the shot pulls back into the hall, he fires six more times before he screams. The maximum magazine capacity for the Desert Eagle is nine shots for the .357 Magnum.

Anachronisms 

Sebestian sets the clock on the sarcophagus to October 10, 2004 - 10/10/2004, because the Aztec calendar was supposedly based on 10's (the decimal system, erroneously called "metric" here). Yet, why would an Aztec civilization set a calendar to align with the Gregorian calendar, which is what our modern calendar is and wasn't developed until centuries later by the Romans? The Aztecs would not recognize what we call "October" as the 10th month.
In the movie the whaling station was abandoned in October 1904, when in fact it wasn't until the following month that the first whaling station, Grytviken (Cauldron Bay), was established in the Antarctic, and not at Bouvetøya, but in South Georgia. Modern whalers didn't reach Bouvet until the 1928-29 season, and these were operating with factory ships offshore. In 1928, the UK waived its claim on the island in favor of Norway, which had occupied the island the previous year. In 1971, Norway designated Bouvet Island and the adjacent territorial waters a nature reserve. Since 1977, it has run an automated meteorological station on the island.

Character error 

Sebastian erroneously says that the Aztec calendar was metric (he means based on 10, which is not "metric", but "decimal"). In fact, the Aztecs had two calenders and neither was decimal. One was vigesimal (based on 20) with twenty days in 13 "months." The other was a 365-day year count.
Graeme Miller's description of the aurorae as being caused by protons and electrons in the atmosphere is inaccurate. Aurorae are caused by the interaction of high energy particles (usually electrons) with neutral atoms (oxygen, nitrogen...) in Earth's upper atmosphere. However, as a chemical engineer, his knowledge of atmospheric photochemistry may be expected to be somewhat rusty.
Sebastian refers to "the Long Count" while describing a calendar that he refers to as "Aztec". The Long Count was a feature of the Mayan calendar system; the Aztec calendar, although based on the Mayan, didn't use the Long Count.
The date for the exploration is suppose to be Oct. 10, 2004, yet the camcorder used by one of the scientist shows the date as Oct. 8, 2004

Continuity 

When Alexa is climbing the Lho La ice fall in Nepal, you can see a overview of the edge where is climbing to. There is nowhere a helicopter too be seen, yet after 30 seconds (duration of the phone call) the helicopter manages to land, turn off the engine (spinning down rotors takes much more than 30 seconds), and let Maxwell Stafford out of the helicopter and walk towards the edge to meet Alexa, all without her hearing or noticing a thing.
Alexa's "warrior" marking on her left cheek disappears in overhead shots.

The Predator cuts off the tip of the Alien's tail, spewing green acidic blood, and then tosses him through a column and into another room. As the Alien flies in slow motion, you can see that there is no blood on his stump, but immediately after, it's covered again.

When Lex catches the alien on the spear, it swings its tail at her and punctures the wall. Then the camera cuts back to the alien for a split second, then back to Lex as the alien attempts to hit her on the other side. You can clearly see that there's not a scratch on the wall that was just punctured.

When gutting her kill in order to give her the skull to use as a shield, in the very first shot the alien about to be gutted is clearly "grid". The shot cuts back to Lex and after that all shots of the gutting are of an ordinary alien.

Errors in geography 

The captions show the icebreaker approaching the island/pyramid from the Ross Ice Shelf. The island is in fact on the opposite side of the Antarctic continent.
In the unrated edition of the film, a satellite focuses in on Bouvet Island, but in that scene, the island is erroneously situated in the approximate location of Peter I Island, which is quite a distance from the actual location of Bouvet Island.
The penguin lurking in the abandoned Antarctic whaling station is a Humboldt penguin (Spheniscus humboldti), a species found in coastal Peru and Chile - not the Antarctic region.
The satellite images show a large island west of the Antarctic Peninsula, no such island exists.
According to the flashback scene, the man-made pyramid's surroundings were at one time covered by lush warm-climate vegetation. Given Antarctica's climate history and the age of the human species, there was never a time when existing humans would have found any such vegetation in Antarctica.
The island is referred to as "Bouvetoya Island" (the English name is Bouvet Island, "Bouvetøya" is Norwegian for Bouvet Island) but the real Bouvetøya is much further north and east than the satellite images suggested.

Factual errors 

Icebreakers have round prows, not angled ones.
The story is set in October (spring in Antarctica). It should therefore be daylight on the surface, and yet it's dark as night.
In the movie, nearly complete whale skeletons are shown around the whaling station, when in fact carcasses were normally towed offshore by the whalers, and the only bones that would have been seen were a few rib or jaw bones that had washed ashore near the flensing plan of the station, not within the station complex itself.
As the Predator ship passes by the Moon on its way to Earth, we can see the far side of the moon lit up, so from Earth it should be a new moon or at least a crescent. Yet, minutes later, it's a full moon.
Lex says that the pyramid would be directly underneath the whaling station, but the hole made by the predators is at an angle that would put the pyramid almost 3/4 of a mile away from the whaling station.
There are cobwebs inside the pyramid but there are no species of spider that live in Antarctica
During the space-shot of the predator ship shooting a beam to "drill" a hole to the pyramid, we see a beautiful shot of the Earth from space. However, we can clearly see both the day-lit side and the night-side. In reality, if we were looking at the Earth from space, we would only see the lit side while the night side would be completely dark (for example, look at any picture of the Earth as seen from the moon).
When Alexa Woods is climbing the Lho La ice fall in Nepal, she's about 10 body-lengths from the top edge. From the moment she answers the phone she reaches the top in about six steps. You can't take steps longer then your body.
The full moon for October 2004 was on the 28th, not the 10th.

