There are some unidentified species. For example, the heads and skulls in the Trophy Room of the Los Angeles hunting party's Mother Ship. One of them was a Tyrannosaurus-like creature with a second lower jaw and dreadlocks, possibly a Galar. Another skull on the wall was that of a Yautja-like creature with no eyes, possibly a Predox. Next to the Xenomorph skull there was also a skull with ridges and bumps. And other, dinosaur-like extraterrestrial skulls, including that of a triceratops.
