Ice Age

In Carnivores Ice Age, the Archaeopteryx is an Ambient Animal that does nothing but fly around the landscape and screech. The Earth Archaeopteryx lived in tropical locales and was probably unable to survive in colder climates. It was also probably not an active flier, instead gliding between trees and the ground with occasional flaps to help gain and maintain altitude. By comparison, the Archaeopteryx found on FMM UV-32 seems to live almost exclusively in sub-polar and polar environments and spends pretty much forever in free flight.

In Carnivores Ice Age, the Brontotherium is the first and cheapest animal available to hunt, and is the second largest herbivore in the game. However, in the game, the animal is covered in fur, when in real life Brontotherium was probably covered in a hard, rhinoceros-like skin. Although it is classified as not dangerous in-game, it can still kill the player by trampling him with its massive forelegs, which resembles CPR. This also occurs with the giant deer. It is possible to be confused with the Woolly Rhinoceros or the Mammoth from a distance, but this is unlikely due to differences in size and shape.

In Carnivores Ice Age, the wild boar is the second animal available to hunt. It will attack the hunter if wounded or cornered, then it impales the hunter and shakes him around on its huge tusks. Similar to the case between Gallimimus and Velociraptor, the pig could be mistaken for the wild boar, but not as likely as the animals mentioned before. It is easier to tell them apart at a distance due to the large difference in overall size and skin color. It is also the only modern animal available to hunt.

The wolf is the second most aggressive carnivore in Carnivores Ice Age, and is third animal available to hunt. It roams the landscape howling for its brethren, then attacks and tears any unlucky hunter to shreds. The wolf will charge the hunter at close range swerving in a zigzag pattern similar to the smaller carnivores noted above, and will jump at the player with a loud bark when at close range. It may flee if it somehow misses pouncing on its target, and it scares easier than most other carnivores. Firing a DB Shotgun at close range will get it to charge, while a medium to long range shot will cause it to flee. The Smilodon behaves similarly to the wolf.

The woolly rhinoceros (shortened to woolly rhino, or just rhino) is the fourth animal available to hunt. It is dangerous when cornered or surprised, and will gore any hunter that gets too close with its sharp horns. It is also commonly seen while not being hunted.

The giant deer is available to hunt in Carnivores Ice Age after the player earns 100 credits. It is normally peaceful, but incorrectly stated as "not dangerous". At close range, the giant deer will gore the player with its huge antlers and shake him like a rag doll. It is also one of the weakest creatures in the game, capable of being brought down with a close shot of the X-Bow, Shotgun, or DB Shotgun. In Carnivores: Ice Age, the giant deer can be brought down with a single shot from the X-Bow at any range. In the original PC version, it takes about two shots.