Incorrectly regarded as goofs 

When the expedition first reaches the hidden pyramid, one of the characters examines the wall markings after rubbing away the cobwebs from the stone. Are there any spiders that thrive 2000 feet below sea level in Antarctica? Spiders and other arachnids have been known to survive in extremely hostile environments, including at high altitudes, in climates of intense cold and where food supply appears to be scarce. The climate inside the pyramid was warm enough that the humans' breath did not condense. Other survival factors may have been present. Also, the material may have not been spider webs, but strings of dust and particles accumulated over time.

Plot holes 

It's claimed that the pyramid will move every ten minutes because the Aztec calendar is based on the "metric system". Time measurement has nothing to do with the meter. What he means is the decimal system. Modern measurement of time (24 hours in a day) is not decimal. Thus, each Aztec hour should be around 2.4 hours (1/10 of the day). As such, it would be more probable that the pyramid would move every 14.4 minutes.
When Sebastian is translating the hieroglyphics to Alexa, he reads that everything was destroyed and that nothing survived, among other things. If this is true, who could have possibly carved the hieroglyphics into the stone?
At the end of the movie, the predator fighting the mother alien is speared through its chest with the tail of the alien. As the predator has already been infected, this wound would have killed the alien in its chest.

Revealing mistakes 

When the first-killed Predator is thrown to the ground, its extended wrist blades bend when they hit the ground, revealing that they are actually made of rubber.
Alexa is wearing only a thin sweater (and no hat) after the Alien burns her jacket, yet she doesn't even shiver while outdoors in Antarctica.
The legs of the practical and computer-generated Aliens don't correspond. The practical ones have human-like joints and feet, while the CG versions have an extra joint at the ankle and much longer toes.
During the first battle, when the Alien falls to the ground after the Predator kicks it through a pillar, a wire can be seen holding its tail up.
When Alexa enters the egg chamber, she sees the face hugger at Miller's feet. The face hugger is missing the huge bullet hole that was there after Miller shot it with his first six shots.

Spoilers 

The goof items below may give away important plot points.

Continuity 

When Alexa and Scar are on the sled trying to get away from the bomb, Alexa is holding on tight with both hands. When she jumps off the sled and runs, she has the head shield on her arm, covering her hand. She wouldn't have had time to pick it up once the sled stopped.

Continuity 

The second Predator is killed by an Alien when his head is punctured by the Alien's inner mouth. When the shot changes and the Predator tilts his head back there is no wound.

Continuity 

In the scene where Alexa and the Predator 'Scar' find Sebastian all the eggs are open and presumably empty, but when we see from the Predator's view the eggs are all closed and facehuggers are preparing to emerge.

Errors in geography 

The film gives confusing and inconsistent accounts of geography of the island and the pyramid. The pyramid is supposedly under 2,000 feet of ice, yet the tunnel leading down to it begins at the (sea level) whaling station. The geographical survey (as well as the obvious in-story shots) show that the ice tunnel slopes gently down towards the pyramid entrance, therefore not on top at all. The whaling station is thus supposedly built on ice instead of rock; this is a ludicrous proposition as it would only be constructed in a region where ice melted enough each summer to allow whaling ships to dock. Anything built on ice that thaws significantly each year would not last 100 years. This arrangement also places the pyramid and a large amount of ice below sea-level; the buoyancy and natural flow of the ice pack makes this highly unlikely and is not something that could be accurately described as an island in the first place. The top of the tunnel is at the whaling station and descends at a "perfect 30 degree angle" to the pyramid (thus placing it over half a mile away horizontally, you'd travel 3464 feet horizontally), yet we are told satellite imagery shows that it is directly beneath the whaling station. Further confusion is caused by the scene at the end of the film in which a large tank falls into the water and plunges hundreds of feet towards an unseen ocean floor, supposedly directly offshore.

Revealing mistakes 

At the end of the movie when the four predators carry the body of Scar (Main predator) into the predator mother ship. You can clearly see the four predators struggling to get up the ramp. In the movie's theatrical release commentary Paul W.S. Anderson revealed the predator suits were "too heavy" and that the ramp was slippery due to a substance being added to the ramp to make it look more shiny.

Revealing mistakes 

When the Predator and Alexa turn around after the whaling station falls into the ground, the shot of them is reversed (notable by the marking and pressure tubes on the predators helmet). When Alexa and the Predator are running from the explosion - across the whaling station - her "shield" changes hands.
