Check out those massive infraorbital foramen, humans have them as well.
Can we all agree “bouquet” is an upsetting term in reference to a bundle of nerves

Its time for this week's answer to #GuessTheSkull!
This week's #Skull king of the jungle, one big ol' kitty, Africa's very own Panthera leo! The African lion (modern) hence the kittens in mittens comment.
Good job to everyone that got it, it was tricky!
So why not a bear?

You can be forgiven for thinking it was a bear, forward facing eyes, tooth size and massive jaw muscles make for similarly shaped skulls. One of the best ways to tell the difference is in the nose... Yara say what? Nose full of bony turbinates, but they vary in shape!pic.twitter.com/j1POCzrYmF
Bear=Branching tree like turbinates
Lion= Scroll like simpler turbinates
Sooo What are these nose scrolls and what do they do?

Turbinates are the complex made of both the bone and the epithelium that covers it. They come in a multitude of complexities, ad honestly these sections are beautiful. Paper here:https://bit.ly/38QPmU1 They control humidity and temperature of the air coming in and out!pic.twitter.com/QfVfosDfb7
Both birds and mammals have complex turbinates, likely due to their endothermy (warm blooded) and increased ventilation rate. Water retention is important, and dry air can be detrimental to mucosal lining of .. well your insides.pic.twitter.com/E9mzmcJFVx
So for a long time it was thought that turbinates were linked to warm blooded-ness and water retention. BUT CROCS THO! Crocs have "proto turbinates" in their nasal passages that do not seem to aid in heat exchange! Paper:https://bit.ly/38QPmU1 pic.twitter.com/tM1nF1MBL5
Soo if an extant cold blooded animal suggests has these primitive turbinates, maybe the original role of turbinates was not related to heat or water conservation.
Instead it is hypothesized that initially they evolved to assist in brain cooling, but were adapted by co-evolving animals to aid in heat and water conservation!

Whooops! I bet you thought I was going to teach you about lions huh.. nope weird bony noses.
Never know what you are going to get with #GuessTheSkull!!
Thanks for everyone who plays every week, you can support Guess the Skull by keeping me caffeinated: http://Ko-fi.com/yaraharidy pic.twitter.com/PqXf9oaHhm
