The tumblr of Shadyufo. Here you will find dead stuff, art, and dead stuff AS art! As well as a dash of my pets and any wildlife I encounter.
spookients submitted: Was found somewhere in Washington I believe. I forget which trail. A friend stumbled upon it and brought it back to me.
Thank you for any input. :)
Hmmm, that’s a tough one! Looks like a humerus from a young animal (the end caps never fused so they are missing which indicates it was a juvenile) so based on the size and shape my vote would be for deer. Hard to be certain though. Neat find!
The lower mandibles of many species aren’t actually fused together by bone but are connected by cartilage called the mandibular symphysis. The jawbones of cows, all dogs, all cats, all deer, opossums, mustelids, rodents, and many others are held together by this fibrous material so when it rots away via decomp the mandible halves seperate. All of the jawbones pictured are held together only by glue.
Some animals do have jawbones where the bone itself is fused together though. Pigs, apes (including humans!), badgers, horses and a few others all have fused lower jawbones which won’t come apart after decomp.
But early in life the two halves of these species’ mandibles are still held together by cartilage like other animals. As they mature bone takes the place of the cartilage and the two halves become fused.
Here’s an adult pig vs. a piglet. See how the jawbones become fused?
As far as I’ve been able to tell no one really knows why some animals are this way and some aren’t. Could be based on diet and the bite force required to eat certain things. Here’s an interesting little article about it all!
Hey there! Hope you don’t mind if I publish your ask (if you do just let me know!) but I thought you might get a better response if I made this public. I know of lots of Canadian collectors but I’m not sure who has stuff for sale!
Any of you rad Canadian Vultures want to chime in here? :)
