New Members Ozie Posted March 28, 2022 New Members Share Posted March 28, 2022 (edited) Hey all, I have another bone identification I need help with. I have these odd looking rodent skulls (I assume rodent because of the large incisors). I have seven of them total, the smallest being 2 inches (5cm) in length, and the largest being 4 inches (10 cm). All of them have that exposed sinus cavity and rounded orbital. Any idea what they could be? Best bet is a rabbit but I would like to be sure. Edited March 28, 2022 by Ozie Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 28, 2022 Share Posted March 28, 2022 Looks like some sort of Rabbit skull. 1 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

New Members Ozie Posted March 28, 2022 Author New Members Share Posted March 28, 2022 Yeah... rabbit makes sense and I feel dumb lol. I was doing all my research on rodents and it did not even occur to me that rabbits have large incisors but are not considered rodents. Thanks!

SteveE Posted March 28, 2022 Share Posted March 28, 2022 FYI you can rule out rodents because the back side of front teeth is white. Rodents have a softer yellow-brown material back there, which wears away. Since the teeth always grow they keep 'em sharp by gnawing. I don't know how rabbits keep their teeth sharp. Do any of you know? Anyway, I mainly stopped by to share this pdf for your next mammal skull ID 574407801_keyguidemammalskullslowerjaws.pdf 1 Link to comment Share on other sites More sharing options...
Coco Posted March 29, 2022 Share Posted March 29, 2022 OK for rabbit. For your future skulls identifications, don’t forget to show the chewing face of your teeth !

jpc Posted March 29, 2022 Share Posted March 29, 2022 Rabbit for sure. Look behind the front upper incisors... there will be a second set of little incisors. This is diagnostic for bunnies, as is the intricate fenestration (big word of the day) in front of the eye sockets. Based on size... cottontail, not jackrabbit. 2 Link to comment Share on other sites More sharing options...
