Dr. McCoy, aka Bones, has a couple of weird skulls in his office, as seen in the following picture from the episode "Is There in Truth No Beauty?" (they are highlighted with red arrows and the frame is from around the ~47:21 mark):

enter image description here

They definitely look non-human and are probably not from any other Federation species we have seen in the series, so my question is: which species are the skulls from?

In-universe answers are preferable, but out-of-universe trivia about the props might be considered as well.

    The white one looks a lot like an orangutan skull

    It also looks like a troll skull from Skyrim ( elderscrolls.fandom.com/wiki/Troll_Skull_(Skyrim) ) but that's another franchise :D

    forgottentrek.com/forgotten-aliens-of-the-motion-picture the black one is possibly Zaranite - they have that dual lobe skull in-universe though obviously the new aliens of TMP have little to no connection to TOS out universe. So I don't think a factual answer is possible. Dec 5, 2021 at 8:46

    The white skull looks felid. I suspect they were going for Caitian. Apr 1, 2023 at 0:28
