Though it's sadly unlikely for Cryolophosaurus since unless I'm mistaken it doesn't have asymmetrical ears. |

Actually, they do, besides theres no use for a facial disk if you don't have assymetrival ears for amplification. Spoiler: click to toggle Besides, Cryo is a basal tetanuran i doubt it had any feathers at all Edited by Ignacio, Oct 6 2014, 03:12 PM.

Possibly protofeathers, especially when you take into account the fact that it lived in a cold climate. It probably looked more conservative than that owl-like reconstruction though IMO. |

I found it searching for frogmouth skull lol, besides tberes a serious lack of frogmouth ct scans sadly Tough as far as we know, they do have assymetrical ears Edited by Yi Qi, Oct 6 2014, 03:13 PM.

Well I know owls are the only tetrapods (other than troodontids) with asymmetrical ears (going off of what Darren Naish said), which is why it was such a big deal that troodontids have them too. However, I'm not sure if that applies on the bone level only or if it applies for external skin too. Either way, frogmouths don't have asymmetrical skulls, but they might have asymmetrical skin.

Also the blog post that you linked before, while adressing the similarities between owls and troodontids, never says that they should've looked like owls. In fact it says that there were anatomical differences between the ears of troodontids and owls, and that the fact that they both have asymetrical ears is proof that they probably had a similar hearing sense and probably used them to locate mammals underground. So it just says that they could have had similar strategies to locate prey but not because of that they looked the same ![]() Now i don't know much about birds anatomy (clearly) but why having asymetrical ears equals having a facial disk? How does the facial disc complements the asymetrical ears? And could animals would asymetrical ears lack a facial disc? (real questions) |

The sound travels in a facial disk in a way that it circles around both oddly placed ears amplifying the sounds as a megaphone. Assymetrical ears would be of no use without a facial disk because they'd lack the megaphone effect so usefull for nocturnal animals, without a facial disk there would be no need for assymetrical ears Really, just try to interpret both the ears and the disk as a single hearing aparatus.

*tries hard to ignore the oviraptors near the rex* thats not entirely true that asymmetrical ears would be useless without the disc, they just wouldn't be as useful as with the disc (but the same goes for all bird and reptile ears) also, feel free to correct me if I'm wrong, but I didn't think all owls had asymmetrical ears? |

Yes, asymmetrical ears evolved independantly in many owls. Not all of them have them.
