Bone Yard (どたばた ジュラシックぬま lit. Slapstick Jurassic Swamp in Japanese) is the fourth level of the first warp room in Crash Bandicoot 3: Warped and N. Sane Trilogy HD remaster of the third game. Crash finds himself whisked away to an underground swampy forest in the distant prehistoric past, an era still ruled by the dinosaurs. Reigning supreme among the beasts is a fearsome herbivore, the triceratops, which will relentlessly chase Crash through some sections of the level. Other obstacles to avoid include pterodactyls, wave lab assistants, mini-volcanoes, puddles of magma, and vegetation that will slow down Crash.
If the player has retrieved the red gem from Deep Trouble, they can take the red gem path here for a hidden second clear gem. Retrieving it will require the player to survive some particularly tricky chase sequences. However, considering Deep Trouble's placement in the third warp room, it should not be a particularly harrowing excursion for the marsupial by that point in the game.
The two Slot Crates in the level are the only ones in the game that cannot change into Iron Crates, as they will be broken by the Triceratops if Crash does not break them.
At one point during the development of the game, Bone Yard was switched with Dino Might!
This level's secret route was originally designed to be entered through a death route platform which looks like this picture, but was changed to the red gem path.
In the beginning of the level, the segment near the start where the 3 crates are before you get chased, there are some broken planks of wood bark one the left side of the area you stand. One of the pieces is shaped exactly like the "N" on Cortex's head.
Early footage of the game show that Bone Yard also used to have a Baby-T egg at first. It was located in the middle of the second side-scrolling part of the level. However, the idea ended up being removed and placed in Dino Might! and Eggipus Rex only.
