Tar Pits are pools of, well, tar (A sticky black liquid somewhat similar to quicksand) that you can usally find Diplodocus in. You can use the diplodocus' long necks to get across some tar pits.Other tar
A Braichosaurus in a Tar Pit
pits, however, have no diplocodus in them and consist only of the tar itself and rocks. When encoutering these tar pits, the player must jump from rock to rock across the pit. If a player is to miss the rocks and land in the tar, the player will not sink in and die (unlike the diplocodus and Braichosaurus in some tar pits, however you will die if you are in tar and are hit by the wall of doom) and are still manuverable, but will move much slower than usual. The better the speed, the faster you move in tar pits.
Actual Tar Pits
The real life tar pits are actually a "death trap" for any animals that mistake it for a body of water or the corpse of an animal as a so-called "easy lunch"(called a predator trap) because the asphault forms a black, sticky liquid that is thick enough to trap even mammoths into it's relentles grip and kill them eventually. Then said victim would be added to it's collection of skeletons and can be used as bait so that the carnivores would fall for it's attractions and end of trapping itself mistakenly. The most famous tar pits are the Le Brea tar pits of LA. It is debatable if tar pits really existed during the times of the dinosaurs because evidence shows of pits of very thick, sticky mud that would do the exact same thing to the dinosaurs, such as the Cleveland Dinosaur Quarry & the Gobi Desert dinosaur death traps. It is strange that the player's dinosaur is able to safely walk in the tar pits while the Braichosaurus and Diplodocus are seen trapped by them.
