Hey Amanda, here's a link to an article that gives photo credit for an image we were thinking about using. Do you think we can use it if we properly cite the photographer? http://www.iflscience.com/plants-and-animals/why-giraffe-gnawing-impala-skull — Preceding unsigned comment added by Tmeister21 (talk • contribs) 20:52, 6 November 2015 (UTC)

Hey guys! Great job! I would go more into the evolution of osteophagy though. It seems like it is a newly observed behaviors (you mention it began in the 1800s, or at least when it began to be documented.) Is there no earlier evidence of osteophagy in the animal kingdom? . Also, it is mostly seen in herbivores, so how is the bone chewed if their teeth are not "cut out" (no pun intended) to consume such hard substances? I would also elaborate on this sentence: "This low protein availability is often the case prior to green-up in ecosystems" I don't know what green-up is referring to. I would also elaborate on this sentence: "Unlike phosphorus in most animals, pica is associated with iron deficiencies in humans." Why is it associated with iron deficiencies? How does that relate to osteophagy? Great job other than that!

Saw that this page is a bit sparse, but wasn't sure if the incidents with the sheep on Foula, Scotland and the deer on Rum, Scotland truly count as osteophagy...

in "Feeding behaviors" this is classified as a herbivorous behavior. not sure if the eating of bones is supposed to be there. it sounds like carnivorous behavior to me — Preceding unsigned comment added by 83.86.208.245 (talk) 11:02, 7 February 2014 (UTC)

Hey guys, I made a couple of rewording/grammar changes. Oh and also the domestic dog page needs citations. Personally, I think it'd be cool if you could elaborate a bit on the dog portion since that's such a common thing we see on a regular basis. Unless of course there really isn't any further literature, then it's alright. I think I also read somewhere that elephants tend to eat chunks of soil since they lack nutrients. That fits more under geophagy so maybe that could be an example you could provide. One more thing you could elaborate more on are the physiological effects of phosphate deficiency. I've seen it mentioned a couple of times and I'm still not quite sure what problems not getting enough phosphate could result in. Maybe a small section on that or some brief mention of it with a link?

Good stuff overall!

Hi guys, so I made a few small word/grammar changes. I agree with all of the above suggestions. I think you have a lot of good examples of animals practicing osteophagy, but your article could really benefit from more of a description of why they do this. I don't think it would be too much to add a short paragraph about the physiological effects of phosphate deficiency, why an animal's own bone metabolism is not sufficient, why some vegetation lacks phosphate, etc. Also, your examples are great but they seem a little like they were written by different people because they state things we have already ready either in the introduction or above in another example. Maybe you could prune some sentences in the later examples so the whole thing reads more cohesively? Lastly, the human examples are definitely interesting, but it might be good to see some discussion of the evolutionary root to pica. Overall nice job! Aewells14 (talk) 14:49, 5 November 2015 (UTC)
