Foo - What animal is this?

I found this in the desert of south east Utah. Notice the broken-off tusk (not tooth) coming out of the bottom of the jaw. I've also shown the other tusk, which I found unbroken.
.
What animal is this?

i would guess boar or hog.

i would guess boar or hog.
But look how small it is... does an infant boar even have tusks?

not sure, could be two different aninals
maybe the hog tusk and somehting he ate?

¡El Chupacabra!

The 2 tusks are identical. The unbroken one would be recessed a long way into the jaw. Thanks for thinking about it....

The "tusk" is just a big tooth. Probably a rabbit or something with huge incisors.

The "tusk" is just a big tooth. Probably a rabbit or something with huge incisors.NO, definately not. The tusk emerges from a long horizontal recess in the bottom of the jaw... totally different that a tooth.

Shrew.

Hang on a sec...

X-ray of a rabbit:

The incisor and structure of the jaw are almost identical to your's.

Rabbits don't have evergrowing teeth...it has to be a rodent.

I don't follow.

Oh wow. I think you nailed it. I thought that anything considered a tooth would emerge froom the top of the jaw, like the molars.

Thanks. This has been puzzling me for a while.

I don't follow.


No, I see your proof. You are right.

I was following the logic of dead rodents found with oversized teeth due to lack of chewing material, that eventially die from dental-related problems (Biology 101).

Rodents teeth never stop growing.

rabbits are rodents

rabbits are rodents

Rabbits and hares were formerly classified in the order Rodentia (rodent) until 1912, when they were moved into a new order Lagomorpha. This order also includes pikas.
Though members of order Lagomorpha can resemble rodents (order Rodentia), and were classified as a superfamily in that order until the early twentieth century, they have since been considered a separate order. For a time it was common to consider the lagomorphs only distant relatives of the rodents, to whom they merely bore a superficial resemblance; however, genetic studies have since shown that, while still distinct from rodents, they are indeed very closely related after all.
Lagomorphs differ from rodents in that:

they have four incisors in the upper jaw (not two as in rodents);
they will only eat vegetation (unlike rodents, which will eat meat and vegetation)
the male's scrotum is in front of the penis; and
the penis has no bone (baculum) unlike the rodent penis.
They resemble rodents, however, in that their teeth grow throughout their life, thus necessitating constant chewing to keep them from growing too long.

Explodicus pupithicus. Can't believe jsharr missed that. :eek:

I didn't have the connection between the lagomorph distinction and dental growth factor readily in my brain.:(



Sorry.:o Thanks for the correction.

For shame!

woohooo

6 years and a degree in biology and I actually got to put it to use for something :D My Mom will be proud :D


But the internet explains it much better than I ever could!

I guess the "hick knowledge" I have acquired while living in MT has served it's purpose.

We win!

I assume you agree that its a rabbit... the xray sure tells a tale...
.
Also: is the orange patina on the tooth normal on a living rabbit?

;) yeah, the orange is from all the carrots.:D

It's obviously a jackalope (http://en.wikipedia.org/wiki/Jackalope), or more specifically, Jack Ching Bada-Bing (http://en.wikipedia.org/wiki/Jack_Ching_Bada-Bing).

Yes, the Utah desert is positively bursting with carrots. and broccoli.:)

That's from licking that orange dirt off their paws :)

A peccory,it could be a pig too. Pigs,if left feral, grow tusks and a thicker coat of hair inside a year, especcially males.

It'd be a helluva small pig.

its obviously a baby liger tooth i don't care what everyone else thinks

Could have been a chicken. Oh wait, do the chickens have large talons?

They resemble rodents, however, in that their teeth grow throughout their life, thus necessitating constant chewing to keep them from growing too long.

i was taught in middle-school that a defining characteristic of rodentia is that their teeth have no roots and continuously grow.


next thing you're going to tell me is that the daddy long-legs isn't the most poisonous spider on earth!

i think that's from a midget desert hippie.

the tusk was part of a cheap necklace bought at some junk store.

Believe it or not there is more education to be found AFTER middle school.

Rabbits are lagomorphs and their teeth do grow continously.

Not often you read that from you, actually it's not often you're on that end of the equation though!:p
