Nautilus ID and bite mark?

[cen003998]

I preped this nautilus fossil recently,

Wondering if the damage on the shell was caused by predation?

And is it Cenoceras sp.?

Thanks

I think you're probably good with your guess at Cenoceras, since a large portion of Jurassic nautiloids belong to that genus. It sure does look like one to me anyway. As far as predation damage, I couldn't say one way or the other, since it is often the case that the part of the whorls that is missing occurs often just due to circumstances before, during or after burial. I don't think you'll ever know for sure with this one, since there are no obvious marks from teeth or crab pincers on it.
